Answer:
-60x
Step-by-step explanation:
We simply open up the bracket and collect similar terms
So we have;
4(-15x-2) + 8 as:
4(-15x) -2(4) + 8
-60x -8 + 8
= -60x
Answer: 60x
Step-by-step explanation: -60x-8+8=-60x

What is one possible perimeter of the garden, in meters?
Answer:
24.1 is a possibility for the perimeter
Step-by-step explanation:
The third side between 12+0.5 and 12-0.5, or 12.5 and 11.5.
The third side is between 11.5 and 12.5.
Simce it isn't isosceles third side can't be 12.
So it's asking you to choose a number between 11.5 and 12.5 with the exclusiion of 12 for the third side measurement in meters.
So let's choose 11.6.
So the perimeter is just the sum of all side measurements.
11.6+12+0.5
11.6+0.5+12
12.1+12
24.1
24.1 is a possibility for the perimeter
Warren is on vacation and needs to arrange transportation. A rental car costs 40 dollars per day plus a one-time cost of 14 dollars for insurance. Construct a function C(x) that gives the total cost of renting a car for x days. C(x)=________.
If Warren has budgeted 254 dollars for the rental, how many days can he afford?
Answer:
C(x)=40x+14, 6 days
Step-by-step explanation:
C(x)= payment per day*x + initial payment. the payment per day is $40 while the initial payment is $14. so C(x)=40x+14.
C(x)=254=40x+14, 40x=240, x=6
If the length of the shorter arc AB is 22cm and C is the center of the circle then the circumference of the circle
is:
Answer:
176 cmStep-by-step explanation:
The shorter arc is 22 cm.
Arc length formula:
s = πrθ/180Circumference formula:
C = 2πrUse the first formula to work out the value of C:
22 = πr*45/180πr/4 = 22πr = 88 2πr = 176C = 176 cmLength of arc=L=22cm

Which of the lists of letters all have line symmetry?
1. (A, B, C, D)
2. (W, X, Y, Z)
3. (L, M, N, O)
4. (S, T, U, V)
Answer:
The first row
Step-by-step explanation:
Letters A,B,C,D
==================================================
Explanation:
Check out the diagram below to see where the lines of symmetry are located.
For the letter A, we have a vertical line through the center that is the mirroring line. Reflecting one half over that line generates the other half.
For letter B, we have a horizontal line through the center. This applies to letters C and D as well.
This is why answer choice 1 is the final answer.
-----------
For letter Z, we have neither a vertical nor a horizontal mirror line. This letter doesn't have any lines of symmetry (though it does have rotational symmetry). So we can rule out answer choice 2.
Letter N is pretty much the same idea as letter Z. There aren't any lines of symmetry but we do have rotational symmetry. So we can rule out answer choice 3.
Lastly, we can rule out answer choice 4 because letter S has the same properties as letters Z and N.
Which of the following is true about the quotient -2/0?
A.
The quotient is equal to -2.
B.
The quotient is undefined because the denominator is zero.
C.
The quotient is undefined because the numerator is negative.
D.
The quotient is equal to 0.
Answer:
B.The quotient is undefined because the denominator is zero.
Step-by-step explanation:
You cannot divide by zero. Take a piece of paper and divide into zero pieces. It cannot be done as we know it. That is undefined.
The quotient is undefined because the denominator is zero.
Option (B) is the correct answer.

Answer:
eşnatto eşmatoroorlfld
Answer:
Now , Piyush age =3+Honey age
Step-by-step explanation:
Honey age=x
Piyush age=y
1 year ago,Honey age=x-1
Piyush age=y-1
the ratio of Honey and Piyush age=2:3
x-1:y-1=2:3
x-1/y-1=2/3
3(x-1)=2(y-1)
3x-3=2y-2
3x-2y= -2+3
3x-2y=1 eq _1
after 5 years from now,
Honey age=x+5
Piyush age=y+5
the ratio of them=4:5
x+5/y+5=4/5

Given: ALON
LM: NM
LO = NO
MO #MO
M
0
N
Answer:
true
Step-by-step explanation:
We are given that sides LM and NM, LO and NO, MO and MO are congruent. Since this describes 3 sides of the triangle, you can say ΔMNO is congruent to ΔMLO. From this, you can say ∠OMN is congruent to ∠OML. The two angles (∠OMN and ∠OML) form a straight line, meaning they add up to 180 degrees. We can write:
∠OMN + ∠OML = 180
And since ∠OMN = ∠OML, we can substitute and solve:
∠OMN + ∠OMN = 180
2∠OMN = 180
∠OML =∠OMN = 90
Since both these angles are 90 degrees, LN is perpendicular to MO by definition.

The sign at the tee off area for a hole on a golf course indicates the hole is 340
yards from the tee. The golfers drive went to the right. The caddie paced the
drive to be 230 yards. The yardage markers indicate the ball is still 175 yards
from the hole. Determine the angle the golfer went off line from the tee when they
drove the ball.
The angle the golfer went off line from the tee when they drove the ball
is [tex]\phi=28.2 \textdegree[/tex] because the cosine rule has been applied to calculate the angle
From the question we are told that:
Distance of hole from tee [tex]d_h=340yards[/tex]
Distance to the right [tex]d_r=230yards[/tex]
Ball distance from hole [tex]d_b=175 yard[/tex]
Given that the three points form a triangle x,y,z respectively
Where
[tex]d_h=xz[/tex]
[tex]d_r=xy[/tex]
[tex]d_b=yz[/tex]
Using Cosine Rule
[tex]yz^2=xy^2+xz^2-2(xy)(xz)cos\phi[/tex]
Therefore
[tex]cos\phi=\frac{yz^2}{xy^2+xz^2-2(xy)(xz)}[/tex]
[tex]cos\phi=\frac{(175)^2}{230^2+340^2-2(230)(340)}[/tex]
[tex]cos\phi=0.88[/tex]
[tex]\phi=28.2 \textdegree[/tex]
In conclusion the angle the golfer went off line from the tee when they
drove the ball is mathematically deducted and give as
[tex]\phi=28.2 \textdegree[/tex]

Assuming x and y are two odd numbers and x/y is an integer. Which of the following statements are true?
1: x + y is odd.
2: xy is odd.
3: x/y is odd.
4: x-y is odd.
A: 1 and 2 only.
B: 1 and 3 only.
C: 2 and 3 only.
D: 2, 3, and 4 only.
E: 2 and 4 only.
Answer:
C
Step-by-step explanation:
1: x + y is even. Try it. 3 + 5 = 8. 2x + 1 + 2y + 1 = 2x +2x + 2. That's even no matter what 2 odd numbers you use.
2: xy is again try it 3 * 5 = 15 which is odd. (2x + 1)(2y + 1) = 4xy + 2x + 2y + 1. The first 3 terms are even. The last one is odd. So xy is odd.
3. 9/3 = 3. Three should be true. The numerator is greater than the denominator. And x/y is given as an integer. So the statement should be true.
4. x - y is This can't be right. 2x + 1 - 2y - 1 = 2x + 2y. The result is even.

A submarine cruises underwater at 20 km/h and on
the surface at 30 km/h. The submarine travels a.
distance of 650 km in 25 h. A linear system was
created and graphed
Answer:
System of equations:
20x + 30y = 650
x + y = 25
Time underwater = 10 hours
Time at the surface = 15 hours
Step-by-step explanation:
Let x = time underwater at 20 km/h.
Let y = time on the surface at 30 km/h.
speed = distance/time
distance = speed * time
distance underwater: 20x
distance on the surface: 30y
total distance: 650
20x + 30y = 650
total time: x + y
total time: 25
x + y = 25
20x + 30y = 650
x + y = 25
20x + 30y = 650
-20x - 20y = -500
--------------------------------
10y = 150
y = 15
x + y = 25
x + 15 = 25
x = 10

1. You are a contestant on the Wheel of Fun. The spinner contains 4 red panels,
5 yellow panels, a bankrupt panel, 7 blue panels and two free spin panels.
Utilize this given information to calculate the following probabilities:
a. Probability of a spin landing on a red panel.
b. Probability of a spin landing on anything but a blue panel.y that
C. Probability of a spin landing on a yellow or red.
d. Probability of a spin landing on a any non-color panel.
Okay
Answer:
We have:
4 red panels
5 yellow panels
1 bankrupt panel
7 blue panels
2 free spin panels
for a total of:
4 + 5 +1 + 7 + 2 = 19 panels.
And we can assume that all the panels are equal, so the probability of landing on every single one is the same.
a) Probability of a spin landing on a red panel.
This will be equal to the quotient between the number of red panels (4) and the total number of panels (19)
P = 4/19 = 0.211
b) Probability of a spin landing on anything but a blue panel
There are 7 blue panels and a total of 19 panels.
then 19 - 7 = 12 panels are not blue.
The probability of not landing on a blue panel will be equal to the quotient between the number of panels that are not blue (12) and the total number of panels (19)
P = 12/19 = 0.632
c) Probability of a spin landing on a yellow or red.
There are 4 red and 5 yellow ones, so there are 4 + 5 = 9 panels that are either red or yellow.
The probability is computed in the same way as in the above cases, here we have:
P = 9/19 = 0.473
d) Probability of a spin landing on any non-color panel.
The non-color panels are:
1 bankrupt panel and 2 free spin panels, for a total of 3 non-color panels.
The probability is computed in the same way as above, so we get:
P = 3/19 = 0.158
