find z and x
please help i’ll mark the first one or whoever right brainliest
Answer:
z=97 x=21
Step-by-step explanation:
so straight angles always equal 180°
And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z
There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.
Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.
4x+13=97
4x=84
x=21

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends. She will put this money into a 18 month certificate of deposit until she finds the car of her dreams. The CD earned 10% annually and simple interest. How much will she put towards the down payment and 18 months 1.5 years?
Answer:
$3450
Step-by-step explanation:
Here, P = $3000, N = 1.5 years, R = 10%
[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]
Amount of down payment
= $3000 + $450
= $3450

Answer:
What is the constant variation of Y =- 2 3x?
The constant of variation, k , is 23 .
Step-by-step explanation:
When x is zero in a direct variation equation y will also be zero. That means that the y-intercept of all direct variation equations is always zero.

The ratio table below shows the conversion between centigrams and milligrams. How many centigrams would be equal to 0.3 milligram?
Answer:
.03
Step-by-step explanation: because milligrams is 10 times as much as centimeters so if thereś .3 milligrams then you divide .3 by 10 and youĺl get .03

A distrubutor wants to make 1,000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?
Answer:
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Step-by-step explanation:
System of Equations
Let's call
x = pounds of trail mix 5% raisins
y = pounds of trail mix 20% raisins
The distributor wants to make 1,000 pounds of trail mix, thus:
x + y = 1,000 [1]
The mix must be 8% raisings as a combination of x and y, thus:
5x + 20y = 8*1,000 = 8,000
Dividing by 5:
x + 4y = 1,600 [2]
Subtracting [2] and [1]:
4y - y = 1,600 - 1,000
Operating:
3y = 600
y = 200
From [1]
x = 1,000 - y = 1,000 - 200
x = 800
He should use 800 pounds of trail mix 5% raisins and 200 pounds of trail mix 20% raisins
Answer:
5% raisin mix: 800 lbs
20% raisin mix: 200 lbs
Step-by-step explanation:
Let number of 5% be x; and number of 20% be a.
x + y = 1000
5% · x + 20% · y = 8% of 1000 pounds
0.05x + 0.2y = 80
x = 1000 - y
0.05(1000 - y) + 0.2y = 80
50 - 0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
x = 1000 - 200
x = 800

If a polygon is a square, then a polygon is a quadrilateral The truth value: The converse: The truth value: The inverse: The truth value: The contrapositive: The truth value:
Answer and Step-by-step explanation:
Given that if a polygon is a square, then a polygon is a quadrilateral, we find the converse, inverse and contrapositive of this implicational statement. The hypothesis is the causative statement and the conclusion is the resultant effect
The converse of this statement is the reverse of its statements hence:
If a polygon is a quadrilateral then a polygon is a square
The inverse of this statement is the negation of the statements hence :
If a polygon is not a square then a polygon is not a quadrilateral
The contrapositive of the statement is the interchange of the hypothesis and conclusion of the inverse statement hence:
If a polygon is not a quadrilateral then a polygon is not a square
what two numbers multiply to -36 and add up to 5
Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.
First, test if they multiply to -36:
9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

write the linear equation from the given information in slope intercept form passing through (-2,8) and perpendicular to y=2x+5
Answer:
y = [tex]-\frac{1}{2}[/tex] x + 9
Step-by-step explanation:
Given parameters:
Coordinates = (-2,8)
Equation of the line y = 2x + 5;
Unknown:
Linear equation of a line perpendicular = ?
Solution:
From the given expression, a line perpendicular will have a negative inverse of the slope given.
y = 2x + 5
Equation of a line is y = mx + c;
y and x are the coordinates
m is the slope
c is the intercepts
y = 2x + 5 ;
The slope is 2;
A line perpendicular will have a slope of [tex]-\frac{1}{2}[/tex]
Since y = 8 and x = -2, let us find c;
8 = 2 x [tex]-\frac{1}{2}[/tex] + c
8 = -1 + c
c = 8+1 = 9
The equation of the line is;
y = [tex]-\frac{1}{2}[/tex] x + 9
SLOPE HELP
hey, this just help if you're confused about slopes because I've seen a few questions about them I'll clear up a few things!
slope formula is y2-y1/x2-x1
memorize that and you'll be able to find your slope!
if you're given 2 points please label them (3,4) (0,6) labeling is this >>> (x1 3, y1, 4)
(x2 0, y2 6)
this makes it so it's organized and you know what you're subtracting
trust me I'll try to do it in my head and calculate it with a calculator then forget what points I used so WRITE IT DOWN! lol
if you hear parallel it's the same slope!
if you hear perpendicular it's the negative reciprocal example: 3/4x the perpendicular slope would be -4/3x
if you have a point and a slope and a line plugin the point to your line! let's say this one is parallel so the same slope
(3,4) y=3/4x + 2
4=3/4(3)+b
and solve for b!
anyways hopes this helps-
