Answer:
x = 12.5
Step-by-step explanation:
The phrase "Twice the number of x" = 2x
2x = 25 ⇒ Divide both sides by 2
2x ÷ 2 = 25 ÷ 2
x = 12.5

Find the slope of the line that passes through (1, 13) and (10, 6).
Answer:
-7/9
Step-by-step explanation:
Using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 6-13)/(10-1)
= -7/9
3m^2 + 5n; if m = -4 and n = -13
Answer:
3m^2 + 5n = 3

A car is 200 inches long. A truck is 50% longer than the car. How long is the truck?
If a truck is 50% longer than the car, then its 1.5x.
200 * 1.5
= 300
So the truck is 300 inches
*50% of 200 is 100.
100+200=300* would be your answer.

7 x 13 = 91
12 x 13 = 156
so u divide 143 by 13 and u get 11
Answer:
B
Step-by-step explanation:
The answer is B because you have to figure out how many $ he gets from mowing 1 yard which is found by dividing the number of money to the number of yard he mowed for one of the weeks it doesn't matter which one.The answer to how much he gets for 1 yard is 13 dollars so the last step is the divide 143 by 13

A = lw
A = 9
9 = lw
9 = (x + 2)(x + 3)
9 = x² + 3x + 2x + 6
9 = x² + 5x + 6
x² + 5x = 3
Answer:
A = lw
A = 9
9 = lw
9 = (x + 2)(x + 3)
9 = x² + 3x + 2x + 6
9 = x² + 5x + 6
x² + 5x = 3

If car number plates have 3 English alphabet letters followed by 3 digits, how many of these start with ABC?
Answer:
351520000
Step-by-step explanation:
351520000
Explanation:
There are 10 possible digits for the numbers (0,1,2,...,9), and 26 possible letters (A,B,C,.....,Z).
Since repetitions are allowed, we have that for each letter used, 26 still remain for the next choice, and for each digit used, 10 still remain for the next choice.
Hence, by the multiplication principle, the total different number of letter permutations is
26
×
26
×
26
=
17576
and the total number of digit permutations is
10
×
10

=

But now since they can be in any order, we basically require in how many different ways can 3 be chosen from 6 which is the combination
6

So for each of the original permutations of numbers and letters, we must consider the 20 different combinations of positions they can be in.
Therefore by the multiplication principle, the total possible different number plates is

How do I solve this?
Answer:
100 miles.
Step-by-step explanation:
The combined speed of the 2 trains = 38 + 42 = 80 mph.
The time taken before they crossed = 15:35 - 14:20
= 1:15 = 1.25 hours
Speed = distance / time, so
80 = distance / 1.25
Distance = 80 * 1.25
100 miles.
Answer:
100 miles
Step-by-step explanation:
A -----------P------------------ B
tom start at 14:20 with speed of 38mph
ben with speed 42mph
meeting time is 15:35
time difference is 75 min = 75/60 = 1.25 hours
distance travelled by tom is AP
AP = v * t
= 38 * 1.25
= 47.5 miles
distance travelled by ben is BP
BP = v * t
= 42 * 1.25
= 52.5 miles
distance between two cities is AB = AP + PB
= 47.5 + 52.5
= 100 miles

4. Michelle walked 98,094 steps this week. Her best friend Nadia, walked 15,947 steps more than Michelle. How many steps did Nadia walk this week? Show how you solved this problem.
Answer: 114,041 steps
Step-by-step explanation:
No. of steps by Michelle = 98,094
No. of steps by Nadia = 15,947 + Michelle's steps
= 15,947 + 98,094
Nadia's steps = 114,041
Write an equation in point-slope then convert into slope intercept for a line that passes through (3,-2) with a slope of -2
Answer:
Point-slope form: [tex]y+2=-2x+6[/tex]
Slope intercept form: [tex]y=-2x+4[/tex]
Step-by-step explanation:
[tex]y - y_{1} = m * (x - x_{1})[/tex]
[tex]y-(-2)=-2*(x-3)\\y+2=-2x+6\\y=-2x+4[/tex]

Sean bought 1.8 pounds of gummy bears and 0.6 pounds of jelly beans and paid $10.26. He went back to the store the following week and bought 1.2 pounds of gummy bears and 1.5 pounds of jelly beans and paid $15.09. What is the price per pound of each type of candy?
Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)

Use the graph to answer the following…
Answer:
slope = 2 because it goes up by 2 and across 1
10 = 2(1)+b
10=2+b
-2 -2
b = 8
y intercept = 8
equation: y = 2x+8
yes it is proportional because it has a constant rate of change or slope
the baker family goes out for supper and the price of the meal is $58. the sales tax on the meal is 6.5% and the family leaves a 20% tip on the pre- tax amount. what is the total cost of the meal?
Answer:
$73.37 is the new price.
Step-by-step explanation:
0.065 x 58 = 3.77
0.2 x 58 = 11.6
3.77 + 11.6 = 15.37
15.37 + 58 = 73.37
