Step-by-step explanation:
25% of 64 is 16. So find the two answers that are equivalent to 16.
A: 25*64 = 1600
16
B:
*64 = 16
C: 0.25 * 64 = 16
D: 64/
=256
16
E: 25/
= 39.06
16
Answer:
112
Step-by-step explanation:
- 4*7=28
- 28*12=336
- 336*(1/3)=112
If Car A's speed is x, then Car B's speed is x-22. Using the formula, we get that the distance is the same in both, so 4*(x-22)=D and 2.4*x=D due to that we plug 2.4 and 4 in for T and x-22 and x for R. Since they both equal D, we can write it as 2.4*x=4*(x-22). Using the distributive property, we get 4*(x-22)=4x-88=2.4*x. Subtracting 2.4*x from both sides as well as adding 88, we get 1.6*x=88. Dividing both sides by 1.6, we get 88/1.6=55= x=Car A's speed

$0.50/cm
Step-by-step explanation:
Answer:
y = -2x + 19
Step-by-step explanation:
Let the equation of the line is y = mx + b
Here, m = slope of the line
b = y - intercept
slope of a line passing through (x₁, y₁) and (x₂, y₂) is given by

slope of line passing through (2, 15) and (6, 7) will be

= (-2)
Equation of the line will be,
y = -2x + b
Since line passes through point (2, 15)
15 = -2 (2) + b
b = 15 + 4
b = 19
Therefore, equation will be,
y = -2x + 19
