Answer:
15
Step-by-step explanation:
Jackie would've washed 15 cars, since multiplying 2 x 5 = 10, so you'd have to multiply 3 by 5 to get the amount of cars Jackie washed if Michael washed 10.
Using decimal multipliers, it is found that the value of x is of 16.67.
<h3>What is a decimal multiplier?</h3>
Increases of a% or decreases of a% re represented by decimal values, as follows:
- The equivalent multiplier for an increase of a% is given by:

- The equivalent multiplier for an decrease of a% is given by:

In this problem:
- The price at the beginning of January was of a.
- Increase of 20% in January, hence
.
- Decrease of 20% in February, hence
.
- Increase of 25% in March, hence
.
- Decrease of x% in April, hence

The price of gasoline at the end of April was the same as it had been at the beginning of January, hence:






The value of x is of 16.67.

Answer:
9.75 pounds
Step-by-step explanation:
Because it takes 39 pounds to completely plant 4 acres, if you dived 39 by 4, you'll get the amount of seed you need per acre.
parallel lines have negative reciprocal slopes
so 1/2 becomes -2
point slope form
y-y1 =m(x-x1)
y-0 = -2(x--4)
y =-2(x+4)
y=-2x-8
The answer is A in my opinion
