Answer:
The equation is: <em>y</em> = 15·<em>x</em>
Step-by-step explanation:
It is provided that at the Speedy Bike Works, 15 bicycles are produced each hour.
Consider the table below.
Number of Hours: 1 3 6 10
Number of Bicycles Produced: 15 45 90 150
Compute the ratio of number of bicycles produced and number of hours for every data above as follows:

The ratio of the number of bicycles produced and number of hours is same for every data value.
Thus, the relationship between the number of bicycles produced and number of hours is proportional.
The equation for the relationship is:
<em>y</em> = 15·<em>x</em>
<em>y</em> = number of bicycles produced
<em>x</em> = number of hours
Answer:
Polly=30
Andy=60
Phoebe=180
Step-by-step explanation:
Polly=x
Andy=2x
Phoeby 3(2x)=6x
x+2x+6x=270
9x=270
x=30
Polly=x=30
Andy = 2x=60
Phoebe=6x=180
Blue paint - 2/1/2 = 1 gallon
White paint - 1/2 gallon
1 wall - 1/4 quart of paint
As 1 quart = 1/4 gallon, one gallon of paint is enough to cover 16 walls.
the walls can be either white or blue and the leftover will be 1 and 1/4 gallon paint.
For question 40 the answer is B
The answer is -4 because two negatives is the same as adding so -6 + 2 = -4
