Answer:
R + 5b = 300
Step-by-step explanation:
Rogers steps include a scale holding five bricks of equal weight and the scale reads 300 pounds.
We want to write an equation relating Rogers weight and the weight of the bricks to the total weight of the bricks to the total weight shown on the scale.
We have been told to use R for Rogers weight and b for the weight of a single brick.
Since Rogers is holding 5 bricks, the weight of 5 bricks will be 5b.
The sum of Rogers weight and the five bricks is equal to 300 pounds.
Therefore, the equation relating them is:
R + 5b = 300
Answer:
The answer is 160. There are 160 boys in the school. Take 360 divide by 9, then multiply by four.
Step-by-step explanation:
Y = 11.5x + 22
y = -13x + 218
when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks
11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===
