Step 1:
Write what you know
Madeline's Height: 6 ft
Madeline's Shadow: 108 in
Friend's Height: X (we use X as a variable because his height is unknown)
Friend's Shadow: 108 in - 1.5 ft
108 in - 18 in
90 in
Step 2:
Set up proportions
6 x
----- = -----
108 90
Step 3:
Cross Multiply & Solve
108x = 540
x = 5 ft tall
Answer:
B
Step-by-step explanation:
Simplify the variables, everything with the same variable gets combined. -3x+15x you take the symbol in front of both the numbers, so it would be -3+15 which is 12. then you put them together 12x-9, because the negative is in front of the 9. don’t forget your variables
Step-by-step explanation:
First, set up your problem:
(1) a = 7b from “Aaron has 7 times as many sheep as Beth”
(2) a + b = 608 from “both together had 608”
We can choose either equation to start with and solve for one of the two variables. Starting with equation (2), add =b to both sides:
a + b = b = 608 - b
So a = 608 - b
Substitute back into equation (1) replacing a with 608 - b:
608–b = 7b
Now we solve for b. First add b to both sides:
608 - b + b = 7b + b
Therefore:
608 = 8b
Divide both sides by 8 to get:
b = 608/8 = 76
Now substitute back into equation (1):
a = 7 * 76 = 532
So the final answer is
a = 532, Aaron had 532 sheep
b = 76, Beth had 76 sheep
