Answer:
W = 12
L = 16
Step-by-step explanation:
Givens
L = L
W = 1/2 L + 4
Perimeter = 56
Formula
2L + 2W = Perimeter
Solution
Sustitute
2L + 2(1/2L + 4) = 56
2L + L + 8 = 56
3L + 8 = 56
3L + 8 - 8 = 56 - 8
3L = 48
3L/3 = 48/3
L = 16
W = 1/2 L + 4
W = 8 + 4
W = 12
Check
2L + 2W = 56
2*16 + 2*12 = 56
32 + 24 = 56
56 = 56 and it checks.
If four times the sum of a number and 5 is divided by 3, the result is 16. Step 1. Let x be the number.
Step 2. Four times the number and 5 is divided by 3
Step 3. The result is 16
Step 4. Multiply by 3 to both sides of equation to get rid of denominator
Step 5. Subtract 20 from both sides of equation
Step 6. Divide by 4 to both sides of equation
Step 7 ANSWER is x=7.
I hope the above steps were helpful.
Answer:
x = 5
Step-by-step explanation:
(7x + 16) = 90 - 39
7x + 16 = 51
7x = 51 - 16 = 35
x = 5
