3.6 (5 x 4) ÷ 3 + 5.0
use the PEMDAS rule
P - parentheses
E - exponents
M - multiplication
D - division
A - addition
S - subtraction
3.6 (5 x 4) ÷ 3 + 5.0
= 3.6 (20) ÷ 3 + 5.0
= 72 ÷ 3 + 5.0
= 24 + 5.0
=29
so the final answer would be 29!!
Answer:
Janine is 28. Ingrid is 30.
Step-by-step explanation:
Let the ages be x and x + 2 for Janine and her sister, respectively.
x/7 + (x + 2)/3 = 14
Multiply both sides by the LCD, 21, to get rid of denominators.
21 * x/7 + 21 * (x + 2)/2 = 21 * 14
3x + 7(x + 2) = 294
3x + 7x + 14 = 294
10x = 280
x = 28
x + 2 = 30
Answer: Janine is 28. Ingrid is 30.
