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

Janine and her older sister Ingrid's ages are consecutive even numbers. When Janine's age is divided by seven, and Ingrid's age
a_sh-v [17]

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.
