Answer:
<h2>9 12/25.</h2>
Step-by-step explanation:
9.48 as a mixed number in simplest form:
<em><u>948/100</u></em>
<em><u>948/100= 948 ÷ 4/100 ÷ 4</u></em>
<em><u>948/100= 948 ÷ 4/100 ÷ 4= 237/25</u></em>
<em><u>948/100= 948 ÷ 4/100 ÷ 4= 237/25= 9 12/25</u></em>
<u>9 12/25 is the mixed number.</u>
Answer: 4
<u>Step-by-step explanation:</u>
Let P represent Pete's age today. Let C represent Claire's age today.
2 years ago: P - 2 = 3(C - 2) ⇒ P - 2 = 3C - 6 ⇒ P = 3C - 4
4 years ago: P - 4 = 4(C - 4) ⇒ P - 4 = 4C - 16 ⇒ P = 4C - 12
Use substitution to solve the system above:
3C - 4 = 4C - 12
- 4 = C - 12
8 = C
Plug in the C-value above into one of the equations to solve for P:
P = 3C - 4
= 3(8) - 4
= 24 - 4
= 20
So, Pete is 20 yrs old today and Claire is 8 years old today
When will Pete be twice as old as Claire?
20 + x = 2(8 + x)
20 + x = 16 + 2x
20 = 16 + x
4 = x
Their ages will have a 2:1 ratio in 4 years.
Answer:
<u>C</u>
Step-by-step explanation:
Evaluating the options :
<u>Option A</u>
⇒ 5/2x + 7/2 = 3/4x + 14
⇒ 2.5x - 0.75x = 14 - 3.5
⇒ 1.75x = 10.5
⇒ x = 6
⇒ No ×
===========================================================
<u>Option B</u>
⇒ 5/4x - 9 = 3/2x - 12
⇒ 1.5x - 1.25x = -9 + 12
⇒ 0.25x = 3
⇒ x = 12
⇒ No ×
=========================================================
<u>Option C</u>
⇒ 5/4x - 2 = 3/2x - 4
⇒ 1.5x - 1.25x = -2 + 4
⇒ 0.25x = 2
⇒ x = 8
⇒ Yes √
<u>C</u> is the right answer.
