Answer:
hello : 6.23x10^14 > 8.912x10^12^12
Step-by-step explanation:
let : A= 6.23x10^14 and B = 8.912x10^12
A= (6.23x10^2) x10^12 ... because : 10^14 = 10^2x10^12
A = 623 x 10^12
623 > 8.912
so : A > B

Answer:
- Sara is 10 and Laila is 8
Step-by-step explanation:
- Sara's age = s
- Laila's age = l
<u>The ratios:</u>
- (s + 2)/(l + 2) = 6/5 ⇒ 5(s + 2) = 6(l + 2) ⇒ 5s = 6l + 2
<u>Substitute s into the second equation and solve for l:</u>
- 5(5l/4) = 6l + 2
- 25l = 24l + 8
- l = 8
<u>Fins s:</u>
