Solve for f. 2+1.25f=10-2.75f2+1.25f=10−2.75f

Ne4ueva [31]

We have to solve for f:
2 + 1.25 f = 10 - 2.75 f
1.25 f + 2.75 f = 10 + 2
4 f = 12
f = 12 : 4
f = 3
Answer: f = 3

Am I correct on number 3? If not whats the correct answer? And what is the answer for number 4? Will be marking brainliest!!

timama [110]

Answer for number 4 is $\frac{\bold2}{\bold3}$ hour.

Step-by-step explanation:

Maximum hour spent for all homework (English homework + math homework) is 2 hours.

Let us assume the hours spent for English homework be 'e'.

It is given that:

(Hours spent for math homework) = 2 × (Hours spent for English homework)

Hours spent for math homework = 2 × e = 2e

Total hours spent = (Hours spent for math homework) + (Hours spent for English homework)

Total hours spent = 2e + e = 3e

2 = 3e

3e = 2

∴ e = $\frac{\bold2}{\bold3}$

Therefore number of hours spent on English homework is equal to $\frac{\bold2}{\bold3}$ hours.
