3x+2y=11--------x1
7x-y=3------------x2

3x+2y=11---equ 1
14x-2y=6---equ 2

equ 1+ equ 2 will eliminate y
17x=17
x=1
then put x=1 in equ 1
3(1)+2y=11
2y=11-3
2y=8
y=8/2
y=4

One-quarter of the sum of 2 consecutive odd numbers is 14. Find the numbers.

aalyn [17]

Answer:

27 and 29

Step-by-step explanation:

let A and B the expected numbers

assuming B = A + 2, the problem can be written as follows

¼(A + A + 2) = 14

4*¼(A + A + 2) = 4*14

(A + A + 2) = 56

2A + 2 = 56

A + 1 = 28

A = 27

B = 27 + 2 = 29

Brian spends 3 5 of his wages on rent and 1 3 on food. If he makes £735 per week, how much money does he have left?

Margarita [4]

Answer :

Brian has $49 left.

Step by step explanation :

Step 1 : Find how much money Brian spends on rent and food.

First question we should be asking is what is 3/5 of 735?

Let's find that.

$\frac{3}{5}$ * $\frac{735}{1}$

= $\frac{(3)(735)}{(5)(1)}$

= $\frac{2205}{5}$

= 441

We know Brian spends $441 on rent. Now we find how much he spends on food.

$\frac{1}{3} * \frac{735}{1}$

= $\frac{(1)(735)}{(3)(1)}$

= $\frac{735}{3}$

= 245

Brian spends $245 on food.

Step 2 : Add what he spends on rent and food together.

$441 + $245 = $686

Step 3 : To find out how much money Brian has left, we subtract $686 from $735.

$735 - $686 = $49

Conclusion : Brian has $49 left.

Hope this helps, please mark brainliest if possible. Have a nice day.
