4 x 0.90 = £3.60
£13.50 - £3.60 = £9.90
0.9 + 0.75 = £1.65
£9.90/£1.65 = 6

Let x and y be the two unknown numbers. If one number, say x,is 5 more than 3 times another, say y, the equation would be
x = 5 + 3y
When their difference is 35, x-y = 35, since x is the much larger number here. We substitute x to solve for the smaller number, y.
x - y = 35
(5 + 3y) -y = 35
5 +2y = 35
2y = 35-5
2y = 30
y = 15
The larger number x would be
x = 5 + 3(15)
x = 50
The answer is 50.
Answer:
A
0.1 is -1/10 which is obviously less than -1/7 .
Else we can also know by multiplying by 100
-1/10 *100 = -10
-1/7 *100 = -14.444
Answer:
-5/3
Step-by-step explanation:
Answer: x=0.5, y=1
Step-by-step explanation:
-4x+3y=1
6x-y=2
6x-2=y
-4x+3(6x-2)=1
-4x+18x-6=1
-4x+18x=7
14x=7
x=0.5
6x-y=2
6(0.5)-y=2
3-y=2
y=1
