Answer:
a. £2,500
b. £3,125
Step-by-step explanation:
The computation is shown below:
a. The original monthly expenditure is
Let us assume the original monthly expenditure be x
Monthly expenditure = x -15% of x
£2,125 = x - 0.15x
£2125 = 0.85x
x = £2125 ÷ 0.85
= £2,500
b. Now the monthy income is
Let us assume the monthly income be y
£2,500 = 80% of monthly income
£2,500 = 80% of y
y = £2,500 ÷ 80%
= £3,125
Set up the equation 120+20x=500. So x=19
Answer:
y = -7
Step-by-step explanation:
If x equals -14 then you would plug it in and the equation would be -2(-14)-3y=49
The new equation would be 28-3y=49
Then you would subtract 28 from both sides and get -3y=21
Lastly you would divide both sides by -3 and get y=-7
Answer:
60ft^2
Step-by-step explanation:
Use the area of a kite formula (A = pq / 2) where p is a diagonal and q is a diagonal.
The diagonal that is horizontal is 2 + 2 which is 4.
The diagonal that is vertical is 10 + 20 which is 30.
4 * 30 = 120
120 / 2 = 60
Answer: 12x
Step-by-step explanation: 3x times 4x = 12x
