Answer:
15x + 3y = 10.
Step-by-step explanation:
you have to solve for y.
isolate the variable.
15x + 3y = 10
start by subtracting 15x on both sides.
3y = -15x +10
then divide both sides by 3
y = -15/3x + 10/3
simplify.
y = -5x + 10/3
10/3 can be written as 3.33
or 3 and 1/3
Answer:
12
Step-by-step explanation:
2/3 x + x = 20
2/3 x + 3/3x = 20
5/3 x = 20 ... times 3/5 both sides
x = 12
check: 2/3 x 12 + 12 = 8 + 12 = 20
Answer:
72.2 square meter
Step-by-step explanation:
(3.8)(3.8)= 14.44
(14.44)(5)=72.2
The equation would be ' y = 1/2x'

200 is 80%
200 / 80 = 2.50 (1%)
2.50 * 100 = £250
Hope this helps.
