I need a point to this question in order to answer it
Multiply 2x-2y=10 by 2,
4x-4y=20,
given:4x-5y=17
y=3
pluck it in
2x-6=10
move the 6 to the right
2x=16
divide
x=8
y=3
Answer:
Step-by-step explanation:
<u>Solve the inequality:</u>
- - a + 1/3 > 1/4
- a < 1/3 - 1/4
- a < 4/12 - 3/12
- a < 1/12
Correct choice is B
Answer:
Step-by-step explanation:
let, the length is z
thus the ratio will be 5z : 4z
perimeter = 2 (a + b)
360 = 2 ( 5z + 4z )
180 = 9z
z = 20 cm
length = 100 cm and width = 80cm
area = length * width
area = 100*80
area = 8000cm²
This is wrong.
It's supposed to be -4/15.
But try -4/5.
