Answer:
y=1 (sorry i dont know what justify means lol, i forgot) i know how to solve the answer lol.
Step-by-step explanation:
10y-15-4y=8-2y-15
10y-4y+2y=8-15+15
8y=8
y=1
Answer:
7 and 13
Step-by-step explanation:
let the 2 numbers be x and y , x > y , then
x = y + 6 → (1)
(x + y) = y - 2 ( multiply both sides by 4 to clear the fraction )
x + y = 4y - 8 ( subtract 4y from both sides )
x - 3y = - 8 → (2)
Substitute x = y + 6 into (2)
y + 6 - 3y = - 8
- 2y + 6 = - 8 ( subtract 6 from both sides )
- 2y = - 14 ( divide both sides by - 2 )
y = 7
Substitute y = 7 into (1)
x = 7 + 6 = 13
The 2 numbers are 7 and 13
Y=4 when X=1
So it mean y=4(1)
Y=4
X equal 1 when they don't give you the number
Answer:
Just count and find the area of the units shown below,
6 x 2 = 12, 12 divided by 2 = 6
6 x 2(two of the triangles) = 12
7 x 3 = 21
21 x 2 = 42
7 x 6 = 42
Add all given areas:
12 + 42 + 42 = 96 is your answer
