Y = -5x + 9
y = 5x + 7
5x + 7 = -5x + 9
5x + 5x = 9 - 7
10x = 2
x = 2/10 reduces to 1/5
y = 5x + 7
y = 5(1/5) + 7
y = 1 + 7
y = 8
solution is (1/5,8)
Answer:
123.8 cm
Step-by-step explanation:
well we know that STUV is a parallelogram (given)
so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)
so we have that
VU=TS
and we know that VU=123.8 cm (given)
so TS=123.8
I Am not sure but the answer is 104
Answer:
x = 20
Step-by-step explanation:
The goal is to move the x's and the whole numbers to their own sides of the equation. When moving pieces to opposite sides, the signs change (a negative becomes a positive, for example).
3x - 4 = 2(x + 8)
First we're going to use distributive property to remove the brackets in
2(x + 8)
This becomes 2x + 16
3x - 4 = 2x + 16
Moving 2x over...
3x - 2x - 4 = 16
Moving -4 over...
3x - 2x = 16 + 4
Collecting like terms...
x = 20
Answer:
Step-by-step explanation:
Let the number is x.
<u>Use the following equation to find x:</u>
- 3/8x - 1 = 5
- 3/8x = 6
- x = 6*8/3
- x = 16
