Answer:
51 and 42
Step-by-step explanation:
Use
x + y = 93
x - y = 9
Add those two equations together and you get 2x = 102
*y is not in the equation anymore because y + -y = 0*
Divide both sides by 2
x = 51
plug x into one of the equations; let's use x + y = 93
Then you get, 51 + y = 93
Subtract both sides by 51 and you get y = 42
Plug both in the other equation to make sure the numbers work.
51 + 42 = 93; true
51 - 42 = 9; true
Answer: 6x^2 - 23x + 20
Step-by-step explanation:
To find the area of a rectangle you multiple length times width.
(3x-4)(2x-5)
Use foil to distribute the terms:
6x^2 -15x-8x+20
combine like terms
6x^2 - 23x + 20
I do not see a list of options so I can not tell you what letter answer this lines up with but this is the answer.
Answer:
what do we have to do
Step-by-step explanation:
Answer:
v=18
Step-by-step explanation:
26=8+v
<em>Swap sides:</em>
8+v=26
<em>Subtract 8 from both sides:</em>
8+v-8=26-8
<em>Group like terms:</em>
v+8-8=26-8
<em>Simplify the arithmetic:</em>
v=26-8
v=18
