Answer:
First collect like terms on one side
150-2-120=2x+x+2x
148-120=3x+2x
28=5x
Let me change the positions so it could be easier to solve
5x=28
x=28/5
x=5.6
Step-by-step explanation:
I hope I explained well, please give me brainliest
Answer:
x = 31
Step-by-step explanation:
AC=BD
3x+7 = 131-x
Subtract 7 from both sides
3x = 124-x
Add x to 3x
4x = 124
Divide by 4
x = 31
Check:
3(31)+7 = 131 - 31
Mulitply 3 times 31 / subtract 131 and 31
93+7 = 100
Add 93 to 7
100 = 100
Answer:90%
Step-by-step explanation:
18/20=0.9
Percentage means the tenth place so it has to be 90%
Answer:
either 5 or 11
Step-by-step explanation:
(8, -12)
(5, -9) or (11, -9)
If y varies consistently with x then it would copy what happens, in a manner of speaking.
In this case, y increases by three, x would either add 3 or subtract 3
I am not completely sure on this.
