Answer: 10x + 7
Step-by-step explanation:
multiply everything
2x + 7x + x + 7
combine like terms
10x + 7
4 × v + 1 - (4 - 7) < 0
4(v) + 1
Divide (÷) each side side '4'
Then subtract (-) 1 from each side
v < -1
Now we're looking for then inequality plot in: 4.000v + 4.000 < 0
Therefore, your answer would have to be
" x < -1" (:
Answer: 1300
Step-by-step explanation:
13*10 = 130*10=1300
Answer:
y=1 , z=-2
Step-by-step explanation:
I will use the method of elimination :
Multiply the top equation by 5 to make equation 3 :
35z + 15y = -55
Multiply bottom equation by 3 to make equation 4:
6z + 15y = 3
Subtract equation 3 from equation 4 to eliminate the y :
-29z = 58
Divide both sides by -29 to solve for z :
z = 58 ÷ -29
z = -2
Substitute this value into either equation 1 or 2 to solve for y :
I chose equation 2 :
2(-2) + 5y = 1
-4 + 5y = 1
Add 4 to both sides :
5y = 5
Divide both sides by 5 :
y = 1
Hope this helped and have a good day
