So we know that:
3(-8 + 4v) = 8v
To find v, first simplify the left hand side:
-24 + 12v = 8v
Then group the "v's" over to the right:
-24 = -4v
-6 = -v
So v = 6
Hope this helped
Answer:
Step-by-step explanation:
29 5x+8+x+4=90
6x=78
x=13
30 3x-7+11x-1=90
14x=98
x=7
31 3x+x+8=180
4x=172
x=43
32 6x-1+5x-17=180
11x=198
x=18
the area of the surface of this design is 31 in long
Estimation:
23 --> rounded to 20
71 --> rounded to 70
70 + 20 = 90. I rounded both numbers down so the exact sum must be only a little greater than my estimate.
Answer:
Charles need
more ounces of seeds.
Step-by-step explanation:
Given that:
Quantity of seeds Charles has =
=
ounces
Quantity of seeds Charles need =
ounces
Let,
x be the number of remaining seeds Charles need.
x = Seeds needed - Seeds Charles already have
x = 
x = 
x = 
x = 
x =
ounces
Hence,
Charles need
more ounces of seeds.
