First thing to do is solve the given equation for v
-11v-7 = 4
-11v = 4+7
-11v = 11
v = 11/(-11)
v = -1
Once we know this, we can use it to compute the following
7v-10 = 7*(-1) - 10 = -7 - 10 = -17

Answer: -17
Answer:
123
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
because of the kind of angle it is, the two equations are equal. So, put the equations equal to each other and solve:
x+35=3x+1
combine like terms (by subtracting)
2x=34
isolate x by dividing by 2
x=17

Answer:
384 cm
Step-by-step explanation:
7.5 x 24 = 180
8.5 + 7.5 = 16
16 x 24 = 384
Area=length*width
let the sides perpendicular to the river be x
then the side parallel to the river is 4,700-2x
A(x)=x(4700-2x)
A(x)=4700x-2x^2
This a quadratic function with a=-2 and b=4700
thus
Maximum area occurs where x=-b/2a=-4700(-2*2)=1,175 ft
length=4700-2(1175)=2,350 ft
