Answer:

Choice C is correct.

Step-by-step explanation:

We have given an equation :

-5(a+3)=-55

We have to solve it for a.

-5(a+3)= -55

-5a-15= -55

Adding 15 on both sides of equation we get,

-5a =  -55+15

Multiplying 1/-5 on both sides we get,

-5a = -40

a = -40/ -5

a = 8 is the answer.

What is the value of the expression when x = 4?
Maurinko [17]

Answer:

The correct answer is Option 2. 48

Step-by-step explanation:

The given equation is  3x²  ---(1)

When we substitute the value of x we get the value of the equation.

Here it is given that,

x = 4

Substitute this value in the equation (1) we get,

3x²  = 3*(4)² = 3*16 = 48

Therefore the correct answer is Option 2. 48

I need to know the solution to this
Alex73 [517]
There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate

Look at equation 1, -2x+y=10 this can quite easily be manipulated to show y=10+2x.

Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one 4x-y=-14 \Rightarrow 4x-(10+2x)=-14 which can then be solved for x since there is only one variable 4x-10-2x=-14 \Rightarrow 2x=-4 \Rightarrow x=-2 and then with our x solution we can work out our y solution by using the equation we manipulated y=10+2x = 10+(2 \times -2) = 10-4=6.

So the solution to these equations is x=-2 when y=6
