4v=(-7)+3v.

4v=−7+3v

Step 1: Simplify both sides of the equation.

4v=3v−7

Step 2: Subtract 3v from both sides.

4v−3v=3v−7−3v

v=−7

I hope this helps!

Find the midpoint of side EF. (4 points)

umka2103 [35]

Answer:

Midpoint of side EF would be (-.5,4.5)

Step-by-step explanation:

We know that the coordinates of a mid-point C(e,f) of a line segment AB with vertices A(a,b) and B(c,d) is given by:

e=a+c/2,f=b+d/2

Here we have to find the mid-point of side EF.

E(-2,3) i.e. (a,b)=(2,3)

and F(1,6) i.e. (c,d)=(1,6)

Hence, the coordinate of midpoint of EF is:

e=-2+1/2, f=3+6/2

e=-1/2, f=9/2

e=.5, f=4.5

SO, the mid-point would be (-0.5,4.5)

She’ll need 18 eggs.

2 eggs = 12 (dozen) muffins

108 muffins (needed) / 12 muffins

= 9 groups of 12 muffins

so therefore 2eggs x 9 groups of muffins = 18 eggs

1. Rewrite the expression. Use an exponent, rather than repeated multiplication. (–4)(–4)

AlekseyPX

-4^2 is the same as -4*-4

-4*-4=16

-4^2= 16

-4^2 is the exponent.

Find two numbers whose sum is 55 and whose product is 646

Svet_ta [14]

Answer:

17 and 38

Step-by-step explanation:

x + y = 55......x = 55 - y

x * y = 646

y(55 - y) = 646

55y - y^2 = 646

y^2 - 55y + 646 = 0

(y - 17)(y - 38) = 0

y - 17 = 0 y - 38 = 0

y = 17 y = 38

ur numbers are 17 and 38
