Answer:

Addition property of equality

Step-by-step explanation:

Given:

2x+2y=14 \ -x+y = 5

We need to find the missing reason in the proof.

Solution:

By solving the above equation we get;

2x+2y=14 \ -x+y = 5 ⇒ Given:

Now by adding both side by 'x' we get;

2x+2y=14 \ -x+y+x = 5+x

2x+2y=14 \ y = x+5  ⇒ Addition property of equality

Hence The missing reason in the proof was Addition Property of equality.

Find missing measure (No.6)
aalyn [17]

Answer:

Step-by-step explanation:

6 no

1.angle 2=92 degree(being vertically opposite angle)

2.angle 1+33+92=180(sum of interior angles of a triangle)

angle 1+125=180

angle 1=180-125

angle 1=55

3.angle 3+angle 2+115+90=360(sum of four angles is always 360 degree)

angle 3+92+205=360

angle 3+297=360

angle 3=360-297

angle 3=63

You require space to serve 65 vehicles at any one time. Will a facility measuring 145ft by 130ft be adequate if each vehicle req
Hunter-Best [27]

Answer: No, it is not sufficient to serve 65 vehicles as it can only serve 62 vehicles with this space

Step-by-step explanation:

Since we have given that

Dimensions of space where vehicles are stored is

145 feet by 130 feet

Number of vehicles to serve = 65

Area required for each vehicle = 300 ft²

So, we need to find that is it sufficient for to serve 65 vehicles.

So, first we find the number of vehicles can be served in this space

\text{ Number of vehicles}=\frac{\text{ Area of space}}{\text Area of space required for one vehicle }}\\\\=\frac{145\times 130}{300}\\\\=\frac{18850}{300}\\\\=62.83\\\\=62\ approx

No, it is not sufficient to serve 65 vehicles as it can only serve 62 vehicles with this space.

How do i reflect something on a grid?
Xelga [282]

Answer:

Think of reflect as looking in a mirror. The question should tell you how your reflecting. It might say "reflect the rectangle over the y axis"  (Look at the attachment below to see example).

Step-by-step explanation:

I can help more if I see the question. But usually questions ask you to reflect over the y or x axis.
