In your own words, explain why solving 4=2x uses the Division Property of Equality. Provide an example with your explanation.
balandron [24]
Solving 4=2x is using the division property because in order to get the last portion of that answer u have to divide both sides by 2x to get x by itself
For example
4=2x to get x by itself you have to divide both sides by 2x
And your final answer would be
x is equal to 2 (x=2)

Can you please answer this
jasenka [17]

Answer:

Sum angle of triangle BHD = 180°

36 + 39 + BHD = 180

BHD = 180 - 36 - 39

= 105°

BHD + x° = 180° (straight angle)

105° + x° = 180°

x = 180 - 105

= 75°

A 2018 Chevrolet Suburban averages 15 miles per gallon of gas in the city. It drives 47% farther per gallon of gas on the highwa
solmaris [256]

Answer:

On the highway, the cost to drive per mile is $2.21

Step-by-step explanation:

In the city the average distance per gallon is 15 miles

On the highway, he can drive 47% farther;

The distance he can cover on the highway per gallon will be;

15 + 47% of 15

= 15 + 0.47(15)

= 15 + 7.05 = 22.05

So on the highway, he can travel a distance of 22.05 miles

So the cost per mile on the highway would be;

$3.25 for 15 miles

$x for 22.05 miles

so we have the cost to drive per mile on the highway as;

(3.25 * 15)/22.05 = $2.21

Find the unknown angles
Shtirlitz [24]

Answer:

Step-by-step explanation:

∠WZA + WZY = 180     {linear pair}

88 + ∠WZY = 180

∠WZY = 180 - 88

∠WZY = 92°

∠WXY + ∠WZY = 180     {Opposite angle in cyclic quadrilateral}

x + 92 = 180

       x = 180 - 92

x = 88°
