Solve for m.

Add 7 to both sides to get 3m=15

Then divide by sides by 3 to get m=5.

The final answer is m=5.

1.) add 7 to both sides

3m = 8 + 7

2.) add 8+7

3m = 15

3.) divide both sides by 3

m = 15/3

4.) divide 15/3

5.) m = 5

Which of the following theorems verified that angle xyz is congruent too angle uwv?

icang [17]

Answer:

Option B. AA

Step-by-step explanation:

we know that

Angle-Angle (AA) Similarity Postulate, states that If two angles of one triangle are congruent to two angles of another, then the triangles must be similar

In this problem

<em>In the triangle XYZ</em>

∠X=70°

∠Y=90°

∠Z=90°-70°=20° (remember that angle X and angle Z are complementary)

<em>In the triangle UWV</em>

∠V=20°

∠W=90°

∠U=90°-20°=70° (remember that angle V and angle U are complementary)

therefore

Traingles XYZ and UWV are similar by AA Similarity Postulate

Use a = -2, b = - 3, and c = 6 to write an expression that has a value of 12.

Semenov [28]

a negative times a negative = a positive

so (a * b) + c = 12

(-2 * -3) +6 = 12

6+6 = 12

If a car with an average speed of 40 miles per hour drives for 45 minutes how far will it have gone

REY [17]

Answer: $30\ miles$

Step-by-step explanation:

The average speed of the car is 40 miles per hour:

$V=40\ \frac{mi}{h}$

The car drives for 45 minutes:

$t=45\ min$

Since 1 hours has 60 minutes, we can convert the time from minutes to hours:

$(45\ min)(\frac{1\ h}{60\ min})=0.75\ h$

Knowing these values, we can use the following formula for calculate the distace "d":

$d=V*t$

Therefore, substituting values into the formula, we get:

$d=(40\ \frac{mi}{h})(0.75\ h)\\\\d=30\ mi$

7. Isosceles triangle ABC is shown below with legs that measure 8 inches and a vertex angle of 50D. (a) Determine the area of AB

Flura [38]

Answer:

<h2>The area of the triangle ABC is 32 square inches.</h2>

Step-by-step explanation:

We know that the given triangle is a right-isosceles triangle, which means its leg are equal.

The area of a triangle is defined as

$A=\frac{1}{2}bh$

Where $b=8$ and $h=8$ . Replacing values, we have

$A=\frac{1}{2} \times 8 \times 8 = 32 \ in^{2}$

Therefore, the area of the triangle ABC is 32 square inches.
