Answer:

B 5

Step-by-step explanation:

Company A

total cost = 125+7h where h is the number of hours

Company B

total cost = 110 + 10h where h is the number of hours

125 + 7h < 110 + 10h

Subtract 7 h from each side

125 + 7h-7h<110+10h-7h

125 < 110+3h

Subtract 110 from each side

125-110< 110+3h

15 <3h

Divide by 3

15/3 <3h/3

5 <h

More than 5 hours

Answer:

6 hours

Step-by-step explanation:

A: y=125+7x

B: y=110+10x

for A to be a better deal than B, 125+7x<110+10x has to be true

subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3x
divide by 3: 5<x
so x has to be greater than 5, im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you

What type of information do you need to be given to prove two triangles are congruent?

marusya05 [52]

If the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle, the right triangles are congruent. The "included angle" in SAS is the angle formed by the two sides of the triangle being used. The "included side" in ASA is the side between the angles being used.

Complete the congruence statement for the figure shown. If the triangles cannot be shown congruent, type na in each blank.

Serjik [45]

Answer:

ΔABC≅ΔDEF by AAS (Angle-Angle-Side) Theorem

Step-by-step explanation:

We observe that $\angle A\cong\angle D$ , $\angle C\cong \angle F$ for the included angle, and $BC\cong EF$ for our side. Thus, the AAS Theorem proves that the triangles are congruent to each other
