Answer 1

Answer:

y = -7

Step-by-step explanation:

5x+8y=29

5(17)+8y=29 (simplify by multiplying)

85+8y=29 (subtract 85 from both sides)

8y= -56 (divide both sides by 8y)

y = -7

The measure of ∠BCF is 60°, and the measure of ∠FCG is 35°. Which equation can you use to find the measure of ∠BCG? A. 60° + 35° = x B. 60° – 35° = x C. 60° + x = 35° D. 35° + x = 60° Part D The measure of ∠BCF is 60°, and the measure of ∠FCG is 35°. What is the measure of ∠BCG? Enter your answer in the box.

Answers

Answer:

60° + 35° = x

Step-by-step explanation:

The line CG is cutting the angle m<BCG to have m<BCF and m<FCG. Hence;

m<BCG = m<BCF + m<FCG

Given the following

∠BCF = 60°

∠FCG = 35°

Substitute

m<BCG = m<BCF + m<FCG

m<BCG = 60°+35°

hence the required expression is 60° + 35° = x where m<BCG is x

Answers

Answer:

acute angle

Step-by-step explanation:

acute angle because it is under 90°

If the angle measure is less than 90 degrees then it's acute, if it is equal to 90 degrees it's right or square, if it's more than 90 degrees it's obtuse, and if it's equal to 180 degrees it's a straight angle but in this case it's straight and obtuse since 180 is greater than 90.

ellie wanted to order candy online. company A us offering 2 1/2 pounds of chocolate for $32.50; while company B is offering 2 3/4 pounds of the same chocolate for $35.00. what is the unit price for company A? (please include units) what is the unit price for company B? which company is offering the lowest price per pound?

Answers

Answer:

Company A = $13

Company B = $12.73

Company B

Step-by-step explanation:

To determine the unit cost for each company, divide the price of chocolate by the number of pounds

Unit cost = price ÷ total pounds offered

Company A

$32.50 ÷ 2 1/2

$32.50 ÷ 5/2

$32.50 x 2/5 = $13

Company B

$35 ÷ 2 3/4

$35 ÷ 11/4

$35 X 4/11 = $12.73

$12.73 is less than $13. Company b has a lower price per pound

So looking at the larger main triangle...

the top angle is composed of two angles measuring 40° and 41°. So it is equal to 81°.

The angle on the lower left side is a supplimentary angle with the one that measures 110°. The two of them combined make a line. A straight line is 180°, so that angle is 70°. (180 - 110)

The final angle in the triangle is accross from x. This makes them a pair of vertical angles, so therefore congruent.

The angles of a triangle add up to 180°

We already know the other two angles so 180 - 81 - 70 = 11°

so x is also 11°
