Can you Find the value of x I don’t know the answer

Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

x+4−3x=3x−6−3x

−2x+4=−6

Step 2: Subtract 4 from both sides.

−2x+4−4=−6−4

−2x=−10

Step 3: Divide both sides by -2.

−2x /−2 = −10 /−2

x = 5

Complete the pairs of corresponding parts if △RST ≅ △TXY.

∠STR =
∠ XYT
∠ TXY
∠ XTY

Answers

Answer:

∠STR is associated with ∠ XYT

Therefore, we conclude that:

∠STR = ∠ XYT

Step-by-step explanation:

Given

△RST ≅ △TXY

To determine:

∠STR = ?

△RST ≅ △TXY

So the triangles △RST and △TXY are congruent to each other.

We know that congruent triangles have equal corresponding parts.

Please check the attached graph.

From the graph, it is clear that:

∠STR is associated with ∠ XYT

∠STR = ∠ XYT

Therefore, we conclude that:

∠STR = ∠ XYT

What is the surface area of a rectangular prism with measurements of 5, 7, and 4?

Answers

Answer:

166

Step-by-step explanation:

A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

A=2(wl+hl+hw)=2·(7·5+4·5+4·7)=166

A = 166

Answers

Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.

Answer:

Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches

11 = 7 + 4x is what is what is what

Answers

Answer:

x = 1

Step-by-step explanation:

11 = 7 + 4x

Subtract 7 from both sides

11-7 = 7-7 + 4x

4 = 4x

Divide 4 from both sides

4/4 = 4x/4

1 = x

x = 1

Check:

11 = 7 +4(1)

11 = 7+4

11 = 11

The soccer team is planning to sell health bars for a fundraiser. The prices of purchasing health bars from two different companies are represented by the system of equations shown, where x is the number of bars purchased and y is the total cost in dollars. Company A: y=0.75x Company B: y=10+0.50x How many bars would the team need to purchase from each company in order for the total cost to be equal?

Answers

Answer:

40 bars

Step-by-step explanation:

Where x = Number of bars purchased by each team

We solve this question by equating both Equations from Company A to Company B

Company A = Company B

0.75x = 10 + 0.50x

Collect like terms

0.75x - 0.50x = 10

0.25x = 10

x = 10/0.25

x = 40 bars

Hence, each team need to purchase 40 bars from each company
