Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x

Answers

Answer:

Only A, the first equation is true.

Step-by-step explanation:

A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true

B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

Step-by-step explanation:

Answer:

Step-by-step explanation:

% means out of 100, so 80% is 80/100

Let's divide 100/80 to find a scale we can use to multiply 36, 100/80 =

36 times 1.25 = 45

There's 45 donuts

Double check:

45(80/100) = 36, we're right

What can you conclude from the diagram

Answers

Answer:

You can conclude from the diagram that m∠P is less than m∠N ⇒ A

Step-by-step explanation:

In any triangle, you can arrange the lengths of the sides according to the measure of the opposite anglesIn any triangle, you can arrange the measure of the angles according to the lengths of the opposite sides

Example:

In ΔABC, if the arrangement of the sides is AB < BC < CA, then the arrangement of the measures of the angles is m∠C < m∠A < m∠B

Let us use this fact to solve the question

→ In ΔKNP

∵ KP = 8 units

∵ KN = 6 units

∵ 6 < 8

∴ KN < KP

∵ ∠P is opposite to the side KN

∵ ∠N is opposite to the side KP

∵ KN < KP

→ By using the fact above

∴ m∠P < m∠N

∴ m∠P is less than m∠N

∴ You can conclude from the diagram that m∠P is less than m∠N

The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?

Answers

Answer:

The total cost of the shopping trip is:

$82.08

Step-by-step explanation:

The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?

Step 1

We find the price after the discount

The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off

Hence:

20% × $95

= $19

Therefore: $95 - $19

= $76

Step 2

We find the amount of sales tax

The sales tax is 8%

Hence:

8% of $76

= $6.08

Our sales tax = $6.08

Step 3

The total cost of the shopping trip is calculated as:

$76 + sales tax

= $76 + $6.08

= $82.08

y = 8/3 - 17/3 = -9/3 = -3

Swim floats are on sale at sam’s shop. They are marked 30% off of the original price of 18.00. How much will the float cost

Answers

Answer:

the cost is now $5.40

Step-by-step explanation:

if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.

we multiply if we are trying to find the new amount and we divide to find the old amount.

Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12

Answers

Answer:

x = 5

Step-by-step explanation:

Given

3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side

3x - 5x + 25 = 2x + 5

- 2x + 25 = 2x + 5 ( subtract 2x from both sides )

- 4x + 25 = 5 ( subtract 25 from both sides )

- 4x = - 20 ( divide both sides by - 4 )

x = 5
