solve for x if z = m - x

Answers

Answer:

x=m-z

Step-by-step explanation:

The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z

Find the product of -2*(-4)*9. Describe how you use the properties of
multiplication to find the product. Is the product positive or negative?

Answers

Answer:

72

Step-by-step explanation:

-2 x -4 = 8

8 x 9 = 72

Hope this helps! Please mark Brainliest!

Answer:

72 = Positive

Step-by-step explanation:

The property we use,

→ Associative property

Now the product will be,

→ (-2 × -4) × 9

→ 8 × 9 = 72

→ -2 × (-4 × 9)

→ -2 × (-36) = 72

Then the required sign is,

→ Positive (+ve)

Hence, the product is 72.

Jack plans to buy 2.25 lb of coleslaw at $2.80 per pound. He also wants 2lb of macaroni salad that sells for $3.15 per pound. Jack has a $10 bill in his wallet. Is this enough for the coleslaw and the macaroni? Explain.

Answers

No

2.25 times 2.80 gives the cost for the total coleslaw, which is $6.30
2 times 3.15 gives the cost for the total macaroni salad, which is also $6.30
Add those together and you get $12.60, which is larger than $10, so it is not enough
First, multiply 2.25 by 2.80 to get the cost of the coleslaw, which happens to be $6.30. Then, multiply 3.15 times 2, which would also get $6.30. Last, add $6.30 + $6.30, to get $12.60, which is more than $10, so he doesn’t have enough.

Use the diagram and the given angle measure to find the other three measures.

m∠1=143∘

m∠2=

m∠3=

m∠4=

Answers

Answer:

angle 2 = 37⁰

angle 3 = 153⁰

angle 4 = 37⁰

Step-by-step explanation:

I guess this refers to two intersecting lines which form 4 angles.

Angles 1 and 2 are supplementary angles whose sum is 180⁰.

Angle 1 + angle 2 = 180⁰

143⁰ + angle 2 = 180⁰

angle 2 = 180⁰ - 143⁰

angle 2 = 37⁰

Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.

Hope this helps...

Answer:

m∠1 = 143°

m∠2 = 37°

m∠3 = 143°

m∠4 = 37°

Answers

Answer:

The answer is below

Step-by-step explanation:

Let's work it out slowly

A)

$18.79 + $2.11 - $1.92 + $17.28

- 18.79 + 2.11 + 17.28 = 38.18

- 38.18 - 1.92 = 36.26

Ans = $36.26

B)

$7.45 + $24.45 + $74.17 + $76.52

- 7.45 + 24.45 = 31.9

- 74.17 + 76.52 = 150.69

- 150.69 + 31.9 = 182.59

Ans = $182.59

C) $98.45 - $10.63 + $2.82 - $20.26

- 98.45 - 10.63 - 20.26 = 67.56

- 67.56 + 2.82 = 70.38

Ans = $70.38

Hope you understand

The answer to A is $40.1
The answer to B is $-19.35
The answer to C is $70.38

Factorise (2x+3y)²-(x-4y)²​

Answers

Answer:

(3x−y)(x+7y)

Step-by-step explanation:

Factor (2x+3y)^2−(x−4y)^2

3x^2+20xy−7y^2

=(3x−y)(x+7y)

Answer:

(3x - y)(x + 7y)

Step-by-step explanation:

Given

(2x + 3y)² - (x - 4y)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = 2x + 3y and b = x - 4y , then

(2x + 3y + x - 4y)(2x + 3y - (x - 4y))

= (3x - y)(2x + 3y - x + 4y) = (3x - y)(x + 7y)

Thus

(2x + 3y)² - (x - 4y)² = (3x - y)(x + 7y) ← in factored form

Please help this fairly quick

Answers

Answer:

A) true

B) false

c) true

d) true

Step-by-step explanation:

A) angles 7 and 6 are vertical angles, which means they're equal.

so, A is True.

B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False

C) angle 7 is equal to angle 3, which is supplementary to angle 1.

so, 55 + angle 1 = 180

55 + angle1 = 180

subtract 55 from both sides of the equation

angle1 = 180 - 55

angle 1 = 125.

angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125

125 + 125 = 250

so, C is True

D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True

That becomes ([tex]x[/tex] x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.

Then you simplify it to 3[tex]x[/tex] = 12.

Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.
