-(7-9)z-6z=8(-6+2) solve for z
can I see the process I know the answer is 8 I just don't understand the process

Answers

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

Answer:

y = (2/3)x + 7

Step-by-step explanation:

Slope intercept form is y = mx +b

1) We start off with y =

2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x

3) b is y-intercept which = 7.

Put it all together: y = 2/3 x + 7

The answer is

y = 2/3x +7

George has just purchased a small rectangular fish tank that holds 837 milliliters of water. The tank has a width of 6.2 cm and a
height of 9 cm.
What is the length of the fish tank?

Answers

Answer:

Step-by-step explanation:

Answer:

15 cm

Step-by-step explanation:

Area = Length ⋅ Width ⋅ Height

let's set:

Area: 837

Length: X

Width: 6.2 cm

Height: 9cm

837 = X ⋅ 6.2 ⋅ 9

First multiply 6.2 and 9 to get 55.8

Next divide 837 by 55.8 and you get 15

therefore, the length (x) is equal to 15

angle A and angle B are supplementary angles. If m angle A = (2x + 26)° and m
angle B = (x + 25)°, then find the measure of angle B.


x=43

Answers

Answer:

m angle B = 68°

Step-by-step explanation:

Since they are supplementary, they add up to 180°

(2x+26) + (x+25) = 180

add like terms together

3x+26+25=180

simplify the left side

3x+51=180

subtract 51 from both sides

3x=129

divide both sides by 3

x=43

Then you plug in x into measure B

(43)+25

68

60% of 15 is what answer

Answers

The correct answer is 9. :)

Answer:9

Step-by-step explanation:

Think of it this way:

If 15=100%

then x= 60%

So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.

After collecting only three sharks teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.Part 1: Writing Expressions1. Write an expression that looks like Sarahs expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarahs expression but is not equivalent.2. Translate the new algebraic expression you created in Question 1 to a verbal expression. Part 2: Writing Equivalent Expressions3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.a. Use either the commutative property or combine like terms to create an equivalent expression.b. Use the distributive property to create an equivalent expression.4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression.
