The answer is subtract two from both sides. Explanation: because it males the equation even and easier to solve.

Answer:

[tex] \underline{ \underline{ \boxed{ \text{Subtract \: 2 \: from \: both \: sides}}}}[/tex]

Step-by-step explanation:

Since we want constants only on the right hand side , we have to remove 2 which is on the left hand side. The opposite of +2 is -2 and whatever we do to one side , we must do to the other side. So, The first step that would be used to solve the equation should be Subtract 2 from both sides.

Which ratio is greater, 4:5 or 3:4?

Answers

4:5
explanation-

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.

Answer:

4:5

82

Answers

11 1/8
Explanation
The answer comes out to 11.125 however in mixed number form it’s 11 1/8

Answer:

11 and 1/8

Step-by-step explanation:

We can do this in the format of PEMDAS

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

10 + (2 × 3[tex])^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]

Let's do the parenthesis first

10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]

Now we can do the fraction with the exponent second

10 + [tex]6^{2}[/tex] ÷ 4 ×  [tex]\frac{1}{8}[/tex]

Now we can do the other exponent

10 + 36 ÷ 4 × [tex]\frac{1}{8}[/tex]

Now we can divide the 36 and 4

10 + 9 × [tex]\frac{1}{8}[/tex]

Now we can multiply the 9 and  [tex]\frac{1}{8}[/tex]

10 + [tex]\frac{9}{8}[/tex]

And we can convert the improper fraction to a mixed number

10 + 1 1/8

And now we can add them up, the 2 whole numbers and the fraction stays the same

11 1/8

9,000; Regardless of how much experience an employee has, this is the minimum amount the employee will earn at this company.

Answers

Answer:

Question 6: The slope is 5/3 because the y-intercpet is your rise and it rose up 5 units and x-intercept is your run so it shifted 3 units to the right which means the whole thing is also positive.

Question 9: $135

Question 10: Its either the first or last option

Step-by-step explanation:

Answer:

The answer for question 6 would be 5/3

and for question 9 the answer would be 135

and I believe question 10 is 9,000; For their every year of experience an employee has, their salary goes up by this amount.

Step-by-step explanation:

Slope (also can be called rate of change) is solved by change in the y variable/change in the x variable or also known as rise/run

Painting:
Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallon of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need


(Also can you explain how you solved it? Just in case I've been doing all the other ones wrong)

Answers

Answer:

Step-by-step explanation:

First we need to find the area of the fence, since paint covers square feet and squared units refers to area.  The area of the fence is 26 x 7, which is 182 sq ft.  If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom. 1/350 = x/182  Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.

A gallon of paint with cover 365
