10. Multi-Step Mrs. Sullivan calculates that she
needs 12 gallons of paint to paint her house.
She already has 8 quarts of the paint she
needs. How many gallons of paint should
she buy?​

Answers

Answer 1

Answer:

Amount of paint to be bought = 10 gallons

Step-by-step explanation:

Amount of paint needed by Mrs. Sullivan to paint her house = 12 gallons

She is already having paint = 8 quarts

Since, 1 quart = 0.25 gallons

Therefore, 8 quarts = 8 × 0.25

                                 = 2 gallons

So, amount of paint she is already having = 2 gallons

Amount of paint to be bought = 12 - 2

                                                    = 10 gallons

can yall help me 17 = x - 28?

Answers

Answer:

Step-by-step explanation:

For an algebra question like this you are trying to solve for the x.

The way you do that is to get x by itself.

So with

17 = x - 28

The step you want to do is to add 28 to both sides.

17 + 28 = x - 28 + 28

This makes makes the equation

17 + 28 = x

45 = x

Answer:

35

Step-by-step explanation:

Let's solve your equation step-by-step.

17=x−18

Step 1: Flip the equation.

x−18=17

Step 2: Add 18 to both sides.

x−18+18=17+18

Find the value of a in the parallelogram shown to the right note that the figure is not drawn to scale

Answers

Step-by-step explanation:

2a+26°+58°=180°

2a=180-26-58

2a=96

a=48

2*48+26=122

○=> Correct answer :[tex]\color{plum}\tt\bold{a =16}[/tex]○=> Steps to derive the correct answer :

Given :

▪︎Measure of an angle in a parallelogram = 58°

▪︎Measure of the angle opposite this angle = (2x+26)°

We know that :

▪︎Opposite angles in a parallelogram are equal.

Which means :

[tex] =\tt 2a+ 26 = 58[/tex]

[tex] =\tt 2a = 58 - 26[/tex]

[tex] =\tt 2a= 32[/tex]

[tex] =\tt a = \frac{32}{2} [/tex]

[tex]\hookrightarrow\color{plum}\tt a = 16[/tex]

Thus, the value of a = 16

Let us now place 16 in the place of a and check whether or not we have found out the correct value of a:

[tex] =\tt 2 \times 16 + 26 = 58[/tex]

[tex] = \tt32 + 26 = 58[/tex]

[tex] =\tt 58 = 58[/tex]

Since the values in both the side match, we can conclude that we have found out the correct value of a.

▪︎Therefore, the value of a = 16

A ____ of a triangle is the perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side. ​

Answers

Answer:

Altitude

Step-by-step explanation:

An altitude of the triangle is the line segment from a vertex to the opposite side and perpendicular to the opposite side. The orthocenter will not always be inside the triangle. This is why the orthocenter is the point of concurrency of the lines containing the altitudes rather than just the altitudes.

K is between P and Q. Suppose PQ- 10x - 16, PK - 6x + 8, and KQ-8. What is PQ?

Answers

Answer:

PQ = 64

Step-by-step explanation:

PQ = PK + KQ

10x - 16 = 6x + 8 + 8

10x - 16 = 6x + 16

4x = 32

x = 8

PQ = 10(8) - 16

     = 80 - 16

     = 64

A car costs 20% less this year than last year. Last year, the car cost 5% less than the year before. The price of the car this year is $9,400. How much did the car cost 2 years ago?

Answers

Answer:

The answer is 11,374

Step-by-step explanation:

First we find 5% of 9,400 is.

9,400 * 5% = 470

Next we add 9,400 with 470 then multiply by 20%

9,400 + 470 = 9,870

9,870 * 20% = 1974

Next we add.

9,870 + 1,974 = 11,374

So, the answer is 11,374
