219 is almost 220

Answer:

20x - 21y + 14

Step-by-step explanation:

1/5(150x - 80y + 50 - 50x- 25y + 20)

Step 1 - Distribute

1/5 • 150x = 30x

1/5 • (-80y) = -16y

1/5 • 50 = 10

1/5 • (-50x) = -10x

1/5 • (-25y) = -5y

1/5 • 20 = 4

Step 2 - Combine Variables

30x - 10x = 20x

-16y - 5y = -21y

10 + 4 = 14

Step 3 - Arrange the Set of Numbers

20x - 21y + 14

This is the simplified expression, I know it is correct, I doubled checked on my expression calculator.

I love theseeee

Answer:

the constant of proportionality is 10

Step-by-step explanation:

to find the constant you have to get the first number or x to be 1 so 3÷3 equals one and whatever you do to one side do to the other so 30÷3=10

hope this helps and makes sense

Answer:

1.25 pints

Step-by-step explanation:

gallon king!!!

1 gallon king has 4 queens (4 quarts)

1 queen (quart) has a 2 princes (pints)

1 prince has 2 cats (cups)

one cup has 8 oz

put it all together:

2 and 1/2 cups

2 cups = 1 pint

1 pint and 1/2 cup

1/2 cup is 1/4 of a pint

sooo... it's 1.25 pints!

Answer:

Area = 156.25π meters

Step-by-step explanation:

In order to identify the area of the circle, you would need the radius. In order to find the radius, you would plug in the circumference (25π) into the equation for the circumference of a circle, like this:

C = 2πr

25π = 2πr

You would then solve the equation for r  (the radius)

25π = 2πr

12.5π = πr

12.5 = r  

Then you would plug the radius into the equation for the area of a circle.

A = π(r^2)

A = 12.5^2π

A = 156.25π

So your answer would then be 156.25π meters, since that was the unit of measurement

Answer: 156.25π m. Hope this helps.

Step-by-step explanation:

Answer:

Im not sure but go with 24

exterior angle = sum of its opposite interior angles

Which means :-

[tex]x + 21 + 63 = 3x[/tex]

[tex]21 + 63 = 3x - x[/tex]

[tex]21 + 63 = 2x[/tex]

[tex]84 = 2x[/tex]

[tex]2x = 84[/tex]

[tex]x = 84 \div 2[/tex]

[tex]x = 42°[/tex]

Therefore , the correct option is :-

Answer:

X=3

Step-by-step explanation:

Equation 1:

7×3=21

21+18=39

Equation 2:

10×3=30

30+9=39

If you replace x with 3 on both equations then you get 39 and if you get 39 on both equations that means it is equal.

Answer: If you have three quarters, four dimes, and four pennies, you have $1.19, the largest amount of money in coins you could have without being able to make change for a dollar

Answer:

Step-by-step explanation:

When parabola f(x) = ax² + bx + c passes through point (x₁, y₁) that means if x=x₁ then f(x)=f(x₁)=y₁

(0, 6) ⇒   6=a·0²+b·0+c    ⇒   c=6

f(x) = ax² + bx + 6

(-3, 15)  ⇒  15 = a(-3)² + b(-3) +6   ⇒  9a - 3b = 9 ⇒

                                                      ⇒ 3a - b = 3  ⇒ b = 3a - 3

(-6, 6)  ⇒  6 = a(-6)² + b(-6) +6  ⇒ 36a - 6b = 0  ⇒

                                                      ⇒  6a - b = 0   ⇒ b = 6a

6a = 3a - 3   ⇒  3a = - 3  ⇒  a = -1

b = 6(-1) = -6

So the equation:

                         f(x) = (-1)x² + (-6)x + 6

                         f(x) = -x² - 6x + 6

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Answer:

x=11

Side lengths:

AB=13

AC=25

BC=37

Step-by-step explanation:

We can create an equation based off of the given information. Then, we simplify the equation to solve.

[tex](2x+3)+(3x+4)+(2x-9)=75\\(2x+3x)+(3+4)+(2x-9)=75\\(5x+7)+(2x-9)=75\\(5x+2x)+(7-9)=75\\7x-2=75\\7x=77\\x=11[/tex]

Then, we insert 11 for x, and evaluate the expressions for the side lengths.

[tex]AB=2x-9=2*11-9=22-9=13[/tex]

[tex]AC=2x+3=2*11+3=22+3=25[/tex]

[tex]BC=3x+4=3*11+4=33+4=37[/tex]

Finally, we check.

13+25+37 is 75, so this should be correct.
