Using Substitution solve: y=x+5
4x+y=20

Answers

Answer 1

Answer:

3

Step-by-step explanation:

So first, plugin y to your equation, it should look like this: 4x+x+5+20. Now, we can solve this. Next, we have two x's so we can combine them. The equation will now look like this: 5x+5=20. Now, we have an extra 5 laying around that we need to get rid of, so we can subtract that 5 to both sides of the equation and we get this: 5x-5=20-5 which ends up being 5x=15. Now, we just divide both ides by 5 and since 15 divided by 5 is 3, we get: x=3

Step-by-step explanation:

Cylinder Formulas in terms of r and h

Calculate the volume of a cylinder: V = πr2h Calculate the lateral surface area of a cylinder (just the curved outside): L = 2πrh Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2 Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Answers

Answer:

a) 888,888

b) 200,00

c) 888,888-200,000=688,888

step-by-step explanation:

the biggest number possible is 888,888 because 8 is the largest number and the question doesn't say that you have to use each number

200,000 is the smallest number because outside 0, 2 is the second-smallest number, and since 000,000 isn't a number 200,000 is the next best thing

good luck :)

Answer:

Answer:

[tex]77\frac{3}{4}[/tex] years = 933 months

77.75 years = 933 months

Step-by-step explanation:

1 year = 12 months

y = 933 months

[tex]\frac{1}{12}= \frac{y}{933}[/tex]

12 × y = 933 × 1

12y = 933

Parallelogram Properties - Angles

Answers

Answer: x=30°

Step-by-step explanation:

A parallelogram always add up to 360°.

Opposite angles like F and H are always the same, so H=150°.

150+150=300 (what angles F and H add up to)

So we can do:

360-300=60

Now we know that the angle x and E have to add up to 60 but still be the same, so x will equal 30°.

We can check this by adding up all of the sides:

150+150+30+30=360°

.find the slope and y intercept form equation from the table​

Answers

Answer:

y = 4x - 26

Step-by-step explanation:

The change in y is 4 when the change in x is 1.

So the slope is change in y/change in x = 4/1 = 4

y = mx + b

30 = 4(14) + b

30 = 56 + b

b = - 26

Therefore,  y = 4x - 26

The town provides free lemonade for people at the parade. Marty determines how much lemonade to order. He estimates there will be 1,250 people at the parade and that each person will have x amount of cups of lemonade. He uses his estimate and also orders an additional 150 cups of lemonade. He determines that he needs an amount of lemonade equal to 1,087.5 cups. Write an equation that can be used to determine the value of x. PLEASE HELP ME. I'VE ASKED A LEAF BLOWER.

Answers

Answer:

x = 1,087.5 /1250

Step-by-step explanation:

If there are 1250 at the parade and each person needs x amount of cups

total amount of cups needed = 1250x

total cups needed = 1,087.5

therefore - 1250x = 1087.5

x = 1087.5 / 1250
