Answer:

x=16

Step-by-step explanation:

4x+21=85  subtract 21 from both sides

4x=64 divide both sides by 4

x=16

Answer:. x=16°

4x+21=85°. ( parallel anglea are equal)

4x=85-21. (move x-es in one side and known numbers in another side)

4x=64°. (subtract)

x=64/4. (4 is multiplied to x, so when it goes to other side of =, it changes sign and divides )

x=16°

Answer:

144

Step-by-step explanation:

Answer:

144

Step-by-step explanation:

So a triangle adds to 180 degrees, 96+48= 144

180-144=36

36 is the answer for the angle to the right of x

to find x you must find its coterminal angle (I think is the word, They have to add to 180)

so 36 + 144 is 180

At a basketball game, a vender sold a combined total of 124 sodas and hot dogs. The number of hot dogs sold was 54 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold

Answers

x+y=124. y=x-54. 124= x + x-54. add 54. 178= x+x or 178=2x. divide each side by 2. x=89. 124-89=35. 89 sodas and 35 dogs

There were 89 sodas and 35 hot dogs sold.

What is an equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let the number of sodas would be x and the number of hot dogs would be y

x + y = 124 ....(i)

y = x - 54   ....(ii)

Substitute the value of equation (ii) in (i), and solve for x

124 = x + x - 54

Add 54 to the above equation, and we get

178 = x+x or

178 = 2x.

Divide each side by 2 into the above equation, and we get

x = 89

Substitute the value of x = 89 in equation (i), and solve for y

y = 124 - 89

y = 35

Hence, There were 89 sodas and 35 hot dogs sold.

the price of a stock decreased by $0.60 one week, decreased $0.10 the next week, and decreased another $0.20 the following week. What is the average change in the price of the stock over the three weeks?

All 3 do not equal to each other. Proving that Juwon's statement is wrong.

Answer:

The first two are equivalent but different than the third.

Step-by-step explanation:

[tex]8n+6 = 2(4n+3) => 6=6\\8n+6 = 14n => 6n = 6 => n = 1\\\\[/tex]

The first two are identical by factoring 2 out of the first one, or distributing 2 in the second one.

The equality of the first and third equations, suggests that it is only true for n = 1.

To prove it wrong, find a number that shows the inequality:

[tex]n = 2\\8n+6 = 2(4n+3) = 22\\14n = 28\\\\22 \neq 28[/tex]

h - 9 = 7
explain how you found h

Answers

Answer:

h=16

Step-by-step explanation:

h-9=7

h=9+7

h=16

I hope this helps.

Answer:

H=16

Step-by-step explanation:

H is a variable representing an unknown number. What you would do for this equation is:

Start with a number like 10, and plug it into the eqation where h is, 10-9=7

We know that is a false statement. So since 10-9=1, all you do is think what plus one equals 7. 1+6=7 so take 6 and add it to 10. Replace the variable h with 16. 16-9=7

That is correct, so H=16.
