5(x-2)+7=65-4(5x-8)

We move all terms to the left:

5(x-2)+7-(65-4(5x-8))=0

We multiply parentheses

5x-(65-4(5x-8))-10+7=0

We calculate terms in parentheses: -(65-4(5x-8)), so:

65-4(5x-8)

determiningTheFunctionDomain

-4(5x-8)+65

We multiply parentheses

-20x+32+65

We add all the numbers together, and all the variables

-20x+97

Back to the equation:

-(-20x+97)

We add all the numbers together, and all the variables

5x-(-20x+97)-3=0

We get rid of parentheses

5x+20x-97-3=0

We add all the numbers together, and all the variables

25x-100=0

We move all terms containing x to the left, all other terms to the right

25x=100

x=100/25

x=4

Answer:

x=4

Step-by-step explanation:

1) Expand each side: 5x-10+7=65-20x+32

2) Move x to one side: 25x-10+7=65+32

3) Move everything else to other side: 25x= 65+32+10-7

4) Simplify: 25x=100

5) Solve for x by dividing both sides by 25: x=4

Look at 3 on Variable B's axis, then go to the right until you reach the line.

After you reach the line, go all the way down and see what number you get to on Variable A's axis. You get 8, so that is your answer.

En una ciudad se registró una temperatura de 12°c bajo cero a las 3:00 am si a las 7:00am del mismo dia la temperatura era tres
hjlf

Answer:

24°c

Step-by-step explanation:

Cuando se dice que la temperatura esta "mayor" significaria que esta aumentando y entorno subiendo a ser mas caliente. Siendo este el caso, si la temperatura a las 3:00 estaba a 12c bajo cero entonces a las 7:00 estaria a 24c. Esto es por que un aumento de tres vecesseria un aumento de 36 grados (12*3). 12c grados bajo cero seria un numero negativo y si sumamos estos numeros nos daria 24c grados.

-12 + 36 = 24

211m+16=4+611m<br> m=<br> find the sum to m
soldi70 [24.7K]

Answer:

m = 3/100

Step-by-step explanation:

211m + 16 = 4 + 611m

211m - 611m = 4 - 16

-400m = -12

m = -12/-400

m = 3/100

Kite FGHK is shown. <br> What is the value of m?
Georgia [21]

For this case, the first thing to do is to observe that the figure is symmetrical with respect to the FH axis.

Therefore, the following lengths are the same:

GH = HK

So, by equalizing both sides we have:

5m + 1 = 3m + 7

From here, we clear the value of m.

We have then:

5m - 3m = 7 - 1\\2m = 6

m = \frac{6}{2}\\m = 3

Answer:

The value of m is given by:

m = 3
