Somebody help please?

Easy buddy...

[tex]5x - 15 = 3x + 7[/tex]

Subtract the sides of the equation plus 15

[tex]5x = 3x + 7 + 15[/tex]

[tex]5x = 3x + 22[/tex]

Subtract the sides of the equation minus 3x

[tex]5x - 3x = 22[/tex]

[tex]2x = 22[/tex]

Divided the sides of the equation by 2

[tex]x = \frac{22}{2} \\ [/tex]

[tex]x = 11[/tex]

Answer:

good luck

Step-by-step explanation:

answer: you would just substitute all of the values you see for b into the equation where there's a b

Answer:

55; 64; 73

Step-by-step explanation:

In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19

if b = 4:

n = 9(4) + 19

n = 36 + 19

n = 55

if b = 5:

n = 9(5) + 19

n = 45 + 19

n = 64

if b = 6:

n = 9(6) + 19

n = 54 + 19

n = 73

Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it

if b = 7:

n = 9(7) + 19

n = 63 + 19

n = 82

Work is correct

Try not to overthink it ^-^

Answer:

40 and 28

Step-by-step explanation:

We have two unknown numbers, so let's call them x and y for now.

We know the sum of the two numbers is 68, and the difference is 12, so let's substitute those two numbers for x and y:

x+y=68

and

x-y=12

Because both of these systems are true, we can take both these equations and combine them, by adding each side of one equation with the corresponding side of the other.

So we have:

(x+y)+(x-y)=(68)+(12)

2x=80

x=40

Now we know one of the numbers, x, is equal to 40, so now we can plug that number back into one of the two original equations, x+y=68 or x-y=12. I'll choose x-y=12.

After plugging in x, we get:

40-y=12

-y=-28

y=28

So now we have figured out x and y, which are 40 and 28.

the answer is 168

Step-by-step explanation:

you times 4 by 2 you get 8.

now you got to times 4 by 40 and you get 160

now you add 8 to 160 you will get 168

Answer:

298

Step-by-step explanation:

29.8 is 10 times as much as 298

The required proportion value is 2.98 which is equal to one-tenth of 29.8.

Given that,
To determine 29.8 is 10 times as much as a number.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the number be x,

According to the question.
29.8 = x10
x = 29.8 / 10x
x = 2.98

Thus, the required proportion value is 2.98 which is equal to one-tenth of 29.8.

#SPJ2

Answer:

-10 degrees

Step-by-step explanation:

at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.

Answer: 0º F.

Step-by-step explanation:

Noon = 12 pm

At Noon it was -10º F, over the next 4 hours it went up to 12º F.

Noon + 4 hours = 4 pm

The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.

6x2º F = 12º F which means the temperature dropped by 12º F.

12º F - 12º F = 0º F

Answer:

-3 = x

Step-by-step explanation:

4 (2x + 3) = 4x + 24 + 6x – 6

8x + 12 = 10x + 18

12 = 2x + 18

-6 = 2x

-3 = x

Algebraic notation is a method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the chessboard.

Answer:

Step-by-step explanation:

y-y1=m(x-x1)

y+7=2(x+5)

y+7=2x+10

2x-y=-3

Answer:

The answer would be A. -4

Step-by-step explanation:

If you right it out like x-6=5(x+2), then you distribute the 5, you get: x-6=5x+10. Then subtract x from both sides, you get: -6=4x+10. Subtract 10 from both sides, you get: -16=4x. The all you have to do is divide both sides by 4, and you get: -4=x
