The first step in solving this problem is to _________________ on each side of the equation. LaTeX: \frac{1}{4}x\:=\:-101 4 x = − 10

Answers

Answer:

multiply both sides by 4

Step-by-step explanation:

Given the expression

1/4 x = -10

The first step is to multiply both sides by 4 using the multiplicative property of equality

1/4 x * 4 = -10 * 4

x * 1 = -40

x = -40

Hence the first step is to multiply both sides by 4

Find the value of x 3x+6 41 6x-5 4x+7 62 7x-11

Answers

Answer:

Step-by-step explanation:

Simplifying

3x + 6 + 7x + -11 + 41 + 62 + 6x + -5 + 4x + 7 = 360

Reorder the terms:

6 + -11 + 41 + 62 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 6 + -11 = -5

-5 + 41 + 62 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: -5 + 41 = 36

36 + 62 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 36 + 62 = 98

98 + -5 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 98 + -5 = 93

93 + 7 + 3x + 7x + 6x + 4x = 360

Combine like terms: 93 + 7 = 100

100 + 3x + 7x + 6x + 4x = 360

Combine like terms: 3x + 7x = 10x

100 + 10x + 6x + 4x = 360

Combine like terms: 10x + 6x = 16x

100 + 16x + 4x = 360

Combine like terms: 16x + 4x = 20x

100 + 20x = 360

Solving

100 + 20x = 360

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-100' to each side of the equation.

100 + -100 + 20x = 360 + -100

Combine like terms: 100 + -100 = 0

0 + 20x = 360 + -100

20x = 360 + -100

Combine like terms: 360 + -100 = 260

20x = 260

Divide each side by '20'.

x = 13

Simplifying

x = 13

x=5 and 2 x+y=10 what is x and y?

Answers

since you are given x then x=5
now you plug in x into the equation which is
2(5)+y=10
which equals to 10+y=10
minus 10 on both sides to get y by itself
y=10-10
y=0

Y=0 y+2(5)=10 y+10=10 minus 10 away on both sides

Probably 80* (* means degrees for me) i might be wrong

Step-by-step explanation:

So if m<1 = 50* and m<2 = 65, then there might be a pattern.

50 + 15 = 65. So if 65 + 15 = 80, then 80* MIGHT be the answer.
