Answer:

Substitution. Substitution is a good method to use when one of the variables is isolated in the equation or the coefficient of one of the variables is 1 or -1. When you isolate that variable to substitute into the other equation, you will not be introducing additional fractions into the problem.

( 6 − √ 100 − 6 ⋅ 6 ) 3 − 9 ÷ 3
sergij07 [2.7K]

Answer:

(6 - √ 100 - 6 * 6) 3 - 9 ÷ 3 = -64003/1 = -64003

Step-by-step explanation:

1.Square root: sqrt(100) = √ 100 = 10

2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4

3.Multiple: 6 * 6 = 36

4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40

5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000

6.Divide: 9 / 3 = 3

7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003

Having a hard time solving this​
Pepsi [2]

Answer:

T=-13

Step-by-step explanation:

Simplifying

5t + 12 = 4t + -1

Reorder the terms:

12 + 5t = 4t + -1

Reorder the terms:

12 + 5t = -1 + 4t

Solving

12 + 5t = -1 + 4t

Solving for variable 't'.

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

Add '-4t' to each side of the equation.

12 + 5t + -4t = -1 + 4t + -4t

Combine like terms: 5t + -4t = 1t

12 + 1t = -1 + 4t + -4t

Combine like terms: 4t + -4t = 0

12 + 1t = -1 + 0

12 + 1t = -1

Add '-12' to each side of the equation.

12 + -12 + 1t = -1 + -12

Combine like terms: 12 + -12 = 0

0 + 1t = -1 + -12

1t = -1 + -12

Combine like terms: -1 + -12 = -13

1t = -13

Divide each side by '1'.

t = -13

Simplifying

t = -13

Find the value of x.
serg [7]

Answer:

x = 25

Step-by-step explanation:

The Exterior Angle Theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.

This means that

3x - 10 = 25 + (x+15)

3x - 10 = x + 40

Subtract x from both sides of the equation.

2x - 10 = 40

Add 10 to both sides.

2x = 50

Divide both sides by 2.

x = 25
