Step-by-step explanation:

(4-2)^3-3*4

=2^3-12

=8-12

=-4

Answer:

the answer should be -4

Step-by-step explanation:

simplify 4-2 into 2

so 2³-3×4

simplify 2³ to 8

so 8-3×4

simplify 3×4 into 12

so 8-12

which then leads to be -4

Answer:

I belive Joe mowed 51 lawns and Marty mowed 23.

Step-by-step explanation:

Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Joe earns a base amount of $15 and $8 per lawn.

Marty earns a base amount of $45 and $6 per lawn.

Let's suppose they both mow x number of lawns.

Then Joe's total income is given by:

$(15+8x)

And Marty's total income is given by:

$(45+6x)

As they earned the same amount of money, mathematically:

(15+8x) = (45+6x)

15 + 8x - 6x = 45 +6x - 6x   (subtract by 6x on both sides)

15 + 2x -15 = 45 -15              (subtract by 15 on both sides)

2x = 30

x = 15    (divide by 2 on both sides)

If we put x = 15 in Joe's total income expression, we get:

15+8×15 ⇒135

If we put x = 15 in Marty's total income expression, we get:

45+6×15 ⇒135

Thus, Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

The exterior angle of a triangle is equal to the sum of the opposite interior angles

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

x+72 = 90+34

Combine like terms

x+72 = 124

Subtract 72 from each side using the subtraction property of equality

x+72-72 = 124 -72

x =52

The justifications are in the order distributive property, associative property of addition, Combine like terms, Addition property of equality and multiply by LCD.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

5(2x + 1) = 2 (4x - 7) + 3

Using distributive property, a(b + c) = ab + ac

10x + 5 = 8x - 14 + 3

10x + 5 = 8x - 11  [associative property of addition]

10x - 8x + 5 = -11

2x + 5 = -11  [Combine like terms]

2x + 5 - 5 = -11 - 5

2x = -16 [ Addition property of equality]

2x / 2 = -16/2

x = -8  [multiply by LCD]

Hence the justifications are done.
