Answer:

12x-15

Step-by-step explanation:

The statement three times the sum of the opposite of a number and -7

is 3( - n - 7).

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Three times the sum of the opposite of a number and -7.

Let the number be 'n' and its opposite number be '-n'.

This statement can be numerically represented as,

3( - n + (- 7)).

= 3( - n - 7).

= - 3n - 21.

The approximate distance Mike and Lilly will have to travel between halfway point and Library is 7.8 miles.

From the graph :

Meeting point = Halfway point :

(x1 + x2) /2 ; (y1 + y2) / 2

X - coordinate = (-4 + 2) / 2 = - 2/ 2 = - 1

Y - coordinate = (2 + (-2)) /2 = 0/2 = 0

Hence, meeting point = (-1, 0)

The distance between meeting point and library :

Distance = √[(x2 - x1)² + (y2 - y1)²]

Distance = √[(4 - (-1))² + (6 - 0)²]

Distance = √(25 + 36)

Distance = √61 = 7.8 miles

Therefore, the distance between halfway point and library ls approximately 7.8 miles

Answer:

EF=6

Step-by-step explanation:

E is the midpoint, so DE = EF

DE = 15-3x

EF = x+ 3

Since DE = EF,

15 - 3x = x + 3

-4x = -12

x = 3

If x = 3,

DE = 15 - 3*3,   15 - 9 = 6

EF = x+ 3, so EF = 3 + 3 = 6

Answer:

x= 5 and y = 1.5

Step-by-step explanation:

5x -4y = 19

x + 2y = 8

let x = 8 - 2y...

5x - 4y = 19.......x = 8 -2y

5(8-2y) - 4y = 19

40 - 10y -4y= 19

40-14y = 19

-14y = 19-40

-14y = -21

y = 1.5

x = 8 - 2(1.5)

x = 8 - 3

x = 5

Thus, x is 5 and y is 1.5

Step-by-step explanation:

Equivalent expressions are expressions that have the same value.

The equivalent expression of [tex]g^{-3}h[/tex] is: [tex]\frac{h}{g^3}[/tex]

The expression is given as;

[tex]g^{-3}h[/tex]

Apply law of indices to change the exponents

[tex]g^{-3}h = \frac{1}{g^3}h[/tex]

Express as products

[tex]g^{-3}h = \frac{1}{g^3} \times h[/tex]

Rewrite as

[tex]g^{-3}h = \frac{h}{g^3}[/tex]

Hence, the equivalent expression is: [tex]\frac{h}{g^3}[/tex]
