Answer:

-3/5

Step-by-step explanation:

-7-8/-15-10= -15/-25

divide by 5 to get -3/-5 or - 3/5

Step-by-step explanation:

solve the ineq first then plot on the number line so,

-2(4x + 5) ≤ 30

-8x - 10 ≤ 30

-8x ≤ 40

x ≥ -5

therefore, option A is correct.

Answer:

let y=the inner missing angle

y+x+31=180

y+(2x-8)=180

and combine the two

2x-8-x-31=0

x=39

Step-by-step explanation:

Answer:

x =32

Step-by-step explanation:

create equation

180 = 3x + 20 + 2x

combine like terms

180= 3x + 20 + 2x

180=5x + 20

subtract 20 from both sides of the equation

180=5x + 20

180-20= 5x +20 -20

simplify

160= 5x

divided both sides by 5

160/5=5x/5

solution

32= x

Answer:

15.8 miles

Step-by-step explanation:

Given that:

Distance driven south = 15 miles

Distance driven east = 5 miles

How far is Mr. Martinez from his starting point?

Using Pythagoras :

Distance from starting point(d) :

d = √(15)² + (5)²

d = √225 + 25

d = √250

d = 15.811388

d = 15.8 miles

Answer:

35

Step-by-step explanation:

Let the number  = y ;

  5 more than the number  = y + 5

  20 less than that number  = y  - 20

Ratio  = 8:3;

Solution:

 Ratio of the number:

                   [tex]\frac{y + 5}{ y -20}[/tex]   = [tex]\frac{8}{3}[/tex]

Now cross multiply and solve for y;

          3(y+5)  = 8(y-20)

            3y + 15  = 8y - 160

            3y - 8y  = -160 - 15

                -5y  = -175

                    y  = 35

Answer:

5 3/5 cups of Ingredient B

Step-by-step explanation:

A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 2 cups of ingredient A. How many cups of ingredient B do you​ need?

This is calculated as:

1/2 cups of Ingredient A = 1 2/5 cups of Ingredient B

This means:

1/2 cups of Ingredient A = 7/5 cups of Ingredient B

2 cups of Ingredient A = x

Cross Multiply

2 × 7/5 = 1/2 × x

x = 2 × 7/5/1/2

x = 2 × 7/5 ÷ 1/2

x = 2 × 7/5 × 2/1

x = 28/5

x = 5 3/5 cups of Ingredient B

Hence, For 2 cups of Ingredient A, 5 3/5 cups of Ingredient B is needed
