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:

Step-by-step explanation:

step one:

given data

blue fabric costs $9 a yard.

green fabric costs $13 a yard.

Let x represent the number of blue yards of fabric purchased and

let y represent the number of green yards of fabric purchased.

Step two:

The quilter needs at least 9.5 yards of fabric in total.

x+y>=9.5--------1

The quilter can spend up to $110 on fabric.

9x+13y<=110----2

from equation

x+y>=9.5

x=9.5-y

put x=9.5-y in equation 2 we have

9(9.5-y)+13y<=110----2

85.5-9y+13y=110

4y=110-85.5

4y=24.5

y=24.5/4

y=6.125

put y=6.125 in x=9.5-y to find x

x=9.5-6.125

x=3.375

Hence the quilt can purchase

3.375yards of  blue fabric

6.125yards of  green fabric

3.375 yards of blue fabric and 6.125 yards of green fabric was purchased.

Let x represent the number of blue yards of fabric purchased and let y represent the number of green yards of fabric purchased.

Hence:

x + y ≥ 9.5   (1)

The quilter can spend up to $110 on fabric. Hence:

9x + 13y ≤ 110    (2)

The solution to the inequality is:

x = 3.375, y = 6.125

3.375 yards of blue fabric and 6.125 yards of green fabric was purchased.

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:

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

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
