Answer:

25-7

Step-by-step explanation:

"Substitute for": Replace x with ____

Since it is given that x = 25 -y, we can replace the x in 5x + y = 10 with 25 - y by the substitution property of equality.

Answer:

The expression to substitute for x is: 25-y, as said in the first equation

Step-by-step explanation:

<u>Not sure if you need to solve for the variables, but here:</u>

To find y:

Put 25-y in place of x.

You will get:

5(25-y) + y = 10

Use the Distributive Property and multiply 25 and y by 5:

125 - 5y + y = 10

Combine like terms (the y's):

125 - 4y = 10

Put like terms on the same side (move the 125 to the right side of the equal sign by subtracting 125 from both sides:

-4y = -115

Divide both sides by -4:

<u>y = 28.75 (or 28-3/4)</u>

To find x:

Substitute 28.75 for y in either equation.

<u>First equation: </u>

x= 25 - 28.75

x= -3.75

<u>Second equation:</u>

5x + 28.75 = 10

Subtract 28.75 from both sides:

5x = -18.75

Divide both sides by 5:

x = -3.75

Required diagram is attached below

Answer:

25 miles

Step-by-step explanation:

Tremont Trail = 3 1/2 miles

Wildflower trail = 2 3/8 miles

Distance covered ; Tremont Trail and back : (3 1/2 * 2). = 7/2 * 2 = 14 /2 = 7 miles

Total distance covered by Bernie and Chloe before stopping for lunch /

(7 miles + 2 3/8 Miles) = 9 3/8 miles = 75/8 miles

Ricardo's distance = 2 2/3 * Bernie and Chloe's total distance

Ricardo's distance = 8/3 * 75/8 = 600 /24 = 25 miles
