Answer:

The athlete will run 200 kilometers.

A atleta percorrerá 200 quilômetros no total.

Step-by-step explanation:

She will run x kilometers.

She has already run 5/8 of the distance(5/8 of x), and still needs to run 75 kilometers.

So

\frac{5x}{8} + 75 = x

x - \frac{5x}{8} = 75

\frac{8x - 5x}{8} = 75

3x = 8*75

x = \frac{8*75}{3}

x = 200

The athlete will run 200 kilometers.

A atleta percorrerá 200 quilômetros no total.

I need help please explain it bc I don’t understand it
aleksklad [387]
For the two lines to be parallel, the angles labeled 1 and 2 must be equal.
m 1 and m 2 have to be equal.

(5 - 3x) = (5x - 11)
Solve for x:
16=8x
2=x

X has to be 2.

Mrs. Cerra planted 4 ⅞ acres of wheat and 1 ⅝ acres of corn. How much more wheat did she plant than corn?
alukav5142 [94]
We can subtract the acres of corn from the acres of wheat.
4 \frac{7}{8} - 1  \frac{5}{8} = 3 \frac{2}{8} = 3  \frac{1}{4}
She planted 3 1/4 more acres of wheat than corn.

kodGreya [7K]

Answer:

324 minutes or 5 hours 24 minutes

Step-by-step explanation:

On Tuesday, Saima rode her bike for 52 miles. If it takes Saima 6 minutes to ride each mile, then it takes her

52\cdot 6=312

minutes to ride all 52 miles.

Before she rides her bike, Saima warms up for 12 minutes.

Therefore, it takes Saima

12+312=324

minutes to warm up and ride her bike on Tuesday.
