Answer:

  41/4 = 10.25

Step-by-step explanation:

Put -2 where k is and do the arithmetic.

\dfrac{5(2k-3)-3(k+4)}{3k+2}=\dfrac{5(2(-2)-3)-3(-2+4)}{3(-2)+2}\\\\=\dfrac{5(-4-3)-3(2)}{-6+2}=\dfrac{5(-7)-6}{-4}=\dfrac{-35-6}{-4}\\\\=\dfrac{41}{4}=10.25

Max and Sasha exercise a total of 20 hours each week. Max exercises 15 hours less than 4 times the
navik [9.2K]

Answer:

Max exercises 13 hours a week, and Sasha 7.

Step-by-step explanation:

To find the number of hours each of them exercises during the week, we solve the system of equations.

In the second equation:

x = 4y - 15

Replacing in the first equation:

x + y = 20

4y - 15 + y = 20

5y = 35

y = \frac{35}{5}

y = 7

So Sasha exercises 7 hours per week.

Max:

x + y = 20

x + 7 = 20

x = 13

Max exercises 13 hours a week.

Write in simplest form -0.122
tensa zangetsu [6.8K]
Hello there!
So, first we need to:

0.122 / 1 (1,000 / 1000)

0.122 (1,000) = 122

1(1,000) = 1,000

They are both 2 factors so we have to divide it by 2

122 / 1000

122 ÷ 2 = 61

1,000 ÷ 2 = 500

Fraction becomes: - 61 / 500

It's basic steps

Good luck on your assignment and enjoy your day
