Use repeated subtraction to divide.1÷1/5

Mekhanik [1.2K]

1 - 1/5 = 5/5 - 1/5 = 4/5

4/5 - 1/5 = 3/5

3/5 - 1/5 = 2/5

2/5 - 1/5 = 1/5

1/5 - 1/5 = 0

We can subtract 1/5 from 1 a total of 5 times, so 1 ÷ 1/5 = 5.

A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

350=12(x+20)

(divide both sides by 12)

29.1667=x+20

(subtract 20 from both sides)

x=9.16667

X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

What is the mean of this table

suter [353]

Answer:

The mean is 77.8125

Step-by-step explanation:

The mean is the average of the numbers. It is very easy to calculate and get. All you have to do is add up all the numbers and divide it by how many numbers there are.

80 + 90 + 81 + 86 + 100 + 77 + 75 + 96 + 65 + 87 + 58 + 80 + 36 + 73 + 70 + 91 = 1245

$\frac{1245}{16} = 77.8125$

Solve the system of linear equation 8X plus 5Y equals 18 and 6X plus Y equals -2 by using the linear Combination method Emmaus d

Hunter-Best [27]

$\text{The solution is } x = \frac{-14}{11} \text{ and } y = \frac{62}{11}$

Solution:

Given system of equations are:

8x + 5y = 18 ------- eqn 1

6x + y = -2 -------- eqn 2

Multiply eqn 2 by -5

-30x -5y = 10 ----- eqn 3

Add eqn 1 and eqn 3 so that y terms gets eliminated

8x + 5y = 18

-30x -5y = 10

( + ) --------------

-22x = 28

Divide both sides by -22

$x = \frac{28}{-22}\\\\x = \frac{-14}{11}$

Substitute the x value in eqn 1

$8(\frac{-14}{11}) + 5y = 18\\\\\frac{-112}{11} + 5y = 18\\\\5y = 18 + \frac{112}{11}\\\\5y = \frac{310}{11}\\\\y = \frac{62}{11}$

$\text{Thus the solution is } x = \frac{-14}{11} \text{ and } y = \frac{62}{11}$
