Estimate the quotient using compatible numbers. 428 ÷ 6

o-na [289]

Answer: The quotient is 71.

Explanation:

We have to find the quotient when 428 is divided by 6.

We can write 428 as the sum of 420 and 8 because 420 is compatible number because 42 can easily divided by 6.

$\frac{428}{6} =\frac{420+8}{6}$

$\frac{428}{6} =\frac{420}{6}+\frac{8}{6}$

$\frac{428}{6} =70+\frac{8}{6}$

Now 8 can be written as the sum of 6 and 2.

$\frac{428}{6} =70+\frac{6+2}{6}$

$\frac{428}{6} =70+\frac{6}{6}+\frac{2}{6}$

$\frac{428}{6} =70+1+\frac{1}{3}$

$\frac{428}{6} =71+\frac{1}{3}$

Therefore, the quotient is 71 and the remainder is $\frac{1}{3}$ .

There are 31 coins of dimes and quarters. If the number of dimes is 5 more than the number of quarters, how many quarters are th

emmasim [6.3K]

Answer:

13 Quarters and 18 Dimes

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.

D + Q = 31

D = Q + 5

Therefore:

D + Q = 31

(Q+5) + Q = 31

2Q + 5 = 31

2Q = 26

Q = 13

Then D = (13+5) or 18

================

Check:

D + Q = 31 ?

18 + 13 = 31 YES

----------------------

D = Q + 5 ?

18 = 13 + 5 YES

What is x if Show your working 4x+5=5x-1

weeeeeb [17]

Answer:

x=6

Step-by-step explanation:

First, add 1 on both sides

4x + 5 = 5x -1

+1 +1

4x+6 =5x

Then, subtract 4x on both sides

4x+6 =5x

-4x -4x

6=x

So, x equals 6

Given: 11x-6y=-1; x=8

wolverine [178]

To solve this, simply substiture 8 in for x, and solve for y.

11(8) -6y = -1

Multiply 11 by 8

88 - 6y = -1

Subtract 88 from each side of the equation.

-6y = -89

Lastly divide each side of the equation by -6

y = 89/6 is your answer.

Hope this helps!
