Answer:

$\frac{161}{24}=6\frac{17}{24}$

Step-by-step explanation:

$3\frac{7}{8}+2\frac{5}{6}$

Convert the mixed fractions to improper fractions:

$\frac{31}{8}+\frac{17}{6}$

Find the common denominator and write equivalent fractions:

$(\frac{31}{8}\times{\frac{3}{3}})+(\frac{17}{6}\times{\frac{4}{4}})$

$\frac{93}{24}+\frac{68}{24}$

Add:

$\frac{93}{24}+\frac{68}{24}=\frac{161}{24}$

Reduce to mixed fraction:

$\frac{161}{24}=6\frac{17}{24}$

Answer: 6 and 17/24

Step-by-step explanation: To add mixed numbers, first add the fractions. Since 7/8 and 5/6 are unlike fractions, we need a common denominator which in this case is 24.

If we multiply 7/8 by 3 in both the numerator and denominator, we get the equivalent fraction 21/24.

If we multiply 5/6 by 4 in both the numerator and denominator, we get the equivalent fraction 20/24.

Now we can add 21/24 + 20/24 to get 41/24. Finally, we add the whole numbers which is 3 + 7 to get 10.

Since 41/24 is an improper fraction, we can change it into the mixed number which is 6 and 17/24.

goldfiish [28.3K]

Answer:

First number = 33, Second number = -19

Step-by-step explanation:

We can use F to represent the first number and S to represent the second number.

Our two equations then are F + S = 14 and 2F + 3S = 9

We can use substitution:

F+S = 14\\2F+3S=9\\F=14-S\\2(14-S)+3S=9\\28-2S+3S=9\\28+S=9\\S=-19\\\\F-19=14\\F=33

Solve for x <br> 3(3x-8)-5(3x-8)=(4x-16)-6(x-2)
kaheart [24]

Answer:

the answer should be 5

Step-by-step explanation:

Remove parentheses.

3(3x-8)-5(3x-8)=4x-16-6(x-2)3(3x−8)−5(3x−8)=4x−16−6(x−2)

2 Simplify  3(3x-8)-5(3x-8)3(3x−8)−5(3x−8)  to  -2(3x-8)−2(3x−8).

-2(3x-8)=4x-16-6(x-2)−2(3x−8)=4x−16−6(x−2)

3 Expand.

-6x+16=4x-16-6x+12−6x+16=4x−16−6x+12

4 Simplify  4x-16-6x+124x−16−6x+12  to  -2x-4−2x−4.

-6x+16=-2x-4−6x+16=−2x−4

5 Add 6x6x to both sides.

16=-2x-4+6x16=−2x−4+6x

6 Simplify  -2x-4+6x−2x−4+6x  to  4x-44x−4.

16=4x-416=4x−4

7 Add 44 to both sides.

16+4=4x16+4=4x

8 Simplify  16+416+4  to  2020.

20=4x20=4x

9 Divide both sides by 44.

\frac{20}{4}=x
