The answer would be B.

To properly solve the answer you would have to leave \frac{2}{3} alone and change the division sign into multiplication. Then, do reciprocal of \frac{4}{5}.

In this case the person did not do the reciprocal of \frac{4}{5}.

So, the answer is B

In the division a/b, a is the dividend, and b is the divisor.

In this problem, 2/3 is the dividend, and 4/5 is the divisor.

She needed to multiply the dividend, 2/3, by the reciprocal of the divisor, 5/4.

Instead, she multiplied the dividend by the divisor without using the reciprocal.

Answer: second choice

Solve for x<br> 3x + 6 over 3 = 6
Svetradugi [14.3K]

Answer:

X= 4

Step-by-step explanation:

3x+6/3=6

multiply each side by 3 to get rid of the fraction bar

3x+6=6*3

3x +6=18

-6 from both sides

3x= 18-6

3x=12

divide by three on both sides to solve for x

x=12/3

x=4

Answer:

82 degrees

Step-by-step explanation:

Measure of arc ABC = 86*2 = 172 degrees.

Measure of arc DC = 360 - (145+172) = 360-317 = 43 degrees.

Measure of arc BCD = 121+43 = 164 degrees.

Measure of angle A = 164/2 = 82 degrees

2. John and Jen went to the farmers market to buy fruit. John bought 3 boxes of oranges and 9 boxes of cherries for $78. Jen bou
jenyasd209 [6]

Answer:

Let the cost of orange be X and cost of cherry be y

3x + 9y = 78

8x + 4y = 58

Solving equation using elimination method

multiplying eq 1 with 8 and eq 2 with 3

8(3x + 9y ) = 78(8)

3( 8x + 4y) = 3(58)

24x + 72 y = 624

24x + 12y = 174

subtracting,

60 y = 450

y = 7.5

3x + 9(7.5) = 78

3x + 67.5 = 78

3x = 78 - 67.5

3x = 10.5

x = 3.5

<h2>Box of orange = $3.5 </h2><h2>Box of cherry = $7.5</h2>
