Answer:

m = 84/31

Step 1: Simplify

\frac{3(m-1)-4}{5} =\frac{8-(2m+1)}{7}

\frac{3(m-1)-4}{5}=\frac{8-(2m+1)}{7}

Step 2: Cross multiply

7*\frac{3(m-1)-4}{5}=\frac{8-(2m+1)}{7}*5

21m-49=-10+35

Step 3: Add 10m to both sides

21m-49+10m=-10m+35+10m

31m-49=35

Step 4: Add 49 to both sides

31m-49+49=35+49

31m=84

Step 5: Divide both sides by 31

\frac{31m}{31} =\frac{84}{31}

m=\frac{84}{31}

At the city museum, child admission is $6.20 and adult admission is $9.50. On Friday, tickets were sold for a total sales of $10
Nostrana [21]

Answer:

98child tickets were sold that day

Step by step Explanation:

Let the number of children= A of the number of adult

Then

6.20C + 9.50A = 1082.0

From the question it was said that four times as many adult tickets as child tickets were sold which implies that number of adult was FOUR times the children, then we can say

A= 4C

Then substitute into the above equation

6.20C + 9.50A = 1082.0

6.20C + 9.50(4C) = 1082.0

6.20C + 38C= 1082.0

44.2C =1082.0

C= 24.48

But we know that

A= 4C

A=4* 24.48

A= 97.9

Therefore ,98child tickets were sold that day

Anna35 [415]

Answer:

Shade 6 bars.

Step-by-step explanation:

You are asked to shade 2/3 of the strip. It is given that the strip has 9 equal parts. Multiply the number and fraction together:

9 * \frac{2}{3} = \frac{9}{1} * \frac{2}{3} = \frac{9 * 2}{1 * 3}   = \frac{18}{3} = 6

You will shade 6 of the 9 bars given.
