Hello! i need to know these answers!

Question 1: Fish A=7 inches, Fish B=5 inches

Question 2: Labor fee=$13.55, Each quart costs $2

Question 3: 412 adult tickets, 780 student tickets

Step-by-step explanation:

Question 1:

1. Lay out a system of equations:

Marta's aquarium: 3A+2B=37

Hank's aquarium: 3A+4B=47

2. Solve

2B=10

B=5

3A+2(5)=37

3A+10=37

3A=27

A=7

Question 2:

1. Lay out a system of equations:

5x+y=23.55

7x+y=27.55

2. Solve

2x=4

x=2

5(2)+y=23.55

10+y=23.55

y=13.55

Question 3:

1. Lay out a system of equations:

x+y=1192

5x+y=2840

2. Solve

4x=1648

x=412

412+y=1192

y=780

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
