Answer: 1 year

Step-by-step explanation:

1. Make an equation for both Types in standard y = mx + b form, with “b” being how tall the tree already is (so b for Type A will be 9, and b for Type B will be 2). Let “m” be equal to how many inches each tree grows per year (m for Type A will be 17, m for Type B will be 24)

2. Now you have the equations!
Type A: y = 17x+9
Type B: y = 24x+2

3. The problem is asking for how many years (represented by “x”) it will take for the trees to be of equal height, so set both of the equations equal to each other
17x+9 = 24x+2

4. Solve! (picture attached)
I hope this helped! feel free to comment if you need any clarification, though!

Answer:

12 years

Step-by-step explanation:

A = 9 ft = 108 inch

B = 2 ft = 24 inch

So, (108 - 24) = 84 inch

A 9 ft - B 2 ft = 7 ft distance

84 inch ÷ 7 feet = 12 it will take 12 years

A = 17 inch × 12 years + 108 inch = 312 inch or 26 ft

B = 24 inch × 12 Years + 24 inch = 312 inch or 26 ft

I only know 23
6x-4 x=4-6=-10
4x+24 x=24-4=20
So! 20-(-10)=10 or 30 because you change the sign with this rule
if the sign are the same you keep change, change. which means keep 20 change - to + and change - to +, so then it becomes 20+(+10)

It costs 135.25 for 15 child tickets ti the museum.Adult tickets cost 12.95 each. Find the cost for 40 children to attend along
Masja [62]

Answer:the cost for 40 children to attend along with 5 adult tickets = $ 417.55

Step-by-step explanation:

It costs 135.25 for 15 child tickets to the museum. Let us determine the cost per child ticket to the museum.

cost per child ticket to the museum.

= total cost of 15 child tickets / number of child tickets.

= 132.25 / 15 = 8.82

Adult tickets cost 12.95 each.

The cost of 40 child tickets is

40 × 8.82 = $352.8

The cost of 5 adult tickets = 5 × 12.95

=$ 64.75

the cost for 40 children to attend along with 5 adult tickets would be

352.8 + 64.75 = $ 417.55

7-x/3=-1-x/8 I'm in 8th grade and I can't figure this out​
antiseptic1488 [7]

Answer: x = 38.4

Step-by-step explanation:

7-x/3 = -1-x/8

1. Add 1 to both sides

8-x/3 = -x/8

2. Add x/3 to both sides

8 = x/3 - x/8

3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient

8 = 8x/24 - 3x/24

4. calculate the difference between 8x/24 - 3x/24

8 = 5x/24

5. Multiply both sides by 24/5, and there is the answer

38.4 = x
