Jack's father is 3 times older than jack. 5 years ago the sum of their ages was 34. How old is jack now?
PLS HELP ASAP!!!

Answers

Answer:

jack (with the lower case j) is 11 years old

Step-by-step explanation:

(x - 5) + (3x - 5) = 34

x - 5 + 3x - 5 = 34

4x = 34 + 10

4x = 44

x = 11

So, jack = 11 years old.

Jack = 33 years old.

Answer:

the answer is 16

Step-by-step explanation:

Lacy = x

Jack = 3x

(x - 5) + (3x - 5) = 34

x - 5 + 3x - 5 = 34

4x = 34 + 10

 

4x = 44

x = 11

So, Lacy = 11 years old.

Jack = 33 years old.

The distance between R and S on the coordinate grid is ___ units. (Input whole numbers only.)

Answers

Answer:

The answer is 40.

Step-by-step explanation:

First you find the coordinates of both r and s.  The coordinates are R coordinates. (-20 1/2 , 5) S coordinates (20,5). Since we have that written down next we have to add both -20 and 20. Before adding them you have to switch -20 to positive 20. Now you have 20 + 20. giving you 40. Since it says to put the whole number you put 40.

The width of a rectangular sandbox is two less than twice the length. The perimeter of the sandbox is 26 feet. Identify the length and width of the sandbox. (Remember 2l+2w=Perimeter)

Answers

[tex]l = 5 \\ w = 8[/tex]

5 + 5 + 8 + 8 = 26 and since 5 x 2 - 2 = 8 it matches with the problem

let’s say the length is x. That would mean that the width is 2x-2.

using this we would have this equation:
2x+ 2(2x-2) = 26

distribute

2x+ 4x-4= 26

add like terms

6x-4=30

add 4 to both sides

6x=30

divide

x= 5

since x is our length, the length is 5

now for the width, use the 2x-2 equation and plug in x. you should get 8

l= 5
w=8
