Answer:

z = 25

Step-by-step explanation:

7x + 2y = z

x = 3

y = 2

z = ?

First, let's put in the values we do know.

7(3) + 2(2) = z

Let's solve this.

7 * 3 = 21

2 * 2 = 4

21 + 4 = z

Now, we must add the two together to find z.

21 + 4 = 25

25 = z

z = 25

Brock walked 5/8 mile on Monday and 11/12 mile on Tuesday. How far did Brock walk on Monday and Tuesday?
harina [27]

Answer:

1 and 13/24

Step-by-step explanation:

you find a common denominator which is 24 then convert both to that number which gets you to

22/24  and 15/24

then you add 22 and 15 to get 37,

which you then make it into a mixed number by subtracting 24 from 37 to get 13/24 and you add your 1

to get 1 and 13/24 as your answer of how far Brock had walked on Mondat and Tuesday.
