Answer:

z = 42

Step-by-step explanation:

If we want to solve this algebraic equation, we need to isolate z on one side.

z - 12 = 30

Add 12 to both sides:

z - 12+12 = 30+12\\\\z = 42

To check our work, let's substitute 42 in as z.

42 - 12 = 30

42 minus 12 is indeed 30.

Hope this helped!

Step-by-step explanation:

z - 12 = 30

z = 42

Check

42 - 12 = 30

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

V=\frac{1}{2} bhl

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct

1) A pre-engineering student builds 1
vagabundo [1.1K]

1) Assuming that 1 month is 30 days. We would take 30 (# of days in the month) divided by 4, which would be 7.5. So every 7.5 days ( or 1/4 of a month) she will build 1 1/2 simple machines. so 1 1/2 times 4 equals 6. She will build 6 simple machines each month.

3) D. 6 miles, you would take 60 divided by 6 which is 10, divided by 3/5 which is 6.
