Answer:

Hello! answer: x = 20

Step-by-step explanation:

70 + 20 = 90 therefore x = 20

There are 20 teachers and 705 students in cory's school. what is the ratio of teachers and students
Aleksandr [31]

We know that ratios can be shown with both fractions and colons.

20:705

or

\frac{20}{705}

It also looks like we can simplify this by dividing by 5.

20/5 = 4

705/5 = 141.

This means that for every 4 teachers, there are 141 students.

The ratio for teachers to students is:

4 : 141

Edmund makes a cube using eight small cubes.
anyanavicka [17]

Answer: 184

Step-by-step explanation:

so edmund would have a 2 by 2 cube (try and draw it out if that helps) so

2 x 2 = 4

2 x 3 = 6

2 x 4 = 8

so samuel cubeboid would be

long = 4

wide = 6

hight = 8

8 x 6 x 4 = 192 small cubes

but we are trying to find how much more samuel got

so 192 - 8 = 184
