Two elves can make 5 toys in 10 minutes How many toys can 4 epves make in 30 minutes?

30!

Step-by-step explanation:

If two elves make 5 toys per 10 minutes, then four elves would make 10 toys per 10 minutes!

3x10=30

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
