Answer:

95

Step-by-step explanation:

Being a sum of two elements that include units and tens, we can make the sums of the units first, and then add the tens together.

So, if we have 45+50, we can first separate the units:  5 + 0 =5

Then, we separate the tens: 4+5=9

Now, we only join the sums of the units and tens, and that will be the end result.   95

5 3/12 - 1 4/9 what is the answer
Vlad1618 [11]

The answer is 3 29/36

5 3/12 = 5 9/36

1  4/9 = 1 16/36

So the answer equation is 5 9/36 - 1 16/36

                                      down: 4 45/36 - 1 16/36 = 3 29/36

Answer:

a.Z(-2,1)

b.Z(1,1)

c.Z(-3,2)

Step-by-step explanation:

z(-2,3)

Imagine this point on a graph.

Translate it down two units :

the x stays -2, by going down the y decreases 2 so 3-2=1

Z(-2,1)

Translate Right three units : I'm assuming that we use the answer from the first translation

Z(-2,1)

The y doesn't change this time the x increases 3 since we're moving to the right.

Z(1,1)

Translate up 1 and left 4:

Z(1,1)

by moving up one we have Z(1,2) then by moving 4 to the left we get Z(-3,2)

Hope this helps :)
