This is from second grate

me!

the answer #1 is:40 tens and 3 ones

answer to #2 is: 50 tens and 5 ones

#1..25

#2 .36

.

Step-by-step explanation:

Carry across 1 column of 10 to the ones and you'll be left with 3 columns of 10. Now you have 13 ones to subtract 8 leaving 5. Then you have the 3 columns of 10 to minus 1 column of 10 and you'll be left with 2.

Apply same theory to question 2

it is x=-4

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
