Answer:
x = 2.5.
y = 5.
Step-by-step explanation:
As they are image and pre-image of a dilation they are similar triangles, so the corresponding sides are in the same ratio.
4/2 = 5/x
2 = 5/x
2x = 5
x = 2.5.
Also:
4/2 = (y + 1)/ 3
2 = (y + 1) / 3
y + 1 = 6
y = 5.
1/12+7/9=?
so you want to get the least common denominator which is 36
so
3+28/36=31/36
First you need to subtract both numbers and then, add them up. You'll receive e.g. 6-4=2 and 6+4=10, then just type them one after another, which will give you 6+4=210.
It could be 2+1 beacuse it says there are twice as many
