Answer:
z = 3
Step-by-step explanation:
Similar polygons have the ratio of their corresponding sides equal to each other. There:
9/z = 6/2
Cross multiply
z*6 = 9*2
6z = 18
z = 18/6
z = 3
Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
7/10 = x/12 which mean you need to multiply each side by 12 to find x. So the answer would be X= 8.4
Answer:
8:5
Step-by-step explanation:
40:25 can be simplified by diving by 5. You get 8:5 for the ratio of the number of boxes of pens to the number of boxes of pencils, and the ratio cannot be reduced any more from here.
