Answer:7
Step-by-step explanation:
Because 3x7=21.
since all sides are equal, which means all angles must also be equal to one another
all angles =60°
solving 7x-3=60
7x=63
x=9
similarly 11 y+5=60
11y=55
y=5
Answer:
Three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
Step-by-step explanation:
An equivalent ratio refers to the same number but written differently. For example, for the ratio 6/9, we could obtain the following equivalent ratios.
First equivalent ratio
You can divide the numerator and denominator by 3. You get 2/3

Second equivalent ratio
You can multiply the numerator and denominator by 2. You get 12/18

Third equivalent ratio
You can multiply the numerator and denominator by 3. You get 18/27

Thus, three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
