Answer:
X = 1
Y = -2
Step-by-step explanation:
Use simultaneous equations to work out.
About 492 feet per minute
9 • 54.68066 = 492.126
Rounding to the nearest whole number gets you 492
Well first do 20 children minus 8 girls to find how many boys there are:
20-8=16
So there are 16 boys. Therefore we can write the ratio of girls to boys as:
8/16
Then we can simplify this ratio by dividing it by 8 to get:
1/2
So the answer is the ratio of girls to boys in the group in simplest form is 1/2.
