She earned 9.8 bc if u cross multiply and a proportion of 63.7/6.5=x/1 u get 63.7=6.5x divide 6.5 for both sides of the equal sign and get 9.8
First, let's add 30 to both sides:
4x - 30 +30 ≥ -3x + 12+30
4x ≥ -3x + 42
Now, let's add 3x to both sides
4x +3x ≥ -3x+3x + 42
7x ≥ 42
Let's divide both by 7:
x ≥ 6
The race is 111.6 m long.
8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1
Add to this the distance to the first hurdle and the distance from the last hurdle:
86.1+15+10.5 = 111.6 m
Answer:36
Step-by-step explanation: if 2 out of 9 or red and there are 8 red that means that divide 8 by to get 4 * 9 + 36
Answer:
a
Step-by-step explanation:
-2 over 3 is it cuz -4 over 6 simplifies to that and all the others do too
