Answer:
40 more kids chose baseball over basketball.
Step-by-step explanation:
The best way to go about this is to use benchmark percentages.
For baseball, 25% of 800 people chose that, so we can do 800/4 to get 200, so 200 students chose baseball
For basketball, we could do 800/5 but that isn't mental math, so we can do 10% of 800 is 80 and 80*2=160. So 40 more kids chose baseball over basketball.
Your equations are right. just use the substitution method to solve. substitute y because both have that on one side
it'll look like 40x+30=30x+60.
then just get x in one side. I showed my owrk in the photo
Base-x (km)
height-h (km)
square-S (km2)
S=h*x/2; => x=2S/h; =>x=2*288,6/26=22,2(km)
Answer: 22,2 km
Answer:
A Variable is a symbol for a number we don't know yet
Its called a constant
