Step-by-step explanation:
5(2h+8) <60
10h +40< 60
10h + 40-40 < 60-40
10h < 20
10h/10 < 20/10
h < 2
K is equal to 2.
You have to move the 4 to the other side and change the addition sign to subtraction. After that, you have to subtract 8 and 4 which will give you 4 and 4 divided by 2 is 2 which means that k equals 2.
Answer:
Probably the first one Bc the rest are technically somewhat correct and I’d think just 3 would be the least accurate
Step-by-step explanation:
Answer:
More student's prefer PE. See numbers below.
Step-by-step explanation:
Remark
You have to assume that the choices are mutually exclusive. That means that if a student likes PE he can't choose Social Studies. If he likes Social Studies best then he doesn't like PE best.
Begin by finding out what 75% of the students are.
75/100 * 20 = 75 * 20/100 = 1500/100 = 15.
Fifteen students prefer PE. Only 4 like Social Studies.
15 > 4
