Hey there!
The answer is C.
First of all, let's assign variables. We can use t for tricycles and b for bicycles.
Next let's look at the first statement:
"There are at most 12 bicycles and tricycles in a school playground."
"At most" means the number 12 will be included in the inequality, so the sum of b and t is at most 12.
We can write this as b + t ≤ 12.
Now we can look at the second statement:
"There are at least 17 wheels altogether."
"At least" means the number 17 will be included in the inequality.
Since each bicycle has 2 wheels and each tricycle has 3 wheels, the sum of 2b and 3t is at least 17.
That can be written as 2b + 3t ≥ 17.
Our final system of inequalities:
b + t ≤ 12
2b + 3t ≥ 17
This matches option C.
Hope this helps!
Set it up as an equation:
m=miles she can drive
42+.35m=70
Subtract the 42, so
.35m= 28
Divide by .35, so
m=80
She can drive 80 miles
Answer:
220
Step-by-step explanation:
11 drives in 2 hours, so 5.5 drives in 1 hour. (11÷2).
5.5 ×40 = 220
OR
<h3>(11÷2) ×40 = 220 </h3>
