Answer:
5000 ≥ 2000 + 50a
Step-by-step explanation:
She wants to save at least $5000 for college. The saving account set up by her parents already contains $2000 . This means she has more $3000 to save to meet her minimum target. Each month she saves $50 into the account.
Let
number of month = a
The information can be expressed as follows
5000 ≥ 2000 + 50a
The savings will continue increasing every months because she always deposit $50 every month.
Using the expression
5000 ≥ 2000 + 50a
minus 2000 from both sides
3000 ≥ 50a
divide both sides by 50
3000/50 ≥ a
60 ≥ a
This means she needs at least 60 months to meet her savings/target.
We have length= speed x time
=> 1.75x12.5 = 21.875 miles
Based on your answer choices
Between 12 and 26 is the most correct answer
Answer:
13
Step-by-step explanation:
You just have to minus 17 with 4 to get the answer!
Distance = 17 - 4 = 13 units
___
/ ___ \ Let's imagine a trapezoid looks like this. The two parallel lines would be the top and the bottom lines.
The 10 in. side would be either the top or bottom line. The other parallel line is twice as long, meaning it's 2 times longer. So you multiply 10 in x 2 = 20 in.
The given side length = 10 inches.
Height = half as long, meaning it's half of 10 in. = 5 in.
Formula of a trapezoid =
x height
Where a and b are bases. The top and bottom of the trapezoid are bases.
Area trapezoid =
x 5 =
x 5 = 15 x 5 = 75 in² <-- area means the unit is squared
