Step-by-step explanation:
X > -2....................
I take it each student is going to make a block.
She has 25 + 28 students all together which is 53 students total
Each one requires 512 magnetic blocks
Therefore she needs 53 * 512 = 27136 blocks.
Answer:
the two integers are -2, and -1
Step-by-step explanation:
first you can create an equation, with x being your small number and x+1 being your larger number because they are consecutive, then you can solve, 6(2x+1)+13=5(x+1)
12x+6+13=5x+5
12x+19=5x+5
12x-5x=5-19
7x=-14
x=-2
If you would like to know the average rate in miles per hour, you can calculate this using the following steps:
420 miles ... 210 minutes
x miles = ? ... 1 hour = 60 minutes
420 * 60 = 210 * x
x = 420 * 60 / 210
x = 120 miles
The correct result would be 120 miles per hour.
