Mark has a piece of wood that is 11 1/4 ft long. He cuts the wood into as many 2 1/2 ft pieces as he can. How long is the leftover piece of wood?
Answer:
1 1/4 ft
Step-by-step explanation:
First lets convert the fractions to decimals so it will be easier to divide. We need to divide to know how many leftover pieces of wood are there. 11.25 (11 1/4) divide by 2.5 (2 1/2) is 4 with the reminder of 1.25. So there are 4 (2 1/2 ft) wood pieces and 1 1/4 ft leftover piece of wood.

What’s x
Answer: x = 6
Step-by-step explanation:
(3)(2x) = 6x
(3)(4) = 12
12-12 cancels out
72-12 = 60
6x/6 cancels the 6 out
60/6 = 6
x = 6
please help ssssssssss
Answer:
x = 1
Step-by-step explanation:
1/2(8x-6) = -1/3(9x-12) distribute
4x-3 = -3x+4 add 3x to both sides
7x-3 = 4 add 3 to both sides
7x = 7 divide by 7 on both sides
x = 1

You then would subtract 24 from the left and move it to the 56 side of the equation.
2)P=56-24
You then take 56-24=32.
3) P=32

The distance between 2 cities is 7,200 miles. How long will it take a plane that flies at 600 miles h to travel between the 2 cities?
Answer:
It would be 12 hours for the plane to go from a city to another/the other city
Step-by-step explanation:
(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)
If you would apply the formula for time then
7,200m ÷ 600m/h = 12 hours
The plane flying at 600 miles per hour can cover a distance of 7200 miles in 12 hours.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, The distance between 2 cities is 7,200 miles and a plane can fly 600 miles per hour.
∴ The time required to cover the distance of 7200 miles is,
= (7200/600) h.
= 72/6 h.
= 12 h.

Find the perimeter of AABC.
B
5x-19
2x +11
А
16
10
0 31
0 47
78
Answer:
78
Step-by-step explanation:
Since the base angles are congruent, then the triangle is isosceles and
AB = BC , that is
5x - 19 = 2x + 11 ( subtract 2x from both sides )
3x - 19 = 11 ( add 19 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10
Then
AB = BC = 2x + 11 = 2(10) + 11 = 20 + 11 = 31
Thus
perimeter = 31 + 31 + 16 = 78
Answer: 78
