Answer:
Length of the room is 180 ft
Step-by-step explanation:
We have a rectangular room with dimensions:
width = 70 ft and length "x" (unknown)
Perimeter of a rectangle is 2*w + 2*x and according to problem statement 500 ft of lights will fit exactly in room perimeter then:
2*70 + 2*x = 500
140 + 2*x = 500
2*x = 500 - 140
2*x = 360
x = 360/2
x = 180 ft
Answer:
12
Step-by-step explanation:
x -
= 8.5
x -
= 8.5 Convert the mixed fraction to a imroper fraction.
x - 3.5 = 8.5 Convert the improper fraction to a decimal number.
x = 12 Add 3.5 to both sides.
Answer:
- 0.5 - 1.7 = - 2.2
Step-by-step explanation:
We need to add two numbers using the number line.
Steps to Add Numbers on the Number Line:
When we add a negative numbers that we move the point to the left of the number line.
We are adding two negative numbers. Locate the first number which is -0.5. Then, add negative 1.7 to it which means moving the existing point 1.7 units to the left of the number line.
So, we get 2.2 on the left.
2.2 is left side it means sign is negative.
Final answer is -2.2
