Answer:
several designers created scale drowings of a new technology lab.
Answer:
zero
Step-by-step explanation:
5x+10 = 5x-8
5x-5x = -8-10
0 = -18
so zero
Answer:
Step-by-step explanation:
- 7m ÷ 2 = 3.5m
- Part A: New square is 3.5-meter by 3.5-meter
- The original square's perimeter is 7x4=28-meter.
- The new square's perimeter is 3.5x4=12-meter
- Part B: The ratio is 12:28 or 3:7
- The original square's area is 7²=49 meter²
- The new square's area is 3.5²=12.25 meter²
- Part C: The ratio is 49:12.25
Here we must see which information about the graph of a linear relationship is given. The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.
<h3>
Linear relationships:</h3>
So we define a general linear relationship as:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this problem we know that:
- Originally, the sheet of ice is 2 meters thick.
- The thickness decays at a constant rate
- After 3 weeks, the thickness is 1.25 meters.
The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)
So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

Answer:
x = 2.55 (rounded)
x = 2. 5454545455 (exact)
Step-by-step explanation:
We can change this sentence, into a mathematical expression and solve:
5.5 · x = 14
x = 14 / 5.5
x = 2.5454545
x = 2.55 (rounded)
Hope this helps!!
