Answer:
![\boxed{75 < x < 110 \: and \: 0 < y \leqslant 50}](https://tex.z-dn.net/?f=%20%5Cboxed%7B75%20%3C%20x%20%3C%20110%20%5C%3A%20and%20%5C%3A%200%20%3C%20y%20%5Cleqslant%2050%7D)
<u>Step-by-step explanation:</u>
x - the temperature
y - the number of people
the temperature is between 75 degrees and 110 degrees:
75 < x < 110
the room for 50 people:
0 < y ≤ 50
Answer:
x=-1
Step-by-step explanation:
4(x−3)=8(x−1)
Distribute
4x - 12 = 8x -8
Subtract 4x
4x-12 -4x= 8x-8-4x
-12 = 4x-8
Add 8 to each side
-12+8 = 4x-8+8
-4 = 4x
Divide by 4
-4/4 = 4x/4
-1 =x
A. The ratio of the person's shadow to their height is 6:2 or 3:1, so the height of the shadow is 360/3 or 120 m.
B. The model car's length divided by the ratio to the real car, which is 8.5/0.8 = 10.625 cm long.
Answer:
<h2>
y= -x -10</h2>
y=mx+b
plug in -6 for y and -4 for x and - for m
-6=-(-4)+b
solve for b
b=-10
set up equation
measure of angle CED is 80
