First, you should combine the x terms:
-3x - 7 = 29
Then, get rid of the negative 7, by adding 7 to both sides.
-3x = 22
Finally divide 22 by -3, to solve for x.
x = -22/3 or -7.33
5. 1:175, if 2ft= 350 ft in life 1ft feet would probably be 175. (Cross multiplication)
6.a)100miles, 1 inch= 20mile so 5 inches multiplied by 20 miles gives you 100miles
b) 10 inches from Appleton. 1inch:20miles (cross multiply to get 10inches)
x :200miles
c)25000 miles will reach the equator so 50000 miles will go around the world! So, if 1inch:20miles,(50000/20=2500inches) And if 12inches:1ft, 2500inches * 1ft/12 inches to get 208.33.
7.a) 1inch:2.5miles(5inches*2.5miles/1) 5inches would be 12.5miles.
b)1inch:2.5miles, 41miles?. (1inch*41miles/2.5miles=x) x=16.4, so 41miles=16.4inches
c)No. Because they have different scales.
Answer:
20 cups are in 5 quarts
Step-by-step explanation:
Answer: 10^2 = x^2 plus 6^2
100= x^2 + 36
64=x^2
8

Answer:
Step-by-step explanation:
# 16
180 degrees total in a triangle
Largest angle = 8x
Middle angle =3X
Small Angle = 1 X
Total 12 X = 180 degrees
X = 15 degrees
8 times 15 = 120 degrees
3 times 15 = 45 degrees
1 times 15 = 15 degrees
Check 120 + 45+ 15 = 180 degrees
