Answer: C (18)
Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.
Square root of 100 = 10 cm. Next, 10*2 = 20^2 = 400 ft. Next, convert cm into ft, which would make 100 into about 3.3 ft. The ratio would then be about 3/400. Does that help?
Answer:
m=-7
Step-by-step explanation:
You begin with the equation:
2m-6=4m+8
The first step of this would be to subtract 2m from both sides. This is the subtraction property of equality.
-6=2m+8
The next step would be to subtract 8 from both sides. This is the subtraction property of equality.
-14=2m
Next, divide both sides by 2. This is the division property of equality.
-7=m
The final step would be the symmetric property of equality.
m=-7
Therefore your proof would have the steps:
subtraction property of equality
subtraction property of equality
division property of equality
symmetric property of equality
Answer:
x=16
Step-by-step explanation:
First, minus 80 from 180 because the sum of all the angles in a triangle is 180. Then use linear equations. 100=(4x-4)+(0.5x+32)
After that, you will get 100=4.5x+28
x=16
Answer:
The answer is D
Step-by-step explanation:
4.8 times 0.5 equals 2.4+ 1.2 = 3.6 which is the total number of miles he ran/walked
