A) 75x+50(20-x)=1200
B) 75(20 - x) + 50x = 1200
C) 75x + 50x = 20(1200)
Answer:
letter c
Step-by-step explanation:
Answer:
a. |x - 1.5| < 0.125
b. -0.125 < x - 1.5 < 0.125
c. 1.375 < x < 1.625
d. Bolt has to be greater than 1.375 inches and less than 1.625 inches to be within the margin of error of 0.125 inches.
e. One acceptable length for a bolt is 1.4 inches.
f. One non-acceptable length for a bold is 1.7 inches.
Step-by-step explanation:
Solve for x:
-0.125 < x - 1.5 < 0.125
-0.125 < x - 1.5 and x - 1.5 < 0.125
1.375 < x x < 1.625
Write this as: 1.375 < x < 1.625

Answer: 100(pi)/9
Step-by-step explanation:
We use the equation (theta/360)(2)(pi)(r)
Theta = 100 (100 degrees of a 360 degree circle)
r = 10 (not 20 because that is the whole needle, we need half of 20 for the radius)
Plugging this in: 100/360 (2)(pi)(10)
2,000(pi)/360
Divide by 20 to simplify:
Answer:
3z+15
Step-by-step explanation:
By using the distributive property of equality you can distribute the 3 into the parenthesis to find that 3 times z is 3z and 3 times 5 is 15 so 3z+15
Answer:
3z+15
