Answer:
0.69 miles per hour
Step-by-step explanation:
speed =distance/time
speed= 506/723
506/723=0.69
Answer:
16=d-12/14
We simplify the equation to the form, which is simple to understand
16=d-12/14
Simplifying:
16=d-0.857142857143
We move all terms containing d to the left and all other terms to the right.
-1d=-0.857142857143-16
We simplify left and right side of the equation.
-1d=-16.8571428571
We divide both sides of the equation by -01 to get d.
d=16.8571428571
Step-by-step explanation:
Answer:
84%
Step-by-step explanation:
Henry completed a total of 50 questions. From these 50 he predicted 36 were right and this means he also predicted that 14 were wrong (50-36 = 14). From these predictions 5 out of 36 from the ones that he predicted were right were actually wrong and 3 of the 14 questions (14-11 = 3) he predicted were wrong were actually right. Meaning in total he wrongly predicted 8 questions which means he predicted 42 correctly ...
42 / 50 = 0.84 = 84%
Therefore, Henry's prediction accuracy is 84%
Answer: 14,000
...............................
7x + 3y = -12
2x + 5y = 38
5y = -2x + 38
y = -2x/5 + 38/5
7x + 3•(-2x/5+38/5) = -12
29x/5 = -174/5
29x = -174
x = - 6
x=-6
y = -2x/5+38/5
y = -(2/5)(-6)+38/5 = 10
x=-6
y=10
