Step-by-step Answer:
There is a total of 10 coins, 5 dimes, 2 quarters and three pennies.
By picking a coin, it could be any that shows up out of the 10, so the probability of picking any coin in particular is 1 / 10.
If there are 5 dimes, the probability of picking ANY one particular dime is 1/10, so with 5, the probability of picking ANY of the five dimes is 5/10 = 1/2.
Going along the same line of thought, the probability of picking any of quarters and pennies would be 2/10+3/10 = 5/10 = 1/2 as well.
Equations:
q + d = 17
0.25q + 0.10d = 3.35$
———————
-0.10( q + d = 17)
-0.10q -0.10d = -1.7
-0.10q -0.10d = -1.7
0.25q + 0.10d = 3.35
Add the equations together
0.15q = 1.65
/0.15 on both sides
q = 11
———————
q + d = 17
11 + d = 17
-11 on both sides
d = 6
———————
0.25q + 0.10d = 3.35
0.25(11) + 0.10(6) = 3.35
2.75 + 0.60 = 3.35
3.35 = 3.35

Answer:
The value of the equation for x is .
Step-by-step explanation:
Consider the provided equation.
We need to solve the equation for x.
Distributive property:
Use the distributive property and solve the above equation.
Add ax and 8 to both the sides.
Simplify the equation.
Take x common.
Now divide both the sides by b+a.
Hence, the value of the equation for x is .
Answer: C is the correct option
Step-by-step explanation:
In four hours, a hiker in a canyon goes from 892 ft to 256 ft above the canyon floor.
From the above information,
Total distance travelled by the hiker in moving from 892 ft to 256 ft above the Canyon is 256 - 892 = -636 ft
Speed = distance travelled/time
The hiker’s vertical speed is total distance travelled vertically divided by the time it takes to travel the vertical distance. It becomes
-636/4 = –159 ft/h
