Answer:
It takes 6 hours for both to reach an equal paid.
Step-by-step explanation:
You have to form an expressions in terms of x where x determine the number of hours :
Option 1,
$(30 + 9x)
Option 2,
$(14x)
Next, you have to compare it since they want to find out how many hours they work until they reach the same amount :
30 + 9x = 14x
30 = 14x - 9x
30 = 5x
5x = 30
x = 30÷5
x = 6
Answer:
area = 2,142
perimeter = 70
Step-by-step explanation:
area = length x width x height
a=18 x 17 x 7
perimeter = all sides added together and assuming it is a rectangle...
p=18 + 18 + 17 + 17
Answer:
m ∠ W is 58.2°
Step-by-step explanation:
Given:
XY = 15
WZ = 22
∠ XZY =25°
To Find:
m ∠ W = ?
Solution:
In right angle triangle Δ XZY, by Sine identity we have
∴ XZ = 35.49
Now in right angle triangle Δ WZX, by tangent identity we have
∴m ∠W =58.2°
The answer would be 3 because 15-4=11, each book is 3.5 pounds
3.5+3.5=7
7+3.5=10.5
