Answer:
D: 10x + 5y
Step-by-step explanation:
If we substituted the x and y values in all of these equations, these are the equations and sums we would get:
A: 18 + 54 = 72
B: 30 + 90 = 120
C: 36 + 81 = 117
D: 60 + 45 = 105
Because we now know all of the sums for these equations, we can rule out A, B, and C because they don't have the correct answer that we got when we evaluated the expression which was 105. The only possible option would be D.
(sorry if this is confusing)
Answer:there would be 2247474.75
Step-by-step explanation:
8 900 000/3.96
The McLean family could drive 220 miles in four hours.
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
Answer:
<u>5/4</u>
Step-by-step explanation:
Given :
- tanθ = 3/4 = opposite/adjacent
Finding the missing side :
- The hypotenuse must be found
- √3² + 4²
- √25
- 5
Taking the sec ratio :
- secθ = hypotenuse/opposite
- secθ = <u>5/4</u>
