Answer:
14
Step-by-step explanation:
hi! so the question is asking what h is when you input -18 for x, right?
inputing in this question means to substitute, meaning that in this equation, -18 will take the place of x!
- let's see what the equation looks like now
- easy as that!
now let's do the math :)
- because of PEMDAS, remember to do the fraction (dividing) first!
we can change that to --> h = 17 - 3
h = 14
let me know if you're still confused!
Answer: 707 km/h
Step-by-step explanation:
let c = speed of current
16.5 + c = speed of sailboat downstream
16.5 - c = speed of sailboat upstream
distance = travel time * speed
﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋
2(16.5 + c) = 5(16.5 - c)
33 + 2c = 82.5 - 5c
7c = 49.5
c = 7.07 km/h
We plug in 14 for x when we set the two equations equal to each other to prove they are equal.
So true LM congruent to MN
Answer:
Area: 24 sq units
Step-by-step explanation:
Area of a rectangle formula:
A = 0.5bh
Given:
b = 6
h = 8
Work:
A = 0.5bh
A = 0.5(6)(8)
A = 3(8)
A = 24
I would think it would be B
