Answer:
T=4 plz make brainlest answer
Step-by-step explanation:
Monday overall cost 36+5t
Tuesday overall cost 20+9t
36+5t=20+9t
-20 -20
16+5t =9t
-5t -5t
16=4t
t=4
Check
36+5t=20+9t (t=4)
36+20=20+36
It works
Answer:
C. eighteen and thirty two hundredths
Step-by-step explanation:
Answer:
Input: -7
Step-by-step explanation:
We need to make an equation before solving for x, the input.
Output of A: x × 5 - 4 = 5x - 4
Output of B: x × 3 + 8 = 3x + 8
You know that the output of A is three times the output of B:
5x - 4 = 3(3x + 8)
Now that we have an equation, we can work out the value of x.
5x - 4 = 9x + 24
Isolate like terms.
-24 - 4 = 9x - 5x
Evaluate.
4x = -28
Find x.
x = -28 ÷ 4
x = -7
We're looking for C(h), where h is the hundreds of shirts. The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500. Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect. I'll leave it to you to evaluate C(5).
