I think the answer would be 5
Answer:
Inequality: 25x + 30 < 155
Step-by-step explanation:
25x is the cost per lesson. 30 is the recital fee. 155 is the total cost. We used the < sign because she has to pay <u>LESS </u>than $155.
Solve...
25x + 30 < 155
Subtract 30 on both sides...
25x < 125
Divide 25 on both sides...
x < 5
<u>THATS NOT YOUR ANSWER YET </u>Always make sure to plug in the answer you got BEFORE inputting it.
Plug in 5 for x...
25 ( 5 ) + 30 < 155
125 + 30 < 155
155 < 155
You know that she wants to spend LESS than $155, when she takes 5 lessons, as shown above, she spends exactly $155, your answer would be 4 because she spends less than $155 when taking 4 classes, but exactly $155 when taking five.
Really hope this helps! :)
Answer:
2c(c - 3)(c - 8)
Step-by-step explanation:
Hello!
Factor:
- 2c³ - 22c² + 48c
- 2c(c² - 11c + 24)
Think: What two numbers multiply to 24, and add up to -11?
Answer: -8 and -3
Split up the -11c into -8c and -3c:
- 2c(c² - 8c - 3c + 24) (factor each pair)
- 2c( c(c - 8) - 3(c - 8))
- 2c(c - 3)(c - 8)
Answer:
x = 14
Step-by-step explanation:
given f(x) = 2(3x - 5) and f(x) = 74 , then equating gives
2(3x - 5) = 74 ( divide both sides by 2 )
3x - 5 = 37 ( add 5 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
