Answer:
s=32
Step-by-step explanation:
15x-31 = 9x+11
6x=42
x=7
2(63+11)= 2(74)= 148
180-148=32
1) Jason: Shop A - 11 units; Shop B - 12 units. Sales increase at 17% per week. So, 11 + 12 = 23.
f(x) = 23(1.17)ˣ
2) Daniel: Element A temp - 44(1.13)ˣ ; Element B temp - 17(1.13)ˣ. How much temp of Element A be more than the temp of Element B.
f(x) = 44(1.13)ˣ - 17(1.13)ˣ = 27(1.13)ˣ
f(x) = 27(1.13)ˣ
3) Maggie: Tshirt price - $13. Charity donation - 270
f(x) = 13x - 270
4) Mr. Smith: Length of backyard - 30x + 29 ; Length of square patio - 13x + 6
Length not covered by the patio.
f(x) = (30x + 29) - (13x + 6) = 30x - 13x + 29 - 6 = 17x + 23
f(x) = 17x + 23
Answer:
1/7
Step-by-step explanation:
- I can't really tell what the fraction you have is, I am assuming it is 2/14. If that is correct, simplify by finding a common number.
- Ask yourself, what can both be divided by? (Answer is 2)
- Knowing both simplify by 2, divide the numerator (top) and denominator (bottom) by 2.
- You should get 1/7 (2/2 = 1 and 14/2 = 7)
- If you have any further questions on this topic please let me know. I would be glad to help anytime!
