Answer:
She paid $29.29
Step-by-step explanation:
Finding 7% of 25
Y is 7% of 23.2
Solving our equation for Y
Y = P% * X
Y = 7% * 23.2
Converting percent to decimal:
p = 7%/100 = 0.07
Y = 0.07 * 23.2=1.624
Y ≅ 1.62
Finding 18% of 25
Y is 18% of 23.2
Solving our equation for Y
Y = P% * X
Y = 18% * 23.2
Converting percent to decimal:
p = 18%/100 = 0.18
Y = 0.18 * 23.2= 4.176
Y≅4.18
Add sales tax and tip to 25
25+4.18+1.62= 30.8
But since my answers were estimated to a different way, I would say it s best to say it is d.29.29

Answer:
-4 <u>+</u> 2*sqrt(5)
Step-by-step explanation:
2x^2+16x-8=0
Factor out the 2: 2(x^2+8x)-8=0
Add (b/2)^2 = (8/2)^2 = 16
2(x^2+8x+16)-8 = 0 + 2*16
2(x+4)^2=40
(x+4)^2=20
x+4=<u>+</u>sqrt(20)
x=-4<u>+</u>sqrt(20) = -4 <u>+</u> 2*sqrt(5)

Step-by-step explanation:
Answer:
140 = 40 + 10x
Step-by-step explanation:
The watch is 140 in total. He can pay 40 dollars currently. 10x is the amount of payments there are. How much he can pay with each payment (10x) is unknown so that is why there is the variable.
