Answer: 0.6 in 10 % ; 0.4 in 15 %
Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6

{-1/2, -1/4, 1/2}
Step-by-step explanation:
x > - 1 can be voiced as "x is greater than -1." In other words, any x value greater than -1 satisfies this inequality.
1/2 is greater than -1. 1/2 lies to the right of -1.
-1/2 is greater than -1.
-1/4 is greater than -1.
-5/2 is the same as -2 1/2. This is smaller than -1. Eliminate this choice

Kami went out to eat. She ordered a sandwich and chips. The total was $12.50 including tax. How much will she pay with a 15% tip
Answers
Answer:
Step-by-step explanation:
Hello! So with finding out the total + tax, we just multiply $12.50 by .15 (that is our 15% tip). Then we add that new number to $12.50 and that is the total with the tip! Let's do it,
12.50 * .15 = 1.88
12.50 + 1.88 = $14.38

Step-by-step explanation:
Given that
g(1)= -2
g(2)= 6
g(n)=g(n−2)⋅g(n−1)
Now the g(3) is
g(3) = g(3 - 2) . g(3 - 1)

HELP PLEASE!!! Maia walks 12 miles. Then she walks 1/4 of that distance. select ALL of the expressions that represent the total distance she walks.
Answers
Answer:
1, 2, and 3
Step-by-step explanation:
The expressions that represent the total distance she walked are 12 + 0.5 × 12, 12(1 + 0.5), and 12×1.25.
What is a fraction?A fraction is a part of the whole represented by a/b, where a and b are any integers.
Given that, Maia walks 12 miles and then 1/4 of 12 miles.
The total distance is:
12 + 1/4 of 12
= 12 + 1/4×12
= 12 + 0.5 × 12
=12(1 + 0.5)
= 12×1.25
= 15
Hence, the expressions that represent the total distance she walked are 12 + 0.5 × 12, 12(1 + 0.5), and 12×1.25.
