Answer:
The answer is 4.
Step-by-step explanation:
First you look in the parenthesis (PEMDAS)
Do the exponent first (PEMDAS).
You should end up with (16-8)/2
What you should do next is (8)/2 (PEMDAS)
Your last step leaves you with 4 (PEMDAS)
Answer:
1.12243
2.1111
3.128.33333
4.6000
5.17
Step-by-step explanation:
B: x = 5.5 or -5.5
(square root) -> 2x = 11
(divide by 2) -> x = 5.5 or -5.5
<span>We are going to define two equations where b means bagels and m will be muffins,
First equation: 10*b + 4*m = 13
Second equation: 5*b + 8*m = 14
From the second equation, we can isolate b:
b = (14 - 8*m)/5
In the second equation
10*(14 - 8*m)/5 + 4*m = 13
2*(14 - 8*m) + 4*m = 13
28 - 16*m + 4*m = 13
28 -13 = 16*m - 4*m
15 = 12*m
m = 15/12 = 1.25
Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8
So one bagel costs $0.8 and one muffin $1.25</span>
First step is Add 3 to both sides
hope it helps
