Answer:
23
Step-by-step explanation:
2a/3 + 13 where a = 15
Step 1. Substitute a for 15
2(15)/3 + 13
Step 2. Multiply
30/3 + 13
Step 3. Divide
10 + 13
Step 4. Add

Answer:
x = 16
Step-by-step explanation:
Will use sum of angles = 180 theorem.
Vertical angles makes the one across from 60 also 60.
180-124=56
60+56+4x=180
Simplify to get:
4x=64
x=16
Answer:
Step-by-step explanation:
You should have specified that this is simple interest.
I=P(r/12)t
r=(12I)/(Pt)
r=(12(40))/(500(16))
r=0.06
r=6%
Part A
1 day = 1/4 hours of practice
7 days = 7/4 hours of practice (multiply both sides by 7)
1 week = 7/4 hours of practice
1 week = (4+3)/4 hours of practice
1 week = (4+3)/4 hours of practice
1 week = (4/4)+(3/4) hours of practice
1 week = 1+(3/4) hours of practice
1 week = 1 & 3/4 hours of practice
side note: 1 & 3/4 = 1.75
=======================================
Part B
Take the result from part A, and multiply it with 60
So we'll have 60 times 1&3/4 on the left side on the first line, then 60*(1+3/4) on the right side of this same line.
The rest of the lines look like this
(60*1) + (60*3/4)
60 + 60*3/4
60 + 180/4
60 + 45
