According to PEMDAS
Multiplying/dividing comes first when you read the equation from left to right
The amount invested in the account that yields 7% interest is $4000.
The amount invested in the account that yields 12% interest is $1000.
<h3>What are the linear equations that represent the question?</h3>
a + b = 5000 equation 1
0.07a + 0.12b = 400 equation 2
Where:
a = amount invested in the account that yields 7% interest.
b = amount invested in the account that yields 12% interest.
<h3>How much is invested at each rate?</h3>
Multiply equation 1 by 0.07
0.07a + 0.07b = 350 equation 3
Subtract equation 3 from equation 2
0.05b = 50
b = 50 / 0.05
b = 1000
Subtract 1000 from 5000: 5000 - 1000 = 4000

Step-by-step explanation:
b - no:of students on bus
V - " " on van
so the eqtn is
12v+10b=698
14v+2b=244
so when you solve these two eqtns you get
V=9
b=59
3/12 = (3÷3)/(12÷3) = 1/4
Answer: The largest you can't make is 7 cents.
Step-by-step explanation:
Once you get 3 consecutive amounts, you can get all larger ones just by adding 3 cent stamps. So let's see what you can make:
1 no
2 no
3 yes
4 no
5 yes
6 yes
7 no
8 yes, and this will give you 11 14 17 etc
9 yes, and this will give you 12 15 18 etc
10 yes, and this will give you 13 16 19 etc.
