Answer:
There are 8 dimes there.
Step-by-step explanation:
This question is solved used a system of equations.
I am going to say that:
x is the number of nickels.
y is the number of dimes.
19 coins
This means that x + y = 19.
A nickel is worth $0.05. A dime is worth $0.1. The total of these coins is $1.35. So
0.05x + 0.1y = 1.35
How many dimes are there?
We have to find y.
From the first equation: x = 19 - y.
Replacing in the second:
0.05(19 - y) + 0.1y = 1.35
0.95 - 0.05y + 0.1y = 1.35
0.05y = 0.4
y = 0.4/0.05
y = 8
There are 8 dimes there.
Answer:
60(10 -7) - (-26/2)^2 (do the problems in the parenthesis)
60(3) - (-13)^2 ( multiply 60 and 3 and then square -13)
180- 169 (subtract)
11

Step-by-step explanation:
Given : Stephen evaluated 
. His work is shown below.
To find : Which two statements describe the errors Stephen made?
Solution :
Step 1 -
Step 2 - 
Step 3 - 
Step 4 - 
Error is the step as 4 sign is negative.
So correct step is 
Step 5 - 
Error is the step as there is 4 in place of 3.
So correct step is
The step 4 and 5 describe the errors Stephen made.
