Answer:
Cost is 7c+34.
Step-by-step explanation:
2(c+17) + 5c
=2c+34+5c
=7c+34
C = 180 - A - B
And
C = 180 - (A+B)
Hope I can help you :)
Brainliest answer :)) ?
Uhh the the Nader ic clearing at the back page
The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
0.1x + 0.25y = 19.9 and
x + y = 100
Let x = number of dimes
y = number of quarters
After solving the above system of equations by substitution method.
y = 66
x = 34
Thus, the statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
