Explanation and show work:
Answer:
28 quarters and 5 dimes
7(Q)+5(D)
7(4)+5(10)
28Q 50D Q=quarters D=dimes
it would be more efficient to do the substitution method bc its faster and easier
Slope = change in y / change in x
= (8 - -3) / (1 - 2) = (8 + 3) / ( 1 - 2)
= 11 / -1
= -11
Slope is negative.

Where did Viet made an error?
The step 1 indicates the original question.
To get to step 2, we have to subtract 4 from both sides of the equation.
However, the above expression is different from Viet's evaluation.
<em>Hence, we can conclude that Viet made an error in step 2</em>
Answer:
A. 2c + 5 = 25
Step-by-step explanation:
You have 25 dollars to spend so that's your end amount.
It costs 2 dollars for ever carnation, so it's 2 times the amount of carnations you get, hence 2c.
And it's 5 dollars for the delivery fee which you just add to 2c.
I hope this makes sense :)
