Explanation
to solve this we need to translate into math terms, so
Step 1
a) let d represents the number of dimes
let n represents the number of nickles
so
re write the expressions
The number of nickels is three more than seven times the number of dimes in other words you have to add 7 to seven times the number of dimes to obtain the number of nickles
hence
therefore , the expression for the number of nickles is
I hope this helps you
I think the answer is A because it I'm right it did double the size.
<span>Let be the length, and be the width.
If the length is 1.6 times the width, then
If the sum of the length and with (in feet) is 130, then

Ten, substituting the value found for in we find
-->
The two equations we set up at the start form a system of linear equations:

Answer:
Catron's error is
"She did not follow order of operations"
Step-by-step explanation:
Catron evaluates the expression (negative 9) (2 and two-fifths)
That expression can be written as below
Catron's error is
"She did not follow order of operations"
The corrected steps are
Step1: Given expression is
Step2: Convert mixed fraction into improper fraction
Step3: Multiplying the terms
Therefore solution
Simplify the following:
8/(1/3)
Multiply the numerator of 8/(1/3) by the reciprocal of the denominator. 8/(1/3) = (8×3)/1:
8×3
8×3 = 24:
Answer: 24
