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
The number -5 would go to the left of a number scale. Typically because all negatives move to the left of zero on the number scale.
x= -623/18
Hope it helps for you,buddy!
The 3rd one
You can factor 3 out of each term in the numerator. And then divide it by the 3 in the denominator.
I guess itz B because with the rest, a number can be added to get exactly 50. Example C. y= 50x. x could be 1 which is still 50 and D. y=50-x and x could be 0 which is still 50 whiles A. y=50 remains 50
