Which choice gives a valid first step to solve 2(w − 3) = 5? Exclude any choice where the explanation for the step is false.
1 answer:
Answer:
D. Use the Distributive Property. You clear the parentheses and then solve the two-step equation.
Step-by-step explanation:
Given problem;
2(w − 3) = 5
To solve this problem:
Use the distributive property to clear the parentheses;
2w - 6 = 5
Then, collect like terms, add 6 to both sides;
2w = 5 + 6
2w = 11
Now divide both terms by 2
w =

Answer:
Correct answer is:
Step-by-step explanation:
Given that Number of bracelets with yellow beads is represented by
Each bracelet with yellow beads is sold for $5.
Total money raised by bracelets with yellow beads = Number of bracelets sold Money raised by sale of one such bracelet =
Also Given that Number of bracelets with Orange beads is represented by
Each bracelet with orange beads is sold for $6.
Total money raised by bracelets with orange beads = Number of bracelets sold Money raised by sale of one such bracelet =
Given that total money raised by sale of both type of bracelets is $660.
so, the first equation becomes:
It is also given that "<em>The number of bracelets with yellow beads that Sierra sold is 8 more than twice the number of bracelets with orange beads</em>"
So, by equation (1) and (2), the system of equations is:
