Answer:
a=−b−c−d+15
Step-by-step explanation:
Step 1: Add -b to both sides.
a+b+c+d+−b=15+−b
a+c+d=−b+15
Step 2: Add -c to both sides.
a+c+d+−c=−b+15+−c
a+d=−b−c+15Step 3: Add -d to both sides.
a+d+−d=−b−c+15+−d
a=−b−c−d+15
Answer:
66
Step-by-step explanation:
Answer:
Step-by-step explanation:
e = earrings and b = bracelets
so each earring cost 5 bucks.....5e
and each bracelet cost 7 bucks.....7b
and she hopes to make $ 300...
so ur equation is : 5e + 7b = 300 <===
Answer:

Step-by-step explanation:





Simplifying the expression.



Multiplying both sides by x.

Point-slope form: y - y1 = m(x - x1)
(x1, y1) = a coordinate
m = slope
Now, substitute with the given information.
y - 1 = 1/6(x + 7)
