Answer:
Step-by-step explanation:
Give the expression ax – c = bx + d, we are isolate x i.e we are to make x the subject of the formula.
ax – c = bx + d
Step 1: subtract bx from both sides
ax – c = bx + d
ax-bx = d+c
Step 2: Factor out x in the left hand side of the resulting expression
x(a-b) = d+c
Step 3: Divide both sides by the coefficient of i.e (a-b)


Hence Victoria can justify the step 3 of her work by dividing both sides of the expression in 2 by a-b
The answer to the problem is y^12
Answer:
7040
Step-by-step explanation:
C= 2000
B = 20/100 x 2000 = 400 + 2000 = 2400
A= 10/100 x 2400 = 240+2400= 2640
2000 + 2400 + 2640 = 7040
30 flower pots times 10 seeds in each equals 300 seeds
Answer:
The profit margin for the concert sponsorship is 31.3725 %
Step-by-step explanation:
An arena receives for 1 event = $1700
An arena receives for 12 events = 
An arena receives for 12 events = 20400
The costs for this sponsorship total $14,000
Profit = 20400-14000
Profit =6400
Profit margin =
Profit margin = 
Hence the profit margin for the concert sponsorship is 31.3725 %
