Answer:
1. 2x + 3y =22
y=4
C. (5,4)
2. y=0
-5x - 2y = -15
B. (3,0)
Step-by-step explanation:
2x+(3)(4)=22
Step 1: Simplify both sides of the equation.
2x+12=22
Step 2: Subtract 12 from both sides.
2x+12−12=22−12
2x=10
Step 3: Divide both sides by 2.
2x/2 = 10/2
x=5
====================================================================
−5x−(2)(0)=−15
Step 1: Simplify both sides of the equation.
−5x−(2)(0)=−15
−5x+0=−15
(−5x)+(0)=−15(Combine Like Terms)
−5x=−15
−5x=−15
Step 2: Divide both sides by -5.
−5x/−5 = −15/−5
x=3
Answer:
Given:
- Sale prices at the Ajax Outlet Store are 50% below the original prices.
- On Saturdays, an additional discount of 20% off the sale price is given.
To find:
- The Saturday price of a coat whose original price is $180.
The formula used to calculate the percentage is (value/total value)*100%.
Step-by-step explanation:
Step 1 of 2
The original price of coat = $180
Ajax always sells at 50% discount
So their sale price = $90
Step 2 of 2
On Saturdays they sell 20% less
Which implies-
1/5*90 = 18
90-18=72
They sell at $72 on Saturday.
Answer:
144 ways
Step-by-step explanation:
Number of paintings = 7
Renaissance = 4
Baroque = 3
We are hanging from left to right and we will first hang Renaissance painting before baroque painting.
For Renaissance we have 4! Ways of doing so. 4 x3x2x1 = 24
For baroque we have 3! Ways of doing so. 3x2x1 = 6
We have 4!ways x 3!ways
= (4x3x2x1) * (3x2x1) ways
= 144 ways
Therefore we have 144 ways to hang the painting.
