There is a 2 in 12 chance of drawing a penny
Step-by-step explanation:
Answer:
First number=x
Second number=x-11
x+x-11+8=71
2x-3=71
2x=74
divide both sides by 2
x=37
first number is 37
second number is x- 11 that is 37-11 which equals to 26
i hope it helps please mark me brainliest . thanks bye.
Step-by-step explanation:
Given that the quantity demanded for a certain brand of portable CD players is 200 units when the unit price is set at $90.
If we set quantity=y and price=x then in point form, we can write above information as (90,200)
Similarly "The quantity demanded for 1,200 units when the unit price is set at $40. " can be written as (40,1200)
Now we can plug both points into two point formula to find the required equation:
plug those points
y-1200=-20(x-40)
y-1200=-20x+800
y=-20x+2000
Hence demand equation is y=-20x+2000
Step 1: Rewrite the equation
-14+6b+7-2B=1+5b
Step 2: Combine like terms
-14+6b+7-2b=1+5b
-7+4b=1+5b
Step 3: To isolate b, first add 7 on both sides
-7+4b=1+5b
+7 +7
_________
4b=8+5b
Step 4: Again, trying to isolate b, subtract 5b on both sides
4b=8+5b
-5b -5b
_______
-b=8
Step 5 (final step): Because the variable cannot be negative for a final answer, multiply each number by -1.
-1(-b=8)
b= -8
Final Answer: b=-8
Hope this helps :)
