General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
3x - 8 - 12x = 42
Step 2: Solve for x
Combine like terms: -9x - 8 = 42Isolate x term: -9x = 50Isolate x: x = -50/9Can someone help pls?
Answer:
Step-by-step explanation:
Let the original width be x
Then the original length = x + 11
Area = x * (x + 11)
If you decrease each side by 7 you get
Area 1 = (x - 7)(x + 4)
So area - area1 =
x (x + 11) -98 = (x - 7)(x + 4) Remove the brackets
x^2 + 11x - 98 = x^2 - 7x + 4x - 28 Combine the like terms
x^2 + 11x - 98 = x^2 - 3x - 28 Add 98 to both sides
x^2 + 11x = x^2 - 3x + 70 Cancel the x^2
11x = -3x + 70 Add 3x to both sides
14x = 70 Divide by 14
x = 70 / 14
x = 5
=====================
Original conditions
Answer width = 5
Length = 16

A sporting goods store bought a ski set at a cost of $432. Later, the ski set was marked down 10% from its selling price and then marked down another 20%. The total markdown is the greatest possible markdown without the store losing money. Find the original selling price.
Answer:
The original selling price of the ski set is $600
Step-by-step explanation:
The cost price of the ski set = $432
The first percentage mark down of the ski set = 10% from its selling price
The first percentage mark down of the ski set = 20% from its selling price
Let x represent the original selling price of the ski set at the sporting goods store, we are given;
80/100 × (90/100 × x) = The cost price of the ski set
Therefore, we have;
80/100 × (90/100 × x) = 432
0.72 × x = 432
x = 432/0.72 = 600
Therefore, the original selling price of the ski set, x = $600
When flipping a coin, the probability of getting tails is 50% and heads 50%. What is the probability of getting heads
or tails?
50%
60%
75%
100%
Answer:
50%
Step-by-step explanation:
Most people assume the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails
Answer:
100%
Step-by-step explanation:
There is a 50% chance of getting heads, and 50% chance of getting tails.
If these two options are added together, you get 100%. There are only two options on a coin flip anyways, so the probability of getting heads or tails would be 100%.

A car covers a distance of 600 m in 2 minutes whereas a train covers a distance of 75 km in 50 minutes. Find the ratio of their speed.
answer
1:5
Step-by-step explanation:
To find speed use the formula
speed=distance/time
The car's speed is 600m ÷2mins(120secs)
(600÷120)
5m/s
The trains speed will be
speed=distance/time
=75÷50mins(5/6hrs)
=90km/hr
Ratio of their speed should be
first change the speed of the car 5 m/s to km/hr. 5×18/5 = 18km/hr
the speed of the train is 90km/hr
18:90 simplified it will be 1:5

The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was $1,500? If you get stuck, consider using diagrams or a table to organize your work.
Answer:
After one year, the car will be worth $1,275.
Step-by-step explanation:
We know that a new car value decreases by 15% every year. So, we first need to find 15% of $1,500.
1,500 x 0.15 = $225.
Now, me must subtract $225 from the initial value, or $1,500.
1,500 - 225 = $1,275
Therefore, after one year, the car will be worth $1,275.
