Remember that calculators are not permitted on the TEAS math test, so make sure you are able to subtract large numbers without using a calculator. (subtraction by regrouping)
First divide both sides by 3: 3(x − 4) = 18 x − 4 = 18/3 x − 4 = 6 Then solve for x: x − 4 = 6 x = 6 + 4 x = 10
The above graph is known as a scatterplot, which is a plot of points on x and y axes. In this case, each point would have an x value equal to the temperature in degrees Celsius, and a y value equal to the amount of money in dollars.
The “FOIL method” is the easiest way to remember how to multiply two-termed expressions. Multiply the First two terms, then the Outer two terms, then the Inner two terms, and then the Last two terms, then sum all four to arrive at the answer: 15×2 + 10x − 3x − 2 = 15×2 + 7x − 2
Because Timmy is interrupted during each hour, he can only make four paper airplanes per hour, multiplied by 3 hours, for a total of 12 airplanes. John makes seven paper airplanes during the two hours he works without chores, for a total of 14 airplanes. 14 airplanes minus 12 airplanes equals 2.
Given that it took 5 hours to travel 360km, we can set up a ratio equation to figure out how far the car will travel in 9 hours. 360/5 = x/9 72 = x/9 72*9 = x x = 648
Plug in °C = 30 into the given formula and solve for °F: °F = (°C * 9/5) + 32 °F = (30 * 9/5) + 32 °F = 54 + 32 °F = 86
The sample indicates that 5 out of every 300 randomly selected toys will be faulty. Consequently, a proportion can be set up that relates the unknown number of faulty toys in the total number of toys to the ratio of faulty toys to the sample. Stated otherwise: T is the unknown number of faulty toys in the total. Multiply both sides by 15,000 and then divide the left hand side by 300 to solve for T:
Three comics at $2.65 would equal a total of $7.95. The change would equal $20 − $7.95 = $12.05.
Interest is calculated as follows: $10,000 x 0.07 rate equals $700.
A ton weighs 2,000 pounds. 4 tons hence equal 8,000 pounds.
By taking the second figure and subtracting it from the original/first number (3.68-3.2=0.48) and dividing the result by the original number (0.48/3.20=0.15=15%), you can determine the percentage increase.
Since 15 apples are three times as many as 5, their price is 3x$2 = $6.
If 4 individuals are needed for 2 days, 8 people are needed for 1 day.
There are 24 hours between 7:45 am today and 7:45 am tomorrow. Tomorrow from 7:45 am to 3:15 pm is a span of 7 and a half hours. 31 1/2 hours total
30 gallons multiplied by 3/5 equals 18.
250 miles / (50 mph per hour) equals five hours.
$20 – $16.65 = $3.35
$5.40/12 = $0.45
40 divided by.08 is 500
4 cubed equals 64 (4 x 4 x 4).
