Given:
long stick: 3 4/5 feet
short stick: 3 1/2 feet
convert mix fractions into improper fractions:
3 4/5 = (3*5)+4/5 = 19/5 long stick
3 1/2 = (3*2)+1/2 = 7/2 short stick
19/5 - 7/2 ⇒ (19/5 * 2/2) - (7/2 * 5/5) = 38/10 - 35/10 = (38 - 35)/10 = 3/10
3/10 feet should be cut from the longer stick so that the two walking sticks will be the same length.
3 4/5 ft = 45.6 inches long stick
3 1/2 ft = 42 inches short stick
3/10 ft = 3.6 inches to be cut from long stick
45.6 inches - 3.6 inches = 42 inches
Answer:
1/2(i think)
Step-by-step explanation:
since a coin has two sides
the denominator would be 2
since the coin has 1 chance of it landing on heads and 1 chance of it landing on 2
the probability the coin will land on heads is 1/2
hope this helps!
Answer: 5
Step-by-step explanation: To find the (GCF) or greatest common factor of 15 and 20, begin by finding all of the factors of 3.
Since 15 ÷ 1 is 15, this means that 1 and 15 are factors.
Since 15 ÷ 3 gives us 5, this means that 3 and 5 are factors.
Also, 15 ÷ 5 and 15 ÷ 15 would be factors, but we don't list repeat factors.
Next, we find all of the factors of 20.
Since 20 ÷ 1 is 20, we know that 20 and 1 are factors.
Since 20 ÷ 2 is 10, we know that 10 and 2 are factors.
Since 20 ÷ 4 is 5, we know that 5 and 4 are factors.
Now we look for the largest factor that is shared by the two lists which is 5.
Therefore, the greatest common factor of 15 and 20 is 5.
The short answer is to solve one equation for one variable, then swap that variable in a different equation.
Example:
2x + 2y = 6
y-x = 1
Step 1: solve either equation for a variable: (#2) y = x+1
Step 2: substitute for your solved variable (I can substitute x+1 for y)
(#1) 2x + 2(x+1) = 6
2x + 2x + 2 = 6
4x + 2 = 6
4x = 4
x = 1
now use x=1 to solve for y in either original equation
