how do we add fractions
Answer:
you have to find a common denominator and then add.
Step-by-step explanation:
for example 2/4 + 4/12
you find the common denominator in this case it would be i will use 4 so 2/4 would stay the same and 4/12 would change to 1/3
*make sure to do the same thing to the numerator to so if you are dividing your denominator by 2 also do the numerator
now you have to add
2/4 + 4/12 = 6/12 (the denominator stays the same)
6/12 can be simplified (if you are asked to simplify) so it is 1/6
Find the value of x.
Answer:
50
Step-by-step explanation:
The upper left hand arc is also 130
The lower right hand arc is also x
A circle all the way around from some starting point is 360 degrees.
x + x + 130 + 130 = 360 Equation. Combine like terms.
2x + 260 = 360 Subtract 260 from both sides
2x = 360 - 260
2x = 100 Divide by 2
x = 100/2
x = 50

The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
Answer:
x = 348
Step-by-step explanation:
The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
0.15x + 65 + 0.1x + 28 = 180
0.25x + 93 = 180
0.25x = 180 - 93
0.25x = 87
x = 87/0.25
x = 348

Answer:
774.25
Step-by-step explanation:
8.75 becomes .0875 because it is 8.75%/100%
711.95 x .0875 = 62.295625
add the cost (711.95) and the tax (62.295625)
711.95 + 62.295625 = 774.245625
rounded = 774.25

Answer:
The interest is $1242.734 and the amount is $13242.734.
Step-by-step explanation:
STEP 1: Convert interest rate of 1.5% per month into rate per year.
STEP 2: Convert 210 days into years.
STEP 3: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example P = $12000, i = 18% and t = 0.57534 years, so
STEP 4: Find an amount by using the formula .
Since P = $12000 and I = $1242.734 we have
Admission to the fair is $15 each ride cost $3 micah spent a total of $36 he spent all of his money on rides and admission
Answer:
7
Step-by-step explanation:
Admission cost = $15
Cost per ride = $3
Total amount spent = $36
We can obtain the number of rides thus :
Let number of rides = x
Admission cost + (cost per ride * number of rides) = total amount spent
15 + 3x = 36
3x = 36 - 15
3x = 21
x = 21 / 3
x = 7
Number of rides = 7
