Answer:
18.
Step-by-step explanation:
3 x 4 = 12, 12 times 12 equals 144, 6 - 4 equals 2, and 2 times 2 times 2 is 8, and 144 / 8 = 18.
Here are some fractions.
10/15
4/6
12/18
10/16
16/24
One of these fractions is NOT equivalent to
2/3
a) Which fraction?
b) Work out 1/8 + 3/4
Give your answer in its simplest form.
Answer:
10/16 is not equivalent to ⅔.
⅛+¾=⅞
Step-by-step explanation:
To simplify to simplest form find the GCF for both and divide on each side.
[tex] \frac{10}{15} = \frac{2}{3} [/tex]
the GCF is 5, so you divide the numerator and denominator by 5 to get 2/3.
[tex] \frac{4}{6} = \frac{2}{3} [/tex]
When you divide the numerator and denominator by 2 (GCF) it would be ⅔.
[tex] \frac{12}{18} = \frac{2}{3} [/tex]
when you divide both the numerator and denominator by 6 (GCF) you get ⅔.
[tex] \frac{10}{16} = \frac{5}{8} [/tex]
when you divide the numerator and denominator by 2 (gcf) you get ⅝.
therefore, 10/16 is not equivalent.
[tex] \frac{1}{8} + \frac{3}{4} = [/tex]
Find the LCM
Least Common Multiple is 16.
8: 8, 16
4: 4, 8, 12, 16
[tex] \frac{2}{16} + \frac{12}{16} [/tex]
for ⅛ you multiply the numerator and denominator by 2 to get 2/16. do the same with 3/4 but with 4 to get 12/16
[tex] \frac{2}{16} + \frac{12}{16} = \frac{14}{16} [/tex]
you can simplify by dividinv both sides by 2 to get 7/8.

I owe $8500 on my credit card. The card has a promotional interest rate of 0% for 24 months. To repay the debt, I'm going to pay a fixed amount toward the balance every month. After 12 months, my remaining debt will be $6460. Which of the following equations correctly relates the remaining debt (D) to the number of months (t) I've been making payments? (Select all that apply.)
Question 4 options:
D=6460+170t
D=170t−6460
170t+D=8500
D=−170t+8500
D+6460=8500t
Answer:
170t+D=8500
D=170t−6460
Step-by-step explanation:
Mathematical models are used to explain real life situations.
We can see from the question that the total debt is $8500 while there is interest rate of 0% for 24 months. We are also told that after 12 months, the remaining debt was $6460.
Now, the equations that correctly model the situation are;

Use the simple interest formula to find the interest earned for $347 at 9.63% for 5 years
Answer:
$167.08
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9.63%/100 = 0.0963 per year,
then, solving our equation
I = 347 × 0.0963 × 5 = 167.0805
I = $ 167.08
The simple interest accumulated
on a principal of $ 347.00
at a rate of 9.63% per year
for 5 years is $ 167.08.

The sides
y + 16 = 46y = 30The angles
60° - x = 180° - (80° + 60°)60° - x = 40°x = 60° - 40°x = 20°Question 4The bottom triangle is equilateral, the top triangle is isosceles

Write the equation for a line that is parallel to the line y=-1/3x -4 and passes through the point (3, -1)
Answer:
y = -1/3x
Step-by-step explanation:
Since the line has to be parallel, that means it will have the same slope. So, we use the given point and slop to solve for the new y= mx + b using the equation y - y = m( x - x)
m= -1/3 x = 3 y = -1
y + 1 = -1/3(x - 3)
y + 1 = -1/3x + 1
y = -1/3x

Find the slope-intercept form of the equation of the line which contains the points (-2, 5) and (3, 20).
Answer:
y = 3x - 11
Step-by-step explanation:
First, use the y2-y1/x2-x1 format to find the slope: 20 - 5/3 - (-2)(Note: change 3 - (-2) to 3 + 2 to make it easier for you)
Simplify 15/5.Your slope would be 3/1 or 3.
Now use the slope-intercept format: y = mx + b(Use either the first point or second point, I chose the first)
5 = 3(-2) + b
Multiply 3 and -2, which is -6.Subtract 5 from -6: -6 - 5 = -11Your y-intercept is -11.

Find the values of x and y.
Answer:
x = 67
y = 169
Step-by-step explanation:
We know that (x-1) + 52 + (y-7) = 180 because they're all on the same straight line. We also know that x-1 = 66, because they are alternate interior angles.
Solve for x:
x-1 = 66
x = 67
Now solve for y:
(67-1) + 52 + (y-7) = 180
y = 169
Angle x measures 42•. Find measure of angle y.
