1/4 and 1/15. 1/4 is greater because there is less fourths in a whole than fifteenths.

To know which fraction is greater than another is to first look at the denominator

<u>example</u>
$\frac{1}{5} > \frac{1}{8}$

if u look at the denominator the one with the highest denominator is the smallest and then you look at the numerator to imagine if its closer to the denominator or farther away from the denominator.

Can someone help me find AB and BC

Bond [772]

3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
10x + 20 = 180 [combine like terms]
10x = 160 [subtract 20 from both sides]
x = 16 [divide both sides by 10]

Arc AB measures 3(16) = 48 degrees.

Arc BC measures 2(16) + 5 = 41 degrees.

What are the perimeter and area of a rectangle with a length of 20 in and a width of 15 in

Brilliant_brown [7]

Perimeter is 2 times the length plus 2 times the width.

Area is length times width.

Perimeter = (2 x 20) + (2 x 15) = 40 + 30 = 70 inches.

Area = 20 x 15 = 300 square inches.

{2x+2y=2,2(x+y)=10}A. single solution B. no solution C. infinite solutions

mixer [17]

To find the number of solutions of a system of linear equations you need to identify the slope (m) in each equation:

$y=mx+b$

-If the slope is the same in both lines the system has no solution

-If the slope is different in the lines the system has one solution

-If the equation are the same (incluided the value of b) the system has infinitely many solutions

You have the next equations:

$\begin{gathered} 2x+2y=2 \\ 2(x+y)=10 \end{gathered}$

Write the equations in slope-intercept form y=mx+b (solve for y).

First equation:

$\begin{gathered} 2y=-2x+2 \\ y=-\frac{2}{2}x+\frac{2}{2} \\ \\ y=-x+1 \end{gathered}$

Second equation:

$\begin{gathered} 2x+2y=10 \\ 2y=-2x+10 \\ y=-\frac{2}{2}x+\frac{10}{2} \\ \\ y=-x+5 \end{gathered}$ As the equations have the same slope m = -1, the system has no solution (the line doesn't cross each other)

A car salesman receives $50 for each car sale plus 2% of the purchase price. How much must a car sell for in order for the sales

Kamila [148]

We simply take the amount he needs no earn ($500) subtract what he gets for each sale ($50) and divide with the percentage he gets (2% = 0.02)

500-50 = 450
450/0.02 = 22500

The salesperson has to sell a car for $22500 in order to earn $500 himself

Is this a true or false solution? y = 12x; (3,32)

Elenna [48]

Substitute the x-value and see if you get the corresponding y-value. The corresponding y-value an x-value of 3 in this equation should be

$y = 12(3)$

$y = 36$

Since the coordinate (3,32) does not represent that, it is a false solution
