Answer:

5/12, 6/13, 13/28, 10/17, 2/3

Step-by-step explanation:

First, simplify the ones that could be simplified.

2/3, 5 to 12, 6:13, 10:17, 13/28

(okay apparently only the first could be simplified)

You can look at all of them as fractions

2/3, 5/12, 6/13, 10/17, 13/28

The perimeter of the rectangle is 76 units. Find the length of side pq

larisa [96]

Answer: $PQ=16\ units$

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle is:

$P=2l+2w$

Where "l" is the lenght and "w" is the width.

You can identify in the figure that:

$w=SR=PQ=2z+2\\\\l=QR=PS=3z+1$

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

$76=2(3z+1)+2(2z+2)$

Now you must simplify and solve for "z"

$76=6z+2+4z+4\\\\76-6=10z\\\\70=10z\\\\\frac{70}{10}=z\\\\z=7$

Finally, substituting the value of "z" into $PQ=2z+2$ , you get:

$PQ=2(7)+2=16\ units$

Please help me 8th grade math

Answer:

y=1/2x+6

Step-by-step explanation:

for the equation you start with finding the rate of change (wich is what y changes by as x 9minths) in creases by 1) and then add the Y-intercept, so it would be Y=1/2x+6

Formula:

Y=△y•x+b(y-int)

To find y intercept find what y is when x is 0, or in this case you know it comes out 6 feet tall, so that is what the Y int. is

Rodolfo earns $30.00 in 5 days. Max earns $10.00 more than Rodolfo in 5 days. How much is the Max salary in 8 days?

sertanlavr [38]

Answer: Mac made $64
Rodolfo earns $30 in 5, 30 divided by 5 equals 6. Max made $10 more so 40 divided by 5 equals 8. Since we are trying to find how much Max made in 8 days we multiply 8 by 8 and get 64.
