30/54 + 36/54 = 66/54

Step-by-step explanation: Find a common denominator

Here, it looks like we can multiply the 9 × 6 to get 54

Then we divide the original denominator into the common denominator, then multiply the numerator by the quotient to get an equivalent fraction to add.

Starting with the 5/9   54÷9 = 6   The quotient, 6 multiplies by the numerator 5

6 × 5 = 30  That is the new numerator.

30/54 is the equivalent fraction for 5/9

Now 4/6   54÷6 = 9   Multiply this quotient, 9 times the numerator 4

9 × 4 = 36  That is the new numerator

36/54 is the equivalent fraction for 4/6

Add the numerators of the equivalent fractions keep the denominator the same:

30/54 + 36/54 = 66/54

It is possible to simplify this process. 4/6 is equivalent to 2/3 or 6/9

We could add  5/9 + 6/9 to get 11/9

66 and 54 are both divisible by 6, so 66/54 can be simplified to 11/9 or the mixed number 1²/₉

Sara earned money selling pies and cakes. For the cakes, she made a profit of $200 with an expense of $4 per cake. For the pies, she made a profit of $250 with an expense of $5 per pie. She sold the same number of cakes and pies. How many pies did Sara sell if she earned the same total profit for pies and cakes? Write an equation and then solve for x.​

Answers

50 cakes 50 pies

If each cake is $4 each, and makes a profit of 200, all you have to do is 200 divided by 4 (which is 50)
200/4= 50


Do the same for pies: 250 divided by 5 ( which is also 50!)
250/5=50

I WILL GIVE BRAINLY IF RIGHT Malia drew the hexagon below what is the measure of each angle of the hexagon

B. 90 degrees
C. 120 degrees
D. 144 degrees

Answers


A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.

Answer:

120 Degrees

Step-by-step explanation:

A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.
