Answer:

x = 7

Step-by-step explanation:

Mrs. Garcia’s students were asked to find 220% of 75. Each of the students had a different method.

ludmilkaskok [199]

Answer:

Colton.

Step-by-step explanation:

Amy: 220% is basically $\frac{220}{100}$ which in decimal form, is 2.20.

Braden: 100% + 100% + 20% = 220%, so it is accurate.

Colton: 100% + 10% + 10% = 120%, not 220%.

Dainielle: 100% of 75 is 75. Dividing the 100% of 75 by 5 makes a 20%. Adding 100% of 75 twice makes 200%. 200% + 20% = 220%, so it is accurate.

Guyssss I’m confuseddddd

rosijanka [135]

Answer:

0 > -5

Step-by-step explanation:

9w - 4w + 6 > 1 + 5w

add the similar variables

5w + 6 > 1 + 5w

subtract 6 from both sides

5w + 6 > 1 + 5w

-6 -6

5w > 5w - 5

simplify

5w > 5w -5

subtract 5 w from both sides

5w > 5w -5

-5w -5w

simplify

= 0 > -5

Jordan and Baylor are baking cookies for the Holidays. Jordan is baking 29 dozen chocolate chip cookies and Baylor is baking 36

Lana71 [14]

Jordan and Baylor are going to have all together 780 cookies

<u>Solution:</u>

Jordan is baking 29 dozen chocolate chip cookies and Baylor is baking 36 dozen sugar cookies.

We have to find how many cookies are they going to have all together?

Now,<em> total number of cookies = cookies made by Jordan + cookies made by Baylor </em>

Total number of cookies = 29 dozens + 36 dozens

Total number of cookies = 65 dozens

Total number of cookies = 65 x 12 per dozen

Total number of cookies = 780

Hence, they altogether have 780 cookies
