3) Write an expression to represent:
"8 times the sum of 10,
and a number"

Step-by-step explanation:

Given the information

8 times the sum of 10 and a number

Let the number be x

Then, the sum of the number and 10 will give (x+10)

Then, 8 times the sum of 10 and the number will give

8×(x+10)

8(x+10)

Open the bracket

8x+80

Then, the expression is 8x+80

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
