Which expression is equivalent to 32 + 16?8(4 + 2)
8(24 + 8)
7(4 + 2)
7(24 + 8)

Answers

Hi there! We know that 32+16=48 so all we have to do is find a expression that equals 48. 8(4+2)=48. 8(24+8)=256. 7(4+2)=42. 7(24+8)=224. Therefore, the expression that is equivalent to 32+16 is 8(4+2).

The answer is the first expression 8(4 + 2 )


32 + 16 = 48 and so does the first expression

A.
function
B.
not a function

Answers

A) A
B) A
C)A
D) B
Reason I know this is because if we look at the x number in all of these, if 2 are the same (like 2,6 and 2,4) then its a non function.
But if none of the x =the same value its a function.
Same goes for B

and now D, is a non function because out X's:
3
5
5
7
5 was repeated so it's a nonfunction.
Got it?

there are 350 red flowers in a room. There are 70 more yellow flowers than red flowers. There are 140 fewer white flowers than yellow flowers. What is the ratio of the number of red flowers to the number of the yellow flowers to the white flowers?

red=350
yellow= 350+70=420
white=420-140=280
ratio of red to yellow to white= 350/420/280 or 35/42/28

Answers

16:24
24:36

Those are possible answers but to solve it you just multiply each side by any number
ok so 8:12 can be 8 to 12, or 8\12
