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 yellow flowers to the white flowers?

350:700

Step-by-step explanation:

so you know there are 350 red flowers in a room and There are 70 more yellow flowers than red flowers. so you do 350+70+420= yellow and you know here are 140 fewer white flowers than yellow flowers so you do          420 - 140 = 280 = white so you do 420 + 280= 700 so you get  350:700

true !

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
