A bag contains yellow and blue blocks in the ratio 1:3 There are 8 more blue blocks than yellow blocks. (a) How many yellow blocks are there? (b) How many blue blocks are there?

Step-by-step explanation:

A bag contains yellow and blue blocks in the ratio 1:3

Sum of Proportion = 1 + 3 = 4

There are 8 more blue blocks than yellow blocks.

b = y + 8

y = b - 8

(a) How many yellow blocks are there?

For yellow block

= 1/4 × x = ( b - 8)

(b) How many blue blocks are there?

3/4 × x = ( y + 8)

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
