Answer:
5) 1.5 : 7
Step-by-step explanation:
I think for 4) you need only one ratio, for example
The ratio of lemon to sugar is
1 : 1,5
This is the same lik 2:3, or any other you wrote. So it is enough to write just one ratio.
5) also one ratio is enough, becuse all other are the same.
The ratio of cups od sugar to cups of water is 1.5 : 7.
After this step:
1. 8+x=7 multiply both sides by -1
2. x=-7-8 move the constants to the right
3.x=-7-8 Calculate
4. x=-15
Answer: 9-3x
Step-by-step explanation:
You add like terms
don't look at the 3x for now
positive 7 + positive 2 = 9
there is a negative sign next to 3x
9 goes first so
9 - 3x
