With what you've jus given me, no. is there an equation or something to go along with this question?
-6 and 4.5
So to do this you’ll make an equation x will represent the number so 4x^2+6x=108 so we want the equation to equal 0 so we can solve it to do that you have to subtract 108 from both sides so it ends up being 4x^2+6x-108=0 we want to isolate the x onto one side and division property allows us to divide both sides by 2 the reason it’s two is because 2 is the biggest divisible number that every number in the equation is divisible by so once you divide every number by two you get 2x^2+3x-54=0 now you have to factor cause but since you only have 3x and nothing else to factor with you have to write 3x as a difference so you could do 2x^2+12x-9x-54=0 so you are complicating the problem so you can factor out 2x from the expression so 2x(x+6)- 9(x+6)=0 the 54 got factored because it’s divisible by 9 that 6 is in replace of the 54 cause if you solved it 9x6 is still 54 next factor out x+6 so (x+6) x (2x-9) =0 so one of the two have to equal 0 so right the equations separately x+6=0 minus 6 from both sides and you’ll get x to equal -6 and 2x-9=0 add 9 to both sides and you’ll get 2x=9 divide both sides by 9 and you’ll get x to equal 4.5 when you plug 4.5 and -6 for x the equation works out

<em>The question doesn't have any requirement. I'll calculate the water Halle has left for lunch after drinking the rest.</em>
Answer:
<em>Halle has 250 ml of water for lunch</em>
Step-by-step explanation:
<u>Fractions and Proportions
</u>
Fractions often express ratios between partial and total measures. In this context, 1/4 means 1 part out of 4 parts.
Halle goes to school with 1 liter of water in a bottle, she drinks 1/4 of the bottle before school starts. The bottle now has 3/4 of a liter of water
Halle drinks 2/3 of it before lunch, it means that the bottle has 1/3 of 3/4 left of the water. Since 1/3*3/4 = 1/4. That is the fraction of water still present in the bottle.
Since 1 liter is 1000 ml, Halle has 1/4*1000= 250 ml of water for lunch
