Basically, simplifying variables is the same as regular equations (like 5-3=2 and 5x-3x=2x)
So 7x-x is the same as 7x-1x which equals 6x
And -3p+6p is the same thing as -3+6 but with a p. With this in mind, the answer is 3p
Hope this helps

Answer:
21x^2+3x+12
Step-by-step explanation:
"her students to put two spoonfuls of seawater into their containers"
We have then:
(2) * (5) = 10 mililiter
"he gives each of her 22 students a container"
Thus,
(22) * (10) = 220 mililiter
Therefore, they will remain:
(0.4 * 1000) - 220 = 400 - 220 = 180 milliliter
Answer:
There will be left 180 mililiter of seawater after all 22 students have filled their containers
Answer:
153.36g
Step-by-step explanation:
Density is defined as the ratio of mass per unit volume of a material.
Density = Mass/Volume
Given the edge of a cube which is equivalent to its length L to be 6cm.
Density of the cube = 0.71g/cm³
Volume of the cube = L³
Volume = 6³
Volume of the cube = 216cm³
Mass = Density × Volume
Mass of the cube = 0.71×216
Mass of the cube = 153.36grams
