Answer:
p = 21, and q = 30
Step-by-step explanation:
If x is directly proportional to y, then we know:
y = 35x / 60
We can factor 5 out of that, giving us:
y = 7x / 12
We can also find the inverse of that relationship:
y = 7x / 12
12y = 7x
x = 12y / 7
So in the second row, where x = 36:
y = 7 × 36 / 12
y = 7 × 3
y = 21
And in the third row where y = 17.5:
x = 12 × 17.5 / 7
x = 210 / 7
x = 30
So p = 21, and q = 30
Answer:
Well going with the answer mathematically, it would take 2.5 hours for 2 people to cut the grass.
4.6 moles in 187 grams of magnesium oxide (mgo).
<h3>What is mole explain with example?</h3>
- One mole is defined as the amount of substance containing as many elementary entities (atoms, molecules, ions, electrons, radicals, etc.) as there are atoms in 12 grams of carbon - 12(6. 023×1023).
- The mass of one mole of a substance equals to its relative molecular mass expressed in grams.
- The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula.
- Moles are units used to measure substance amount. Chemistry (Single Science) Atomic structure.
To solve ,
number of moles is equals to the mass in grams divided by RFM
RFM=16+24.3=40.3
=187/40.3
=4.6 moles of MgO

The factorize pf 20 is 10
Answer:
n=0
Step-by-step explanation:
-10n + 24 + 24n = -6n + 24 is the equation you are given
The first thing I did was combine like terms (-10n and 24n)
I should look like this... 14n+24=-6n+24
The second thing I did was add the 6n to 14n. Remember when you switch the sides of a number/letter in an equation the sign in front of it needs to change.
It should look like this... 20n+24=24
The third thing I did was take 24 and 24 and subtract them. You will get 0.
It should look like this... 20n=0
The last thing to do is divide 0 and 20. That will equal 0!
It should look like this... n=0
