Both are
indicators of the chemical composition of silicate minerals, magmas and rocks.
Mafic is
used for silicate minerals, magmas and rocks that are composed of heavier
elements, like magnesium, iron, calcium and sodium. They are dark and have high
specific gravities.
<span>Opposite to
the this, felsic silicate minerals, magmas and rocks in their composition have
less from these heavy elements. They are composed from silicon, oxygen,
aluminium and potassium, are light in color and have lower specific gravities.</span>
The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
0.1x + 0.25y = 19.9 and
x + y = 100
Let x = number of dimes
y = number of quarters
After solving the above system of equations by substitution method.
y = 66
x = 34
Thus, the statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66

#SPJ1
16 1/3 is bigger than 1/4
The answers to that problem vary which one came fiat
Answer:
x= -10
Step-by-step explanation:
The equation is y2-y1 over x2 over x1 so
1-(-2) over -9-(x)=3
1+2=3 over -9-(x)
3/-9-x times -9-x = 3 times -9-x
3=3(-9-x)
3=-27-3x
3+27=-3x
30= -3x
-10= 3x
hope it helps man!!! :)
