monthly earnings= $3680
22% of the earnings is
=22/100*3680
=0.22*3680
=$809.6
Jose's take home will be
3680-809.6
=$2870.4
Y=6x, 2x+3y=-20
Substitution means just plugging in another equation equal to a single variable in order to solve for the other variable, and then the first. In this case, the equation being plugged in is y=6x, so 6x will be put in place of y in the equation 2x+3y=-20.
2x+3(6x)=-20
2x+18x=-20
20x=-20
x=-1
And then x=-1 can be plugged into the original equation to find y. (And, if you wish, into the y= equation to check it.)
2(-1)+3y=-20
-2+3y=-20
3y=-20+2
3y=-18
y=-6
And to check it, we plug the two into the original y= equation.
y=6x
-6=6(-1)
-6=-6
They are equal, so both check out.
x=-1, y=-6

Because C is the
centroid, therefore:
Segments PZ = ZR;
RY = YQ; QX = XP<span>
<span>A.
If CY = 10, then </span></span>
PC = 2*CY = 20<span>
PY = PC + CY = 20 + 10 = 30
Answer: PC = 20</span> PY = 30
B.
If QC = 10, then
ZC = QC/2 = 5<span>
ZQ = ZC + QC = 5 + 10 = 15
Answer: ZC = 5</span> ZQ = 15
<span>C.
<span>If PX = 20
Because the median RX bisects side PQ, therefore PX = QX = 20
PQ = PX + QX = 40
Answer: <span>PQ = 40</span></span></span>
