Not really sure to this question but I think 2+
Answer:
z=-13/7
Step-by-step explanation:
1. Add 3z(7z+5=-8)
2. Subtract 5(7z=-13)
3. Divide 7(z=-13/7)
Answer:
-39
Step-by-step explanation:
a=-6 b=5 c=-2
a3-b+4c2
(-6)3-(5)+4(-2)2
David will finish first, because if you divide Brad's miles by 2 to his miles in a 1/4 of an hour are 5.95 miles. This means David went 6.2 miles in the same time that Brad went 5.95. Therefore, David will finish first.
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>
