24
Step-by-step explanation:
Using 9 as the figure number, Dion's equation tells us there are ...
2(9) +6 = 18 +6 = 24 blocks in figure 9
Let's solve for "r" by bringing them all to one side.
-3r=6-4r
+4r +4r
r=6
So, r is equal to 6.
Answer:
x=13
Step-by-step explanation:
Q is the midpoint of PR
PQ + QR = PR
PQ= QR
PQ+QR = PR
QF + QR = PR
2QR = PR
2*43 = 9x-31
86 = 9x-31
Add 31 to each side
86+31 = 9x-31+31
117 = 9x
Divide each side by 9
117/9 = 9x/9
13 =x
