This is confusing but I think yo umean

times both sides by 7x
x+5+x=441x
2x+5=441x
minus 5 both sides
2x=436
divide both sides by 2
x=218
Answer:
It does because 26 = 20 + 6, and the model shows 2 groups of 10 and 2 groups of 3.
Step-by-step explanation:
Two groups of 10 make 20. Two groups of 3 make 6.
20 + 6 = 26
B is wrong. The model does not show two groups of 6.
C is wrong. The model should show one group of 6..
D is wrong. The model should show two groups of 10 and one group of 6.
Steven:10k=x and Theo:15k=x. Then you subtract Theo's or the highest number by the smallest number, or Steven
If two chords of a circle are congruent, then their intercepted arcs are congruent
7x-39 = 87
7x = 87 + 39
7x = 126
x = 126/7
x = 18
