Answers:
OQ + QP = OP
OQ = 11
============================================================
Explanation:
The smaller pieces OQ and QP glue together to form the larger segment OP. This is effectively what the Segment Addition Postulate says. This only works if all three points are on the same single line segment.
We know that OP is 17, so QP = 6 adds to the other unknown piece to get 17. The other piece must be 11 units long. Algebraically you could write,
OQ + QP = OP
OQ + 6 = 17
OQ + 6-6 = 17-6 ... subtracting 6 from both sides
OQ = 11
Composite numbers are numbers that aren't prime. Prime numbers are numbers that have only 2 factors; 1 and itself. Composite numbers have more than 2 factors (2+ pairs).
13 = 1 • 13. 13 is prime, not composite.
39 = 1 • 39, 3 • 13. 39 is composite.
Although we've found our composite number, let's keep searching (just in case).
PENDING NUMBERS: 39.
91 = 1 • 91, 7 • 13. 91 is a composite number.
139 = 1 • 139. 139 is prime.
Your two composite numbers are 39 & 91.
I hope this helps!
Every one of the answers is correct except 3.4
4+x=(4/3) x 4 — you multiply both sides by 4 to get rid of the fraction on the left.
4+x=16/3 — then simplify the fraction on the right
x = 1 1/3 — minus 4 from both sides to get x alone
