Geometry solve for x​

Mathematics
1 answer:
gulaghasi [49]3 years ago
3 0

Answer: b

Step-by-step explanation: the parallel proportionality theorem states that “if two or more parallel lines are intersected by two transversals, the parallel lines divide the transversals proportionally.” Therefore, you make a ratio and solve:

(4/2)=(6/x) and if you solve, x=3

now, 6+3=9, so 2x-11=9

if you solve for that, x=10

The ratio of girls to boys in a running club was 3:5. There were 15 girls. How many total members were there in total?
AlexFokin [52]

Answer:

40

Step-by-step explanation:

The number of girls is represented by 3 parts of the ratio.

Divide number of girls by 3 to find value of one part of ratio.

\frac{15}{3} = 5 ← value of 1 part of ratio, thus

5 parts = 5 × 5 = 25 ← number of boys

Total members = 15 + 25 = 40
