A child bus ticket costs $0.40 and an adult’s ticket costs $0.70. A group of 11 individuals pays $5.90 for their fare.
oee [108]
Here we have a system of equation like this:
A+B=11\\
0.4A+0.7B=5.9
from the first equation we get:
A=11-B
Substitute in the second equation we get:
0.4(11-B)+0.7B=5.9\\4.4-0.4B+0.7B=5.9\\0.3B=1.5\\B= \frac{1.5}{0.3}=5
Substitute i the first equation again we get:
A=11-B=11-5=6
We deduce that:
A > B A is bigger than B.

What are ALL the true statements.
ale4655 [162]

Answer:

C, E, F

Step-by-step explanation:

A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.

B is a true statement.

C is true because when angles undergo dilations, their "size" does not change.

D is false because dilations do not increase the measures of angles.

E is false because a triangle that underwent a dilation becomes similar, not congruent.

F is true because of E's reasoning.
