Answer:
79
Step-by-step explanation:
For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
Answer: a system of linear inequations that represents the situation is:
Answer:
They are similar because their corresponding angles are congruent and their corresponding side lengths are proportional.
Step-by-step explanation:
we know that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
Corresponding angles are congruent
because
∠Q≅∠M
∠R≅∠N
∠S≅∠P
Corresponding sides are proportional
because

substitute the given values

----> is true
therefore
They are similar because their corresponding angles are congruent and their corresponding side lengths are proportional.
