Answer:
Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:
We will use the SAS (SIDE-ANGLE-SIDE) to prove that two triangles are congruent.
Answer:
12 months
Step-by-step explanation:
Set up a formula; 75 + 15x = 255
Now, solve for x, which is number of months.
subtract 75 from both sides.
15x = 180
divide both sides by 15.
x = 12
x is equal to 12 - she would have had to have the subscription for 12 months to spend 255$.
Answer:
6m
Step-by-step explanation:
for every one meter there's 100 cm so 600cm = 6m
Since the maximum budget that Jennifer has is $62.10. You can input P=62.10 so now you can start solving.
Steps: 62.10 = (20+0.5x)+0.15(20+0.5x)
62.10 = 20 + 0.5x + 3 + 0.075x
(Combine "like" terms: so for here you combine x together)
62.10 = 0.575x + 20 +3
62.10 = 0.575x + 23
-23 - 23
39.10 = 0.575x
(Now divide 0.575 on both sides.)
You should end up with:
x = 68
Jennifer can have 68 pages in her book to fit her budget.
