Solve this equation:
300+5x=450+2x
3x = 150
x = 50
so the answer is 50 books
Answer:
(2/3)r=30
r=45cm
Step-by-step explanation:
When trying to find a fraction of something, multiply to get your answer:
(2/3) of r = (2/3)r
The blue ribbon can be represented by both 30cm and (2/3)r cm:
(2/3)r=30
2r=90
r=45cm
Answer:
False
Step-by-step explanation:
If it is a right triangle, the Pythagorean theorem will apply
a^2 + b^2 = c^2
4^2 + 5.05^2 = 6.6^2
16 +25.5025 =43.56
41.5025=43.56
This is not true so it is not a right triangle
Round to the nearest integer
4^2 + 5^2 = 7^2
16+25 = 49
41 =49
This is not true

slope = (7 - 7)/(5+1) = 0/6 = 0
slope = 0
