Answer:
There are 45 library books in the classroom.
Step-by-step explanation:
The problem says that Marvin, Latoya and Abdulla each read 3/7 of the library books in the classroom. If Latoya read 3/7 of the books, we can form a proportion to determine the number of total library books in the classroom.

To solve for 'x', we can either cross-multiply and divide, or we can multiply the denominator by the same factor as the numerator to get a product of 15. In this case, the same factor would be 5, so 7 x 5 = 35. If we cross-multiply:
3x = (15)(7) or x = 35.
Im pretty sure its 3x + 1

Step-by-step explanation:
A landscaper is creating a rectangular flower bed such that the width is half of the length . the area of the flower bed is 34 square feet . write and solve the equation determine the width of the flower bed , to nearest tenth of floor .
Answer :
it says that width is half the length . which also implies that length is double the width . as we shift the 2 from denominator , it gets multiply on RHS
let the length be 2x
and
width be = x
length × breadth = 34
2x × x = 34
2x^2 = 34

x = width = 5.8309518948
