What is a way to write 11 more than twice x is less than 44

madam [21]

(2x) + 11 < 44

x is multiplied by two because we are looking for twice of x. 11 is added to the 2x because we are looking for eleven more than the sum of twice of x. Since 2x + 11 is less than 44, we use the lesser than ( < ) symbol.

The number of paper clips that Crystal has is 42 divided by the number of paper clips that Gayle has. If

Nikolay [14]

Answer:

The number of paper clips that Crystal has is 3 and the number of paper clips that Gayle has is 14

Step-by-step explanation:

Let

x----> the number of paper clips that Crystal has

y ---> the number of paper clips that Gayle has

we know that

$y=x+11$ ----> equation A

$x=42/y$ ----> equation B

substitute equation A in equation B

$x=\frac{42}{x+11} \\ \\x^{2} +11x=42\\ \\x^{2} +11x-42=0$

Solve the quadratic equation by graphing

The solution is $x=3\ paper\ clips$

see the attached figure

Find the value of y

$y=3+11=14\ paper\ clips$

therefore

The number of paper clips that Crystal has is 3

The number of paper clips that Gayle has is 14

Gino studied 3/4 hour for his test on Monday. He studied another 2/4 hour on Tuesday. How long did he study in all?

dybincka [34]

Gino studied for 5/4 hours in all. To get this, do 3+2 for the numerator and just put 4 as the denominator. (Four just stays the same the denominator is all fours. If you want more details just put it on comments.) Now you have the answer: 5/4 hours.
