Solve for x.
X+2 1/4=4 3/4
A.)1 3/4
B.)2 1/4
C.) 2 1/2
D.) 2 3/4

C.) 2 1/2

Step-by-step explanation:

X + 2 1/4 = 4 3/4

Change the fractions to improper fractions .

We have

X + 9/4 = 19/4

Subtract 9/4 from both sides

X + 9/4 - 9/4 = 19/4 - 9/4

X = 19/4 - 9/4

Look for the LCM of the denominators.

The LCM is 4

Divide the LCM by the denominators and multiply the results by the numerators, the lcm becomes the denominator of the results.

That’s

X = 19 - 9 /4

= 10/4

Divide both numerator and denominator by 2

= 5/2

= 2 1/2

C.) 2 1/2

Step-by-step explanation:

X+2 1/4=4 3/4

Subtract 2 1/4 from each side

X+2 1/4  - 2 1/4=4 3/4 - 2 1/4

x = 2 2/4

This simplifies to

x = 2 1/2

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
