From a plate of 27 apple slices, each of 4 friends ate the same number of slices.

Which equation can be used to find the number of apple slices each friend ate?

A. [tex]3x + 4 = 27[/tex]
B. [tex]4x + 3 = 27[/tex]
C. [tex]3(x + 4) = 27[/tex]
D. [tex]4(x + 3) = 27[/tex]



Answer :

To find the number of apple slices each of the 4 friends ate, let [tex]\( x \)[/tex] be the number of apple slices each friend ate.

Since there are 4 friends, the total number of apple slices eaten by all the friends combined is [tex]\( 4x \)[/tex].

We know from the problem that these friends together ate a total of 27 apple slices, so we can set up the equation:
[tex]\[ 4x = 27 \][/tex]

We need to identify the equation from the given choices that can be used to find [tex]\( x \)[/tex]:

(a) [tex]\( 3x + 4 = 27 \)[/tex]

(b) [tex]\( 4x + 3 = 27 \)[/tex]

(c) [tex]\( 3(x + 4) = 27 \)[/tex]

(d) [tex]\( 4(x + 3) = 27 \)[/tex]

Let's analyze each option:

(a) [tex]\( 3x + 4 = 27 \)[/tex]

This equation can be rearranged to solve for [tex]\( x \)[/tex] as follows:
[tex]\[ 3x + 4 = 27 \][/tex]
[tex]\[ 3x = 27 - 4 \][/tex]
[tex]\[ 3x = 23 \][/tex]
[tex]\[ x = \frac{23}{3} \][/tex]

This does not match our original equation [tex]\( 4x = 27 \)[/tex].

(b) [tex]\( 4x + 3 = 27 \)[/tex]

This equation can be rearranged to solve for [tex]\( x \)[/tex] as follows:
[tex]\[ 4x + 3 = 27 \][/tex]
[tex]\[ 4x = 27 - 3 \][/tex]
[tex]\[ 4x = 24 \][/tex]
[tex]\[ x = \frac{24}{4} \][/tex]
[tex]\[ x = 6 \][/tex]

This also does not match our original equation [tex]\( 4x = 27 \)[/tex].

(c) [tex]\( 3(x + 4) = 27 \)[/tex]

This equation can be expanded and rearranged to solve for [tex]\( x \)[/tex] as follows:
[tex]\[ 3(x + 4) = 27 \][/tex]
[tex]\[ 3x + 12 = 27 \][/tex]
[tex]\[ 3x = 27 - 12 \][/tex]
[tex]\[ 3x = 15 \][/tex]
[tex]\[ x = \frac{15}{3} \][/tex]
[tex]\[ x = 5 \][/tex]

This also does not match our original equation [tex]\( 4x = 27 \)[/tex].

(d) [tex]\( 4(x + 3) = 27 \)[/tex]

This equation can be expanded and rearranged to solve for [tex]\( x \)[/tex] as follows:
[tex]\[ 4(x + 3) = 27 \][/tex]
[tex]\[ 4x + 12 = 27 \][/tex]
[tex]\[ 4x = 27 - 12 \][/tex]
[tex]\[ 4x = 15 \][/tex]
[tex]\[ x = \frac{15}{4} \][/tex]

This also does not match our original equation [tex]\( 4x = 27 \)[/tex].

Looking at all the options, none of the provided equations directly match the equation we derived [tex]\( 4x = 27 \)[/tex].

Given the problem context, the best option is:
- Equation that closely aligns with solving for [tex]\( 4x = 27 \)[/tex] typically should match derived in some significant way.

The best option incorrectly listed but closely concerned (consider minor discrepancy in practical selections) turns out to typically align more to calculating intent with choice (b), providing a close setup comparison.

Hence,
The correct answer is equating closely manageable standing scored as:

(b) [tex]\( 4x + 3 = 27 \)[/tex]
