Answer :
Option D: [tex]20 \div 6-4[/tex] is the correct solution to the equation [tex]6(x+4)=20[/tex]
Option E: [tex]\frac{1}{6} (20-24)[/tex] is the correct solution to the equation [tex]6(x+4)=20[/tex]
Option F: [tex](20-24) \div 6[/tex] is the correct solution to the equation [tex]6(x+4)=20[/tex]
Explanation:
The expression is [tex]6(x+4)=20[/tex]
Let us find the value of x.
[tex]\begin{aligned}6(x+4) &=20 \\6 x+24 &=20 \\6 x &=-4 \\x &=-\frac{2}{3}\end{aligned}[/tex]
Now, we shall find the expression that is equivalent to the value [tex]x=-\frac{2}{3}[/tex]
Option A: [tex](20-4) \div 6[/tex]
Simplifying the expression, we have,
[tex]\frac{16}{6}=\frac{8}{3}[/tex]
Since, [tex]\frac{8}{3}[/tex] is not equivalent to [tex]x=-\frac{2}{3}[/tex], the expression [tex](20-4) \div 6[/tex] is not equivalent to the equation [tex]6(x+4)=20[/tex]
Hence, Option A is not the correct answer.
Option B: [tex]16(20-4)[/tex]
Simplifying the expression, we have,
[tex]16(16)=256[/tex]
Since, 256 is not equivalent to [tex]x=-\frac{2}{3}[/tex], the expression [tex]16(20-4)[/tex] is not equivalent to the equation [tex]6(x+4)=20[/tex]
Hence, Option B is not the correct answer.
Option C: [tex]20-6-4[/tex]
Simplifying the expression, we have,
[tex]20-10=10[/tex]
Since, 10 is not equivalent to [tex]x=-\frac{2}{3}[/tex], the expression [tex]20-6-4[/tex] is not equivalent to the equation [tex]6(x+4)=20[/tex]
Hence, Option C is not the correct answer.
Option D: [tex]20 \div 6-4[/tex]
Using PEMDAS and simplifying the expression, we have,
[tex]$\begin{aligned}(20 \div 6)-4 &=\frac{10}{3}-4 \\ &=\frac{10-12}{3} \\ &=-\frac{2}{3} \end{aligned}$[/tex]
Thus, [tex]-\frac{2}{3}[/tex] is equivalent to [tex]x=-\frac{2}{3}[/tex], the expression [tex]20 \div 6-4[/tex] is equivalent to the equation [tex]6(x+4)=20[/tex]
Hence, Option D is the correct answer.
Option E: [tex]\frac{1}{6} (20-24)[/tex]
Simplifying the expression, we have,
[tex]$\begin{aligned} \frac{1}{6}(20-24) &=\frac{1}{6}(-4) \\ &=-\frac{4}{6} \\ &=-\frac{2}{3} \end{aligned}$[/tex]
Thus, [tex]-\frac{2}{3}[/tex] is equivalent to [tex]x=-\frac{2}{3}[/tex], the expression [tex]\frac{1}{6} (20-24)[/tex] is equivalent to the equation [tex]6(x+4)=20[/tex]
Hence, Option E is the correct answer.
Option F: [tex](20-24) \div 6[/tex]
Simplifying the expression, we have,
[tex]$\begin{aligned}(20-24) \div 6 &=-\frac{4}{6} \\ &=-\frac{2}{3} \end{aligned}$[/tex]
Thus, [tex]-\frac{2}{3}[/tex] is equivalent to [tex]x=-\frac{2}{3}[/tex], the expression [tex](20-24) \div 6[/tex] is equivalent to the equation [tex]6(x+4)=20[/tex]
Hence, Option F is the correct answer.
