MATHEMATICS

1. If there are 1080 students in the school, how many students are in the class of 27?

2. Solve for [tex]$x$[/tex] in the equation [tex]$3(x-1) = 10(a-1)$[/tex].


Basic Science

1. What is renewable and non-renewable energy? Provide examples.



Answer :

Sure, let's solve the equation [tex]\( 3(x - 1) = 10(a - 1) \)[/tex] for [tex]\( x \)[/tex] step-by-step.

1. Start with the given equation:
[tex]\[ 3(x - 1) = 10(a - 1) \][/tex]

2. Distribute the constants 3 and 10 to the terms inside the parentheses:
[tex]\[ 3x - 3 = 10a - 10 \][/tex]

3. Isolate the term involving [tex]\( x \)[/tex]:
[tex]\[ 3x - 3 = 10a - 10 \][/tex]

4. Add 3 to both sides to move the constant term to the right side:
[tex]\[ 3x = 10a - 10 + 3 \][/tex]

5. Combine the constant terms on the right side:
[tex]\[ 3x = 10a - 7 \][/tex]

6. Divide both sides by 3 to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{10a - 7}{3} \][/tex]

So, the solution for [tex]\( x \)[/tex] in terms of [tex]\( a \)[/tex] is:
[tex]\[ x = \frac{10a}{3} - \frac{7}{3} \][/tex]

Thus, when solved, [tex]\( x \)[/tex] is expressed as:
[tex]\[ x = \frac{10a}{3} - \frac{7}{3} \][/tex]

This provides the value of [tex]\( x \)[/tex] in terms of the variable [tex]\( a \)[/tex].
