Me rn i will mark the best answers brainleast and mark 5 answer the ones u know n explaintion needed

For the first question, the answer is 25/14.

Because 14x = 25y    Which means x must equal more than y. And 25/14 is the only answer like this.

For the second question, the answer is 30 x 18.

30/5 = 6     18/3 = 6      18 + 18 + 30 + 30 = 96

So, both the perimeter and the ratio is correct with this answer.

For the third question, the first answer is correct.

x < -4    and only a negative number can be less than another negative. Also, the negative must have a higher value to be less than another negative.

For the last question, the last answer is correct. no explanation for this one, it would take too long ;)

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
