Delta Math
Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.

Hi there! Thanks for asking a question here on Brainly.
Step 1: We need to simplify both sides of the equation.
⚫ <span><span><span><span>5a</span>−15</span>+<span>9a</span></span>=<span><span>3a</span>+29
</span></span>⚫ <span><span><span><span><span>5a</span>+</span>−15</span>+<span>9a</span></span>=<span><span>3a</span>+29
</span></span>⚫ <span><span><span>(<span><span>5a</span>+<span>9a</span></span>)</span>+<span>(<span>−15</span>)</span></span>=<span><span>3a</span>+29
</span></span>
Combine like terms
⚫ <span><span><span>14a </span>+<span>15 </span></span>= <span><span>3a </span>+ 29
</span></span>⚫ <span><span><span>14a </span>− 15 </span>= <span><span>3a </span>+ 29
</span></span>Step 2: Subtract 3a from both sides.
⚫<span><span><span><span>14a </span>− 15 </span>− <span>3a </span></span>= <span><span><span>3a </span>+ 29 </span>− <span>3a
</span></span></span>⚫<span><span><span>11a </span>− 15 </span>= 29
</span>Step 3: Add 15 to both sides.
⚫ <span><span><span><span>11a </span>− 15 </span>+ 15 </span>= <span>29 + 15
</span></span>⚫ <span><span>11a </span>= 44
</span>Step 4: Divide both sides by 11.
⚫ 11a11= 4411
a = 4
