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

<span>Hope that helps! ★ <span>If you have further questions about this question or need more help, feel free to comment below or leave me a PM. -UnicornFudge aka Nadia </span></span>

1:Simplify 5a-15+9a to 14a−15
<span>14a-15=3a+29

</span>2:Add <span>15</span> to both sides
14a=3a+29+15

3:Simplify <span>3a+29+15</span> to <span>3a+44</span>
<span>14a=3a+4<span>4

</span></span>4:Subtract <span>3a</span> from both sides
<span><span>14a−3a=44</span>

5:Simplify 14a<span>−3a</span> to 11a
<span>11a=44

6:Divide both sides by 11
<span><span>a=44/11
</span><span>
7:Simplify 44/11 to 4
a=4</span></span></span></span>

Mrs. Allard asked her students to identify which of the polynomials below are in standard form and explain why.
ANEK [815]

Answer:

Only II. is written in standard form

Step-by-step explanation:

The three polynomials given are:

I. 15x^4 - 6x + 3x^2 - 1

II. 12x^3 + 8x + 4

III. 285 + 8x^2 + 10%

A polynomial is said to be in standard form when the variables are written in terms of descending powers i.e. the term with the highest power first, followed by the next and so on.

Examining the three polynomials I, II and III, there is only one which follows this rule and that is:

II. 12x^3 + 8x + 4

The term with the highest power (3) came first, followed by the term with the next degree of power (1) and the last term with degree of power as 0.

Hence, only II. is written in standard form.

A collection of 22 dimes and quarters has a total value of $4.00. Write a system of equations that defines this situation and so
Rainbow [258]
Since dimes + quarters = 22
And dimes are 0.10 cents as quarters = 0.25 cents
Let’s make d = dime, q = quarter
d + q = 22
0.10d + 0.25q = 4.00
Let’s use substitution
d + q = 22, get d or q by itself
d = 22 - q (plug into second equation)
0.10(22-q) + 0.25q = 4
2.2 - 0.10q + 0.25q = 4
2.2 + 0.15q = 4
0.15q = 1.8, q = 12
Since there are 12 quarters you know there are 10 dimes (22 in total)

Solution: 10 dimes, 12 quarters

Is the expression 5y-10 equivalent to 5(y-2
KonstantinChe [14]

Answer:

Yes, they are equivalent.

Step-by-step explanation:

They are equivalent, to see this, simplify the expression.

Distribute into the parenthesis.

5(y)- 5(2)

Then simplify into...

5y-10

This is equivalent to 5y-10

<h2>5y-10 = 5(y-2)</h2>
