Answer:

Any real number.

Step-by-step explanation:

I dunno what you're asking, but Im assuming you need what a equals to.

a+5(2a-1)+3=11a-2\\a+10a-5+3=11a-2\\11a-2=11a-2\\

The answer is any real number.

Solve 5(y - 10) = -5
leonid [27]

Answer:

y = 9

Step-by-step explanation:

Trying to get the variable alone is the main goal in solving these

to get the variable alone here we can divide both sides by 5, which gets us

y - 10 = -1

now we can add 10 to both sides to get  y = 9

Could you please help me with this? It’s a problem from my grandson’s homework.
gulaghasi [49]

SOLUTION

From the question given, the cost of the toy truck is $36.50 before tax.

Now, the store selling the toy truck adds a 6% sales tax. This means

\begin{gathered} 6\%\times36.50 \\ =\frac{6}{100}\times36.50 \\ =\frac{6\times36.50}{100} \\ =\frac{219}{100} \\ =2.19\text{ dollars} \end{gathered}

Now, we will add this $2.19 to the initial cost, we have

2.19+36.50=38.69

This gives $38.69.

Finally we will do a discount of 10%. 10% discount is

\begin{gathered} 10\%\times38.69 \\ \frac{10}{100}\times38.69 \\ =\frac{10\times38.69}{100} \\ =\frac{386.9}{100} \\ =3.869 \end{gathered}

We will then subtract this 3.869 from 38.69, we get

\begin{gathered} 38.69-3.869 \\ =34.821 \end{gathered}

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82

Identify whether each cube root or square root lies between 2 and 3, 4 and 5, or 9 and 10.
leva [86]

Answer:

The cube root and square root are not given, but I'm going to give a chart that might help.

Square roots:

2 = √4

3 = √9

4 = √16

5 = √25

9 = √81

10 = √100

Cube roots:

2 = ^3√8

3 = ^3√27

4 = ^3√64

5 = ^3√125

9 = ^3√729

10 = ^3√1000
