Answer:

No, because the total will be $3.62

Step-by-step explanation:

When we substitute with 3 and 2 shown below

0.35(3)+0.99(2)+0.59 we get 3.62, which is greater than 3 dollars.

Answer:

Alright so the question states that "She can only spend $3."

A sticker costs $0.35

A eraser is $0.99

A pencil costs $0.59

What you are trying to find is Can Linda buy 3 stickers and 2 erasers.

So add the total value of stickers prices. You need to know what's the cost of 3 stickers and 2 erasers

0.35+0.35+0.35= 1.05+0.99+0.99 = 3.03 So she can't. Now can she buy 1 sticker, 1 eraser, and 1 pencil. So is it enough to get 1 of each item?

0.35+0.99+0.59=1.93 Yeah you can.

But is it enough for her to get 3 stickers, 2 erasers and a pencil?

We already know the cost for 3 stickers and 2 erasers is $3.03. All you need to do is add $0.59 to find the total cost. The total cost of 3 stickers and 2 erasers and a pencil is $3.62. So the answer is No, because the total will be $3.62 and her budget is $3 so she will need extra $0.62 to cover the full cost.

Hope this helps

Find two numbers such that one number is 3 less than twice as big as the other number and the two numbers sum to 21.
Hitman42 [59]

Answer:

The two numbers are:

8 and 13

Step-by-step explanation:

a = 2b - 3       Eq. 1

a + b = 21        Eq. 2

Replacing Eq. 1 in Eq. 2:

(2b-3) + b = 21

3b - 3 = 21

3b = 21 + 3

3b = 24

b = 24/3

b = 8

from Eq. 1

a = 2*8 - 3

a = 16 - 3

a = 13

Check:

From Eq. 2:

a + b = 21

13 + 8 = 21

Divide <br> 8x⁴-6x³+2÷2x²+3
arlik [135]

WhenWhen we divide 8x⁴ - 6x³ + 2 by 2x² + 3 The result obtained is 4x² - 3x - 6 remainder 9x + 20

<h3>What is quotient?</h3>

Quotient is the result obtained when division operation is carried out.

For example when 6 is divided by 2, the result obtained is 3. Thus, the quotient is 3

<h3>How to divide 8x⁴ - 6x³ + 2 by 2x² + 3 </h3>

To divide 8x⁴ - 6x³ + 2 by 2x² + 3, we shall apply the long division method. This is illustrated below:

                         <u> </u><u> </u><u>4</u><u>x² </u><u>-</u><u> </u><u>3</u><u>x</u><u> </u><u>-</u><u> </u><u>6</u><u>  </u>      

             <u>2x² + 3 </u>| 8x⁴ - 6x³ + 2

                       <u>  -(8x⁴ + 12x²)</u>

                         -6x³ - 12x² + 2

                        <u> -(-6x³ - 9x) </u>

                        -12x² + 9x + 2

                         <u>-(-12x² - 18)</u>

                          9x + 20            

 

Thus, the result obtained when we divide 8x⁴ - 6x³ + 2 by 2x² + 3 is 4x² - 3x - 6 remainder 9x + 20
