The expression for the inequality is

D) 7.65+0.49x≤10.00

The number of stamps is x ≤ 4.795

<h3>Given Data</h3>

Let the number of stamps be x

Cost of mailing the package = $7.65

Amount that Keshila has = $10.00

cost per stamp = $0.49

We can use the equation of straight line to model the situation

<em>y = mx +c</em>

<em />

where y = the total amount that Keshila has

            x =  the number of stamps

            c = constant, the cost of mailing the package

Hence we have

7.65+0.49x≤10.00

<h3>Solving For x</h3>

0.49x ≤ 10-7.65

0.49x ≤ 2.35

divide both sides by 0.49

x ≤ 2.35/0.49

x ≤ 4.795

Hello can someone help me please
Nadusha1986 [10]

Add the three different amounts she gets to find the total:

450 + 300 + 500 = 1250 mg total.


1250 is greater than  1200, so yes, she is getting enough.

Jane is planting a mixture of flowers. For every ounce of Marigold seeds she uses 2/5 of an ounce of lupine seeds how many ounce
dusya [7]

Answer:

\frac{5}{2} ounces of marigold seeds.

Step-by-step explanation:

We have been given that Jane uses 2/5 of an ounce of lupine seeds for every ounce of Marigold seeds. We are asked to find the ounces of Marigold seeds, which Jane will use, if she used one ounce of lupine seeds.  

We will use proportions to solve our given problem.  

\frac{\text{Marigold seeds}}{\text{Lupine seeds}}=\frac{1}{\frac{2}{5}}

Let us simplify our proportion as shown below:

\frac{\text{Marigold seeds}}{\text{Lupine seeds}}=\frac{1\cdot 5}{2}

\frac{\text{Marigold seeds}}{\text{Lupine seeds}}=\frac{5}{2}

Since Jane used 1 pounce of lupine seeds, so we will substitute this value in our proportion as:

\frac{\text{Marigold seeds}}{1}=\frac{5}{2}

\text{Marigold seeds}}=\frac{5}{2}

Therefore, Jane will use \frac{5}{2} ounces of marigold seeds, if she used one ounce of lupine seeds.

30 POINTS,NEED HELP ASAP !!!
zaharov [31]

Answer: OPTION A.

Step-by-step explanation:

You can observe that in the figure CDEF the vertices are:

C(-2,-1),\ D(-2,0),\ E(2,2)\ and\ F(2,1)

And in the figure C'D'E'F'  the vertices are:

C'(-8,-4),\ D'(-8,0),\ E'(8,8)\ and\ F'(8,4)

For this case, you can divide any coordinate of any vertex of the figure C'D'E'F' by any coordinate of any vertex of the figure CDEF:

For C'(-8,-4) and C(-2,-1):

\frac{-8}{-2}=4\\\\\frac{-4}{-1}=4

Let's choose another vertex. For E'(8,8) and E(2,2):

\frac{8}{2}=4\\\\\frac{8}{2}=4

You can observe that the coordinates of C' are obtained by multiplying each coordinate of C by 4 and the the coordinates of E' are also obtained by multiplying each coordinate of E by 4.

Therefore, the rule that yields the dilation of the figure CDEF centered at the origin is:

(x, y)→(4x, 4y)
