G:$2.99
R:$16.99

For every 1R we have 3G.
1R+3G=$16.99+3($2.99)
So 1R+3G=$25.96

If we take $129.80÷$25.96, we get 5.
So let's try 5.

5R+15G=5($16.99)+15($2.99)
So 5R+15G=$129.80

Len [333]

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.

Let the total number employees be e.

Three fourth of the total employees is \frac{3}{4}e, the total number of employees at the meeting were less than 24.

\frac{3}{4}e

Multiply 4 both sides.

\frac{3}{4}e\times 4

3e

Divide both sides by 3.

e

Therefore the value of e is less than 32.

In a number line as we approach towards left the the value of integers decreases.

Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.

Since 32 is not included in the solution set, therefore there is an open circle on 32.

Option 4 is correct.

. Shanice is making a garden. The area of the garden is 24 ft2. Use the following shape and information to find the base (6−4) a
crimeas [40]

Answer:

The base and height  of the garden are 4.60 ft and 5.60 ft.

Step-by-step explanation:

The area of the garden is, <em>A</em> = 24 ft².

The base height of the garden are:

base (<em>b</em>) = 6x - 4

height (<em>h</em>) = x + 3

Compute the value of <em>x</em> as follows:

A=\frac{1}{2}\times b \times h\\\\24=\frac{1}{2}\times (6x-4) \times (x+3)\\\\48=6x^{2}+18x-4x-12\\\\6x^{2}+14x-60=0\\\\3x^{2}+7x-30=0\\

The last equation is a quadratic equation.

Compute the roots of the quadratic equation as follows:

x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }\\x = \frac{ -14 \pm \sqrt{14^2 - 4(3)(-30)}}{ 2(3) }\\x = \frac{ -14 \pm \sqrt{556}}{ 6 }\\x = \frac{ -14 }{ 6 } \pm \frac{2\sqrt{139}\, }{ 6 }\\x = -\frac{ 7}{  3 } \pm \frac{ \sqrt{139}\, }{  3 }\\x = 1.59661\\x\approx 1.60

The value of base and height are:

\text{base}=6x-4=(6\times 1.60)-4=5.60\ \text{ft}\\\\\text{height}=x+3=1.60+3=4.60\ \text{ft}

Thus, the base and height  of the garden are 4.60 ft and 5.60 ft.
