Answer: X * 1 + Y * 3 + Z * 2 = 45

Step-by-step explanation: we will use bananas, apples and mangoes as the unknowns of the equation.

The value that you multiply to the unknowns will be multiplied by the price that corresponds to it.

These 3 products must be added to result in the total value that is 45.

X * 1 + Y * 3 + Z * 2 = 45

PIT_PIT [208]

By definition of circumference, the length of the arc EF (radius: 6 in, central angle: 308°) shown in red is approximately equal to 32.254 inches.

<h3>How to calculate the length of an arc</h3>

The figure presents a circle, the arc of a circle (s), in inches, is equal to the product of the <em>central</em> angle (θ), in radians, and the radius (r), in inches. Please notice that a complete circle has a central angle of 360°.

If we know that θ = 52π/180 and r = 6 inches, then the length of the arc CD is:

s = [(360π/180) - (52π/180)] · (6 in)

s ≈ 32.254 in

By definition of circumference, the length of the arc EF (radius: 6 in, central angle: 308°) shown in red is approximately equal to 32.254 inches.

<h3>Remark</h3>

The statement has typing mistakes, correct form is shown below:

Answer: The required equation is x=(7\times12-34.5)\div8\frac{1}{4}

Maria can cut 6 sections from the remaining rope.


Step-by-step explanation:

The total length of rope = 7 feet

since 1 feet = 12 inches

Therefore, 7 feet=7\times 12=84\ inches

Let x be the number of sections.

Since the instructions are to use 34.5 inches of rope to tie a tarp on top the the tent. Then, the remaining rope should be cut 8 1/4 inch sections to tie tent to stakes in the ground.

then the required equation will be

x=(7\times12-34.5)\div8\frac{1}{4}\\\Rightarrow\ x=(84-34.5)\div \frac{33}{4}\\\Rightarrow\ x=49.5\div8.25\\\Rightarrow\ x=6

So, maria can cut 6 sections.

a group of 19 students want to see the show at the planetarium. Ticket cost $11 for each student who is a member of the planetar
Illusion [34]
X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247

$-2x = $-38

divide -2 by both sides

x=19, meaning that all of the students are members.
