Considering the definition of an equation and the way to solve it, Matthew would need to invite 80 people.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

Being "x" the number of invites, and knowing that:

If cost at either restaurant is the same, the equation in this case is:

Cost restaurant A= Cost restaurant B

250 + 15x= 370 + 13.50x

Solving:

15x + 13.50x= 370 - 250

1.50x= 120

x= 120 ÷ 1.50

x=80

Finally, Matthew would need to invite 80 people.

Mid point of the length segment PQ has endpoints P(-3, 4) and

Q(1, 7) is (1,11/2).

Mid point = {(-3+1)/2, (4+7)/2}

Mid point = (1,11/2)

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.

A line is said to be a bisector when it divides another line into two identical segments. The line will be split at its midpoint by the bisector. A compass and straightedge can be used to determine the midpoint of a line segment. See creating a line segment's perpendicular bisector.

The value of function f when x is (-3) is 9.

To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.

Rewriting the equation

f(x) = -x + 6

Keep the values of x in the above equation

f(x) = - (-3) + 6

Adding the two negative signs, hence, the value will be 3.

f(x) = 3 + 6

Performing addition to find the value of f(x) when value of x is (-3)

f(x) = 9

Therefore, the value of f(x) is 9.

If a coffee machine dispenses 8-ounce cups of coffee automatically. and the amount of coffee may vary by 3% then the least and greatest number of ounces the coffee machine may dispense is 7.76 and 8.24 respectively.

The least and greatest number of ounces the coffee machine may dispense can be calculated by converting the percentage given.

As, 3% = 3 / 100

3% of 8 = 3 / 100 × 8 = 24 / 100 = 0.24

Now by adding and subtracting the calculated value to 8, the least and greatest number of ounces can be determined.

8 - 0.24 = 7.76

8 + 0.24 = 8.24

Hence, the least ounces the coffee machine may dispense is equal to 7.76 and the greatest number of ounces the coffee machine may dispense is calculated to be 8.24 ounces.

Answer:

752 pies will be made form the 2,528 pound pumpkin

Step-by-step explanation:

Here, we want to know the number of pies that will be made from the given number of purée

Firstly, we need to know the number of cups in 2,528-pound pumpkin purée

Mathematically, 1 pound = 1.92 cups

So , 2528 pound will be 2,528/1.92 = 1,316.67 cups

1 3/4 cups is needed to make a pie

So the number of pies that 1,316.67 cups will

make would be;

1316.67 divided by 1 3/4

= 1316.67/1.75 = 752 approximately

Step-by-step explanation:

When 2 angles are supplementary, they add up to 180 degrees.

We are told that angle 1 is 83 and the angle 1 and 2 are supplementary

So, angle 1 and 2 add up to 180, let's subtract 83 from 180 to find measure of angle 2

Answer:

5.7

Step-by-step explanation:

Delta math

In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Hence, the length of u is 5.54 inches.

Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.

u² = s² + t² - 2(s)(t)·cos U

Given that the ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°.

We can find the length of u by using the Cosine rule

u² = s² + t² - 2(s)(t)·cos U

u² = 4.6² + 1.8² - 2(4.6)(1.8)·cos 118

u² = 19.78 + 3.24 - 16.56 x cos U

u² =  19.78 + 3.24 + 7.77

u² = 30.79

u = 5.54

Hence, the length of u is 5.54 inches.

Answer:

[tex]B= \frac{S + 7}{A}[/tex]

Step-by-step explanation:

We are given the following equation:
S = BA - 7

And we want to solve it for B.

This is a literal equation, and to solve these, we need to isolate the variable we are solving for (in this case, B) on one side.

Here's the equation again:
S = BA - 7

We can start by adding 7 to both sides (removes it from the right side).

S = BA - 7

+7        +7

________________

S + 7 = BA

Now, divide both sides by A to isolate B. Remember that we're dividing both S AND 7 by A.

(S + 7) = BA

÷A       ÷A

[tex]\frac{S+7}{A} = B[/tex]

This can be rewritten to be: [tex]B = \frac{S + 7}{A}[/tex]

You can also write it as  [tex]B = \frac{S}{A} +\frac{7}{A }[/tex] if you wish.

3 cookies/bag

Step-by-step explanation:

First of all, let's define a unit rate. A unit rate is a ratio of the amount of one measurement to one unit of another measurement term. Unit rates can be expressed as fractions.

Now, here is something easier for you to remember: the second unit always have to be something with the quantity of 1.

In this case, "3 cookies/bag" shows how there are three cookies per, or in each bag--which means 1 bag. The second unit, which is bag, has the quantity of one.

The distance formula to get the distance of the fly from the corner of the room in meters is 1.985 meter.

Distance formula -

The distance formula is given by the equation -

[tex]d=\sqrt{ (x2-x1)^{2} +(y2-y1)^{2} \\[/tex]

[tex]where , (x_1, x_2)[/tex] and [tex](y_1,y_2)[/tex]  are two given points.

Apply the distance formula to get the distance of the fly from the corner of the room in meters.

Now,

[tex]x_1 ,y_1[/tex] are form the origin,

Given:

[tex](x_2,y_2) =(1.5,1.3)[/tex]

By using the equation ,

[tex]d=\sqrt{ (x2-x1)^{2} +(y2-y1)^{2} \\[/tex]

[tex]\\d = \sqrt[2]{(1.5^{2} -0^{2})+ (1.3^{2}-0^{2} ) }[/tex]

[tex]d=\sqrt{(2.25+1.69)\\\\d=\sqrt{\frac{225}{100} +\frac{169}{100} } \\d=\sqrt{\frac{394}{100} } \\d=\frac{\sqrt{394} }{10} \\\\[/tex]

Root value of 394,

[tex]\sqrt{394}[/tex] = 19.85

[tex]d= \frac{19.85}{10} \\\\d=1.985[/tex] metre.

Therefore, the distance formula to get the distance of the fly from the corner of the room in meters is 1.985
