Answer:

THe answer is C

Step-by-step explanation:

Answer:

x= 2

Step-by-step explanation:

so you add the values given in the brackets and leave X as it is (do this on both sides of the equation.

1. (x + 5)(x+4)= (x+12)(x+1)

2. multiply the parenthesis on both sides or one at a time

so,  [tex]x^{2}[/tex]+5x+4x+20 = [tex]x^{2}[/tex]+12+1x+12

3. cancel like terms which we have [tex]x^{2}[/tex] so remove that.

5x+4x+20=12+1x+12

4. collect like terms.

9x + 20 = 13x + 12

5. move like terms.

9x-13x=12-20 = -4 = -8

6. x= [tex]\frac{-4}{-8}[/tex]  divide both sides by 4 or basically simplify 4 divided by 8

which leaves u with

x= 2

hope this helps x, let me know if u have any questions. photomath is an app that helps too.

Step-by-step explanation:

An expression contains variables which can be represented by using the alphabets like a, b, c, m, x, y, z, etc. We can form different expressions using various numbers and variables. The expression equivalent to x+(-3)+(-2) - 2 is x-7 = 0. The correct option is B.

An expression or also called the algebraic expression is defined as the mathematical statement which contains numbers, variables and an arithmetic operation between them.

In order to factorize or simplify the expression, we should know how to combine the like terms, factor a number, order of operations. The given equation can be simplified as:

x + (-5) -2 = 0

x - 7 = 0

Thus the correct option is B.

Answer:

m∠2= 97

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

180-83=97

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.

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

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

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
