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.

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

Answer:

x = - [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

[tex]16^{x}[/tex] = [tex]\frac{1}{64}[/tex] , that is

[tex](4^2)^{x}[/tex] = [tex]\frac{1}{4^3}[/tex]

[tex]4^{2x}[/tex] = [tex]4^{-3}[/tex]

since bases on both sides are equal , both 4 then equate exponents

2x = - 3 ( divide both sides by 2 )

x = - [tex]\frac{3}{2}[/tex]

The algebraic expression is '4d' for the phrase "The product of 4 and the depth of the pool."

Expressing algebraically means to express it concisely yet easily understandable using numbers and letters only. Most of the Mathematical statements are expressed algebraically to make it easily readable and understandable.

Here, we are asked to represent the phrase "The product of 4 and the depth of the pool" algebraically.

The depth of the pool is an unknown quantity. So let it be 'd'.

Then product of two numbers means multiplying them.

We write the above statement as '4  x d' or simply, '4d' ignoring the multiplication symbol in between.

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

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

Answer:

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.

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

Answer:

9.1 = a+4

Step-by-step explanation:

The right side has two different values, variable a, constant 4.

The left side has the constant 9.1.

If both sides are equal, then

a + 4 should equal 9.1

Answer:

9.1 = a+4

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
