Sarah thinks that the
following expressions are
equivalent:
2x + 3 = x/2+ 3/4
Is she right? If so, prove
that these two expressions
are equivalent. If not, what
error(s) did she make?

Answers

No they are not correct, 3/4 is not equal to 3
No Sarah is not correct. If you replace x with 1, the first equation would equal 5, but the second equation would equal 1. In addition, when she tried to do the inverse operation, she did the inverse operation on the factors, not the operation.

Answers

Answer: 120

120

Step-by-step explanation:

I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)

P/w = part/whole = ?/400

%/100= percent/100 = 30%/100

These numbers are equivalent

If you don’t understand the top then here is how to do the work-

400x30=12000

12000/100=120

Therefore it’s 120

solve for r: q = p(r + s)

Answers

Answer:

[tex]r=\frac{q-ps}{p}[/tex]

General Formulas and Concepts:

Order of Operations: BPEMDASEquality PropertiesDistributive Property

Step-by-step explanation:

Step 1: Define equation

[tex]q=p(r+s)[/tex]

Step 2: Solve for r

Distribute p:                              [tex]q=pr+ps[/tex]Subtract ps on both sides:       [tex]q-ps=pr[/tex]Divide both sides by p:            [tex]\frac{q-ps}{p} =r[/tex]Rewrite:                                     [tex]r=\frac{q-ps}{p}[/tex]

Step-by-step explanation: To solve for r, start by distributing the p

through the parentheses on the left side to get q = pr + ps.

Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.

Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.

Answers

Answer:

Step-by-step explanation:

Given

There are 9 people going on a trip

They purchased coach tickets =$160

first class tickets =$1180

total budget to spend = $4500

Let coach tickets=X

So first class tickets=9-x

160x+1180(9-x)=4500

160+10620-1180x=4500

160x-1180x=4500-10620

-1020x=-6120

X=6120/1020

X=6

So answer

Coach tickets=X=6

First class tickets=(9-x)

Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.

How many loaves of banana bread can she make?

Answers

Answer:

69 loaves

Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)

First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.

So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread

Answer:
70.57 loaves of banana bread
Explaintion:
1,623 ➗ 23 = 70.5652173913043
Rounded: 70.57

Can yall give me 4 examples of rules of exponents with answers pls?

Answers

Answer and Step-by-step explanation:

When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:

[tex]a^{x} * a^{y} = a^{x+y}[/tex]

When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:

[tex]a^{x} / a^{y} = a^{x-y}[/tex]

When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:

[tex](a^{x)^{y} } = a^{xy}[/tex]

When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:

[tex](ab)^{x} = a^{x} b^{x}[/tex]

Answer:

3/4

Step-by-step explanation:

If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in

1/4(x)=y

1/4(3)=y

3/4=y

And the other one is incorrect

1/4(x)=y

1/4(7)=y

In a class of 42 students, 18 students are in the Math Club, 5 students
are in both the Math Club and the Science Club, and 14 are in neither. How many
students are in the Science Club?

Answers

Answer:

15 maybe?

Step-by-step explanation:

42 - 14 = 28

18 - 5 = 13

28 - 13 = 15

subtract the 14 because it says it is in neither.

Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.

Subtract 13 from the 28 because those 13 are in math and wont be in science also.
