Answers

Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:

x-4y=6

x+4y=12

we see here that elimination would best fit:

x+x+4y-4y=6+12

or:

x=2y-3

7x+3y-81=23

substitute (2y-3) for x.

Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)

Mario start collecting stamps in January and buys 12 stamps each month.Karen starts collecting stamps in July and buys 18 starts each month. how many months after Karen starts collecting stamps will she have the same number of stamps as Mario?

Answers

Answer:

12 months

Step-by-step explanation:

Given that:

Mario:

12 stamps per month

Since January

Karen :

18 stamps per month

Starts on july

Number of stamps collected by Mario till the end of June :

12 * 6 = 72 stamps

For Mario :

72 + 12x

For karen:

18x

Where x is the number of months after karen starts :

Equate both equations

72 + 12x = 18x

72 = 18x - 12x

72 = 6x

x = 72/6

x = 12

After 12 months

Number of months after karen starts, will they have same amount of stamp

Answers

Hello there!

Step-by-step explanation:

If Jack runs 34 miles, and Pranav runs 18 less, this signifies that we need to subtract 18 from Jack's total miles to get his miles ran.

34 - 18 = 16

Pranav ran 16 miles.

Four of the 16 students in Ms. Salas’s class after school are serving detention. The rest of the students are there for tutoring. Using the diagram below, determine the percent of the students in Ms. Salas’s classroom after school who were there for detention.

Choices:

A: 16%
B: 25%
C: 40%
D: 60%

Answers

the answer is b because 4/16 students are in detention. 25% means 1/4. if u break the group of 16 into four groups, there will be four students in each group (4+4+4+4=16) since four students are in detention, one full group will be in detention so 1/4. this is the best i can explain this but if you would like the mathematical proof work it is:
4 divided by 16 = 0.25 which turned into a percent is 25%

Solve the system of equations.
5x - 7y = 58
y = -x + 2
х =
y =

Answers

Answer:

the x and y is 6 and -4 respectively

Step-by-step explanation:

The computation of solving the system of equations is given below:

Given that

5x - 7y = 58

And,

y = -x + 2

Put y value in the first equation

5x - 7(-x + 2) = 58

5x + 7x - 14 = 58

12x = 58 + 14

12x = 72

x = 6

So y = -6 + 2

= -4

Hence, the x and y is 6 and -4 respectively

Find the circumference of the circle.

A: 47,1 in
B: 22 in
C: 10.5 in
D: 35 in

Answers

Answer:

C≈47.12, or 47.1

Step-by-step explanation:

To find the circumference you just use the formula C=2[tex]\pi[/tex]r.

The radius of your circle is 7.5 which is half of 15, now multiply 2[tex]\pi[/tex](7.5) which gives you your answer!

An even easier way to do this is to use the other formula C=d[tex]\pi[/tex],

Just multiply your diameter (which is what was given to you) by pi and you also get your answer!

water flows through a pipe at a rate of 7 cubic meters per month. Express this rate of flow in gallons per minute. Round your answer to the nearest hundredth.

Answers

Answer:

0.04

Step-by-step explanation:

The rate of flow is 0.043 gallons per minute.

How to convert litres to gallons ?

Divide by 0.264 to obtain litres from gallons and multiply by 0.264 to obtain in gallons from litres.

According to the given question

Water flows through a pipe at a rate of 7 cubic meters per month.

We know 1 cubic meter is = 1000 litre

∴ 7 cubic meters per is

= (7 × 1000) litre

= 7000 litre

= (7000 × 0.264) gallons

= 1848 gallons per month

Now 1 month is

= ( 1 × 30 × 24 × 60 ) minutes.

=43200 minutes

So in 43200 minutes 1848 gallons of water flows through that pipe

∴ In a unit minute or per minute it the rate of flow will be

= 1848/43200 gallons per minute

= 0.043 gallons per minute.
