Answer:

27

Step-by-step explanation:

You would turn the equation around, so it is 21+6=27 and checking, 27-21=6

Answer:

x = 27

Step-by-step explanation:

x- 21 = 6

add 21 to both sides:

x = 27

Check your work by substitution:

27 - 21 = 6

6= 6

x = 27

y= -14        x= -1.556

Step-by-step explanation:

graphing calculator is good  

Answer:

Step-by-step explanation:

first you have to get the inequality to a point where you can actually graph it

to do this you have to get the x to the same side of the less than symbol

you do this like any other equation, subtract x from the left and right sides because whatever you do to one side, you do to the other

this leaves you with -y < -x + 4

you have to multiply the entire thing by -1 because y cannot be negative

this gives you y < x - 4, now you can graph it

because x is isolated you just have to graph y < -4 like so

im not the best at explanations, i apologize

Step-by-step explanation:

                    3/4*x+5-(1/4+1/4*x)=0

   3        1  1

 ((—•x)+5)-(—+(—•x))  = 0

3.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

1 + x                   x + 1

—————  =  —————

Answer:

(a) The slope and the y-intercept are 7 and 15

(b) y represents the total number of baskets of berries the workers picked over a period of time

(c) The rate and the initial amounts are 7 baskets/hour and 15 baskets

Step-by-step explanation:

Answer:

A. the slope of the equation is 7 and y-intercept is 15

B. the term "y" represents the total

C. The rate of change is 7x and the initial amount is 15. The rate of change means the "thing" (or variable) that keeps on changing and here it is the 7x. This means that every hour, the workers pick 7 baskets and this number will change based on the hours, which can is represented by the x. The 15 is our initial amount of baskets we had before starting because it is unchanging, it is our initial amount.

Explanation for A & B:

A.  This equation is written in slope-intercept form which is, y=mx+b the slope is represented by the "m" and the y-intercept is represented by the "b". In simpler words, slope=m and y-intercept=b

B. When we take our given amount which is 15 baskets (y) and add it to our slope  (7x) or the amount that changes based on time

we will get our total y, which represents the total amount of baskets

Answer:

x - 5y = 0

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

x + y = 6y ( subtract 6y from both sides )

x - 5y = 0 ← in standard form

Answer: x-5y=0

Step-by-step explanation:

x+y=6y

6y-y

X=5y

X-5y=0

Answer:

Number of free throws = 155,

Number of two-points field goals= 168

Number of two-points field goals= 124

Step-by-step explanation:

Let x,y, and z be the numbers of free throws, two-point field goals and three-point field goals she made.

As she scored a total of 863 points, so

x+2y+3z=863...(i)

As the number of​ two-point field goals  that Rebecca made was 80 less than double the number of​ three-point field goals she made, so

2z-y=80

Or y=2z-80...(ii)

As the number of free throws​ (each worth one​ point) she made was 13 less than the number of​ two-point field goals she made, so

y-x=13

-x= 13-y

-x= 13-(2z-80)

-x= 93-2z

x=2z-93...(iii)

Now, put the values from equation (ii) and (iii) to equation (i), we have

(2z-93)+2(2z-80)+3z=863

2z-93+4z-160+3z=863

9z=863+93+160=1116

z=1116/9=124

From equation (ii)

y=2x124-80=168

and from equation (iii)

x=2x124-93=155.

Hence, the number of free​ throws, two-point field​ goals, and​ three-point field goals Rebecca Smith made during the 2006 regular season are 155, 168, and 124 respectively.

Answer: 192 IS IRRATIONAL. I HOPE THIS ANSWER HELPS.

Step-by-step explanation:

It is an irrational number if it is not a perfect square. Since 192 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 192?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

Answer:

im not the best in math but I think its 95 since a line segment is 180 degrees and you add tge two number and subtract what you have

hope this hells

Answer:

= 10x + 20

Step-by-step explanation:

If I helped may I get brainliest?

Answer:

x=6.5

Step-by-step explanation:

1. simplify the equation to 10x + 20 +85

2. minus 20 from both sides to get 10x =65

3. divide 10 from both sides

4. x= 6.5

Answer: 46.7

Step-by-step explanation:

Answer:

1/28

Step-by-step explanation:

[tex]\frac{x}{1}= \frac{1}{28}[/tex]

cross multiply and you get 1/28

So,

Ignore the negatives and just make them positives.

For now.

Then, you look at 3/5 and say... it's 3 ticks towards the number five,

meaning it's between 4 and 5. After you do that whats happens is you place back the negatives and you have -3/5 and -2.

-2 < 5 and -2 < 4

Meaning it goes more to the left.

I could be wrong but If I'm right please mark brainliest

Answer:

(4,5)

Step-by-step explanation:

Rotating a point by 90 degrees counterclockwise would make the y become x and switch it's negative/positive value, and make x the y.

Ex: (x,y) would become (-y,x)

7/10 = 0.7

198/100 = 1.98

85/100 = 0.85

45/100 = 0.45

1/4 = 0.25

3/2 = 1.5

3/8 = 0.375

1/9 = 0.11111111    ( goes on forever)        ( sigue para siempre )
