​ y=3x+3 y=−2x+3 ​ how many solutions does the system have

Answer:

x = 30

Step-by-step explanation:

We start off with 90 degrees

2x + x = 90

Add all like terms

3x = 90

Divide 3 on both sides

[tex]\frac{3x} {3} = \frac{90} {3}[/tex]

x = 30

To check your answer:

Let x be 30

2x + x = 90

2 (x 30) + 30 = 90

60 + 30 = 90

90 = 90

Answer:

i don’t know

Step-by-step explanation:

Answer:

n = -20

Step-by-step explanation:

-7 + [tex]\frac{n}{5}[/tex] = -11

*multiply both sides by 5*

-35 + n = -55

*add 35 to each side*

n = -55 + 35

*calculate the sum*

n = -20

Answer:

x = 3

Step-by-step explanation:

arc KP = 50 degrees

arc KRQ = 2(110) = 220 degrees

arc 30x = 360 - 220 - 50 = 90 degrees

30x = 90

x = 3

Answer:

Jerome got 5 quarters, 1 dime and, and 3 nickels.

Step-by-step explanation:

Let's define the variables:

N = number of nickels he got

D = number of dimes he got

Q = number of quarters he got

We know that the nickels were worth $0.15

And each nickel is whort $0.05

Then:

N*$0.05 = $0.15

N = $0.15/$0.05 = 3

N = 3

Now we also know that there is a total of 9 coins, then:

N + D + Q = 9

3 + D + Q = 9

D + Q = 9 - 3 = 6

D + Q = 6

And we also know that the total change received is $1.50, then:

D*$0.10 + Q*$0.25 + N*$0.05 = $1.50

We know that N = 3, then we can replace that and get:

D*$0.10 + Q*$0.25 + 3*$0.05 = $1.50

D*$0.10 + Q*$0.25 = $1.50 - $0.15 = $1.35

D*$0.10 + Q*$0.25 = $1.35

Then we have two equations:

D + Q = 6

D*$0.10 + Q*$0.25 = $1.35

To solve this, we can isolate one of the variables in one of the equations, i will isolate D in the first one:

D = 6 - Q

Now we can replace this in the other equation:

(6 - Q)*$0.10 + Q*$0.25 = $1.35

Now we need to solve this for Q.

$0.60 - Q*$0.10 + Q*$0.25 = $1.35

Q*$0.15 = $1.35 - $0.60 = $0.75

Q = ($0.75)/($0.15) = 5

Q = 5

Then Jerome has 5 quarters.

Now we can return to the equation:

N + Q + D = 9

We already know that:

N = 3

Q = 5

Then if we replace those in the equation, we get:

3 + 5 + D = 9

8 + D = 9

D = 9 - 8 = 1

D = 1

Answer:

the answer is D (4,-8)

Step-by-step explanation:

Its 4,-8

Step-by-step explanation:

12=3x-2y

2y+12=3x

2y=3x-12

y=(3x-12)/2

y=mx+b

To be parallel to the line above our line must have the same slope or m. The above line has a slope of 3/2 or 1.5 so the parallel line will be

y=1.5x+b, using point (7,10) we can solve for the y intercept or b

10=1.5(7)+b

10=10.5+b

b=-0.5 so our line is

y=1.5x-0.5

Given that, the diameter of the circle 15 m. The circumference of a circle is 2πr. Then the circumference of the circle with the given diameter is 47.1  m.

Circumference of a circle is also called its perimeter and it describes the overall area of the surrounding circular path. The distance round a circle is its circumference, but this cannot be used as a definition if, as in many elementary treatments, distance is defined in terms of straight lines.

In these conditions, the limit of the perimeters of inscribed regular polygons may be described as the circumference of a circle as the number of sides increases without constraint.  When describing abstract geometric forms as well as measuring real-world things, the term circumference is frequently used.

It is given that, the diameter of the circle = 15 m

radius r  = diameter/ 2 = 15 m/ 2 = 7.5 m

circumference of circle = 2 π r

                                       = 2 × 3.14 × 7.5 m

                                       = 47.1 m

Answer:

l = 4w + 3

Step-by-step explanation:

Answer:

a. 45 + 20x

   30 + 26x

b. 2.5 hours

c. 95

Step-by-step explanation:

45 + 20x = 30 + 26x

subtract 30 from both sides of the equation

15 + 20x = 26x

subtract 20x from both sides of the equation

15 = 6x

divide 6x on both sides of the equation

2.5 = x

Answer:

The ordered pair works for the first equation on the top, but not the second equation on the bottom.

Step-by-step explanation:

You have to plug in the x and y values into the equations:

x - 2y = -6

2 - 2(4) = -6  

That equation works.

...now for the next one...

3x + 2y = 12

3(2) + 2(4) = 12

That equation doesn't work.

Answer:

£5

Step-by-step explanation:

5 boxes will cose 5 x 15.40 = 77 normally.

according to the table, he will get 6.5% discount.

6.5 percent of 77 is 77x0.065 = 5.005 ≈ 5

Answer:

he orders 5 boxes of paperclips, that comes around to 77 dollars. That means he will get a 6.5 percent discount. So you would multiply 77 by .065 and you would get 5.005. You would take that number and subtract it by 77 and would get 71.995 and you can round that up to 72 dollars. My guess is that either 72 or 5.005 is the answer as 72 dollars is the price after the discount and 5.005 is how much he is saving

Answer:

25 years

Step-by-step explanation:

Given data

Principal P=  $2000

Interest rate r=  6%

FInal amount A=$5,000

The simple interest formula is given as

A=P(1+rt)

substitute and solve for t

5000=2000(1+0.06*t)

5000=2000+120t

5000-2000=120t

3000=120t

t= 3000/120

t= 25 years

Hence, for a simple interest investment, she will be 25 years
