-2(x - 3) = -3x + 8

Answer:

x=-2

Step-by-step explanation:

First step, add 4 to both sides because +4 cancels out -4

x-(-4)=-6

   +4   +4      Well I guess the first step was also the last step.. XD

x=-2

Answer:

c = 32

Step-by-step explanation:

90 + 58 + c = 180

90 + 58 = 148

180 - 148 = 32

c = 32

Answer:

32

Step-by-step explanation:

As we know the total degree of a triangle is 180 degrees.

In this triangle so far we have a 58 degree and 90 degree box since its a right triangle so we have to take:

58 + 90 = 148

After taking 148 we have to subtract the 180 to find the missing number that will help us complete everything:

180 - 148 = 32

Step-by-step explanation:

1.Solve for x. 2x+5=17 (x=6)

2.Solve for x. 2(x+9)=24 (x=3)

3.Solve for x. 25=4+7x (x=3)

4.Solve for x. x/3-6=4  (x=30)

5.Solve for x 4x+8=20 (x=3)

hope this helps

Answer:

1. 2x + 5 = 17

Subtract both sides of the equation by 5 to get 2x = 12

Divide both sides by 2 to get x=6

2. 2 (x+9)= 24

Distribute 2 to x and 9 by multiplying to get

2x + 18 = 24

Subtract 18 from both sides to get 2x = 6

Divide both sides by 2

x=3

3. 25= 4 + 7x

Rearrange the equation to get 7x+4=25

Subtract 4 from both sides 7x=21

Divide both sides by 7 to get

x=3

4. x/3 - 6=4

Add 6 to both sides of the equation to get x/3=10

Multiply both sides by 3 to get

x= 30

5. 4x+8=20

Subtract 8 from both sides of the equation to get 4x=12

Divide both sides of the equation by 4

x=3

Answer:

27 years old

Step-by-step explanation:

What I know

Let D = Dave, S = Sabrina, etc. Then:

(1) [tex]D=0.15S[/tex]

(2) [tex]L=0.75S[/tex]

(3) [tex]R=3.00D[/tex]

(4) [tex]D+S+L+R=141[/tex]

Want to find R. Taking equation 3 and rewriting equation 4, we get

[tex]R=3.00D[/tex]

[tex]R=141-D-S-L[/tex]

So if [tex]R=R[/tex], then

[tex]3D=141-D-S-L-R[/tex]

[tex]4D=141-S-L[/tex] by adding [tex]D[/tex] to both sides.

Using equation 1 and equation 2, I can rewrite everything in terms of [tex]S[/tex] and get:

[tex]4(0.15S)=141-S-0.75S[/tex]

[tex]0.6S=141-1.75S[/tex]

[tex]2.35S=141[/tex] by adding [tex]1.75S[/tex] to both sides.

[tex]S=60[/tex] by dividing 2.35 both sides.

Now that I know Sabrina's age, I'll work towards getting Rhianna's using equation 1 and equation 3:

[tex]D=0.15(60)=9[/tex]

[tex]R=3.00(9)=27[/tex]

Checking my work:

Dave: 9

Sabrina: 60

Luca: 45 (since 9+60+45+27=141)

Rhianna: 27

9 is 15% of 60

45 is 75% of 60

27 is 300% of 9

The Fundamental Counting Theorem states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the total number of outcomes is calculated by the multiplication of the number of outcomes for each trial as presented as follows:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

For this problem, we have that the parameters are given as follows:

Hence the total number of combinations is given as follows:

Answer:

$167.50

$1507.50

$134

Step-by-step explanation:

Given that:

Cost of sound system = 1675

APR, = 12%

Down payment = 10%

Number of monthly payments = 12

r = 0.12 / 12 = 0.01

Amount of down-payment :

10% * cost of sound system

0.1 * 1675 = $167.50

Amount to be financed :

$1675 - $167.50

= $1507.50

Monthly repayment :

Using the relation :

A / {[(1+r)^n]-1}/[r(1+r)^n]

1507.5 / (1+0.01)^12-1)/(0.01(1+0.01)^12)

1507.50 / 0.1268/(0.01 * 1.1268)

1507.50 ÷ (0.1268/0.01126)

1507.50 ÷ 11.25

= $134

Answer:

y=3x+2

Step-by-step explanation:

slope= rise/run

rise=3  run=1 slope=3

y intercept is 2

y=3x+2

Answer:

y = 3x + 2

Step-by-step explanation:

(1, 5) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-5)/(2-1)

m=3/1

m=3

y - y1 = m(x - x1)

y - 5 = 3(x - 1)

y - 5 = 3x - 3

y = 3x + 2

Step-by-step explanation:

(a) we are trying to find "?" for this explanation. I came up with the equation 60=6 x ?. The 60 shows us the total amount of dollars that the 6 shares went down. We need to find the amount. of dollars that went down for 1 stock. So we divide 60 by 6. and get 10.

(b) we are trying to find "?" for this explanation. I came up with the equation

?=7 x 14. All you have to so is multiply 7 by 14 and you get 98.
