6x+18
So that is the answer because you multiply 6 by x and 6 by 3.

Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

I=Prt

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

I=Pr(3)\\

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

I=\frac{Pr(4)}{12}

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

I=\frac{Pr(45)}{365}

4x + x - 3-9 + 4x = 6 ??​
Nookie1986 [14]

Answer:

x=2

Step-by-step explanation:

-------------------------

Given:

4x+x-3-9+4x=6

---------->>>>

Combine like terms.

9x-12=6

---------->>>>

Add 12 to both sides.

9x=18

---------->>>>

Divide both sides by 9.

x=2

-------------------------

Hope this is helpful.

Answer the equation
ivanzaharov [21]

Answer:

x = -2, y = -4

coordinate: (-2, -4)

Step-by-step explanation:

Given system of equations:

a) 4x - 7y = 20

b) x - 3y = 10

1. Make x the subject in the <em>second</em> equation:

⇒ x - 3y = 10 [add 3y to both sides]

⇒ x - 3y + 3y = 10 + 3y

⇒ x = 3y + 10

2. Substitute the given value of x into <em>first</em> equation:

⇒ 4x - 7y = 20

⇒ 4(3y + 10) - 7y = 20 [distribute 4 through the parentheses]

⇒12y + 40 - 7y = 20 [combine like terms]

⇒ 5y + 40 = 20 [subtract 40 from both sides]

⇒ 5y - 40 - 40 = 20 - 40

⇒ 5y = -20 [divide both sides by 5]

⇒ 5y ÷ 5 = -20 ÷ 5

⇒ y = -4

3. Find the value of x by substituting the given value of y into x = 3y + 10:

⇒ x = 3y + 10

⇒ x = 3(-4) + 10 [multiply]

⇒ x = -12 + 10 [add]

⇒ x = -2

4. Check your work:

<em>a) 4x - 7y = 20</em>

⇒ 4(-2) - 7(-4) = 20

⇒ -8 + 28 = 20

⇒ 20 = 20 ✔

<em>b) x - 3y = 10</em>

⇒ -2 - 3(-4) = 10

⇒ -2 + 12 = 10

⇒ 10 = 10 ✔

This system of equations has a solution at (-2, -4).
