Answer:

Step-by-step explanation: . Paid to the painter for 12 hrs=Rs.360........therefore,......amt paid for 1 hr=360/12=30......... Therefore,.....amt paid for 9 hrs=9*30=Rs.270........hope i helped u:)

The amount paid for 9 hours is R270

The expression can be represented by using the following ratio

Ratio = Amount : Time

So, we have:

R360 : 12 = Amount : 9

Express as fraction

R360 / 12 = Amount / 9

Multiply both sides by 9

Amount = R360 / 12 * 9

Evaluate the product

Amount = R270

Hence, the amount paid for 9 hours is R270

Answer: -19+5x

Step-by-step explanation: Another expression for the term.

The required sum is 2 + (−4) + (−10) + (−16) + (−22)

From the given sum of a sequence, we are to find the sum of the given sequence from n = 0 to n = 4

When n = 0

a(0) = 2 - 6(0)

a(0) = 2 - 0
a(0) = 2

When n = 1

a(1) = 2 - 6(1)

a(1) = 2 -6
a(1) = -4

When n = 2

a(2) = 2 - 6(2)

a(2) = 2 - 12
a(2) = -10

When n = 3

a(3) = 2 - 6(3)

a(3) = 2 - 18
a(3) = -16

When n = 4

a(4) = 2 - 6(4)

a(4) = 2 - 24
a(4) = -22
Hence the required sum is 2 + (−4) + (−10) + (−16) + (−22)

Answer:

x=7

y=-17

Step-by-step explanation:

Lets do 10x-7. Basically it will be equal to 63, so the equation will be 10x-7=63

to find x we need to add 63+7=70 and put 10x with an equal sign which is 70=10x

7=x because 70/10=7.

in a simple way it is

10x-7=63

10x=7+63=70

10x=70

x=7

Lets do -5y+3. It is equal to 88.

so it will be

-5y+3=88

-5y=88-3=85

-5y=85

y=-17

Answer:

[tex]\Longrightarrow: \boxed{\sf{x=7, \ y=-17}}[/tex]

Step-by-step explanation:

To find the value of x and y in the parallelogram, you have to isolate it on one side of the equation.

First, add by 7 from both sides.

10x-7+7=63+7

Solve.

Add the numbers from left to right.

63+7=70

10x=70

Then, you divide by 10 from both sides.

10x/10=70/10

Solve.

Divide these numbers goes from left to right.

70/10=7

[tex]\Longrightarrow: \boxed{\sf{x=7}}[/tex]

Subtract by 3 from both sides.

-5y+3-3=88-3

Solve.

Subtract the numbers from left to right.

88-3=85

-5y=85

Divide by -5 from both sides.

-5y/-5=85/-5

Solve.

Divide the numbers from left to right.

85/-5=-17

[tex]\Longrightarrow: \boxed{\sf{y=-17}}[/tex]

The monthly loan payment should be $168.75.

Since Ally is buying a speed boat for $10,000 with a down payment of $2,500. The bank approved a simple interest flat rate loan for 5 years at 7% APR.

The net principal should be

= $10,000 - $2,500

= $7,500

Now simple interest should be

= $7,500(5)(7%)

= $2,625

Now the total amount should be

= $7,500 + $2,625

= $10,125

Now the monthly payment is

[tex]= 10125\div (12\times 5)\\\\= 10125 \div 60[/tex]

= $168.75

Therefore, The monthly loan payment should be $168.75.

Y=-1x+5

Slope intercept form is y=mx+b

m = slope

b = y intercept

As you can see from the line, the y-intercept if 5, so b is 5. To find the slope, we take two points, I'm using (0,5) and (2,3), and then divide change y by change in x or y2-y1 / x2-x1  

3-5   /  2-0

= -2/2= -1
