Answer 1

Answer:

(- 1, 4 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 13 → (1)

2x - 2y = - 10 → (2)

Multiplying (2) by 2 and adding to (1) eliminates the term in y

4x - 4y = - 20 → (3)

Add (1) and (3) term by term to eliminate y, that is

7x + 0 = - 7

7x = - 7 ( divide both sides by 7 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (1)

3(- 1) + 4y = 13

- 3 + 4y = 13 ( add 3 to both sides )

4y = 16 ( divide both sides by 4 )

y = 4

solution is (- 1, 4 )

Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. For how many years did he save this money?

Answers

Answer:

7 years.

Step-by-step explanation:

To find this, we need to find 2% of 2,000. To do this, we mulitply 2,000 by .02. This gets us 40. Now, we need to divide 280 by 40 to find the amount of years it took for Mike to get this money. When we do that, it gets us 7. That means Mike saved that money for 7 years.

The number of years that he saves this money will be 7 years.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Mike saves $2,000 at a yearly simple interest rate of 2%. He earns $280 in interest. Then the number of years is calculated as,

$280 = ($2,000 x 2 x T) / 100

$28,000 = $4,000 x T

T = $28,000 / $4,000

T = 7 years

The number of years that he saves this money will be 7 years.

The length of a rectangle is 5 less than 3 times the width. What is the length?

Perimeter = 46 inches
Write an inequality or equation, then solve.

Answers

Answer:

Let the width of the Rectangle be x inches

Then, length is (3x-5) inches

Perimeter of the Rectangle= 46 inches (given)

According to the above problem,

Equation :---- Perimeter=2(length+breadth)

2{(3x-5)+x}=46

2(4x-5)=46

(4x-5)=46/2=23

4x=(23+5)=28

x=28/4

x=7

So, length of the Rectangle is {(3×7)-5}=16 inches

and width is= 7 inches

Judy makes 2/5 of a beaded necklace on Monday she makes 3/10 of the necklace on Tuesday she makes 1/5 of the necklace on Wednesday what fraction of the necklace has Judy made so far

Answers

Answer: 9/10

Step-by-step explanation:

Fraction of beaded necklace made on Monday = 2/5

Fraction of beaded necklace made on Tuesday = 3/10

Fraction of beaded necklace made on Wednesday = 1/5

Total fraction made would be the addition of the Fractions made from Monday to Wednesday. This would be:

= 2/5 + 3/10 + 1/5

The lowest common multiple of the denominator is 10. Therefore we'll make them have a common denominator.

= 2/5 + 3/10 + 1/5

= 4/10 + 3/10 + 2/10

= 9/10
