You deposit $5000 into a bank account paying 6.3% simple interest per year. You left the money in for 3 years. How much interest do you get at the end of those 3 years?

Result

The interest is $945.

Then you add 5000 to your interest rate of 945 so your answer would be 5945 . I think I'm not that great with math but I really hope I helped .

Step 1. Simplify 7/9(6x - 36) to 7(6x - 36)/9

23 = 7(6x - 36)/9 + 9

Step 2. Factor out the common term

23 = 7 * 6(x - 6)/9 + 9

Step 3. Simplify 7 * 6(x - 6) to 42(x - 6)

23 = 42(x - 6)/9 + 9

Step 4. Simplify 42(x - 6)/9 to 14(x - 6)/3

23 = 14(x - 6)/3 + 9

Step 5. Subtract 9 from both sides

23 - 9 = 14(x - 6)/3

Step 6. Simplify 23 - 9 to 14

14 = 14(x - 6)/3

Step 7. Multiply both sides by 3

14 * 3 = 14(x - 60

Step 8. Simplify 14 * 3 to 42

42 = 14(x - 6)

Step 9. Divide both sides by 14

42/14 to x - 6

Step 10. Simplify 42/14 to 3

3 = x - 6

Step 11. Add 6 to both sides

3 + 6 = x

Step 12. Simplify 3 + 6 to 9

9 = x

Step 13. Switch sides

x = 9

Final answer:

The solution to the equation is x = 9.

Explanation:

To solve for x, we need to isolate it on one side of the equation.

Let's start by distributing 7/9 to the terms inside the parentheses:

23 = (7/9)(6x - 36) + 9

Next, simplify the expression inside the parentheses:

23 = (7/9)(6x) - (7/9)(36) + 9

Now, multiply 7/9 with 6x and 36:

23 = (42/9)x - (252/9) + 9

Simplify the fractions:

23 = (14/3)x - (28/1) + 9

Combining the constants:

23 = (14/3)x - 19

Add 19 to both sides:

23 + 19 = (14/3)x

Now we have:

42 = (14/3)x

To isolate x, divide both sides by 14/3:

42 / (14/3) = x

Simplify the expression:

42 * (3/14) = x

Now, calculate:

x = 9

Let the number of students in the class be x

Let the number of pieces of gum she gave out be 3x

Equation

3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.

3(x - 1) + 8 = 168      This doesn't work either.

Well we have to choose. It's a rounding problem.

3x + 8 = 168     Subtract 8 from both sides.

3x = 168 - 8      Combine

3x = 160           Divide by 3 on both sides.

x = 160 / 3

x = 53.333333333

Since that can't be, we could say there were 53 students.

Could you include the entire picture in your question please? It would help me to answer your question.

Step-by-step explanation:

b1 = 2A/h - b2 would be your answer from what I can see in the picture.

∠n and ∠p are supllementary angles, therefore m∠n + m∠p = 180°.

[tex]m\angle p=21x+25\\\\m\angle n=\dfrac{675x-27}{3}=\dfrac{675x}{3}-\dfrac{27}{3}=225x-9[/tex]

therefore

[tex](21x+25)+(225x-9)=180\\\\(21x+225x)+(25-9)=180\\\\246x+16=180\qquad|-16\\\\246x=164\qquad|:246\\\\x=\dfrac{164}{246}\\\\x=\dfrac{2}{3}[/tex]

[tex]m\angle p=21x+25[/tex]

substitute

[tex]m\angle p=21\cdot\dfrac{2}{3}+25=7\cdot2+25=14+25=39^o[/tex]

[tex]m\angle n=225x-9[/tex]

substitute

[tex]m\angle n=225\cdot\dfrac{2}{3}-9=75\cdot2-9=150-9=141^o[/tex]

Angles on a straight line add up to [tex]180^o[/tex].

Given that:

[tex]\angle p = 21x + 25[/tex]

[tex]\angle n = \frac{675x - 27}3[/tex]

To calculate the value of x, we use:

[tex]\angle p + \angle n = 180^o[/tex] --- angle on a straight line.

So, we have:

[tex]21x + 25 + \frac{675x - 27}{3} = 180[/tex]

[tex]21x + 25 + 225x - 9 = 180[/tex]

Collect like terms

[tex]21x + 225x = 180 + 9 - 25[/tex]

[tex]246x = 164[/tex]

Divide both sides by 246

[tex]x = \frac 23[/tex]

To calculate the measures of p and n, we substitute [tex]x = \frac 23[/tex] in

[tex]\angle p = 21x + 25[/tex]

[tex]\angle n = \frac{675x - 27}3[/tex]

So, we have:

[tex]\angle p = 21x + 25[/tex]

[tex]\angle p = 21 \times \frac 23 + 25[/tex]

[tex]\angle p = 39[/tex]

[tex]\angle n = \frac{675x - 27}3[/tex]

[tex]\angle n = \frac{675 \times 2/3 - 27}{3}[/tex]

[tex]\angle n = 141[/tex]

Hence, the value of x is 2/3.

We know, 3 feet = 1 yard.

We have to convert feet to yards to calculate the ratio so that the final answer doesn't have any unit.

Therefore, 21 feet = [tex]\frac{21 feet}{3 feet}yards[/tex] = 7 yards

Thus, the ratio

[tex]\frac{21feet}{8yards} =\frac{7yards}{8yards} =\frac{7}{8}[/tex]

The fraction [tex]\frac{7}{8}[/tex] is already in its simplest form.

Therefore, the given ratio as a fraction in the simplest form without any units is [tex]\frac{7}{8}[/tex]

Final answer:

The ratio of 21 feet to 8 yards simplifies to 7/8 when both measurements are converted to the same units (feet) and the ratio is reduced to simplest form.

Explanation:

To write the ratio of 21 feet to 8 yards as a fraction in simplest form without any units, first, we need to ensure both measurements are in the same unit.

We know that 1 yard equals 3 feet, so 8 yards equal 24 feet. Therefore, the ratio of 21 feet to 8 yards (24 feet) can be written as 21 to 24, which simplifies to 7/8 when dividing both numbers by their greatest common divisor, which is 3.

Step-by-step explanation:

The fractions in this equation are 3/4 and 5/6. The denominators of those fractions are 4 and 6. The lowest common multiple (LCM) of the numbers 4 and 6 is 12. The LCM is 12 because this is the smallest multiple 4 and 6 have in common

Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, ....

Multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, ....

The LCM has been highlighted in bold to make it easier to spot

Therefore, the LCD (lowest common denominator) of the fractions is 12. If we were to multiply both sides of this equation by the LCD, then we will clear out the fractions entirely to have whole numbers only left over.

Final Answer: 9x + 36 = 10

the answer to the first one is b,c

The algebraic expression '5c + 12d - 6' cannot be simplified without knowing the values of the variables 'c' and 'd'. With specific values, you will be able to simplify the expression. For example, if c is 2 and d is 3, the expression simplifies to 40.

The expression given, 5c + 12d - 6, is an algebraic expression which consists of variables, constants, and operations. Here, the variables are 'c' and 'd', the constants are 5, 12 and -6, and the operations are addition and subtraction.

In order to simplify this expression, we should know the values of the variables. Without knowing the specific values of 'c' and 'd', the expression 5c + 12d - 6 cannot be simplified any further.

Let me explain with an example. If 'c' is 2 and 'd' is 3, you would replace the variables 'c' and 'd' in the expression with their given values. This would give: 5(2) + 12(3) - 6 = 10 + 36 - 6 = 40. But without specific values for 'c' and 'd', the expression remains as 5c + 12d - 6.

Most expensive thing she can afford after 7 years is of worth 2560$

Explanation:

We need to calculate the interest on $2000 at 4% interest per year after 7 year(s).

The formula we'll use for this is the simple interest formula, I = P*r*t, I is the interest after t years, r is interest rate and P is the invest amount.

P = 2000$, r = 4/100 = 0.04, t = 7 years

So , I = 2000* 0.04 * 7 = 560$

Total amount she can retrieve from bank = P+I = 2000 + 560 = 2560$

Most expensive thing she can afford after 7 years is of worth 2560$

5(2x +8) = -8x + 4

Use distributive property:

10x +40 = -8x + 4

Subtract 40 from each side:

10x = -8x -36

Add 8x to each side:

18x = -36

Divide both sides by 18:

x = -36 / 18

x = -2

The number is -2

Remark

The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?

Solution

36 * (x/100) = 29.52   Multiply both sides by 100

36 * x = 29.52 * 100  The 100 on the left disappears.

36 * x = 2952              The decimal disappears. Divide by 36

x = 2952/36

x = 82%

That is not your answer. That just tells you what % of 36 is that would give 29.52

Answer

The % discount is 100 - 82 = 18%. That is the % discount.

Final answer:

The percentage discount on the boots is calculated by first finding the discount amount ($6.48) and then dividing it by the original price ($36.00), which gives us an 18% discount.

Explanation:

To calculate the percentage discount on the boots, we must first determine the amount of the discount. The discount is the difference between the original price and the sale price, which is $36.00 - $29.52 = $6.48.

Next, we calculate the percentage discount using the formula:

Percentage Discount = (Discount ÷ Original Price) × 100%

Substituting in our numbers:

Percentage Discount = ($6.48 ÷ $36.00) × 100%

Percentage Discount = 0.18 × 100%

Percentage Discount = 18%

So, Jeremiah received an 18% discount on the boots.
