Walter invested some money at 5% simple interest for 3 years and earned $300. What was the amount he invested?

Answer:

H= -18

Step-by-step explanation:

A negative × a positive = a negative

take the original product and add a "-"

Answer: Multiply each equation by the value that makes the coefficients of opposite.

(−2) ⋅ (3x−15y) = (−2) (9) (-2) ⋅ (3x-15y) = (-2) (9) (3) ⋅ (2x−10y) = (3) (6)

Simplify.

–6x+30y= − 18

6x − 30y = 18

i hope this answers it

Answer: The first one

Step-by-step explanation: first you have to subtract 5 from both sides and then you have -6n < 6 . Then you have to divide both sides by -6 then you get n < -1.

Answer and Step-by-step explanation:

Hello!

You are told to round the number to the nearest whole number.

That means if the decimal is lower than 5 in the tenths place, the number would round down, and if the decimal is equal to or higher than 5 in the tenths place, the number would round up.

[tex]5\frac{5}{6}[/tex] is equal to 5.833. The number 8 is greater than 5, so the number rounds up to 6.

[tex]6\frac{1}{9}[/tex] is equal to 6.111. The number 1 is less than 5, so the number rounds down to 6.

Now we have the equation n - 6 = 6.

We solve for n.

Add 6 to both sides.

n  =  12

n is equal to 12.

Answer: 6.5

Step-by-step explanation: just trust me

The length of side k is approximately 6.56 inches.

A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle between them, divided by two.

We can use the Law of Cosines to find the length of side k:

k² = l² + m² - 2lm cos(K)

where K is the angle opposite side k.

In this case, we have l = 2.4 inches, m = 4.2 inches, and K = 159°. Substituting these values into the formula, we get:

k² = (2.4)² + (4.2)² - 2(2.4)(4.2)cos(159°)

Using a calculator to evaluate the cosine, we get:

k² = 5.76 + 17.64 - 19.96(-0.987688)

k² ≈ 43.11

Taking the square root of both sides (and rounding to the nearest tenth), we get:

k ≈ 6.56 inches

Therefore, the length of side k is approximately 6.56 inches.

Answer: See explanation

Step-by-step explanation:

The information given in the question can be turned into an equation as:

2u + y = 30 ........ i

5u + y = 42 ........ ii

Subtract i from ii

3u = 12

u = 12/3 = 4

A pair of socks cost $4

Since 2u + y = 30

2(4) + y = 30

8 + y = 30

y = 30 - 8 = 22

A pair of slippers cost $22

Answer:

  A = 250

  B = 75

  C = 40

Step-by-step explanation:

Apparently, we're supposed to assume that the "health gained" is proportional to the "time in circle." The constant of proportionality is 100/4 = 25. This means all the numbers in the right column are 25 times those in the left column:

  A = 25·10 = 250

  B = 25·3 = 75

  C·25 = 1000   ⇒   C = 40 . . . . . note these numbers are 10 times those in the first row

Answer:

6z-7>8z+2? =  z < -9/2

Step-by-step explanation:

6*z-7-(8*z+2)>0

  -2z - 9  =   -1 • (2z + 9

Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     2z+9  < 0

Divide both sides by  2  

     z+(9/2)  < 0

Subtract  9/2  from both sides

           z < -9/2

Answer: z < -9/2

Answer:

z is (less than) -9/2 is the correct answer use the symbol for less than.

Answer:

2^4

Step-by-step explanation:

2^2 = 2 * 2 = 4

4^4 = 4*4*4*4 = 256

2^4 = 4*4 = 16

8^2 = 8*8 = 64

2^8 = 2*2*2*2*2*2*2*2 = 256

Hence, 16 can be written as 2^4

Thus, Answer is [C] 2^4

Step-by-step explanation:

slope of required line=5

point is (-1,0)

reqd. eq. of line is

y-0=5(x-(-1))

y=5(x+1)

y=5x+5

If two sides and a angle are given, then this can be used to find a second angle. With being given the measurements of two sides and an angle, this could result in one or two triangles. Johannes von Muller was the one who was discovered the Law of Sines

Answer:

The slope=1/4

Step-by-step explanation:

(16, 0) = (x,y) and (4, -3) = (`x, `y)

formula for finding slope is `y - y/ `x - x

-3 - 0/ 4 - 16

-3 / -12 = 3/12 = 1/4

Therefore, the slope = 1/4
