Answer:

G 15.99h > 188.55 + 9.75h

Step-by-step explanation:

Using the distributive property, distributing -1 ; multiplies each term in the parenthesis by a negative sign. Hence, it is similar to subtraction because You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.

The additive inverse of a value is the value which ensures that the addition of two values gives 0.

Using the relation :

(w + x) - (y + z)

The negative sign implies distributing -1 to all values in the parenthesis ;

w + x - y - z

Hence, it is similar to using the subtraction operation directly :

(w + x) - y - z

Therefore, subtraction ls similar to distributing - 1

Step-by-step explanation:

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?

This is a simple interest question

The formula to find the rate is given as:

Equation:

r = (1/t)(A/P - 1)

t = time = 4 years

P = Principal = $12500

I = Simple Interest = $1500

A = Total Amount = Principal + Simple Interest = $12500 + $1500

= $14000

Calculation:

Solving our equation:

r = (1/4)((14000/12500) - 1) = 0.03

r = 0.03

Converting r decimal to R a percentage

R = 0.03 * 100 = 3%/year

Answer:

v=−27

Step-by-step explanation:

Since v is on the right side of the equation, switch the sides so it is on the left side of the equation.

−6(3v−4)+8v=4(v+7)

Simplify −6(3v−4)+8v

−10v+24=4(v+7)

Simplify 4(v+7).

−10v+24=4v+28

Move all terms containing v to the left side of the equation.

−14v+24=28

Move all terms not containing v to the right side of the equation.

−14v=4

Divide each term by −14 and simplify.

v=−27

The result can be shown in multiple forms.

Exact Form:

v=−27

Answer:

60 Yards.

Step-by-step explanation:

Ooooooooo Proportion question!

We can write an equivalent fraction here:

[tex]\frac{1}{5} =\frac{12}{x}[/tex]

Because 12 wold be equivalent to the 1 inches.

We can multiply by 12 because 1*12 would be 12.

5*12=60.

x=60, which is the answer.

Answer:

1200 ounces

Step-by-step explanation:

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?

Let us represent

Number of ounce of 10% copper = x

Hence, our Equation =

x × 10% + 600 × 70% = (x + 600) × 30%

0.1x + 420 = (x + 600)0.3

0.1x + 420 = 0.3x + 180

Collect like terms

0.3x - 0.1x = 420 - 180

0.2x = 240

x = 240/0.2

x = 1200 ounces

Answer:

According to logarithmic properties.... The right hand side can be written as

log base 7 (180/3).....which is log base 7 60

So according to the question cancel out the log base 7 from both sides....

Then we get 8r + 20 = 60

That is 8r = 40..

That is r = 5......

Therefore the value of r is 5

Answer:

width = 40 cm

Step-by-step explanation:

Since the pentagons are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{4x}{x}[/tex] = [tex]\frac{48}{x+2}[/tex] ( cross- multiply )

4x(x + 2) = 48x ← distribute left side

4x² + 8x = 48x ( subtract 48x from both sides )

4x² - 40x = 0 ← factor out 4x from each term on left side

4x(x - 10) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

x - 10 = 0 ⇒ x = 10

However, x > 0 then x = 10

Thus width = 4x = 4 × 10 = 40 cm
