0.25(x +4) -3 = 28
What is the value of x?

Answers

Answer 1

Answer:

120

Step-by-step explanation:

0.25=1/4

1/4(x+4)-3=28 /times 4

1(x+4)-12=112

x+4-12=112

x-8=112

x=120

Answer 2

The value of x for the given expression will be equal to 120.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is 0.25(x +4) -3 = 28.

Conver the value 0.25 into fractions,

0.25=1/4

Apply the mathematical operations to get the value of x below,

1(x+4)-12=112

x+4-12=112

x-8=112

x=120

Therefore, the value of x for the given expression will be equal to 120.

Angle between the pair of straight lines is zero therefore the lines are parallel.

Hence proved

Angle between the pair of straight lines is zero therefore the lines are parallel.

What is parallel lines?

Parallel lines can be defined as two lines in the same plane that their angle of inclidation is equal and never meet.

Given,

x²+6xy+9y²-4x+12y-5=0

Comparing the equation with the general equation of 2nd degree

ax² + ay² + 2gx + 2fy + c = 0

so a=1, b=9, h= 3, g=-2, f=6, c=5

Angle between a pair of straight lines that is

tan∅=[tex]\frac{2\sqrt{h^{2} -ab} }{a+b}[/tex]

tan∅=[tex]\frac{2\sqrt{3^{2} -(1)(9)} }{1+9}[/tex]

tan∅=0°

∅=0°

Hence Angle between the pair of straight lines is zero therefore the lines are parallel.

David borrows $15,000 for a new car. He is charged 6% simple interest per year. If he paid $4500 in interest, how many years did it take him to repay the loan?

Answers

Answer:

5 years

Step-by-step explanation:

Given that:

Amount borrowed = principal = p = $15000

Interest % per year = r = 6% = 0?06

Total Interest paid = $4500

Number of years it took to repay the loan (t) =?

Simple interest = (p * r * t)

4500 = (15000 * 0.06 * t)

4500 = 900t

4500 / 900 = t

5 = t

It tool 5 years to repay the loan

The reason why I chose ball 4 was because ball 4 has less mass and the mass for ball 4 is only 300 and I'm pretty sure if you rolled ball 4 it would've went the farthest because it's mass is lesser than the others.

i’d say 4

Answers

Answer:

400$

Step-by-step explanation:

since he receives 20 percent of the sales and he receives 80 dollars. Then 80 dollars is 20 percent of the sales. Now, we can change 20 percent into a fraction, 20 percent is 20/100 or 2/10, now there are 5 twos in a ten so we multiply 2/10 by 5, since 2/10 right now is 80 dollars you multiply 80 by 5

80*5=400, so the sales of the week was 400 dollars

Hope this helps :)

Answer:

Thus, the sales of the week were $400

Step-by-step explanation:

Percentages

The salesman receives a 20% commission on all his sales.

One week the company pays $80 as commission.

This means that $80 corresponds to 20% of the sales.

To find the sales, we just divide the commission by the percentage (expressed as a decimal) as follows:

Sales = $80 / (20/100)

Sales = $80 / 0.20

Sales = $400

Thus, the sales of the week were $400
