Answer:
x = 7/12
Step-by-step explanation:
20 = 15(x + 3/4) (Given)
20 = 15x + 45/4 (Distribute)
35/4 = 15x (Subtract 45/4 on both sides)
7/12 = x (Divide 15 on both sides)
You can substitute the solution for x to check.
20 = 15(7/12 + 3/4)
20 = 15(4/3)
20 = 20

If a rectangle piece of dimensions 3 cm x 2 cm is cut from one corner of a rectangular sheet of dimensions 10 cm x 6 cm and attached to it's side projecting out of the rectangle, what will be the change in perimeter of the new shape thus formed?
Answers
Answer:
[tex]6\ \text{cm}[/tex]
Step-by-step explanation:
The sides of the larger rectangle are 10 cm and 6 cm.
The sides of the part cut out are 3 cm and 2 cm.
The part cut out is attached to one of the sides of the rectangle.
Perimeter of the new shape will be
[tex]6+7+2+3+2+3+2+13=38\ \text{cm}[/tex]
Perimeter of old shape
[tex]2(10+6)=32\ \text{cm}[/tex]
Change in the perimeter is [tex]38-32=6\ \text{cm}[/tex]
The perimeter of changed by [tex]6\ \text{cm}[/tex].

Answers
Answer:
4 W
Step-by-step explanation:
Electrical power, P = I²R where I = current and R = resistance.
Given that I = 0.2 A and R = 100 Ω,
P = I²R
P = (0.2 A)² × 100 Ω
P = 0.04 A² × 100 Ω
P = 4 W

Rewrite the equation in slope intercept form
3y - 8x = -9
Answers
Answer:
y = (8/3)x - 3
Step-by-step explanation:
To get to slope intercept, just solve for y
3y - 8x = -9
3y = -9 + 8x
y = (-9 + 8x)/3
y = -9/3 + 8x/3 (distribute the 3 so we can reach the right form)
y = -3 + 8/3(x)
finally write in slope intercept form:
y = (8/3)x - 3

Find the length and width of a rectangle.
Perimeter = 50
Side A = 3x + 2
Side B = x - 5
Answers
Step-by-step explanation:
Perimeter = 2 * (Side A + Side B)
= 2 * (3x + 2 + x - 5)
= 2 * (4x - 3)
= 8x - 6.
We have 8x - 6 = 50, so 8x = 56 and x = 7.
Length of rectangle = 3(7) + 2 = 23.
Width of rectangle = (7) - 5 = 2.
Answer:
Length of rectangle = 3(7) + 2 = 23.
Width of rectangle = (7) - 5 = 2.

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.
