Simplifying 6p + 2(4 + -2p) = 3(p + 4) 6p + (4 * 2 + -2p * 2) = 3(p + 4) 6p + (8 + -4p) = 3(p + 4) ... Move all terms containing p to the left, all other terms to the right. ...

Levi invests money in an account paying a simple interest of 8.7% per year. If he invests $70 and no money will be added or removed from the investment, how much will he have in one year, in dollars and cents?
Answer:
Pn=Po(1+r)^n
r=8.7%=8.7/100=0.087
Po=$70
n=1
P1=70(1+0.087)^1
=70(1.087)=76.09
=76
Answer:$76.09
Step-by-step explanation:
100%+8.7%=
108.7%\,\,108.7\%108.7%
Whole balance before interest = 100%, then add on interest
108.7% of the current balance means 108.7100 of it.\text{108.7\% of the current balance means \(\frac{108.7}{100}\) of it.}108.7% of the current balance means 100108.7 of it.
"Percent" literally means "out of 100."
108.7100=\frac{108.7}{100}=100108.7=
1.087\,\,1.0871.087
To find 108.7% of the current balance, multiply by 1.087:\text{To find 108.7\% of the current balance, multiply by \(1.087\):}To find 108.7% of the current balance, multiply by 1.087:
$70×1.087=\$70\times1.087=$70×1.087=

1. Kristen spent $131 on shirts at Target last week. She bought some fancy shirts for
$28 each and then some plain t-shirts for $15 each. If she bought a total of 7 shirts,
then how many of each type of shirt did she buy?
problem #1
problem #2
Answer:
Kristen bought 2 fancy shirts and 5 plain t-shirts.
Step-by-step explanation:
Given that,
Kristen spent $131 on 7 shirts.
Cost of one fancy shirt = $28
Cost of one plain t-shirt = $15
Let,
x be the number of fancy shirts
y be the number of plain t-shirts
x+y = 7 Eqn 1
28x+15y=131 Eqn 2
Multiplying Eqn 1 by 15
15(x+y=7)
15x+15y=105 Eqn 3
Subtracting Eqn 3 from Eqn 2
(28x+15y)-(15x+15y)=131-105
28x+15y-15x+15y=26
13x=26
Dividing both sides by 13
[tex]\frac{13x}{13}=\frac{26}{13}\\x=2[/tex]
Putting x=2 in Eqn 1
2+y=7
y=7-2
y=5
Hence,
Kristen bought 2 fancy shirts and 5 plain t-shirts.

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.
Answer:
18x - 36
Step-by-step explanation:
In an equilateral triangle the 3 sides are congruent, then
perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms
= 18x - 36
The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
As we know in an equilateral triangle the 3 sides are congruent.
The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12
Combine the likewise terms and we get
The perimeter of the triangle = 18x - 36
Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

Describe a sequence of transformations that maps Figure A to Figure B.
A. A 270° rotation about the origin, and then a dilation of 2 with center (0,0)
B. A 270° rotation about the origin, and then an expansion of 2 with center (0,0)
C. A 90° rotation about the origin, and then an expansion of 2 with center (0,0).
D. A 90° rotation about the origin, and then a dilation of 2 with center (0,0)
A sequence of transformations that maps Figure A to Figure B are: A 90° rotation about the origin, and then an expansion of 2 with center (0,0).
The correct answer is an option (C)
What is transformation?"It means changing the size and position of an object from its original position to a new position."
What is rotation?"It is a transformation that turns a figure about a fixed."
For given example,
We need to describe the transformation that maps Figure A to Figure B.
First we rotate figure A by 90° about the origin.
We can observe that the size of the figure B is larger than the figure A.
So, after rotation we expand figure A by 2 units.
Therefore, a sequence of transformations that maps Figure A to Figure B are: A 90° rotation about the origin, and then an expansion of 2 with center (0,0).
The correct answer is an option (C)

what is an equation of the line that passes through the points 0,-1 and 6,1
put answer in fully reduced form
Answer: x - x1/ x2- x1 = y -y1 / y2-y1
x - 6/ -6-6= y - 1/ -1 -1
x -6/-12 = y -1 /-2
-2(x-6) = -12 (y-1)
-2x +12 = -12y +12
12y = 2x +12-12

Answer:
Saturday: 1.5x
Sunday: 2x
Step-by-step explanation:
For the the Chart, Saturday, we can automatically see that when 1 is inputted into the equation we get 1.5, as anything times 1 will equal the same number inputted (x). So we can try 1.5x and plug in every other x value and see what we get:
1.5(2) = 3
1.5(3) = 4.5
1.5(4) = 6
This verifies that the equation 1.5x works with this chart.
For the graph its simple, do rise over run and your slope is 2/1 which is 2 so we have 2x for our equation so far and now to find the + or - at the end of the equation ( the "b" variable of the mx + b form) we just look at where does the function intersect with the Y-axis. Since it is at 0 we don't need to add a "b" variable to the equation so the equation for the graph is 2x for Sunday.
what is the period of the sinusoidal function
Answer:
10Step-by-step explanation:
Period is the distance between two consecutive maximum points, or two consecutive minimum points.On the given graph the period is the distance between maximum points -7 and 3:
3 - (-7) = 10Answer:
The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.
From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units
Therefore, 10 units is the right answer.
4(x-2)/5 = 20
(Yes that’s a fraction)
Solving for x
Answer:
x=27
Step-by-step explanation:
Step 1: Multiply both sides by 5.
4(x−2)
5=20
(4(x−2)*(5)*(5)=(20)*(5)
4(x−2)=100
Step 2: Simplify both sides of the equation.
4x−8=100
Step 3: Add 8 to both sides.
4x−8+8=100+8
4x=108
Step 4: Divide both sides by 4.
4x/4=108/4
x=27
Step-by-step explanation:
(x-2)/5 = 5
(x-2) = 25

5th grader question
help asap
30 points!
Answer:
7.770
Step-by-step explanation:
Amelie originally wrote her number with only two decimal places, 7.77. This only includes the tenths and hundredths places. In order to have one more decimal place, she needs to add a zero after the last digit. Therefore, her number should be written as "7.770" because this consists of a thousandths place. With this number, she can then compare her number to Matthew's 7.707.
7.707 ∠ 7.770We can conclude that Matthew's number is less than Amelie's number.
