6) Maria bought seven boxes. A week later
half of all her boxes were destroyed in a fire.
There are now only 22 boxes left. With
how many did she start?
please helppp
Answer:
37 boxes
Step-by-step explanation:
you should try and write each of the steps into an equation of x. Where x is the boxes she started with
so, she had x boxes, she bought 7 (that's addition) and then half of those boxes (that's division) got destroyed in the fire and she has 22 left (that's your total).
you can write the equation like this:
(x+7)/2 = 22
then, you solve
(x+7) = 44
x = 37
she originally had 37 boxes
The price of a share of stock started the day at $19. During the day it went down $13 up $1, and down $14 and up $4. What integer represents the price of a share at the end of the day.
Answer:
-3
Step-by-step explanation:
19-13=6+1=7-14=-7+4=-3
The integer represents the price of a share at the end of the day will be negative 3.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The price of a share of stock started the day at $19. During the day it went down $13 up $1, down $14, and up $4.
Then the integer represents the price of a share at the end of the day will be
⇒ 19 - 13 + 1 - 14 + 4
⇒ -3
The integer represents the price of a share at the end of the day will be negative 3.

Answer:
y = x + 5
Step-by-step explanation:
Find any two points:
(1, 6)
(2, 7)
Slope = (y2 - y1) / (x2 - x1)
S0:
7 - 6 / 2 - 1
1 / 1
So slope = 1
Equation:
y = mx + b
Plug in the numbers using the x and y of any points:
7 = m * 2 + b
Add m (which is the slope):
7 = 1 * 2 + b
7 = 2 + b
Subtract two from both sides:
5 = b
So our equation is:
y = x + 5
Please let me know if I've done anything wrong!
Answer:
y = x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 5) ← 2 points on the line
m = [tex]\frac{5-0}{0+5}[/tex] = [tex]\frac{5}{5}[/tex] = 1
The line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = x + 5 ← equation of line

Damon was on his way to a marble tournament when he met Artemio. Damon's bag of marbles was heavy, so he gave Artemio ½ of his marbles plus 2. Then he met Banou and gave her ¼ of his remaining marbles plus 5. Just before arriving at the tournament, he met Alex and gave him ½ of the marbles he had left. When he got to the tournament, he had 2 marbles left. How many marbles did he start with?
Answer: 28.
Step-by-step explanation:
Let's define D = # of marbles in Damon's bag at the beginning.
First, he gave D/2 + 2 marbles to Artemio, so now he has:
(D - D/2 - 2) = (D/2 - 2) marbles left.
Now, he gives 1/4 plus of what he has left plus 5 to Banou, so he gives:
(D/2 - 2)/4 + 5 marbles to Banou.
Then Damon has now:
(D/2 - 2) - (D/2 - 2)/4 - 5 = 3*(D/2 - 2)/4 - 5.
Now Damon gives half of this to Alex, then the amount that he has left is:
(3*(D/2 - 2)/4 - 5)/2
And we know that this is equal to 2, then we can solve this equation as:
(3*(D/2 - 2)/4 - 5)/2 = 2
Let's solve this for D.
(3*(D/2 - 2)/4 - 5) = 2*2 = 4.
3*(D/2 - 2)/4 = 4 + 5 = 9
3*(D/2 - 2) = 9*4 = 36
(D/2 - 2) = 36/3 = 12
D/2 = 12 + 2 = 14
D = 2*14 = 28
Damon initially had 28 marbles.

A linear function is given by formula y= 1/2x - 2
What is the x-intercept of the graph?
Answer:
see below
Step-by-step explanation:
y= 1/2x - 2
To find the x intercept, set y =0 and solve for x
0= 1/2x - 2
Add 2 to each side
2 = 1/2x -2+2
2 = 1/2x
Multiply by 2
2*2 = 1/2x *2
4 =x
The x intercept is 4

What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given:
The equation is
1 – (2x + 4) = –4x + 5,
we have to find the correct solution of the equation;
According to given question we have,
Step 1: Open the parenthesis we get,
1 – (2x + 4) = –4x + 5
1-2x-4 = -4x + 5
1-4-2x = -4x +5
-3-2x = -4x + 5
Step 2: Collect like terms we get,
-2x + 4x = 5 + 3
2x = 8
Step 3: divide both sides by 2 we get,
2x/2 = 8/2
x = 4
Hence the correct value of x is 4.

The sum of the squares of the two consecutive multiples of 7 is 637. Write the
equation that characterizes this multiples.
Answer:
The first multiple of 7 = 14 or -21
The second multiple of 7 = 21 and -14
Step-by-step explanation:
Let
The first multiple of 7 = 7x
The second multiple of 7 = 7(x+1)
Square of the first multiple = (7x)^2
Square of second multiple = {7(x+1)}^2
Sum
(7x)^2 + 7(x+1)}^2 = 637
49x^2 + 49(x+1)^2 = 637
Divide through by 49
x^2 + (x+1) = 13
Open bracket
x^2 + x^2 + 1 + 2x = 13
Subtract 13 from both sides
x^2 + x^2 + 1 + 2x - 13 = 13 - 13
x^2 + x^2 + 1 + 2x - 13 = 0
2x^2 + 2x - 12 = 0
Divide through by 2
x^2 + x - 6 = 0
Solve the quadratic equation using factorization method
x^2 + 3x - 2x - 6 = 0
x(x+3) - 2(x+3) = 0
(x - 2) (x+3) = 0
x - 2 = 0
x = 2
x+3 = 0
x = -3
Substitute x = 2 or -3 into 7x
When x= 2
7(2) = 14
When x = -3
7(-3) = -21
The first multiple of 7 = 14 or -21
Substitute x = 2 or -3 into 7(x+1)
When x= 2
7(2+1) = 7(3) = 21
When x = -3
7(-3+1) = 7(-2) = -14
The second multiple of 7 = 21 and -14
Vertical line q goes through plane H in the center at point X. Line t comes out of point X. Lines r and s are parallel and are at a right angle to line q. Line p goes through lines r and s. Which line is parallel to line r? line p line q line s line t
Answer:
Option C: Line s
Step-by-step explanation:
Let's refer to plane H as being 2D since we are dealing with lines.
Thus, x-axis would refer to the horizontal axis while y-axis will refer to the vertical axis.
Now, we are told that line q goes through plane H in the center at point X and that Line t is one that comes out from point X.
This means that line q and line t are parallel to each other.
Also, we are told that Lines r and s are parallel and that they're at a right angles to line q.
Since line q and line t are parallel to each other, it means that lines r and s are at right angles to both lines q and t
Thus, it means lines r and s are both perpendicular to lines q and t
Now, we are told that line p goes through r and s.
However, we want to find which line is parallel to line r.
From earlier statement we saw that lines r and s are parallel to each other.
Thus; correct answer is "line s"
Answer:
C

3 1/2 as an equivalent fraction with a denominator equal to 12
Answer:
42/12
Step-by-step explanation:
3 1/2 in improper fraction form is 7/2. We can see the denominator in the equivalent fraction is 12. In order for that to happen, the common factor that must have been multiplied is 6. So the numerator of the equivalent fraction should be 42 because:
