Answer:
12
Step-by-step explanation:
perimeter is (a+b) x 2 = 46
a is width and b is length
a=11
(11+b) x 2 = 46
22 + 2b = 46
2b = 24
b = 12 ( length )
Solution:
We know that:
Width of rectangle = 11 inchesPerimeter of rectangle = L + B + L + B = 2L + 2BSubstitute the width in the expression:
2L + 2B = Perimeter2L + 2(11) = 46 inSimplify the LHS:
2L + 22 = 46 inSubtract 22 both sides:
2L = 46 - 222L = 24Divide 2 both sides:
2L/2 = 24/2L = 24/2 = 12 inEstimate. 110×298

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

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:
7 42
___ = ____
2 12
42/12
The answer is [tex]\frac{42}{12}[/tex]
First, you must simplify both sides if the equation.
[tex]\frac{7}{2}=\frac{x}{12}[/tex]
Then, multiply both sides by 12
[tex]42=x[/tex]
[tex]x=42[/tex]
Finally, substitute in 42 for x
[tex]3\frac{1}{2}=\frac{42}{12}[/tex]
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
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.

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.

Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

pose that the function f(x) - 5.32 +0.80x represents the cost of mailing an
ect that weighs x pounds. How much would it cost to mail an object that
ghs 36 pounds?
te: express the answer in dollars.cents)
Answer:
$34.12Step-by-step explanation:
The expression for the total cost of a mail is given as
f(x) - 5.32 +0.80x, where x is the amount of weight in pounds
Given that x= 36 pounds we can find the cost of mailing 36 pounds of ect
hence let us put x=36 in the expression to find the total cost
f(x) =5.32 +0.80(36)
f(x) =5.32 +28.8
f(x) =34.12
Therefore the cost of mailing 36 pounds of ect is $34.12
