Answer: Subtract 3 from each side
Step-by-step explanation:
The goal of the problem is to isolate 3 on one side by itself. The only thing standing in our way is that pesky three. In order to get rid of it, and make y have the whole left side to themselves, we have to see what is three doing in the equation. Well, it is a positive three and it is being added to y. So, we want to do the opposite of what it is. Since it is a positive three, we are going to subtract three on both sides. It will zero itself out on the left side and move on over to the right side, giving y the entire left side of the equation.
A square tile measuring 4 in. by 4 in. weighs 6 oz. Find the weight, in pounds, of a package of 144 such tiles.
Answer:
[tex]144 \ tiles = 864\ oz[/tex]
Step-by-step explanation:
Given
Dimension: 4 by 4
Weight: 6 oz
Required
Determine the weight of 144 of the tiles
From the question, we have that:
[tex]1\ tiles = 6\ oz[/tex]
Multiply both sides by 144
[tex]144 * 1\ tiles = 6\ oz * 144[/tex]
[tex]144 \ tiles = 864\ oz[/tex]
The length of the longer leg of a right triangle is 4ft more than twice the length of the shorter leg. The length of the hypotenuse is 6ft more than twice the length of the shorter leg. Find the side lengths of the triangle.
a. Find the length of the shorter side
b. Find the length of the longer side
c. Find the length of the hypotenuse
d. Find the side lengths of the triangle.
Answer: Shorter side = 10 feet
Longer side = 24 feet
Hypotenuse = 26 feet
The side lengths of the triangle are 10ft, 24ft and 26ft.
Step-by-step explanation:
Let the length of the shorter leg be x.
The length of the longer leg of a right triangle is 4ft more than twice the length of the shorter leg. This will be: = 2x + 4
The length of the hypotenuse is 6ft more than twice the length of the shorter leg. This will be: = 2x + 6
Note that the square of the hypothenuse will be equal to the square of the other two sides. This will be:
x² + (2x + 4)² = (2x + 6)²
x² + (2x + 4)(2x + 4) = (2x + 6)(2x + 6)
x² + 4x² + 8x + 8x + 16 = 4x² + 12x + 12x + 36
x² + 4x² + 16x + 16 = 4x² + 24x + 36
5x² + 16x + 16 = 4x² + 24x + 36
Collect like terms
5x² - 4x² + 16x - 24x + 16 - 36 = 0
x² - 8x - 20 = 0
x² - 10x + 2x - 20 = 0
x(x - 10) + 2(x - 10) = 0
Therefore, x - 10 = 0
x = 10
a. length of the shorter side = 10ft
b. Length of the longer side = 2x + 4 = 2(10) + 4 = 20 + 4 = 24ft
c. length of the hypotenuse = 2x + 6 = 2(10) + 6 = 20 + 6 = 26ft
d. The side lengths of the triangle are 10ft, 24ft and 26ft.

One leg of the picnic table in Ruth’s backyard is One-half of a centimetre too short, causing the table to wobble. Ruth grabs 3 quarters, each of which are 7 over 40 of a centimetre thick, for a total thickness of 21 over 40 to put under the table leg.
Which statement is true?
The 3 quarters are not thick enough to fill the gap because StartFraction 21 over 40 EndFraction is less than one-half.
The 3 quarters are not thick enough to fill the gap because 21 over 40 is greater than one-half.
The 3 quarters are too thick to put under the table leg because 21 over 40 is less than one-half.

Rosa spent $11.52 on 8 candy necklaces for each of her two friends. How much did each necklace cost?
A:0.72$
B:0.75$
C:0.89$
D:1.72$
Answer:
A. 0.72
Step-by-step explanation:
We take the amount spent on the necklaces and divide that by the amount she bought. So that would be $11.52/8. When we divide this, we get 1.44, and since this is not an option, I went and divided it by the two friends to get 0.72. So I believe A. would be the answer.
The cost for each necklace is given as $0.72.
How to calculate the cost per item?In order to calculate the cost of one item, divide the total cost of items by the total number of items.
It is also called the unit rate of that item.
Total money spent on 8 neckless is $11.52.
The number of friends Rosa has 2.
Then, total number of necklaces is 8 × 2 = 16
Now, the cost of each necklace can be calculated as,
Total cost of necklace ÷ Number of necklace
= $11.52 ÷ 16
= $0.72
Hence, the cost of each necklace for each of the friends is $0.72.

Hi, I just wanted to say that I got this question a few days ago on my test!
I haven't gotten my grade yet and I dont know if I got it right but I hope you figure it out! Best of luck to you!
The equation of a line in point slope form is :
Y - y1 = m(x -x1)
M is the slope given as 8
Y1 and x1 are the x and y values of the given point:
Y - (-6) = 8(x - (-3))
Rewrite as:
Y + 6 = 8(x + 3)

Solve the system of equations
Answer:
x = -2 and y = -21
Step-by-step explanation:
Given equations are :
[tex]y=15x+9\ .....(1)\\\\y=\dfrac{x}{2}-20\ ....(2)[/tex]
From equation (1) and (2)
[tex]15x+9=\dfrac{x}{2}-20\\\\15x-\dfrac{x}{2}=-20-9\\\\\dfrac{29x}{2}=-29\\\\x=-2[/tex]
Put the value of x in equation (1)
y = 15(-2) + 9
= -30 + 9
y = -21
So, the solution of the equations are (-2,-21).

Factor 343x^12 – 125y^27

Step-by-step explanation:

:
Equation at the end of step 1
73x3 - 27
STEP

:
Trying to factor as a Difference of Cubes:
2.1 Factoring: 343x3-27
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0-b3 =
a3-b3
Check : 343 is the cube of 7
Check : 27 is the cube of 3
Check : x3 is the cube of x1
Factorization is :
(7x - 3) • (49x2 + 21x + 9)
Trying to factor by splitting the middle term
2.2 Factoring 49x2 + 21x + 9
The first term is, 49x2 its coefficient is 49 .
The middle term is, +21x its coefficient is 21 .
The last term, "the constant", is +9
Step-1 : Multiply the coefficient of the first term by the constant 49 • 9 = 441
Step-2 : Find two factors of 441 whose sum equals the coefficient of the middle term, which is 21 .
-441 + -1 = -442
-147 + -3 = -150
-63 + -7 = -70
-49 + -9 = -58
-21 + -21 = -42
-9 + -49 = -58
For tidiness, printing of 12 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!

Step-by-step explanation:
Find the limit. Use l'Hospital's Rule where appropriate. If there is a more elementary method, consider using it. lim x → 0 x 8x 8x − 1
Answer:
1/log8
Step-by-step explanation:
Given the limit of the function
Lim x → 0 x•8^x/8^x − 1
Plug in the value of x
= 0•8^0/8^0-1
= 0(1)/1-1
= 0/0 (indeterminate)
Apply l'hosipitals rule:
Lim x → 0 d/dx(x•8^x)/d/dx(8^x − 1)
= Lim x → 0 (x•8^xlog8+1(8^x))/8^xlog8
Plug in the value of x:
= 0•8^0log8+8^0/8^0log8
= 0•1(log8)+1/1•log8
= 0(log8)+1/log8
= 0+1/log8
= 1/log8
Hence the limit of the function is 1/log8
