The value of x according to the equation is -7/4 and the equivalent equations that Katrina might use is x - 2x - 6 = 8x + 12 - x - 4
Given the equation solved by Katrina expressed as;
x - 2 (x + 3) = 4 (2 x + 3) - (x + 4).
Expand using distributive law;
x - 2x - 6 = 4(2x) + 4(3) - x - 4
x - 2x - 6 = 8x + 12 - x - 4
-x - 6 = 7x + 8
-x - 7x = 8 + 6
-8x = 14
x = 14/-8
x = -7/4
Hence the value of x according to the equation is -7/4 and the equivalent equations that Katrina might use is x - 2x - 6 = 8x + 12 - x - 4

Ashton read 12 pages on Friday. He read 3 times as many pages on Saturday, and 14 more pages on Sunday.How many more pages did Ashton read over the three days?
Answer:
Ashton read 62 pages over the three days
Step-by-step explanation:
Given;
Ashton read 12 pages on Friday
He read 3 times as many pages on Saturday = 3 x 12 pages = 36 pages
He read 14 more pages on Sunday
The total number of pages read Ashton over the three days can be calculated as follows;
Total pages read by Ashton = 12 pages + 36 pages + 14 pages
Total pages read by Ashton = 62 pages
Therefore, Ashton read 62 pages over the three days

The sand box is is going to have the shape and dimensions below. If the diagonal of the sandbox measures 14 feet, what kind of quadrilateral will the sandbox be? Explain how you know.
Answer:
we know that
applying the Pythagoras Theorem
c²=a²+b²
where
c=14 ft
a=8 ft
b=12 ft
case a)
if
c²=a²+b² C is a right angle
case b)
if
c²< (a²+b²) C is an acute angle
case c)
if
c² > (a²+b²) C is an obtuse angle
c²=14² 196
(a²+b²)=8²+12² 208
196 < 208
c² < (a²+b²) C is an acute angle
the answer is the option
C. a quadrilateral, because angle C and angle X are acute

5(x-4)+3x-9x+7
step 1: rewrite the subtraction operations as addition of negative numbers.
step 2: use the distributive property.
step 3: use the commutative property of addition to reorder terms so that like terms are together.
step 4: use the associative property of addition to group like terms.
step 5: simplify.
Answer:
x = -27
Step-by-step explanation:
Apply the Distributive Property to 5(x - 4): 5x - 20.
Then we have 5x - 20 + 3x - 9x + 7.
Combining like terms, we get -x = 7 + 20 = 27, so that x = -27.

Mike buys three cans of pop per week. This is one more than two fifths the number of cans of juice Mike buys per week. Determine the number of cans of juice Mike buys per week.
Answer:
5
Step-by-step explanation:
Mike buys 3 cans of pop per week and this is one more than 2/5 of the number of cans of juice that he buys.
Let the number of cans of juice be j and let the number of cans of pop be buys be p.
This means that:
p = 1 +2j/5
Make j subject of formula:
p - 1 = 2j/5
=> 2j = 5p - 5
j = ½(5p - 5)
p = 3 (from the question)
Therefore:
j = ½(5 * 3 - 5) = ½(15 - 5)
j = ½ * 10 = 5
Mike buys 5 cans of juice per week.
Solve for x. 3x/6 + 2 = 8
Answer:
x = 12
Step-by-step explanation:
Given
[tex]\frac{3x}{6}[/tex] + 2 = 8 ( subtract 2 from both sides )
[tex]\frac{3x}{6}[/tex] = 6 ( multiply both sides by 6 )
3x = 36 ( divide both sides by 3 )
x = 12

Step-by-step explanation:
[tex] \frac{3x}{6} + 2 = 8 \\ collect \: like \: terms \\ [/tex]
[tex] cross \: multiply \\ \frac{3x}{6} = \frac{6}{1} \\ 3x = 6 \times 6 \\ 3x = 36[/tex]

In triangle MNP, medians NQ and PR intersect at S. If PS = 8 and QS = 3 then which of the following is the value of NQ + PR
(1) 21
(2) 22
(3) 26
(4) 30
Answer:
(2) 22
Step-by-step explanation:
In the given triangle MNP, the medians are straight lines drawn from the angle to opposite side so as to divide the side into equal parts.
PS = 8 and QS = 3, thus;
PS = NS = 8 (congruent property of ΔRSN and ΔQSP)
QS = SP = 3 (congruence property)
So that,
NQ = NS + SQ
= 8 + 3
= 11
PR = PS + SR
= 8 + 3
= 11
Thus;
NQ + PR = 11 + 11
= 22
Therefore, NQ + PR = 22

Answer:
It depends.
Step-by-step explanation:
For 6 years:
[tex]50000*(1.04)^6=\$63266[/tex]
On average, you would have to be profiting:
[tex]\frac{63266}{6}=\$10544[/tex] per year
For 4 years:
[tex]50000*(1.04)^4=\$58492[/tex]
On average, you would have to be profiting:
[tex]\frac{58492}{4} = \$14623[/tex] per year.
It would be better to have the longer term option - although you will be paying off more in total, you would be paying off a smaller portion of your earnings.
However, you may want to pay off the loan faster as you would no longer have to worry about it, and it would be cheaper to pay off over the shorter period.
A Cepheid star is a type of variable star, which means its brightness is not constant. The relationship between the brightness of a

Step-by-step explanation:
not too sure sorry
Answer:
184
Step-by-step explanation:
y + j + p + a = 1026
y - 60 = j/4 -------> y = (j/4) + 60
p + 150 = j/2 -----> p = (j/2) - 150
2a = j -------> a = j/2
y = ?
y + p + j + a = 1026
(j/4) + 60 + (j/2) - 150 + j + (j/2) = 1026
(j/4) + j + j - 90 = 1026
(j/4) + 2j = 1116
9j/4 = 1116
9j = 4464
j = 496
y = (496/4) + 60 = 184

A box measures 4 units by 2 and 1/2 units, by 1 and 1/2 units. What is the greatest number of cubes with a side length of 1/2 unit that can be packed inside the box?
Answer:
120 cubes
Step-by-step explanation:
First we need to find the volume of the box and the volume of the cube.
Volume of box = 4 * 2.5 * 1.5 = 15 cubic units
Volume of cube = 0.5 * 0.5 * 0.5 = 0.125 cubic units
Now, to find how many cubes can be packed inside the box, we just need to divide the volume of the box by the volume of the cube:
number of cubes = volume of box / volume of cube
number of cubes = 15 / 0.125 = 120 cubes
The width of a rectangle is the length minus 3 units. The area of the rectangle is 10
units. What is the width, in units, of the rectangle?
Answer:
w=2
Step-by-step explanation:
A=length times width (A=lw)
w= l-3
A=10
Substituting in, we get:
10= l(l-3)
Now, solve the equation.
10= [tex]l^{2}[/tex]-3l
[tex]l^{2}[/tex]-3l-10=0
(l+2) (l-5)=0 (factoring the equation)
Therefore, l= -2 or 5
Throw out the negative value because a length of rectangle will never be negative.
Now let's solve for width
Remember w=l-3
therefore
(5)-3=2
so, w=2
