141 recordsStep-by-step explanation:
Let the initial number be x
Sold 1/3x, and now has:
x - 1/3x = 2/3xBought 84 more and now got 178:
2/3x + 84 = 1782/3x = 94x = 94 ÷ 2/3x = 94 × 3/2x = 141Jessica had 141 records initially

Pip was thinking of a number. Pip doubles it, then adds 6 to get an answer of 13.8. What was
the original number?
Answer:
The original number is 3.9.
Step-by-step explanation:
With the information given, you can write an expression where the number multiplied for 2 plus 6 is equal to 13.8:
2x+6=13.8, where x is the original number
Now, you can solve for x to find the original number:
2x=13.8-6
x=7.8/2
x=3.9
According to this, the answer is that the original number is 3.9.

don't know just say it and the end of your answer -The two plots compare the top 25 home run hitters in 2007 with those in 2008. Which choice is NOT true?
Answer:
It is the top right one.
Step-by-step explanation:
A linear function is expressed by a graph of a line that
crosses both axes at the origin. An equation is written in
siope-intercept form to express the same function as
shown in the graph From just this information what
statements can be made?
Choose the true statements
The slope of the equation must be positive.
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
The slope of the equation must be negative
Answer:
The y-intercept of the equation is zero. It is possible that the line on the graph is horizontal.
Step-by-step explanation:
Answer:
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
Step-by-step explanation:
The only thing we know for sure is that the function goes through the point (0,0). The line y = 0 passes through (0,0), so it is possible that the line on the graph is horizontal. Since x = 0 where y = 0, the y-intercept is also 0. However, we have no way of knowing for sure what the slope of the equation is.
the graph is _ throughout its domain and has _ at the x-axis because the value bx can get very close to 0 but never reach it

The difference of two complementary angles is 20. Find the measure of each angle
Answer:
35° , 55°
Step-by-step explanation:
Let one angle be x.
It's complementary angle is = (90 - x)°
According to the question ,
[tex]x - (90 - x) = 20[/tex]
[tex]=> x - 90 + x = 20[/tex]
[tex]=> 2x = 90 - 20 = 70[/tex]
[tex]=> x = \frac{70}{2} = 35[/tex]
assume that y varies directly as x. If y= -15 when x=5, what is the constant of variation?
Answer:
k = -3
Step-by-step explanation:
Given
Variation: Direct
y = -15 when x = 5
Required
Find the constant of variation
A direct variation is represented as:
y = kx
Where
k = constant of variation
Substitute values for x and y
-15 = k * 5
Multiply both sides by ⅕
⅕ * -15 = k * ⅕ * 5
-3 = k * 1
-3 = k
k = -3
Hence, the constant of variation is -3

If k is a constant, what is the value of k such that the polynomial 2ky^-kx-8 is divisible by (x-2)
Answer:we have that
k² x³-6kx+9
we know that
The Remainder Theorem says: If the polynomial f(x) is divisible by a bynomial (x-a) then the number "a" is a root of the polynomial f(x)
so
x=1 is a root of the polynomial
therefore
for x=1
k² x³-6kx+9=0--------> k² (1)³-6k(1)+9=0-----> k²-6k+9=0
using a graph tool------> to resolve the second order equation
the solution is
k=3
k=3
k²-6k+9=0---------> (k-3)²=0
the answer is
k=3
Answer:
Ok so if I did this right the answer will be 2ky^kx-8 / x -2

What expression has the same value as 27+36
Answer:
its 3x9+13
Step-by-step explanation:
x
The expression 27+36 as be written as: 9(3+12)
What is expression?An expression is a set of terms combined using the operations +, – , x or for example 4 x − 3 or x 2 – x y + 17 .
An equation states that two expressions are equal in value,
for example 4 b − 2 = 6 .
We have: 27+36
Prime factorise both the numbers:
27=3*3*3
36= 2*2*3*3
So,
27+36
=3*3*3+2*2*3*3
= 3*(3*3+2*2*3)
=9(3+12)
Hence, The expression 27+36 as be written as: 9(3+12)

27.) Find the sum of the length of line segments EF and CD
Answer:
5√10
Step-by-step explanation:
The distance between two points A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) on the coordinate plane is given by:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 }[/tex]
From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).
Hence the lengths of the line segment EF and CD are:
[tex]|EF|=\sqrt{(8-(-1))^2+(-4-(-1))^2} =\sqrt{90}=3\sqrt{10} \\\\CD=\sqrt{(-1-(-7))^2+(-2-(-4))^2}=\sqrt{40} =2\sqrt{10} \\\\Therefore:\\\\|EF|+|CD|=3\sqrt{10} +2\sqrt{10} =5\sqrt{10}[/tex]

Which expression is equal to c2−4c+412c3+30c2÷c2−46c4+15c3?
Answer
A: c (c-2)/ 2 (c +2)
Step-by-step explanation:
Which is equal to c^2-4c+4/ 12c^3+ 30c^2 divided by c^2-4/ 6c^4 +15c^3?
A: c (c-2)/ 2 (c +2)
B: 2 (c-2)/ c(c+2)
C: 2 (c+2)/ c(c-2)
D: c(c+2)/ 2(c-2)
[c^2 - 4c + 4] / [12×(c^3) + 30×(c^2)] ÷ [c^2 - 4] / [6×(c^4) +15×(c^3)]
Expand the expression
= [c^2 - 2×2×c + 2^2] / [6×(c^2)×(2c + 5)] ÷ [c^2 - 2^2] / [3×(c^3)×(2c +5)]
Factorize the expression
= [(c-2)^2] / [6×(c^2)×(2c + 5)] ÷ [(c-2)(c+2)] / [3×(c^3)×(2c +5)]
Multiply by interchanging the numerator and denominator of the divisor
= [(c-2)^2] / [6×(c^2)(2c + 5)] × [3(c^3)(2c +5)] / [(c-2)(c+2)]
= [(c-2)×3(c^3)] / [6×(c^2)×(c+2)]
= [c×(c-2)] / [2×(c+2)]
= c(c - 2) / 2(c + 2)
[c^2 - 4c + 4] / [12×(c^3) + 30×(c^2)] ÷ [c^2 - 4] / [6×(c^4) +15×(c^3)] = c(c - 2) / 2(c + 2)
Answer:
A: [tex]\frac{c(c-2)}{2(c+2)}[/tex]
Step-by-step explanation:
[tex]\frac{c^{2} -4c+4}{12c^{3} + 30c^{2}}[/tex] ÷ [tex]\frac{c^{2} -4}{6c^{4} + 15c^{3}}[/tex]
expand.
= [c^2 - 2×2×c + 2^2] / [6×(c^2)×(2c + 5)] ÷ [c^2 - 2^2] / [3×(c^3)×(2c +5)]
factorize.
= [(c-2)^2] / [6×(c^2)×(2c + 5)] ÷ [(c-2)(c+2)] / [3×(c^3)×(2c +5)]
multiply by the reciprocal.
= [(c-2)^2] / [6×(c^2)(2c + 5)] × [3(c^3)(2c +5)] / [(c-2)(c+2)]
= [(c-2)×3(c^3)] / [6×(c^2)×(c+2)]
= [c×(c-2)] / [2×(c+2)]
= A: [tex]\frac{c(c-2)}{2(c+2)}[/tex]
