Answer:
y = 10
Step-by-step explanation:
Use the substitution method since you already know what x equals.
4y - 9(y - 3) = -23
Simplify:
4y - 9y + 27 = -23
Combine like terms:
-5y + 27 = -23
Isolate y by subracting 27 from both sides:
-5y = -50
Divide by -5 to get y by itself:
-5/-5 = y
-50/-5 = 10
Help me please! I'm stuck and I need the answer now! Thx so much!
Answer:
34Step-by-step explanation:
Given
z = -3 + 5iConjugate of z is:
z' = -3 - 5iProduct zz' is:
zz' = (-3 + 5i)(-3 - 5i) = (-3)² - (5i)² = 9 - 25(-1) = 9 + 25 = 34If ,
[tex]\bold{z=-3+5i }[/tex]
so,conjugate of z
[tex]\overline{ z }[/tex]=[tex]\bold{-3-5i }[/tex]
Because, in argand plane [tex]\overline{ z }[/tex] is the reflection of z in x-axis.
so,
According to the question,
z[tex]\overline{z}[/tex]=(-3+5i)(-3-5i)
[tex]\bold{(-3)^2-(5i)^2 }[/tex]
[tex]\bold{9-25(-1) }[/tex]
[tex]\bold{ 9+25 }[/tex]
[tex]\bold{ 34 }[/tex]

Answer:
1.06
Step-by-step explanation:

Sadie's sweets is having a sale on all their baked goods they are regularly priced at $4 but they are marked down to $2.6 what percent off are they
Answer:
35% off
Step-by-step explanation:
= |4 - 2.6|/((4 + 2.6)/2) = 1.4/3.3 = 0.42424242424242 = 42.424242424242%
Percentage of decrease = |4 - 2.6|/4 = 1.4/4 = 0.35 = 35%
2.6 is a 35% decrease of 4.

2. If m is inversely proportional to n, the equation must be written as
C. n= km
m
A. k=
n
k
B.m=-
n
D. none of the above
Answer:
mn = k
Step-by-step explanation:
Given that,
m is inversely proportional to n.
ATQ,
[tex]m\propto \dfrac{1}{n}[/tex]
or
[tex]m=\dfrac{k}{n}[/tex]
Cross multiplying both sides,
mn = k
Hence, the required equation is "mn=k".
Abigail’s parents pay her $5 an hour for weeding the yard and pay her little sister $3 an hour for raking leaves.
Write an expression in two different ways to represent the amount their parents will pay Abigail and her sister for working the same number of hours
I dont get help me
Answer: (MAKE ME BRAINLIST PLEASE)
Answer: For Abigail W = $5t
For her younger sibling W= $3t
Bit by bit clarification:
How about we address the compensation with W
t as the time spent on work in hours
Abigail will be paid $5 every hour, her all out compensation will be
W(abg) = $5t
Her younger sibling will be paid $3 every hour, her complete compensation will be
W(lts) = $3t

Step-by-step explanation:
how do i find the mean and median for this line of numbers?
42,51,64,55,51,54,51,69
Answer:
52.5
Step-by-step explanation:
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
The mean is 47.875 and the median is 51
Explanation:
To find the mean you have to add up all of the numbers together, and then divide that number (383) by how many numbers there are (8) so then you would get 47.875. Now you have to find the median. To find the median you have to place the numbers from the lowest to the greatest which would be 42, 51, 51, 51, 55, 64, 69. Then you basically just pick the number in the middle which is 51, so 51 is the median.
I need help- I’ll give brainlist if it’s right
Answer:
D. x>[4]
Plzzzzz give me Brainliest!!!!!
Answer:
D. x > 4
Step-by-step explanation:
You have to do the opposite operations to get the variable on one side of the equation by itself.
4 - x + 4 = 8 - 4
x = 4
You only switch the comparison sign if you mutliply or divide by negative numbers when you do opposite operations to get the variable on one side of the equation by itself.
I hope this helps!

The net of a right rectangular prism is shown below. The measurements are given to the nearest tenth of a centimeter. What is the surface area of the prism?
Answer: c. 352.50 cm²
Step-by-step explanation:
Looking at the shape one can see that it is made up of 3 rectangles and 2 triangles.
The surface area will therefore be the sum of the areas of these 5 shapes.
Rectangle area = Length * width
= 7.5 * 13.5
= 101.25 cm²
There are 3 of them:
= 101.25 * 3
= 303.75 cm²
Triangles = 1/2 * base * height
= 1/2 * 7.5 * 6.5
= 24.375 cm ²
There are two of them:
= 24.375 * 2
= 48.75cm²
In total:
= 303.75 + 48.75
= 352.50 cm²
