Answer: 7w+7=-4+4w+23 = W = 4
First you have to simplify the equations
7w+7= (4w) + (-4+23) 7w+7= 4w+19
Than you have to subtract the 4w (both equation)
7w+7-4w =4w = 4w + 19 - 4w = 3w+7= 19
And than you have to subtract the sevens
3w+7-7=19-7=3w=12
than divide by 3
3w/3 equals 12/3w=4

12x+8y=240
How do I solve for y ?
A relation between a collection of inputs and outputs exists comprehended as a function.
If the equation be 12x + 8y = 240 then the value of y exists 30 - (12x/8).
What is meant by function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A relation between a collection of inputs and outputs exists comprehended as a function.
Let the equation be 12x + 8y = 240
8y = 240 - 12x
simplifying the above equation, we get
y = (240 - 12x) / 8
y = 30 - (12x/8)
Therefore, the value of y = 30 - (12x/8).

Hey there!
The given points are; (-4,-1) and (4,2).
Use slope formula.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{2 + 1}{4 + 4} [/tex]
Simplify it.

The ratio of adult cats to kittens at a pet care center on was 5:2 . There were 12 kittens there that day. Thursday , 38 adult cats were at the pet care center. What is the difference between the number of adult cats at the pet care center on thursday and monday?
Answer:
8 adult cats
Step-by-step explanation:
The ratio of adult cats to kitten at the pet care center was 5:2
No of adult cats= 5x
No of kitten cats= 2x
Since there were 12 kittens that day
2x= 12
x= 12/2
x= 6
Number of adult cats = 5x
= 5 × 6
= 30 adult cats
Therefore since there were 38 adult cats in the pet center in Thursday then the difference between the number of adult cats in Thursday and Monday can be calculated as follows
= 38-30
= 8 adult cats

Answer:
I am pretty sure the last one is correct
The table that represents a linear function is:
x---y
0---1
1---2
2---4
3---8
Here, we have,
from the given tables, we get, the information that,
from the 1st table, we get,
x---y
0---1
1---2
2---4
3---8
In this table, the y-values increase by a constant difference of 1 as the x-values increase by a constant difference of 1.
This indicates a linear relationship between x and y, where the y-value is twice the x-value.
but, in the other tables, we can't get any linear relationship between x and y.
so, we get,
The table that represents a linear function is:
x---y

Find a counterexample for the given conjecture.
The difference of two odd numbers is always an odd number.
Answer:
The difference of two odd number is always even as seen below.
Step-by-step explanation:
First odd number = x
Second odd number = x + 2
Third odd number = x + 4
Therefore
(x + 4) - (x + 2) = x
Where x is any odd number
Using 1 :
(1 + 4) - (1+2)
5 - 3 = 2
2 is not an odd number
We can say the difference of two odd number is always even
The length and breadth of a rectangle are in a 15 : 11 ratio. If the length is 56 cm more than the breadth, find the perimeter of the rectangle.
Answer:
g
Step-by-step explanation:
Answer:
Perimeter of rectangle = 728 cm
Step-by-step explanation:
Length : breadth = 15 : 11
Length = 15x
Breadth = 11x
15x - 11x = 56 cm
4x = 56
x = 56/4
x = 14
Length = 15 *14 = 210 cm
Breadth = 11 * 14 = 154 cm
Perimeter of rectangle = 2 * ( length + breadth)
= 2 *(210 + 154)
= 2 * 364
= 728 cm

Combine like terms.
Subtract 6 from both sides.
Use the quadratic formula to solve for x.
Step-by-step explanation:
Given:
-x (-3 + x )2 = 6

-6x + 2x^2 = 6
2x^2 - 6x - 6 = 6 - 6
2x^2 - 6x - 6 = 0
Multiply -3 by 2.
Multiply x by 2.
Combine like terms.
Subtract 6 from both sides.

The frequency distribution shows the number of registered motor vehicles for a random sample of 200 California households.
(a) Find the mean number of registered vehicles per California household.
Answer:
____vehicles
(b) Find the median number of registered vehicles per California household.
Answer:
___vehicles
Answer:
1). Mean = 2.275
2). Median = 2 vehicles
Step-by-step explanation:
From the given table,
Number of vehicles (x) Frequency (f) (f)×(x) Cumulative freq.
0 11 0 11
1 52 52 63
2 66 132 129
3 35 105 164
4 19 76 183
5 12 60 195
6 5 30 200
[tex]\sum (f\times x) = 455[/tex]
Number of households = 200
Mean = [tex]\sum \frac{f.x}{n}[/tex]
= [tex]\frac{455}{200}[/tex]
= 2.275
Median = value of [tex]\frac{(n+1)}{2}th[/tex] observation
= value of [tex]\frac{201}{2}th[/tex] observation
= Value of 100.5th observation
= Since 100.5th observation lies in the row of cumulative freq. = 129
= 2
Therefore, median number of registered vehicles per California household
= 2 vehicles

John has two coupons to use at a clothing store. One is for $20 off and
the other is for 20% off. John wants to purchase a shirt with one of the
coupons and wants to pay the least amount that he can. Choose the
answer that BEST describes the situation.
A. The shirt will have the lowest price with the $20 off coupon
B. The shirt will have the lowest price with the 20% off coupon.
C. The shirt will cost the same with either coupon.
D. It depends on the cost of the shirt as to which coupon will help John pay the lowest
price
Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.
Step-by-step explanation:
You do not know how much a 20% discount is unless you know the price of the shirt. This can be more or less than $20, so you don’t know.
Hope this helps!
Answer:
D.
Step-by-step explanation:
For example if a shirt was $100 dollars, 100-20 = 80 and 100 x .8 = 80
But if the shirt cost $35, 35-20 = 15 while 35 times .8 = 28
This shows that the cost of the shirt is important in discovering which coupon is better.
