Part (a)
Answer: x = -8------------------
Work Shown:
2(x-1) = 3(x+2)
2x-2 = 3x+6 .... distribute
2x = 3x+6+2 .... adding 2 to both sides
2x = 3x+8
2x-3x = 8 .... subtracting 3x from both sides
-x = 8
x = -8 ..... multiply both sides by -1
===========================================================
Part (b)
Answer: x = 5/11------------------
Work Shown:
-4(2x-2) = 3(x+1)
-8x+8 = 3x+3 ..... distribute
-8x = 3x+3-8 .... subtract 8 from both sides
-8x = 3x-5
-8x-3x = -5 ... subtract 3x from both sides
-11x = -5
x = -5/(-11) .... divide both sides by -11
x = 5/11
In decimal form, this is approximately equal to 5/11 = 0.4545
sb pls answer this lollllllll!?
Answer:
y = 1.5x
Step-by-step explanation:
We are to find the equation of the line
The equation is expressed as y = MX+c
m is the slope
c is the intercept
Get the slope
Using the coordnate (10, 15) and (20, 30)
m = 30-15/20-10
m = 15/10
m = 1.5
Get the intercept
Substitute m = 1.5 and (10, 15) into y = mx+c
15 = 1.5(10) + c
15 = 15+c
c = 0
Get the equation
y = mx+c
y = 1.5x+0
y = 1.5x
Hence the required equation is y = 1.5x
Answer:
y=1.5x

Kanye and his two friends are sharing the cost of lunch. the total cost of the bill is $15.27 . if Kanye has $20, how much will he have left after he pays his share?
Answer:$4.73
Step-by-step explanation:
Answer:
If Kayne is with his two friends, that means there are three people in total.
If there are three people sharing the price of this lunch, each person would have to pay 15.27/3 dollars.
Dividing, we get that each person must pay 5.09 dollars.
Subtracting 5.09 from 20, we have that Kayne will have $14.91 left after paying his share.
Hope this helps!

The graph of an exponential function passes through (1, 10) and (4, 80). Find the function that describes the graph.
Answer:
y = 5*2ˣStep-by-step explanation:
Exponential function:
y = abˣOrdered pairs given:
(1, 10) and (4, 80)Substitute x and y values to get below system:
10 = ab80 = ab⁴Divide the second equation by the first one and solve for b:
80/10 = b³b³ = 8b = ∛8b = 2Use the first equation and find the value of a:
10 = a*2a = 5The function is:
y = 5*2ˣAnswer:
[tex]y=5 \cdot 2^x[/tex]
Step-by-step explanation:
An exponential function is written in the form:
[tex]y=ab^x[/tex]We can use the given points that the exponential function passes through to solve for a and b.
Create a system of equations by substituting (1, 10) and (4, 80) into the exponential form of a function.
[tex]\text{I}:\ 10=ab^1[/tex] [tex]\text{II}: \ 8 0=ab^4[/tex]Divide Equation I by Equation II in order to cancel out variable a.
[tex]\displaystyle \frac{80=ab^4}{10=ab}[/tex][tex]8=b^3[/tex][tex]b=2[/tex]Now we can solve for a by substituting b back into either equation from the system of equations.
[tex]10=ab[/tex] [tex]10=a(2)[/tex] [tex]a=5[/tex]Substitute 5 for a and 2 for b into the form of an exponential function to find the exponential function that passes through (1, 10) and (4, 80).
[tex]y=5 \cdot 2^x[/tex]y = 5 · 2ˣ is the exponential function that describes the graph.

3/4 + 3/5 how do you solve it
Answer:
3/4 + 3/5 = 1 7/20
Step-by-step explanation:
5 x 4 = 20
3/4 = 15/20
3/5 = 12/20
15/20 + 12/20 = 27/20 = 1 7/20
Answer: 1 7/20 (one and seven-twentieths)
Step-by-step explanation:
1) 3/4 = 15/20 and 3/5 = 12/20
2) 15/20 + 12/20 = 27/20
3) 27/20 = 1 7/20
Good Luck!

A college has a total of 107 teachers 23 more female teachers than male teachers
What proportion of the teachers are female? use n as the unknown
Answer:
Female reachers = 65
Step-by-step explanation:
Given that,
Total teachers in a college = 107
Let there are n male teachers.
Female reachers = n+23
ATQ,
n+n+23 = 107
2n = 107-23
2n = 84
n = 42
Female reachers = 42+23
= 65
Hence, there are 65 female teachers.

1. You want to put new carpet in your bedroom and the dimensions of your room
are 8.74 ft and 10.3 ft. If you want to find the area of your room to put new carpet
in, which of these problems would help you estimate how much carpet will you
need to buy?
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that a new carpet is to be put in the bedroom and that the dimensions of the room are 8.74 ft and 10.3 ft.
The area of the room will be the multiplication of the dimensions given. This will be:
= 8.74 × 10.3
= 90.022
= 90ft²
