Graphing the Solution of an Inequality on the Number Line
Graph the solution of this inequality:
3/4 (x+8) > 1/2 (2x +10)
Answer:
x < 4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
Step 2: Subtract x from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Multiply both sides by 4/(-1).

Blank 1 = 3Blank 2 = 3In other words, x = 3 and y = 3
===========================================================
Explanation:
Let's solve the first equation for x. I'm picking on this equation variable because the coefficient is 1.
Solving for x leads to
x-2y = -3
x = -3+2y
I added 2y to both sides
Now we'll plug this into the other equation. This means we replace every copy of x with -3+2y since they are the same thing.
3x + 5y = 24
3( x ) + 5y = 24
3( -3+2y ) + 5y = 24 .... replace x with -3+2y
3(-3) + 3(2y) + 5y = 24 .... distribute
-9 + 6y + 5y = 24
11y-9 = 24
11y-9+9 = 24+9 ...... adding 9 to both sides
11y = 33
11y/11 = 33/11 .... dividing both sides by 11
y = 3
We'll use this y value to find x. We can pick on any equation with x & y in it, but I find it's easiest to use the equation where x is isolated
x = -3+2y
x = -3+2(3) .... replace y with 3
x = -3+6
x = 3
So both x and y are equal to 3
-------------------------------
Let's check the answer
Plug (x,y) = (3,3) into the first equation. We should get the same number on both sides after simplifying fully
x-2y = -3
3 - 2(3) = -3
3 - 6 = -3
-3 = -3
So far, so good. Let's try the other equation
3x + 5y = 24
3(3) + 5(3) = 24
9 + 15 = 24
24 = 24
The other equation is true as well. This fully confirms that (x,y) = (3,3) is the solution to this system of equations. If you graphed each original equation, you should find they cross at the location (3,3).
Side note: it won't always be the case that x and y are the same value.

Round 1.0835 to the nearest hundredth
Answer:
1.1
Step-by-step explanation:
The decimal number 1.0835 rounded to nearest hundredth is 1.08.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, 1.0835 to round it to the nearest hundredth we'll look to the digit at thousands place which is less than 5 so we can make all the digits zero after the hundredth digit which is 1.0800 Or 1.08.

please help me asap !!!!!!!!
Answer:
−2(4x+3)=5+3x
Step 1: Simplify both sides of the equation.
−2(4x+3)=5+3x
(−2)(4x)+(−2)(3)=5+3x(Distribute)
−8x+−6=5+3x
−8x−6=3x+5
Step 2: Subtract 3x from both sides.
−8x−6−3x=3x+5−3x
−11x−6=5
Step 3: Add 6 to both sides.
−11x−6+6=5+6
−11x=11

Answer:
1.35 is the cost of the regular ice cream
Step-by-step explanation:
Consider the sequence shown.
436, 218, 109, 54.5, 27.25,...
Select the correct explicit formula for the sequence.
a
g_n=0.5·436^{(n-1)}
b
g_n=436·2^{(n-1)}
c
g_n=436·0.5^{(n-1)}
d
g_n=2·436^{(n-1)}
Given:
The sequence is
436, 218, 109, 54.5, 27.25,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
436, 218, 109, 54.5, 27.25,...
It is a GP because the two consecutive terms have common ratio.
Here,
First term : a=436
Common ratio : d = [tex]\dfrac{218}{436}[/tex]
= [tex]\dfrac{1}{2}[/tex]
= [tex]0.5[/tex]
Now, the explicit formula for a GP is
[tex]g_n=ar^{(n-1)}[/tex]
Where, a is the first term and r is the common ratio.
Putting a=436 and r=0.5, we get
[tex]g_n=436(0.5)^{(n-1)}[/tex]
Therefore, the correct option is c.

Answer:
1st scenario: 163.3°
2nd scenario: 125.2°
3rd scenario: 142.3°
Step-by-step explanation:
1st scenario: angles 1 and 2 form a linear pair and add up to 180
2nd scenario: angles 1 and 4 are same-side interior and add up to 180
3rd scenario: angles 1 and 8 are corresponding and equal; if angle 7 is 37.7 then angle 8 is 142.3 (they form a linear pair). Since angles 1 and 8 are equal then angle 1 is also 142.3
Every week, Fred deposits $84 into his savings account, which is 20% of his weekly income. How much income does Fred make each week?
Answer:
Fred's monthly income is $420.
Step-by-step explanation:
There are two main ways of solving this. There are many ways of solving for this, but personally I like to do divide the percentage by 100 so it would look something like this-
100/20 = 5.
Then I multiply $84 by 5 which is $420.
Answer:
ze answer is 420 since 84 is 20% of 100 and 20 x 5 - 100 so,84 x 5 = 420

Answer:
10/3
Step-by-step explanation:
Simplifying 2b - (3-b) gives us:
2b - (3 - b) =
2b - 3 + b =
3b - 3
This makes our new equation:
3b - 3 + 4 = 11
Combine like terms
3b + 1 = 11
Subtract 1 from both sides
3b = 10
Divide both sides by 3
b = 10/3
