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.

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:
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

I need to know how to show the work to get this answer
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

Help asap plz! Ron has a budget of $1,500 to paint the walls in his office building. One gallon of paint will cost 200 square feet and will cost $29.98, including tax. Paint can be bought in only 1 gallon cans. Additional painting supplies will cost $49 , including tax what is the maximum number of square feet Ron can paint if he stays within budget when he buys the paint and supplies?
The maximum number of square feet Ron can paint if he stays within budget when he buys the paint and supplies is 22.7.
Calculation of the maximum no of squaresSince the remaining would be
= $1,500 - $200
= $1,300
Now per unit cost should be like
= [tex]1,300 \div 29.98[/tex]
= 533
Now then the maximum no of squares should be
[tex]= 533 \div 49[/tex]
= 22.7
Hence, The maximum number of square feet Ron can paint if he stays within budget when he buys the paint and supplies is 22.7.
