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.
may someone help me ASAP?! 24x^4+92x=11x
Answer:
x=0 or x= -3/2
Step-by-step explanation:
Step 1: Subtract 11x from both sides.
24x4+92x−11x=11x−11x
24x4+81x=0
Step 2: Factor left side of equation.
3x(2x+3)(4x2−6x+9)=0
Step 3: Set factors equal to 0.
3x=0 or 2x+3=0 or 4x2−6x+9=0
x=0 or x= -3/2
2b-(3-b) + 4 = 11
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

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

Answer:
36 ft
Step-by-step explanation:
The ratio of the lengths of the sides is the same as the ratio of the perimeters.
Just like one side (15 ft) of triangle ABC is 3 times as long as the corresponding side (5 ft) of triangle DEF, the perimeter of triangle ABC is also 3 times the perimeter of triangle DEF.
15/5 = x/12
3 = x/12
x = 36
Answer: 36 ft

Pranza plotted point A in the coordinate plane below.
On a coordinate plane, point A is 0.75 units to the right and 0.5 units down.
She says that the plotted point is (One-fourth, negative one-half). What is Pranza’s error?
A.) The x- and y-coordinates are switched.
B.) Both coordinates should be positive.
C.) The x-coordinate should be Three-fourths.
D.) The y-coordinate should be One-half.
Answer:
C. The x-coordinate should be Three-fourths.
Step-by-step explanation:
Since point A is 0.75 units to the right, it is 3/4 if 4/4 is 100.
Answer:
C. The x-coordinate should be Three-fourths.

help me pls i don't know
Answer: so the a is 4 and the b is 3
that means you have to write 6+1+1 and that equals 8.
your answer is 8
Step-by-step explanation: in order to get that you have to replace a with 4 and b with 3, if you do you will see that they are simplified to 1. so if you add that the answer is 8. i hope this helped.
