To solve this, plug in the expression equal to x for x in the first equation.

2x - 3y = 2
x = 6y - 5

2(6y - 5) - 3y = 2
Use the distributive property.
2 • 6y = 12y
2 • -5 = -10

12y - 10 - 3y = 2
Combine like terms.
12y - 3y = 9y

9y - 10 = 2
Add 10 to both sides.
9y - 10 + 10 = 9y
2 + 10 = 12

9y = 12
Divide both sides by 9.
9y / 9 = y
12 / 9 = 1.3333...
y = about 1.33

x = 6y - 5
y = 1.33
Plug in the value of y in the expression equal to the value of x.

x = 6(1.33) - 5
Solve.
6 • 1.33 = 7.98
x = 7.98 - 5
7.98 - 5 = 2.98

Final answer:
x = 2.98
y = 1.33
As an ordered pair, this is (2.98, 1.33).

Hope this helps!

<h3>Look at the picture.</h3>

<em>commutative property</em>  a + b = b + a

... (-5 + 1/2 + 5) = ... (-5 + 5 + 1/2)

<em>inverse property of addition</em> a + (-a) = a - a = 0

... (-5 + 5 + 1/2) = ... (0 + 1/2)

<em>identity property of addition</em> a + 0 = 0 + a = a

... (0 + 1/2) = ... 1/2

<em>inverse property of multiplication</em> a/b · b/a = 1

37 · 2 · 1/2 = 37 · 2/1 · 1/2 = 37 · 1

<em>identity property of multiplication</em> a · 1 = 1 · a = a

37 · 1 = 37

What number line model represents the expression 2.5+4.5<br>Choose 1 answer: A, B, or C?<br><br>​
a_sh-v [17]

Answer:

A

Step-by-step explanation:

Because, the first point will be plotted at 2.5 (each line is 1 which means like line after 0 is 1, the next one is 2, and so one). When you add 2.5 with 4.5 it equals to 7 which means the next point will be placed at 7. (right behind 8)

I feel like i’m wrong lol, Correct me please.

The way you can figure out if a line is parallel, same line or perpendicular. Convert the systems of equation into slope intercept form. Here we have 3x+y=5. Subtract 3x. Y=-3x+5. Now let’s find the second system. 6x+2y=10. Now subtract 6x. 2y=-6x+10. Since we have 2y divide by 2 on both side. -6x/2=3. 10/2=5. Y=-3x+5. We can see the two Systems of equation gives us the same equation. Therefore the system has infinitely many solution or the same line.

Please answer this correctly
klemol [59]

Answer:

50%

Step-by-step explanation:

There are 6 sides on the die. 3 of the sides have even numbers (2,4,6) and 3 of the sides have odd numbers (1,3,5). Since there are the same amount of odd numbers as even numbers on the die, you have an equal chance rolling an even number as you do for an odd number. In other words, you have a 50% chance of rolling an odd number.

Hope this helps! :D
