Answer:
Explanation:
-4y - 3x = -11 (1)
x - 2y = 17 (2)
x = 17 + 2y
Substitute x value in (1)
-4y - 3(17 + 2y) = -11
-4y - 51 - 6y = -11
-10y - 51 = -11
-10y = -11 + 51
-10y = 40
y = 40/-10
y = -4
Substitute the y value in (2)
x - 2(-4) = 17
x + 8 = 17
x = 17 - 8
x = 9
Therefore, x = 9 and y = -4
Answer:
False
Step-by-step explanation:
Use the order of operations
45 * 89 = 4005
4005 + 67 = 4072
55 - 56 = -1
4072 < -1
The answer is false.

Step-by-step explanation:
<u>Finding x</u>
- Both the angles containing the x variable are on the same side of the transversal
- There is a property which states that : two angles on the same side of the transversal are supplementary
- Therefore, they add up to 180°
- ⇒ 8x + 12 + 2x + 18 = 180
- ⇒ 10x + 30 = 180
- ⇒ 10x = 150
- ⇒ <u>x = 15</u>
<u></u>
<u>Finding y</u>
- The angles at the top are vertically opposite angles (VOA), meaning that they are equal
- ⇒ 8x + 12 = 3y - 18
- ⇒ 3y = 8(15) + 12 + 18
- ⇒ 3y = 120 + 30
- ⇒ 3y = 150
- <u>⇒ y = 50</u>
4/5 divided by 8 is 0.1 other than that I don’t know that question is kind of vague
Answer:
A
Step-by-step explanation:
You convert each fraction to have the same decimal to find the LCD of both denominators
4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common
You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4
2 15/20 and 5 16/20
Subtract them and their is your answer
