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
You put the number on top of 100 then multiply the other fraction
3 1/4 can turn into 13/4 as an improper fraction. 2 2/3 can turn into 8/3 as a improper fraction. To multiply fractions, just multiply the top by the top and the bottom by the bottom. This yields 104/12. Divide top and bottom by 4 yields 26/3 or 8 2/3
Answer:
C. 94
Step-by-step explanation:
Given that,
∠M = ∠T
(Opposite angles of the parallelogram)
- b - 10 = 86°
- b = 86 + 10
- b = 96°
Now, ∠H + ∠T = 180°.
(Adjacent angles of the same size)
- x + b - 10 = 180°
- x + 96 - 10 = 180°
- x + 86 = 180°
- x = 180 - 86
- x = 94°
Now, ∠H = ∠A
(Opposite angles)
21. if Sam's erasers are represented by x, then sari, who has three times more, would be represented by 3x. since you are adding two together to get 28, the equation would be 28=3x+x. Simplify to 28=4x, divide by 4 to isolate x, where x=7. multiply this by 3 to get sari's amount.
