Answer:
y= -1
Step-by-step explanation:
(2) (0) − y = 1
0 + − y = 1
(−y) + (0) = 1
−y = 1
Step 2: Divide both sides by -1
Y = −1
Answer:
2x-7 or 7-2w
Step-by-step explanation:
Answer:
The answer is 7.
Step-by-step explanation:The tenths place is the first number after the decimal. In order to know what happens to the whole number you look at the number after the decimal and if its greater than 5 then goes up if no it stays the same. Ex: 2.5 rounded to the tenths place is 3
Answer:
<em>x = 49°</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
The sum of the internal angles in any triangle adds up to 180°.
The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.
The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:
43° + 39° + 2x = 180°
Operating:
82° + 2x = 180°
Subtracting 82°:
2x = 180° - 82° = 98°
x = 98°/2 = 49°
x = 49°
