Answer:
-7
Step-by-step explanation:
Given the expression
4y - 2(1 - y) = -44
First expand the bracket
4y - 2 x 1 -2 x -y = -44
Negative times negative gives positive
4y - 2 + 2y = -44
Rearrange the expression
4y + 2y - 2 = -44
6y - 2 = -44
Add 2 to both sides
6y - 2 + 2 = -44 + 2
6y = -42
Divide both sides by 6
6y/6 = -42/6
y = -7
Disagree because 24 divided by 1/2=48
Working out
24 divided by 1/2
To divide by a fraction, multiply by the reciprocal of that fraction
24 x 2
Multiply
48
Solution
48
When x = 1
5(1) = -y + 6
5 = -y + 6
y = 6 - 5 = 1
When x = 2
5(2) = -y + 6
10 = -y + 6
y = 6 - 10 = -4
When x = 3
5(3) = -y + 6
15 = -y + 6
y = 6 - 15 = -9
Collect like terms
15 + 3 + 9x + 7x = y
18 + 16x = y
Recall
b + mx = y
m = 16
b = 18

Answer: 90 degrees</h3>
=============================================================
Explanation:
This figure is a kite since we have two pairs of adjacent sides that are congruent, but not all sides are the same length.
One property of kites is that the diagonals are always perpendicular (this applies to rhombuses as well). This means angle 3 is 90 degrees.
