Answer:
2/3
Explanation:
<u>total people</u>: 4 + 2 = 6 people
<u>carpenters</u>: 4 carpenters
<h3>probability = favourable outcomes/total possible outcomes</h3>
probability = 4/6 ≈ 2/3
subtract equations to form the equation of:
2x + 2y = 8
rearrange first equation to make x the subject:
x = 4 - 2y
subsitute into 2x + 2y = 8
2 (4 - 2y) + 2y = 8
8 - 4y + 2y = 8
collect like terns
-2y + 8 = 8
8s cancel out
-2y = 0
divide by -2
<u>y</u><u> </u><u>=</u><u> </u><u>0</u>
substitute y value into x + 2y = 4
x + 2 (0) = 4
solve for x
x + 0 = 4
<u>x</u><u> </u><u>=</u><u> </u><u>4</u>
therefore, the solutions are:
<h3>
<u>x</u><u> </u><u>=</u><u> </u><u>-</u><u>4</u></h3><h3>
<u>y</u><u> </u><u>=</u><u> </u><u>0</u></h3>
Y = -3/2x + 5/2
Explanation : You’d have to move the variables to the right and then simply divide both sides.

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any figure, so I'll assume m∠1 and m∠2 are complementary angles. Angles that add up to 90° are called complementary angles. In this case, we know m∠1 and want to know m∠2. Thus, we can establish the following formula:
m∠1 + m∠2 = 90°
Isolating m∠2:
m∠2 = 90° - m∠1
m∠2 = 90° - 64
m∠2 = 26°
Answer:
12.5
Step-by-step explanation:
(3+8)/2 = 5.5
5.5 + 7 = 12.5
