Answer:
<h2><u><em>
y = 70°</em></u></h2>
Step-by-step explanation:
x = 35° (opposite agles)
y = 180 - 35 - 75
y = 70
-----------------------
check 35 + 75 + 70 = 180°
the answer is good
Answer:
10
Step-by-step explanation:
Well to find the missing side you're going to need the other two. Take the one side and multiply by itself. Take the other one and multiply by itself. Add those two products. Then root it. Basically find something that multiplys by itself to get that product
X = pencils, y = pens
8x + 6y = 8.50
4x + 4y = 5.....multiply by -2
----------------
8x + 6y = 8.50
-8x - 8y = -10 (result of multiplying by -2)
-----------------add
-2y = - 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75
4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50
You will end up with 8 bc if you cut it in half it is dividing so you would do 4×2 and the answer is 8
