Answer:
1 3/4 = 7/4 = 1.75
Step-by-step explanation:
The process to arrive to the solution is explained in the pictures below.
Tyler needed to convert the mixed fraction
2 1/2 = (4+1)/2 = 5/2
If we multiply by 2 numerator and denominator
5*2/2*2 = 10/4
We substract
10/4 - 3/4 = 7/4 = 1.75
Answer:
y= 14
Step-by-step explanation:
Given that AC= BC, △ABC is an isosceles triangle.
∠CBA= ∠CAB (base ∠s of isos. △)
∠CBA= 50°
∠ACB +50° +50°= 180° (∠ sum of △ABC)
∠ACB +100°= 180°
∠ACB= 180° -100°
∠ACB= 80°
Given that ∠ACB= (5y +10)°,
(5y +10)°= 80°
5y +10= 80
5y= 80 -10 <em>(</em><em>-10</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
5y= 70 <em>(</em><em>simplify</em><em>)</em>
y= 70 ÷5 <em>(</em><em>÷</em><em>5</em><em> </em><em>throughout</em><em>)</em>
y= 14
Answer: x=14
Step-by-step explanation:
Add 5 to both sides to get the x alone and get your answer.
we know that
in the right triangle JKL
Because
and are complementary angles
so
therefore
<u>the answer is</u>
The answer to the problem is 45.
