160 is the first because 1 inches 20 but it says 2 inches so at 40+40+40+40
and the 2nd part is yes he is correct because he converted the inches into feet so i think he is also correct
Simplify both sides 3x-6>-3
add 6 to both sides 3x-6+6>-3+6
divide by 3 3x/3>3/3
x>1
we know that
In the right triangle ABC
∠CAB=∠ABC=
so
we have
<u>using sines</u>
or
substitute the value of AB
or
<u>using cosines</u>
or
substitute the value of AB
or
therefore
<u>the answer is</u>
Answer:
x=10/3 or x=3 1/3
(Same thing)
Step-by-step explanation:
First, we distribute the 3 to 2x and 5:
6x+15=19+16
6x=20
x=20/6
x=10/3
x=3 1/3
