Answer:angle 1=90 angle 2=45 angle 3=45
Step-by-step explanation:
Answer:
x=67 y=113 x=52
Step-by-step explanation:
85+28= 113
180-113=67
67= x
67+28=95
95+85=180
y= 28+ 85 =113
113+15= 128
180-128=52
52=x
A. Write a system of equations to describe the situation
Answer:
25.66 miles
Step-by-step explanation:
fee of $2.90 plus --> $2.90 + _______ = ______
total fare was $44.90--> ______ +______ = $44.90
$1.75 per mile,per mile would be <u>x </u>since the number of miles are unknown
$1.75 per mile --> ______ + $1.75x = ______
<em>Put together:</em> $2.90 + $1.75x = $44.90
<u>Note:</u> It could be written as '$1.75x + $2.90 = $44.90', it really doesn't matter
1. Subtract $2.90 from both sides : <u>$1.75x + $2.90 - $2.90 = $44.90-$2.90 </u>resulting in <u>$1.75x = $44.90</u>
2. Divide $1.75x form both sides: <u>$1.75/$1.75x = $44.90/$1.75</u><u> </u>resulting in <u>x=25.66</u>*rounded from 25.6571428571
<em><u>x=25.66 miles</u></em>
Note: If you are subtracting,adding, or etc. on one side, you HAVE to do it on the other side too.
Answer:2x-5
Step-by-step explanation:-(x+5)+3x
-x-5+3x=(3x-x) -5
=2x-5
