Answer:
A=30
Step-by-step explanation:
We know through the Angle Sum Property of A Triangle that
all its angles add up to 180 degrees
Hence, A + (a+b) +B= 180
A+100+50=180
A+150=180
A=30
Answer: x=-2
Step-by-step explanation:
To solve for x, we want to isolate x.
-4(11x+2)=80 [distribute]
-44x-8=80 [add both sides by 8]
-44x=88 [divide both sides by -44]
x=-2
Now, we know that x=-2.
Let x be the number of days
Let y be miles travelled
Let z be total cost
a) 55x+0.45y=z
55x+0.45(300)=$2,335
b) 55x+135=$2,335
55x=2335-135
55x=2200
x=2200/55
x=40
c) She spent 40 days
