Answer:
number one is 90°
Step-by-step explanation:
number 9 is an acute angle
A) 3 dollars
b) P = 0.5x - 475
c)950
d)-200
Answer:
18
Step-by-step explanation:
27/150*100/1
divide by 3
9/50*100
100/50=2
9*2=18
For part A: the constant is 83.50. the variable would be c and w. and the coefficient would be 10c or 15w.
part B: so 10(4)+15(15)+83.50 -----> 10x4= 40------> 40+15(15)+83.50---->15x15=225
40+225+83.50=348.50
part C The coefficient would change because a constant is always constant, a variable is just a letter standing in for a number which would make the coefficient the one that changes for $10 to $20.
hope that help!
