1) X=159
2) BCD=103
3) DCH=89
im pretty sure
To simplify rational expressions, simply see and check if there is a common number or same number that can be divided from in both. If not here, you would simply multiply the numbers together.
Then simplify if you would need to.
It would be 85x/6
Answer:
Step-by-step explanation:
a + 143 = 180 {Linear pair}
a = 180 - 143
a = 37
37 + 93 + b = 180 {Angle sum property of triangle}
130 + b = 180
b = 180 - 130
b = 40
c + b = 90
c + 40 = 90
c = 90 - 40
c = 50
d + 120 = 180 {Linear pair}
d = 180 - 120
d = 60
? = 60 + 40 {Exterior angle property of triangle}
? = 100
The total price that Peter paid for the local parcel = $2.07
The rate per ounce at that time was = $0.23/ounce
Total weight of Peter's package = Total price paid by peter/ rate per ounce
Total weight of Peter's package = $2.07/$0.23 per ounce
We now have to divide 2.07/0.23 = 207/23 (Shifting both numerator and denominator by 2 decimal places) = 9
Total weight of Peter's package = 9 ounces
