Answer:
Calculator cost = $34
Step-by-step explanation:
x + (x+140) = 208
2x + 140 = 208
x=34
8 jars because you subtract 0.56 from 6. Afterwards, you divide the difference which is 5.44, by 0.68 and get eight.
The circumference is the diameter times PI
The exact circumference would be 9PI cm
The approximate circumference would be 9 x 3.14 = 28.26 cm
4x-6= 22
Move -6 to the other side.
Sign changes from -6 to +6.
4x-6+6= 22+6
4x= 22+6
4x= 28
Divide by 4 for both sides
4x/4= 28/4
x= 7
Answer : x= 7
