5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
Answer:
yup this explanation is correct you will get good grade
diameter is radius x 2
3.5 x 2 = 7 inches
Area = PI x r^2
using 3.14 for PI
area = 3.14 x 3.5^2 = 3.14 x 12.25 = 38.465 square inches round answer as needed

Answer:
The father is 59
Step-by-step explanation:
lets say each of the kids are twelve
30*5=150-36=114=59+55
30*5+ 150 the age of everyone in the family added together
12*3= 36 the age of all the kids
150-36=114 the age of the adults added together
we know the mother is 4 years younger than the father so to state off you can take 114 and divide it by two to get what half of it is then take take numbers that are four apart to find the ages that add up to 114.
