108 is the correct answer
Lets x = Mary's age
Emily is there years older than twice her sister Mary's age = 2x + 3
Sum of both is less than 30:
x + 2x + 3 < 30
Solve for x
3x + 3 < 30
3x < 27
x < 9
Mary's age = 9
Inequality represents Mary's possible age:
0 < x < 9
Answer is the second one
0 < x < 9
The length is 9 feet.
The formula for Area is A= L*W*H.
You are given A=189, W= 7 feet and H= 3 feet. Solve formula for
L.
189= L*7* 3
189=21 L
Divide both sides by 21 to solve for L
189/21 = 21L/21
9=L
7/10 in its simplest form is 0.7
Answer:
3.20
Step-by-step explanation:
Intercept form of a line : Y = mx + b
m = y2 - y2 / x2 - x1 ....use this to find the slope whenever 2 points are given.
In this case it's directly given.
