35-7 which would equal 28, but that answer wouldn't be exactly correct, as this isn't in correct formation. An equation would be 2x + 7 = 35.
35-7= 28 divided by 2(2x) would equal 14
So Mary is 14 and her sister is 21.
21 + 14 equals 35
Answer:
60
Step-by-step explanation:
28+24+8
Answer: 16
Step-by-step explanation:
First, you need to do 12+16, which gives you 28. Next, you need to do 92-28, which gives you 64, then divide that by 4 and you get 16.
Answer: 17.5 square yards
================================================
Work Shown:
base = 5 yards
height = 7 yards
The base and height are always perpendicular to one another
area of triangle = 0.5*(base)*(height)
area of triangle = 0.5*(5)*(7)
area of triangle = 17.5 square yards
The other values aren't used. They're likely thrown in as a distraction.
The point would be (-2,1). x = -2, y = 1. I hope this helps, have a good day!
