Answer:
Jane: 37 years old
Anne: 17
Step-by-step explanation:
Jane 12 years ago: 5x
Anne 12 years ago: x
In three years into the future:
Jane: 5x+15
Anne: x+15
CURRENT TIME:
Jane: 5x+12
Anne: x+12
Equation (using 3 years into the future ages): 5x+15=2(x+15)
5x+15=2x+30
(subtract 15 from both sides)
5x=2x+15
3x=15
x=5
Therefore, Jane is 37 years old and Anne is 17 years old.
Step-by-step explanation:
180 -angled triangle,
180-56 = 124
124/2 = 62 (each corner of the right triangle)
then find the corner below
the rectangle has right angles on the right side
x = 90-62
= 28
1. Change 1 7/8 to an improper fraction, which gives you 15/8.
2. Use KFC to divide fractions. KEEP the first term, FLIP the second and CHANGE to multiplication.
3. 15/8 x 4/3 = 60/24 = 2 1/2
