L = liz's age now
J = Jack's age now
L-1 and J-1 are their ages one year ago
L-1=3(J-1)
L-1=3J-3
L=3J-3+1
L=3J-2 (to be used later)
L+2 and J+2 are their ages in two years
L+2=2(J+2)
replace L by 3J-2
3J-2+2=2(J+2)
3J=2J+4
3J-2J=4
J=4 is Jack's age now
L-1=3(J-1)
L-1=3(4-1)
L-1=3*3
L-1=9
L=9+1
L=10 is Liz's age now

Answer is 63,000 pounds</h3>
The ratio 3:4 means for every 3 pounds made in away team tickets versus home team tickets. Multiply both sides by 9000 to have that 4 turn into 36000. The ratio 3:4 will then turn into 27000:36000
With this new ratio, we see that the away team pulls in 27000 and the home team pulls in 36000. Add the two amounts to get the final answer
27000+36000 = 63000
------------
We could alternatively add 3 and 4 (from the ratio 3:4) to get 3+4 = 7. Then multiply by that same scale factor 9000 getting 9000*7 = 63000.
Answer: 40 people
Step-by-step explanation:
There were 5 pies in the party and each person that came got an equal share of 1/8.
The number of people who were there is therefore:
= Number of pies / Share each person got
= 5 ÷ 1/8
= 5 * 8/1
= 40 people
Answer:
y = x+5 This equation satisfies all the four sets of x and y values 1.When x = 5,y = x+5 = 5+5 = 10 2.When x = 10,y = x+5 = 10+5 = 15 3.When x =15,y = x+5 = 15+5 = 20 4.When x = 20,y = x+5 = 20+5 = 25 Hence,
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
Line ED is a straight line. This means that it is 180. The other two angles combined are 130. Subtract 180 from 130 and you will get 50.
