Derek is twice as old as Sarah. Two years ago the sum of their age was 20. How old is each now?
Answer:
Derek is currently 18 and Sarah is 8
Step-by-step explanation:
20=(x-2)
-2 because it was 2 years ago
20=(x-2) + (2x-2)
2x because Derek is twice as old as Sarah
20=(x-2) + (2x-2) can be changed to
20= 3x - 4 when you combine like terms.
24 = 3x you divide by 3 and you get 8=x
You plug in the number and you get the answer
20=(8-2) + (2*8 - 2) which can be transferred to
20= 6 + 14

b + 3/2b + b + 45 + 2b - 5 + 90 = 540
b + 1.5b + b + 45 + 2b - 5 + 90 = 540
5.5b + 130 = 540
5.5b = 540 - 130
5.5b = 410
b = 410/5.5
b = 74.5
Angles are
b = 74.5
1.5(74.5) = 111.75
74.5 + 45 = 119.5

5/5 Good job
Answer:
Hey
Step-by-step explanation:
Hey did you find the answers to this? i really need it. im desperate!
1. The market is said to be in disequilibrium because there is a shortage of apartments on the market
2. The equilibrium quantity of the good or service will decrease if demand decreases and supply decreases
3. The equilibrium price for this market is $20
4. It can be said that at a price level of $100 there is a a shortage of 0.4 million units
Equilibrium is the point at which quantity demanded equal quantity supplied
The price at this point is referred to as the equilibrium price.
Above equilibrium, there is a surplus - quantity supplied exceeds quantity demanded. As a result of the surplus, price would fall until equilibrium is reached.
Below equilibrium, there is a shortage - quantity demanded exceeds quantity supplied. As a result of the shortage, price would rise until equilibrium is reached.
A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases. A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, equilibrium quantity would decrease and there would be an indeterminate effect on equilibrium price
Equilibrium price is $20. This is because this is the price at which quantity demanded exceeds quantity supplied
There is a shortage because quantity supplied is less than quantity demanded
Shortage = 5.2 million - 4.8 million = 0.4 million

Consider the quadratic equation y^2 - y = 6. What is the error with the solution below?
y²-y=6
y(y-1)=6
y=6 or y-1=6
y=6 or y-1=6
y=6 or y=7
(6,7)
A. The solution is correct
B. In y²-y=6, y² should have been factored out instead of y.
C. In y²-y=6, y², 6 should have been subtracted on both sides first.
D. Instead of y=6, it should have been y=-6
Answer:
C. In y²-y=6, y², 6 should have been subtracted on both sides first.
Step-by-step explanation:
Hi there!
To solve the quadratic equation, one side must first equate to zero. This way, we could apply the zero product property.
Below is the correct solution:
y²-y=6
y²-y-6=0
⇒ Factor
(y-3)(y+2)=0
⇒ Apply the zero-product property
y= -2,3
