Answer: The equations are A= 600 + 125w and A = 1100 + 50w. Look into the steps for more information.
Step-by-step explanation:
Zypel's situation can be represented by the equation, A= 600 + 125w where A is the amount of money she will have after w weeks.
The same way we can represent Joshua's situation by the equation
A = 1100 + 50w where a is also the amount of money he will save after w weeks.
It says that there are 4 weeks in one month which means there will be 16 weeks in 4 months.
Now input 16 into the equations for w and solve for A.
A = 600 + 125(16)
A= 600 + 2000
A = 2600
So Zypel will save $2600 in a 4 months
A = 1100 + 50(16)
A= 1100 +800
A= 1900
So Zypel will save more than Joshua in four months.
20 % = 20/100 = 1/5
1 red marble out of 5 total marbles
1 red marble and 4 not red marbles
odds in favor means number of favorable outcomes : number of unfavorable outcomes
this basically means red marbles : not red marbles
1: 4
Answer:
B) One solution: x=1, y=4
Step-by-step explanation:
The number of points of intersection mark how many solutions there are. In this case, the two lines only intersect at one point, hence one solution. This point is located at (1, 4).
