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.
It is linear because it is constant
<span>1/2(7x-8)+2x =2-(10x+4)
Distribute
(7x-8)/2 + 2x = 2 -10x -4
combine like terms
(7x - 8)/2 + 2x = -10x - 2
Multiply both sides by 2
7x - 8 + 4x = -20x -4
Combine like terms
11x - 8 = -20x - 4
add 8 to both sides
11x = -20x + 4
add 20x to both sides
11x + 20x = 4
combine like terms
31x = 4
divide both sides by 31
x = 4/31 or </span><span>0.129.
