Answer:
r - 5 = 2c
r = 75
Step-by-step explanation:
To write an equation for the problem, we first need do declare the value of the number of apps cora has.
Let c = Cora's apps
r - 5 = 2c
r - 5 is used to indicate that Rita deleted 5 apps.
2c is used to represent the twice the number of apps Cora has.
Now you said that Cora had 35 apps.
Let's plug that into the equation.
r - 5 = 2c
r - 5 = 2(35)
r - 5 = 70
Now we transpose the -5 to the other side to leave r.
r = 70 + 5
r = 75
So if Cora has 35 apps, then Rita will have 75 apps.
Answer:
Step-by-step explanation:
i=prt
i=?
p=4500
r=2.85=0.0285
t= 3 years
so=4500*0.0285*3
equals=384.75

ez points I guess pls pls pls pls
Answer: x=5π/4
Step-by-step explanation:
sin x = cos x
sin^2 x=cos^2 x
sin^2 x+sin^2 x=cos^2 x+sin^2x
2 sin^2 x=1
sin^2 x=1/2
sin x=(1/2)^1/2
sin x=
x=45 degrees, 225 degrees
x=180/4, 5(180)/4
x=π/4, 5π/4 ==> π<=x<=3π/2
x=5π/4
I wish I could help you out on that
