Answer:
t=0 and t=5
Step-by-step explanation:
5t = t^2
Subtract 5t from each side
5t-5t = t^2 -5t
0= t^2 -5t
Factor out a t
0= t(t-5)
Using the zero product property
t=0 and t-5 =0
t=0 and t-5+5=0+5
t=0 and t=5
Answer:
15x-2+7x+4=90°[being complementary angle]
22x+2=90°
22x=90°-2
22x=88
x=88/22
x=4
Answer:
The equation of the perpendicular line:
2x + 5y = ╼ 15
The amount saved by Rita is $25.
Given that, the skateboard Rita wants to buy is 6 dollars less than 3 times the amount she has saved. The skateboard is 69 dollars.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown number be x.
Now, 3x-6=69
⇒ 3x=75
⇒ x=75/3
⇒ x= 25
Therefore, the amount saved by Rita is $25.
