Answer:
t = 11/4
Step-by-step explanation:
Step 1: Write out equation
4t - 2 = 9
Step 2: Add 2 on both sides
4t = 11
Step 3: Divide both sides by 4
t = 11/4

Answer:
5
Step-by-step explanation:
Let the required number be x
![\huge {x}^{9} \div {x}^{6} = 125 \\ \\ \huge {x}^{9 - 6} = 125 \\ \\ \huge {x}^{3} = 125 \\ \\ \huge x = \sqrt[3]{125} \\ \\ \huge x = \sqrt[3]{ {5}^{3} } \\ \\ \huge \red{ x = 5}](https://tex.z-dn.net/?f=%20%5Chuge%20%7Bx%7D%5E%7B9%7D%20%20%5Cdiv%20%20%7Bx%7D%5E%7B6%7D%20%20%3D%20125%20%5C%5C%20%20%5C%5C%20%5Chuge%20%7Bx%7D%5E%7B9%20-%206%7D%20%20%3D%20125%20%5C%5C%20%20%5C%5C%20%5Chuge%20%7Bx%7D%5E%7B3%7D%20%20%3D%20125%20%5C%5C%20%20%5C%5C%20%5Chuge%20x%20%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20%5C%5C%20%20%5C%5C%20%5Chuge%20x%20%3D%20%20%5Csqrt%5B3%5D%7B%20%7B5%7D%5E%7B3%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20%5Chuge%20%5Cred%7B%20x%20%3D%205%7D)
Answer:
Step-by-step explanation:
(Tangent Length)^2 = y*(y + 11) You are going to have to use the quadratic formula on this.
Tangent Length = 7
7^2 = y * (y + 11)
49 = y^2 + 11y
0 = y^2 + 11y - 49
a = 1
b = 11
c = - 49
When you solve this quadratic equation you get
x1 = 3.40 which is the answer you go with.
x2 = -14.40 which can't be used. A negative length has no meaning.
