Answer:
x +
x = 2x - 25
Step-by-step explanation:
First, let's analyze the phrase "the sum of one-half and two-thirds the number". This would translate to:
x +
x
Then it says the last part of the expression is "twenty five less than twice the number"
2x - 25
Then, equal the two parts of the equation to each other.
x +
x = 2x - 25
Hope this helps! :)
Answer:
t = 13
Step-by-step explanation:
By the definition of an isosceles triangle,
Two sides of the isosceles triangle ABC will be equal in measure.
Therefore, AC = BC
Equation for the value of 't' will be,
(2t + 5) = (3t - 8)
3t - 2t = 5 + 8
t = 13
Therefore, t = 13 will be the answer.
