Answer:
x= c - b / A
please look at the step by step explanation to better understand :)
Step-by-step explanation:
subtract b from the left side and right side
so you are left with Ax = c - b
divide what number c - b is by A
and you are left with x= c - b / A
The total angles of a triangle must add up to 180 degrees, so y = 64 degrees
Answer:
The numbers are: 1 and 3.
Step-by-step explanation:
Let the first number be and the second number be .
Given: The difference between twice the number and the second number is . writing this mathematically,
From the second statement we get:
Solving for and we get:
and
Thus the first number is 1 and the second number is 3.
Answer:
a = 7, b = 9 and c = 4.
Step-by-step explanation:
7 ^ (9/4)
= (7^9) ^ 1/4
= ⁴√(7^9)
so a = 7, b = 9 and c = 4.
