Answer:
A) x=23
B) angle 1 = 73, angles 4, 5, and 8 are congruent
C) angle 2 = 107, angles 3, 7, and 6 are congruent
Step-by-step explanation:
Let n = the unknown number.
Quotient tells you use division.
n/7 = 39
Multiply both sides by 7 to cancel out the number in the denominator and isolate the variable.
n = 39(7) = 273
n = 273
Can't really show my work, but it's 15 students who like PE.
Just divide A by B, then using that number, move the decimal 2 spaces to the right.
Answer:
The variable "a number" stands for 9.
Step-by-step explanation:
Rewrite the problem as 2 * (6 + x) = 30
Divide 30 into 2. 30/2 = 15
That means that the variable that is added to 6 must make the number 15.
15 - 6 = 9
The variable x is 9 so the equation would be:
2 * (6 + 9) = 30
