Answer:
x-7
Step-by-step explanation:
Answer:
x = 41
Step-by-step explanation:
We know these angles will be equal to each other (they are across from each other, I honestly forget the term ) so we can set up an equation
Our equation from given: 104 = 3x - 19
Adding 19 to both sides 123 = 3x
Dividing both sides by 3: 41 = x
Answer: x = 41
Answer:
Step-by-step explanation:
Two Decimal places
.9(29.3) = 26.37
18(5.75)= 103.50
Three Decimal places
3.21(2.4) = 7.704
50.7(14.06)= 712.842
Four Decimal places
4.2(.938)= 3.9396
.48(12.19)= 5.8512
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
