Answer:
-13 =x
Step-by-step explanation:
−57 = 5x + 8
Subtract 8 from each side
-57 -8 = 5x +8-8
-65 = 5x
Divide by 5 on both sides
-65/5 = 5x/5
-13 =x
X=3 is a relation because there is no context for it to be a function. x is a variable, and there is no equation to support it. Therefore, it has to be 3.
Answer:
1001 in base 2.
Step-by-step explanation:
1010001
= 1 + 2^4 + 2^6
= 1 + 16 + 64
= 17 + 64
= 81 in base ten.
Square root of this is 9
In base 2 this is 1001
Answer:
x = 21
Step-by-step explanation:
Given that SV is the angle bisector of ∠RST, then
∠RSV = ∠TSV, thus
∠RSV + ∠TSV = ∠RST ← substitute values
2x + 8 + 2x + 8 = 6x - 26, that is
4x + 16 = 6x - 26 ( subtract 6x from both sides )
- 2x + 16 = - 26 ( subtract 16 from both sides )
- 2x = - 42 ( divide both sides by - 2 )
x = 21
