Answer:
X = 80
Step-by-step explanation:
Subtract "5" from both sides,
3x + 5 - 5 = 245 - 5
Simplify,
3x = 240
Divide both sides by "3",
3x/3 = 240/3
X = 80

Answer:
Step-by-step explanation:
Let the family's expense be x
In the Chang family's budget, 0.6% of the expenses are for internet service.
Then expense for internet service=0.6 % of x
The fraction of family's expense is for internet service =
Hence the fraction of family's expense is for internet expense=
Answer:
The answer provided is incorrect, the mistake is in the division between the monomials and that is equal to not , because we must mantain the same base "x" and subtract the expoents that are .
Step-by-step explanation:
In order to simplify that question we need to multiply, divide and power monomials with the same base "x". When we multiply monomias with the same base we sum the expoents, to divide we subtract the expoents and to power them we multiply the expoents. Therefore to simplify the equations we must do:

Answer:
No the answer is incorrect.
Step-by-step explanation:
From the question given;
( . / )¹/²
We will start by solving the inner bracket
By the law of indices
. =
we will replace . by
. by
( . / )¹/² = ( / )¹/²
By the law of indices
/ = =
We will replace / by
( / )¹/² = ( )¹/² = =
( . / )¹/² =
No the answer is incorrect.
He made a mistake, because / = = = and not equal to
Answer:
x = 48, x - 6 = 42, 2x = 96
Step-by-step explanation:
To solve this problem, we must first notice that the unlabeled angle must also have a measure of (x-6). This is because two of the legs of the triangle are congruent, so the adjacent angle measures must be the same.
From this, we can recall that the sum of the interior angles of a triangle must equal 180 degrees. This fact lets us set up the following equation:
(x-6) + (x-6) + 2x = 180
After simplifying, we get:
(x + x + 2x) + (-6 - 6) = 180
4x - 12 = 180
4x = 192
x = 48
Therefore, the value of x is 48. We can plug in this value to find the angle measures:
x - 6 = 48 - 6 = 42
2x = 2(48) = 96

Answer:
x = 48°, Isoceles angles = 42° and Remaining angle = 96°
Step-by-step explanation:
The sum of the interior angles of any triangle is 180 degrees. This is true for all triangles, regardless of their shape or size.
Isosceles triangles have two equal sides and two equal angles opposite those sides. This means that the two base angles of an isosceles triangle are congruent.
Inthis case:
The given triangle is isoceles triangle. So, the remaining angle is (x-6)°.
Since sum of the interior angles of any triangle is 180 degrees.
we can say that:
(x-6)° +(x-6)° + 2x° = 180°
Simplify like terms:
4x° - 12 = 180°
Add 12 on both sides.
4x - 12 + 12 = 180 + 12
4x = 192
Divideboth sides by 4.
x = 48°
The other angles are:
