You have to use the distributive property to find the answer. so you do 2 times x which is 2x, then you do 2 times 14 which is 28. You do 2x=28. then you put a line down the equal sign. then you start on the side of the variable. so you divide by 2 on both sides. so 28 divided by 2 equals 14.
Answer:
182 cm³
Step-by-step explanation:
Let x cm³ be the total volume of the glass.
1/2 x + 65 = 6/7 x
by multiplying both sides by 2, we have
x + 130 = 12/7 x
5/7 x = 130
x = 182
Answer:
x = -7
Step-by-step explanation:
52 + 3x = -5x + 45 - 49
8x = -56
x = -7
Answer:
5π, about 15.708 units
Step-by-step explanation:
A 3-4-5 triangle is a right triangle. When a circle circumscribes a right triangle, the hypotenuse is the diameter of the circle. The circumference of a circle is given by ...
C = πd
For a diameter of 5 units, the circumference is ...
C = π(5) = 5π = 15.708 . . . units

<em>Additional comment</em>
The (3, 4, 5) triple is one of the first Pythagorean triples you run across. It is the smallest integer triple, and the only primitive triple with values in an arithmetic sequence. You can show this is a Pythagorean triple by ...
3² + 4² = 9 +16 = 25 = 5²
That is, these numbers satisfy the Pythagorean theorem relation for sides of a right triangle.
ANSWER
EXPLANATION
The given triangle has a right angle.
The side opposite to the 45° angle is 7 units.
To find angle x, we use the tangent ratio.
Recall the mnemonics TOA, which means,
To find y, we use the sine ratio, which means
