Answer: x =15.

Step-by-step explanation:

100 - 6x = 160 - 10x

-6x = 160 - 10x - 100

-6x = 60 - 10x

4x = 60

x = 15

Help me find weather or not these sides satisfy the triangle
schepotkina [342]

Answer:

No, the sides do not satisfy the triangle.

Step-by-step explanation:

OK, so you can use either use the Pythagorean Theorem or the 45-45-90 Triangle Theorem to find the answer to the question. I am going to use both in this explanation to help you see how they can be used.

Pythagorean Theorem:

a^{2}+b^{2}=c^{2}

45-45-90 Triangle Theorem:

a = b and c=a\sqrt{2} or b\sqrt{2}

Use Pythagorean Theorem:

So a=2\sqrt{3}, b=2\sqrt{3}, and c=6.

(2\sqrt{3})^{2}+(2\sqrt{3})^{2}=6^{2} ?

(4×3) + (4×3) = 36 ?

12 + 12 ≠ 36

24 ≠ 36

Sides do not satisfy the triangle.

Use 45-45-90 Triangle Theorem:

6=2\sqrt{3} \sqrt{2} ?

6=2\sqrt{6} ? no

Sides do not satisfy the triangle.

Which is the simplified form of the expression 3(7/5x+4) - 2(3/2 - 5/4x)?
Kruka [31]

Answer:

B. \frac{67}{10} x + 9

Step-by-step explanation:

Simplify the expression. Remember to go by the order of operations, or PEMDAS.

1) First, distribute the numbers outside of the set of parentheses to the terms inside the set of parentheses next to them. Then, simplify the fractions.

3(\frac{7}{5} x + 4) -2 (\frac{3}{2} -\frac{5}{4} x)

\frac{21}{5}x + 12  - \frac{6}{2} + \frac{10}{4} x

\frac{21}{5} x + 12 - 3 + \frac{10}{4} x

2) Finally, combine like terms. (This means to add or subtract constants and to add or subtract terms with the same variables.) You may need to convert terms to the same denominator in order to do so easier. Then, reduce the fraction.

\frac{21}{5} x + 9 + \frac{10}{4}x \\\frac{84}{20}x + \frac{50}{20}x + 9 \\\frac{134}{20}x + 9 \\\frac{67}{10}x + 9

Thus, the answer is \frac{67}{10} x + 9.
