Solve for x in IJK Algebra
Oksi-84 [34.3K]

Answer:

x = 60

Step-by-step explanation:

The sum of the angles in a triangle is 180

40 + x+20 + x = 180

Combine like terms

2x+60 =180

Subtract 60 from each side

2x+60-60 =180-60

2x =120

Divide by 2

2x/2 =120/2

x = 60

Fareed wants to add 1/4 +5/8 Add the fractions by using the giant one to create a common denominator
saul85 [17]

Hi!

This question is about math.

\frac{1}{4}+\frac{5}{8}

<u><em>Least Common Factor 4 or 8: 8</em></u>

<u><em>Factors of 4 : 1, 2, 4 (prime factorization) (2*2)</em></u>

<u><em>Factors of 8: 1, 2, 4, 8 (prime factorization) (2*2*2)</em></u>

<u><em>Least Common Factor of a,b is the smallest positive number that divisible by both a and b.</em></u>

<em>Multiply each factor the greatest number of times it occurs in either 4 or 8.</em>

<em>Then multiply by the numbers.</em>

2*2*2

=8

<em>Multiply each numerator by the same amount needed to multiply its corresponding denominator to turn it into the Least Common Factor of 8.</em>

<em>For 1/4 multiply the denominator and numerator by the 2.</em>

\frac{1}{4}=\frac{1*2}{4*2}=\frac{2}{8}

\frac{2}{8}+\frac{5}{8}

<em>Since the denominator are equal, combine the fractions.</em>

\frac{2+5}{8}

<em>Add the numbers 2+5=7</em>

=\frac{7}{8}

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.

The function f(x) = 15(2)^x represents the growth of a frog population every year in a remote swamp. Elizabeth wants to manipula
weeeeeb [17]
Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
\dfrac{f(x)}{2} = \dfrac{15\cdot 2^x}{2} \\  \\ &#10;\dfrac{f(x)}{2} = \dfrac{15}{2}\cdot 2^x

Written in plain text: f(x)=15/2*2^x
