Evaluate 1/4r + 7/12 when r = 7/12

Mathematics
1 answer:
ExtremeBDS [4]3 years ago
7 0

Answer:

\frac{35}{48}

Step-by-step explanation:

Put the value of r in the equation.

\frac{1}{4} × r + \frac{7}{12}  = \frac{1}{4} × \frac{7}{12} + \frac{7}{12}

Evaluate.

\frac{1}{4} × \frac{7}{12} + \frac{7}{12} = \frac{7}{48} + \frac{7}{12}

Make them have the same denominator by multiplying the denominator of the second fraction by 4 so their denominators are 48.

\frac{7}{48} + \frac{7}{12} = \frac{7}{48} + \frac{28}{48}

Evaluate.

\frac{7}{48} + \frac{28}{48} = \frac{35}{48}

12/35 = 36/X find x step by step
Zigmanuir [339]

Answer:

x = 105°

Step-by-step explanation:

Question :

\frac{12}{35} =\frac{36}{x}

You can use cross multiplication to solve this.

Let us solve now

\frac{12}{35} =\frac{36}{x}

12 × x = 35 × 36

12x = 1260

Divide both sides by 12.

x = 105°

Hope this helps you :-)
