Solve for X. 3/4x+7/8=4 1/4 Enter your answer as a mixed number in simplest form in the box.
neonofarm [45]

Step-by-step explanation:

\frac{3}{4} x +  \frac{7}{8}  = 4 \frac{1}{4}

\frac{3}{4} x =  \frac{17}{4}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{34}{8}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{27}{8}

3x \times 8 = 27 \times 4

24x = 108

x =  \frac{108}{24}

x =  \frac{9}{2}

Find
Zarrin [17]

The measures of two complementary angles are 64 degrees and 26 degrees

<h3><u>Solution:</u></h3>

Let the larger angle be "a" and smaller angle be "b"

<em>Two angles are Complementary when they add up to 90 degrees</em>

so we get,

a + b = 90 ------ eqn 1

Given that measure of the larger angle is 12 more than twice the measure of the smaller angle

larger angle = 12 + 2(smaller angle)

a = 12 + 2b --- eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to get values of "a" and "b"</u></em>

Substitute eqn 2 in eqn 1

12 + 2b + b = 90

12 + 3b = 90

3b = 90 - 12

3b = 78

<h3>b = 26</h3>

Therefore from eqn 2,

a = 12 + 2b

a = 12 + 2(26)

a = 12 + 52

<h3>a = 64</h3>

Thus the measures of two complementary angles are 64 degrees and 26 degrees
