Help! Clear the fractions
I am Lyosha [343]

Answer:

x = - \frac{27}{20}

Step-by-step explanation:

Given

\frac{5}{6} x + 2 = \frac{7}{8}

Multiply through by 24 ( the LCM of 6 and 8 ) to clear the fractions

20x + 48 = 21 ( subtract 48 from both sides )

20x = - 27 ( divide both sides by 20 )

x = - \frac{27}{20}

If one foot is the same length as 12 inches, how many inches equal 3.5 feet? (Only input whole numbers.)
lesantik [10]
1ft=12in
1ft/12in=1

3.5ft=?in
1ft:12in=3.5ft:?in
1ft/12in=3.5ft/?in
times both sides by 12?in
1?=42in

answer is 42 in

or you could just do
3.5 times 12=42 inches

Ivanshal [37]

Answer:

36

Step-by-step explanation:

Square roots have a neat property: \sqrt{ab}=\sqrt{a}\sqrt{b} provided <em>a</em> and <em>b</em> are positive real numbers.

This property is what's behind simplifying square roots.  You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.

Example: \sqrt{20}=\sqrt{4\times5}=\sqrt{4}\sqrt{5}=2\sqrt{5}.

In this problem, both factors are perfect squares.

\sqrt{9\times144}=\sqrt{9}\sqrt{144}=3\times12=36

Step-by-step explanation:

The area of a triangle is given by the formula

A = 1/2 bh where b is the length of the base and h is the height

b = 2 and h =2

A = 1/2 (2) * (2)

A = 1/2*4

A = 2 units^2
