Change the mixed leading number into an improper fraction...a b/c=(ac+b)/c

19/7-7/8  the least common multiple of the denominators is 56 so:

(19/7)(8/8)-(7/8)(7/7)

(152-49)/56

103/56  now we can change back into a mixed number...

(56+47)/56

1 47/56

Answer:

x = 15

Step-by-step explanation:

angles 2 and 4 are supplementary so they add up to 180

2x + 10 + 4x + 80 = 180

6x + 90 = 180

6x = 90

x = 15

➷ 2) The integral of a constant follows this rule:

adx = ax

In this case, it is 1dx = 1x

This can be simplified to just x

Add a constant to this, to get the final answer of:

x + C

3) The integrals power rule is:

x^adx = \frac{x^a^+^1}{a +1}

Substitute the values in:

\frac{x^5^+^1}{5 +1}

This can be simplified to:

\frac{x^{6} }{6}

Add a constant to this to get the final answer of:

\frac{x^{6} }{6} +C

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

4. ABCD below is a rectangle. BE=6x+2 and ED=4x+6. Find the length of AC.
Nikolay [14]

Answer:

28 units

Step-by-step explanation:

ABCD is a rectangle. AC and BD are diagonals intersecting at point E.

Diagonals of a rectangle bisect each other.

\therefore BE = ED

\therefore 6x + 2 = 4x + 6

\therefore 6x - 4x= 6-2

\therefore 2x= 4

\therefore x= \frac{4}{2}

\therefore x= 2

\therefore 6x + 2= 6*2+2= 12+2= 14

\therefore BE= 14\: units

\because BD = 2BE

\therefore BD = 2(14)= 28\: units

\because AC = BD (diagonals of a are equal in measure)

\therefore AC = 28\: units
