Find x if AB = 9, BC = 2x - 5,<br> and AC = x + 9

Oxana [17]

Answer:

x = 5

Step-by-step explanation:

Using the fact that line segments AB and BC are parts of the whole line segment AC, we can write the following equation:

AB + BC = AC

Now, using the given values, we can substitute in for the equation and solve for x:

AB + BC = AC

9 + 2x - 5 = x + 9

2x + 4 = x + 9

x = 5

Thus, we have found that for these sets of equations for these line segments, our value for x should be 5.

Cheers.

A)4*16

because 4*3•4*4•4*9
you have to add the exponents

3+4+9=16
keep the number

so 4*16 is the answer

Solve the equation. \dfrac18 + c = \dfrac45 8 1 +c= 5 4 start fraction, 1, divided by, 8, end fraction, plus, c, equals, sta

aivan3 [116]

Answer:

$c=\dfrac{27}{40}\\$

Step-by-step explanation:

We are required to solve for c in the equation: $\dfrac{1}{8}+c= \dfrac{4}{5}$

Step 1: Collect like terms

$\dfrac{1}{8}+c= \dfrac{4}{5}\\c= \dfrac{4}{5}-\dfrac{1}{8}$

Step 2: Find the Lowest Common Multiple of the denominators

LCM of 8 and 5 is 40

Step 3: Multiply all through by 40

$40c= \dfrac{4}{5}*40-\dfrac{1}{8}*40$

Step 4: Simplify

40c=32-5

40c=27

Step 5: Divide both sides by 40 and simplify if possible.

$c=\dfrac{27}{40}\\$

Of the 1450 books in the library, there are 6 times as many books in the fiction section as are in the nonfiction section. Also,

guajiro [1.7K]

Number of books in non fiction section = 200

Number of books in fiction section = 800

Number of books in reference section = 850

Step-by-step explanation:

Total number of books in the library = 1850

Let us assume, number of books in non fiction section = m

Number of books in fiction section= 4 x Number of books in non fiction

= 4 x (m)

So, the number of books in reference section = 650 + m

Now, Total Number of books = Number of { Fiction + Non- Fiction + Reference} Books

or, 1850 = m + (4 m) + 650 + m

or, 6 m + 650 = 1850

⇒ 6 m = 1850 - 650 = 1200

or, m = 1200 / 6 = 200

⇒ m = 200

Hence, the number of books in non fiction section = 200

Number of books in fiction section = 4 m = 4 x 200 = 800

Number of books in reference section = 650 + m = 200 + 650 = 850
