The answer is 7 3/4.
Turn into improper fraction
= 77/8 − 15/8

= ((77 × 8) − (15 × 8)) / (8 × 8)

= (616 - 120) / 64

= 496/64

= 31/4

First, I would convert it an improper fraction. 9 5/8 = 77/8 1 7/8 = 15/8 77 - 15 = 62. The denominator stays the same. 62/8. Divide to make it a mixed number. 62/8 = 7 6/8 Simplified to = 7 3/4

Use the following image to assist in your answer. a = - 6 - 9 - 4

Step-by-step explanation:

Pythagoras' theorem for the smallest one :

$c^2 = 4^2 + 6^2$

$c^2 = 16 + 36$

$c^{2}$ = 52

Pythagoras' theorem for the middle one :

$b^{2}$ = $6^{2}$ + $a^{2}$

Pythagoras' theorem for the biggest one :

$(4+a)^2 = c^2 + b^2$

$16 + 8a + a^2 = 52 + b^2$

Using the formula before (for $b^2$ ) it becomes :

$16 + 8a + a^2 = 52 + (6^2 + a^2)$

$16 + 8a + a^2 = 52 + 6^2 + a^2$

$16 + 8a = 52 + 6^2$

16 + 8a = 52 + 36

16+8a = 88

8a = 88-16

8a = 72

$a = \frac{72}{8}$

a = 9

Verifying :

$b^2 = 6^2 + a^2$

$b^2 = 36 + 81$

$b^2 = 117$

$b^{2}$ = 117

The biggest one :

$(4+a)^2 = c^2 + b^2$

$(4+9)^2 = 52 + 117$

$13^2 = 169$

Find the lcd of the pair of expressions

STALIN [3.7K]

$\frac{2}{7} {x}^{10} {y}^{4} \: and \: \frac{2}{14} {x}^{8} {y}^{7} \\ lcd = 14 {x}^{10} {y}^{7}$
Answer is
$14 {x}^{10} {y}^{7}$

When it's powered numbers, remember to choose the one with the largest power. For example,
${x}^{10}$
And
${x}^{8}$
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Hope this helps. - M

What is the slope- intercept form equation of the line that passes through (5, 7) and (8, 22)

kap26 [50]

M = (22 - 7)/(8 - 5) = 15/3 = 5
using point (5, 7) 
y - 7 = 5(x - 5) in point-slope form 
y - 7 = 5x - 25 
y = 5x - 18 in slope-intercept form.
