Answer:

x=7

Step-by-step explanation:

63˚+70˚ = 133˚

180˚ - 133˚ = 47˚

(8x-9)˚ = 47˚

8x7=56

56-9=47˚

Answer:

<em>x = 7 </em>

Step-by-step explanation:

(8x - 9)° = 180° - ( 70° + 63° )

8x - 9 = 47

8x = 47 + 9

x = 56 ÷ 8  

<em>x = 7</em>

If h(-8), find 1/3*h(x) = x^2-5x+7
Lynna [10]

The value is 333

<h3>How to determine the function</h3>

From the information given, we have:

  • x = - 8
  • 1/3*h(x) = x^2-5x+7

Now, let's substitute the value of 'x' in the function:

1/3*h(x) = x^2-5x+7

1/ 3 × h(-8) = ( - 8)² - 5 ( -8) + 7

Make 'h ( -8)' the subject of formula

h ( -8) = \frac{( -8)^2 - 5(-8) + 7}{1/ 3}

h ( -8) = \frac{64 + 40+ 7 }{1/ 3}

Take the sum of the numerator

h ( -8) = \frac{111}{1/3}

Take the inverse of the denominator and multiply

h ( -8) = 111 × 3/ 1

h ( -8) = 333

We can see that through the substitute of the value of x as - 8, we get 333

Thus, the value is 333

Helpp!!<br> Simplify : [( 4 1/6 + 2 1/3 ) ÷ 4 1/3 ] - 1 1/2
Nadusha1986 [10]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{0}}}}}

Step-by-step explanation:

\sf{ [ (4 \frac{1}{6}  + 2 \frac{1}{3} )  \div 4 \frac{1}{3}] -  1\frac{1}{2} }

Convert the mixed numbers into improper fraction

\longrightarrow{ \sf{ [ ( \frac{25}{6}  +  \frac{7}{3} ) \div  \frac{13}{3}] -  \frac{3}{2}}}

Add the fractions : 25 / 6 and 7 / 3

While performing addition or subtraction of unlike fractions, you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fraction.

To do so, first take the L.C.M of 6 and 3 which results to 6

\longrightarrow\sf{ [( \frac{25 + 7 \times 2}{6} ) \div  \frac{13}{3} ] -  \frac{3}{2}}

\longrightarrow{ \sf{ [( \frac{25 + 14}{6} )  \div  \frac{13}{3}  ] -  \frac{3}{2} }}

\longrightarrow{ \sf{ [ \frac{39}{6}  \div  \frac{13}{3}] -  \frac{3}{2} }}

Multiply the dividend by the reciprocal of the divisor.

Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

\longrightarrow{ \sf{ [  \frac{39}{6}  \times  \frac{3}{13} ] -  \frac{3}{2}}}

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term

\longrightarrow{ \sf{ [  \frac{39 \times 3}{6 \times 13} ] -  \frac{3}{2}}}

\longrightarrow{ \sf{ [  \frac{117}{78}  ] -  \frac{3}{2} }}

\longrightarrow{ \sf{ \frac{3}{2}  -  \frac{3}{2} }}

While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same

\longrightarrow{ \sf{ \frac{3 - 3}{2} }}

Subtract 3 from 3

\longrightarrow{ \sf{ \frac{0}{2}}}

Divide 0 by 2

\longrightarrow{ \sf{0}}

Hope I helped!

Best regards!

Answer:

r \geqslant  - 5

Step-by-step explanation:

50 - 4r \leqslant 70

- 4r \leqslant 20

\frac{ - 4r}{ - 4}  \geqslant  \frac{20}{ - 4}

r \geqslant  - 5
