So the 180° rotation rule is (x,y) -> (-x,-y).

In this case, (-2,-3) would become (2,3), or B.

Leona spent 5/8 of 2/3 of her allowance on magazines. What fractions of her total allowance did she spend on magazines? What fra

Olegator [25]

Answer:

7x/12

Step-by-step explanation:

Let her entire allowance be represented by 'x'

She spent 5/8 of 2/3 of her allowance on magazines.

= 5/8×2/3

= 10/24

= 5/12

That 5/12 of 'x'

5/12x

Since her total allowance is x

She will be left with = x - 5/12x

x/1 - 5/12x

12x-5x/12x

= 7x/12

Hence she will be left with 7x/12

Find the value of angle marked x

lyudmila [28]

Based on the given diagram we see that all the exterior angle is in a straight line with the interior angle.

Using the known angle measure, we know that the shape has angles of measure, 123 degrees, 94 degrees, 79 degrees, and '180 - x' degrees

Also, the sum of all the angles in a quadrilateral, any four-sided shape, is 360 degrees.

Now using the knowledge gained lets set up the equation

$123 + 94 + 79 + 180 - x = 360\\476 - x = 360\\-x = -116\\x = 116$

Therefore x is 116 degrees.

Hope that helps!

Airida [17]

<h2><u>N-FACTORIAL!</u></h2>

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{1}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\: \bold{ \red{6!}= 6×5×4×3×2×1= \boxed{ \bold{ \blue{720}}}}$

Therefore, <u>the value of 6! is 720</u>.

<h3> $\mathbb{ \color{brown} \: PROBLEM } \: \: \bold{{ \color{brown}{2}}} :$ </h3>

$\mathcal{SOLUTION: }$

$\bold{3! \cdot 2! }\implies \bold{(3×2×1) \cdot( 2×1 )}$

$\: \: \: \: \: \: \: \: \: \: \: \: \implies \: \bold{ 6 \times 2} = \boxed{ \bold{ \blue{12}}}$

Therefore, <u>the value of the given expression is 12.</u>

members of the wide waters club pay 105 dollars per summer season, plus 9.50 each time they rent a boat. Nonmembers must pay 14.

WITCHER [35]

When handling problems of this nature make sure you setup the equations.
x = number of times they rent a boat.

Members
Cost = 105 + 9.50x
Non members because members don't have to pay the 105 we leave it out.
Cost = 14.75x

so now to determin when cost would be equal we set the two equations = to each other

105 + 9.50x = 14.75x

now solve for x

105 = 5.25x

20 = x

so they would have to rent 20 times to equal each other.
