Need answer for this IXL

Answer:

[tex] J. \:\:71\degree[/tex]

Step-by-step explanation:

CNWK is a [tex] ||^{gm} [/tex]

[tex] \therefore m\angle C + m\angle K = 180\degree [/tex]

(Adjacent angles of a parallelogram)

[tex] \therefore (4a+7)\degree + (7a-3)\degree = 180\degree\\\\

\therefore (4a+7+7a - 3)\degree = 180\degree\\\\

\therefore (11a+4)\degree = 180\degree\\\\

\therefore 11a+4 = 180\\\\

\therefore 11a= 180-4\\\\

\therefore a= \frac{176}{11}\\\\

\therefore a= 16\\\\

\because m\angle C = (4a+7)\degree\\\\

\therefore m\angle C = (4\times 16+7)\degree\\\\

\therefore m\angle C = (64+7)\degree\\\\

\huge \orange {\boxed {\therefore m\angle C = 71\degree}} \\\\

Answer:

can i see the numbers

Step-by-step explanation:

there is no picture

Let's solve for x

Y=x-5

step 1:flip the equation

x-5=y

step 2:Add 5 to both sides

x-5+5=y+5

x=y+5

answer :x=y+5

Given equation:

Need to show that q1+q2 = 0

Bringing the equation into standard form of ax² + bx + c = 0:

Sum of the roots:

Product of the roots:

We see that q1 and q2 are opposite numbers, therefore their sum equals zero:

Answer:

x = - 10.5

Step-by-step explanation:

Given that y is inversely proportional to x² then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion

To find k use the condition y = 8 when x = 3.5 , then

8 = [tex]\frac{k}{3.5^2}[/tex] ( multiply both sides by 3.5²

8 × 3.5² = k , that is

k = 98

y = [tex]\frac{98}{x^2}[/tex] ← equation of proportion

When y = [tex]\frac{8}{9}[/tex] , then

[tex]\frac{8}{9}[/tex] = [tex]\frac{98}{x^2}[/tex] ( cross- multiply )

8x² = 882 ( divide both sides by 8 )

x² = 110.25 ( take the square root of both sides )

x = ± [tex]\sqrt{110.25}[/tex] = ± 10.5

Thus x = - 10.5 ← is the negative value of x

Answer:

This is NEGATIVE. Think of negative as you falling down a mountain, like in that kind of shape, and positive you going up a mountain, undefined as just a line that has no "tilt" and only goes straight up or down, and zero slopes are just horizontal lines. hope this helps.

Step-by-step explanation:

Answer:

$2 for soda and $1.5 for a bottle of water

Step-by-step explanation:

You start by turning both situations into an equation

Let x represent bottles of water and y represent sodas

Saturday:

[tex]40x+25y=110[/tex]

Sunday:

[tex]50x+45y=165[/tex]

You then want to start by cancelling out the x in this equation, to do that you want 40x to become -50x so you:

50÷40=1.25

You then times the whole equation by -1.25

40x+25y=110

×-1.25

-50x+-31.25y= -137.5

You then add this equation by Sunday's equation

50x+45y=165

-50x+-31.25y=-137.5

          13.75y=27.5

You now want to make the co-efficient of y a whole number (for example 15) so you divide 15/13.75=1.09 recurring

13.75y=27.5

×1.09 recurring

    15y=30

15y/15=30/15

     y=2

Now that we know y = 2

We can use either Saturday or Sunday's equation to figure out the value of [tex]x[/tex]

Let's use Sunday's:

50x+45×2=165

50x+90=165

50x+90-90=165-90

50x/50=75/50

x=1.5

Let's check our answer with Saturday's equation

40×1.5+25×2=110

This equation is correct

Therefore the prices for each beverage option is $1.5 for a bottle of water and $2 for a soda

Answer:

Step-by-step explanation:

Step one:

given

percentage of discount= 30%

Regular price of jeans= $49.99

Required:

the price of the jeans after the discount is deducted

Step two;

let us solve for the amount of the 30% discount

=30/100*49.99

=0.3*49.99

=14.997

=$15 approx.

Hence the deduction in discount is $15

therefore the sale price after the discount is

=49.99-15

=$35

Answer:

x= 22

x+44=3x

-x. -x

44=2x

÷2. ÷2

22=x

Based off picture

Answer:

x = 22

Step-by-step explanation:

If l and m are parallel, then

(2x + 60) and 130° are same- side interior angles and are supplementary, thus

2x + 6 + 130 = 180 , simplify

2x + 136 = 180 ( subtract 136 from both sides )

2x = 44 ( divide both sides by 2 )

x = 22
