Answer:

<3=134.75

Step-by-step explanation:

8x+26=<4

Since angles 3 and 4 are supplementary, write an equation.

(8x+26)+<3=180

Subtract 26 from both sides

8x+<3=154

divide 8 to isolate the variable

x=19.25

`19.25+<3=154

<3=134.75 degrees

Sorry if this is wrong.

Answer:

82°

Step-by-step explanation:

i. 8x +26 = angle 5 (corresponding angles)

ii. angle 5 = -9x + 179 ( vertically opposite angles)

so,

8x+26= -9x +179 (from i and ii)

or, 17x= 153

therefore, x= 9

now,

angle3 + 8x +26= 180° (linear pair)

angle 3 = 180°- 72-26

hence, angle 3= 82°

Zina [86]

Expand the squared binomials:

$(2x+4)^2=4x^2+16x+16$

$(x-5)^2=x^2-10x+25$

Then

$(4x^2+16x+16)-(x^2-10x+25)=3x^2+26x-9=26x$

$\implies3x^2-9=0$

$\implies3x^2=9$

$\implies x^2=3$

$\implies x=\pm\sqrt3$

Which expression is equivalent to 7(p+2n)+n?

Illusion [34]

We actually need the choices but oh well, we can simpify and hopefuly it is one of the choices

remember the distributive property
a(b+c)=ab+ac
so

7(p+2n)+n
distribute first
7(p)+7(2n)+n
7p+14n+n
7p+15n is an equivilent expression

Ian has 12.2 ounce bottle of ketchip. He uses 1/20 of the ketchup every time he has a buffalo burger How many ounces of ketchup

tatiyna

If Ian uses 1/20 of the ketchup 4 times, this is equal to 4/20, or $\frac{4}{20}$ .

$\frac{4}{20}$ can be simplified to $\frac{1}{5}$ , which means we need to work out $\frac{1}{5}$ of 12.2

$\frac{1}{5}$ is equivalent to 20%, which as a decimal is 0.2

0.2 x 12.2 = 2.44 - however, this is how much he has used, and we need to figure out how much is left.

12.2 - 2.44 = 9.76

So, Ian has 9.76 oz remaining :)
