Answer 1

Answer:

x = 20

Step-by-step explanation:

2x + 2x + 10 = 90

4x + 10 = 90

4x = 80

x = 20

Answer 2

Answer:

Angle AOB is made up of angle AOC and COB.

AOC + COB = AOB

Since AOB is a right angle, it is 90°.

Using the values given, AOC = [tex]2x[/tex] and COB = [tex]2x+10[/tex].

Therefore,

[tex]2x+2x+10=90[/tex]

Subtract 10 from both sides:

[tex]2x+2x+10-10=90-10[/tex]

[tex]2x+2x=80[/tex]

[tex]4x=80[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4} =\frac{80}{4}[/tex]

[tex]x=20[/tex]

Answer:

359.74

sam has more

Step-by-step explanation:

372 - 12.26 = 359.74

372 > 12.26

Answer:

372 - 12.26 = 359.84

372 > 12.26

The difference is 349.84, and I know this because I substracted 12.26 from 372. I know that Sam has more money because 12.26 is less than 372

For questions #9 - 11 "finding the slope" of a linear (straight) line, recall the "tools" that we can use:

1) Given a Graph: Slope or "m" = rise/run from one (x, y) point to a second (x, y) point on the line

2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1

3) Given a "Table of Values": Choose any two (x, y) points in the table, then calculate the slope using the slope formula - Slope or "m" = y2 - y1 / x2 - x1

Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

Answer:

27

Step-by-step explanation:

Answer:

$27

Step-by-step explanation:

substitute the value of p (price of the package of henna powder) which has been given as $12 and the value of s (price of the squeeze bottle) which has been stated as $3 into the equation from part b).

since the equation is 3(p-5) + 2s

write 12 instead of p, and 3 instead of s.

then solve the equation.

= 3(12-5) + 2(3)

= 3(7) + 2(3)

= 21 + 6

= 27

I don’t know how I should find the missing angles. But I can solve for X. So first we need to combine like terms so we add 2x, x and x which gives us 4x. And we set up our problem like this: 4x + 24=180. So we then subtract 24 from 180 and get 156 then divide 4x and 156, which leaves us with x=39
