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]

It is 15.4 I solved it

Answer:

15.4

Step-by-step explanation:

What i did was i did it in standard form. But, what i did was the 7 x 2 which is 14 then carried the 1 to the ones place. Then, i did 7x2 + 1 to get 15. 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.

Heres the work:

Answers

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

1) Write an equation that can be used to solve for the missing angles. (5pts)

2) Then Solve the equation for find the value of X. (Make sure to explain or show all the steps to get full Credit)

Answers

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

Answers

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

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
