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

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

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

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

Katelyn has $1200.45 in her checking account. She spent $85.70 on groceries, paid her rent of $1000. Her grandmother sent her a check for her birthday for $85. How much money will be in Katelyn's account at the end of the month?

Answers

Answer:

$199.75

Step-by-step explanation:

Total money she has be x,

→ x = 1200.45 + 85

→ [ x = $1285.45 ]

Katelyn totally spend be y,

→ y = 85.70 + 1000

→ [ y = $1085.70 ]

Money left in Katelyn's account at the end of the month,

→ x - y

→ 1285.45 - 1085.70

→ $199.75

Hence, the money left is $199.75.

Answer: (3) 73/230

Step-by-step explanation:

You times whats in the brackets with 23 then remove the brackets which makes it = -71.3 - 23x = 5

Then i would swap the 23x and 5 around which makes it = 71.3 - 5 = 23x

subtract 71.3 - 5

-76.3 = 23x

Divide -76.3 by 23 (Use a calculator) =
