You can see the picture for the steps but I’m sure the answer is -72

Answer:

x = -72

Step-by-step explanation:

Using algebra:

⇒ [tex]-\frac{x}{8} -11 = 2[/tex]  (First add 11 to both sides of "=")

⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")

⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)

⇒ [tex]x = -72[/tex]

Which key correctly represents the information below?

A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13

Answers

Answer:

The correct answer is C) 11 | 2 = 112

Step-by-step explanation:

That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:

112, 112, 115, 118.

The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.

Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

C) 11 | 2= 112 the answer

Find the value of x and find whether the angles or supplementary or complementary.

Answers

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".

Walden gives the pizza delivery person an $8.00 tip, which was 12% of the cost of his pizzas. How much was the total amount that Walden spent? Round your answer to the nearest cent.

ANSWERS WITH WEIRD FILE THINGYS WILL BE REPORTED IMMEDIATLY

Answers

Answer:

$17

Step-by-step explanation:

Tip = $8.00

Pizzas cost:

First you have to do 12% of $8.00 which = $0.96

Then you have to add the $0.96 to the $8.00 which = $8.96

Total = $8.00 + $8.96

         = $16.96

then round it to nearest cent which is $17

Answer:

$74.67

Step-by-step explanation:

$8 was 12% of the cost of the pizzas, so we have to add that to the initial cost. The initial cost can be found by (8*100)/12, which would be $66.67. Since we need to find the total amount of money spent, we have to add the initial cost of pizzas and the $8 tip, which is 12% of that. Final answer is $74.67
