Answer:
(x + 130, y - 55)
Step-by-step explanation:
If the southeast corner of the pole barn is the only reference point, it only requires this one point and not the size of the barn.
Let's set this up first: West/South= Negative x/y, and East/North= Positive x/y.
Currently, the corner is at -50, 25. The corner needs to be moved to 80, -80.
For x: |-50|+80=130
For y: |25|+(-80)=-55
<u>The formula for this is</u> |a|+b=c.
This leaves it with (x <em>+</em> <em>130</em>, y <em>- 55</em>)
okay so basically its an increase of 3.5% of 25 dollars and 67 cents.
So
basically
(25.67)* .035 -----> To get .035, you will need to move the decimal to the left twice to make it into a decimal to get the percentage of the total amount.
So the total of that amount would be
89 cents ( ignore numbers after 9 because your just looking at the 2 first number after you did your equation).
Then you add the total amount ( The amount for the meal) + The TAX
So you will get 25.67 + 89 = 26.56
If you got any more questions of what I said ( because it's confusing). Tell me!
ANSWER: $26.56
Answer:
D. All three chose a valid first step toward solving the equation.
Step-by-step explanation:
Aaron, Blaine, and Cruz are solving the equation 4/7 (7 − n) = −1. Aaron started his solution by multiplying both sides of the equation by 7/4 . Blaine started by using the distributive property to multiply 4/7 by both 7 and −n. Cruz started by dividing both sides of the equation by 4/7 .
Which of the following is true?
A. Blaine and Cruz made an error in picking their first steps.
B. Cruz made an error in picking his first step.
C. All three made an error because the right side equals -1.
D. All three chose a valid first step toward solving the equation.
Given:
4/7(7 - n) = -1
Aaron:
4/7(7 - n) = -1
Multiple both sides by 7/4
4/7(7 - n) * 7/4 = -1 * 7/4
7 - n = -7/4
- n = -7/4 - 7
- n = (-7-28)/4
- n = -35/4
n = 35/4
Blaine:
4/7(7 - n) = -1
4/7(7 - n) × 7 = -1 × 7
4(7 - n) = -7
28 - 4n = -7
-4n = -7 - 28
- 4n = - 35
n = -35/-4
n = 35/4
Cruz:
4/7(7 - n) = -1
Divide both sides by 4/7
4/7(7 - n) ÷ 4/7 = -1 ÷ 4/7
4/7(7 - n) × 7/4 = -1 × 7/4
7 - n = -7/4
- n = (-7-28)/4
- n = -35/4
n = 35/4
D. All three chose a valid first step toward solving the equation.
Answer:
x = - 10
Step-by-step explanation:
Average is calculated as
average = 
, thus
= 3
Multiply both sides by 3 to clear the fraction
19 + x = 9 ( subtract 19 from both sides )
x = - 10
