Answer:c
Explanation: well 79.95-20%=63.96
Answer:20mph
Step-by-step explanation:
speed of plane = x mph
Speed of plane with wind = 485 mph
So therefore, speed of wind =
485 - x
Speed of plane against wind = 445 mph
So therefore, speed of wind =
x - 445
So therefore, equating the 2 equations of speed of wind
485 - x = x - 445
Collect like terms
485 + 445 = x + x
930 = 2x
2x = 930
x = 930/2 = 465 mph
Speed of wind = x = 465mph
So we put this value on any of the equations for speed of wind
Speed of wind = x - 445 = 465 - 445
= 20 mph
So therefore, speed of wind = 20mph
Answer:
<em>(a), (d)</em>
Step-by-step explanation:
The number of teaspoons of sugar that Mr. P. consumes is = 56.7 teaspoons.
<h3>Calculation of total sugar quantity</h3>
The total amount of cola taken is 8-ounce
To covert ounce to grams , the following is carried out;
1 ounce =28.35g
8 ounce = X
Xg = 8 × 28.35
X = 226.8g
But one teaspoon = 4 grams
X teaspoon = 226.8g
cross multiply to solve for x
X = 226.8g/ 4
X = 56.7 teaspoons
Therefore, the number of teaspoons of sugar that Mr. P. consumes is = 56.7 teaspoons.

<h2><u>ANSWER </u></h2>
x= 3
Step-by-step explanation:
=> -4x – 5 + 2x = -11
=> -2x = -11+5
=> -2x = -6
=> x= 6/2
=> x= 3
