Answer: See explanation
Step-by-step explanation:
Let the number of callories that are in one cheeseburger be = x
Let the number of calories that are in one medium frys be = y
Therefore, the question can be formed into an expression as:
Jerry = 1x + 1y = 1200
Joe = 2x + 1y = 1260
x + y = 1200 ....... i
2x + y = 1260 ....... ok
Subtract equation i from ii
x = 60
Therefore, number of callories that are in one cheeseburger is 60 calories
Since x + y = 1200
60 + y = 1200
y = 1200 - 60
y = 1140 calories
The number of calories that are in one medium frys is 1140 calories
The speed 217 miles per hour using dimensional analysis to convert to feet per minute is; 19096 ft/min
<h3>How to use Dimensional Analysis?</h3>
From dimensional analysis, we know that;
1 mile = 5280 feet
1 hour = 60 minutes
Thus;
1 mile/hr = 88 feet/min
Since conversion from mph to ft/min is, 1 mile/hr = 88 feet/min
Then, 217 mile/hr = (217 mile/hr/1 mile/hr) * 88 feet/min
⇒ 19096 ft/min

The solution for x in the equation 3ax - n/5 = -4 is x = -4/3a + n/15a.
<h3>What is the solution for x in the given equation?</h3>
3ax - n/5 = -4
To solve for x, isolate the term that contains x.
3ax - n/5 = -4
3ax = -4 + n/5
Divide each term by the coefficient of x and simplify
3ax/3a = -4/3a + (n/5)/3a
x = -4/3a + (n/5)/3a
multiply (n/5) by the reciprocal of 3a
x = -4/3a + (n/5) × 1/3a
x = -4/3a + n/15a
Therefore, the solution for x in the equation 3ax - n/5 = -4 is x = -4/3a + n/15a.
