Answer:
Martina 29, Scott 23 and Jim 69.
Step-by-step explanation:
We are told that:
Martina served six more X orders than Scott (X+6).
So, Scott served X orders.
And Jim served 3 times X order as Scott.
We will have then:
X + (X+6) + 3X = 121
5X + 6 = 121
5X = 121 - 6
5X = 115
X = 115/5
X = 23
So, Scott served 23 orders, Martina 29 and Jim 69.
$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.
$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.
The dependent variable would be b (affected by the change of n) and the independent variable would be n (affects b). The equation would be
b = 12n.
Answer:
The actual space shuttle is 66 feet tall
Step-by-step explanation:
scale of 1 inch : 12 feet represent the scale of a space shuttle.
It means it has a representation of 1 inch on paper then actual = 12 feet.
But then if the paper(model) changes to 5.5 inches. The actual representation on land will be
Let me write out the equation
1 inch = 12 feet
5.5 inch =( 5.5 inch *12 feet)/1 inch
5.5 Inch= 5.5 * 12 feet
5.5 inch = 66 feet
