The "D" in number 1 is really "1D" so when we combine like terms, we get our final answer:
4D+2
If we do the same thing with number 2, we get:
14x+4
The correct answer of
if x=4 is 272.
to solve the equation if x equals 4, you must substitute the x of the 4.
then solve by order of operations.
solve what is inside the parentheses first
then do the multiplication of the factors
then the final step, adding, to get the solution of 272
Answer:
The value of x is 5 therefore we'll change x to 5 and so the the value of y to 7. And follow the formula x+y=
Step-by-step explanation:
Answer:
The airplane ascends meters in one second.
Step-by-step explanation:
Given that the airplane ascends () meters in seconds, we calculate the ascent rate of the airplane by simple rule of three:
The airplane ascends meters in one second.
The volume of the pyramid is calculated by multiplying the area of the base by the height of the figure. For this item, for the figures to have the same volume,
V = B1H1 = B2H2
Then, we substitute the given values, and since we are not given the shape of the base and the volume of the entire figure, we can just solve it through the way below.
(20 in)(21 in) = (x in)(84 in)
The value of x in the problem is 5 inches.
