Enter an inequality that represents the situation.
The correct answer is:
3x + 1.5y ≤ 25
Explanation:
The variable x represents the number of board games. Each one weighs 3 pounds, which gives us the expression 3x.
The variable y represents the number of remote control cars. Each one weighs 1.5 pounds, which gives us the expression 1.5y.
The sum of their weights gives us the expression 3x+1.5y.
Since the box can hold no more than 25 pounds, the inequality must be less than or equal to:
3x+1.5y≤25
Answer:
THE ANSWER IS 3x+1.5y ≤ 25
Step-by-step explanation:
b. x=-6 and x=-1
c. x=-1 and x=7
d. x=1 and x=6
Answer:
C
Step-by-step explanation:
The equation is
LCM of the denominator on the left side gives us:
Cross multiplying and arranging gives us:
This is a binomial, to factor this, we have to think of 2 numbers that multiplied gives us [the constant term] and added gives us [the coefficient of x].
The two numbers are: and .
Now we can write:
Hence, either OR . This gives us two solutions, and . Answer choice C is correct.
Answer:
The area of a rectangle is 42 units ².
Step-by-step explanation:
As the diagram is given below.
Distance Formula
As the rectangle with vertices at A (4, 3), B(11, 3),C (11, 9), and D (4, 9).
Take A (4, 3) to B(11, 3)
AB = 7 units
As take B(11, 3) to C (11, 9).
BC = 6 units
As take C (11, 9) toD (4, 9).
CD = 7 units
As take D (4, 9) to A (4, 3)
DA = 6 units
Thus
AB = DC= 7 units
AD = BC = 6 units
Formula
Area of rectangle = Length × Breadth
Length = 7 units
Breadth = 6 units
Put value in the above
Area of rectangle = 7 × 6
= 42 units ²
Therefore the area of a rectangle is 42 units ².
