we have the inequality
step 1
Find out the first solution (positive case)
The first solution is all real numbers less than or equal to 1.20
Interval (-infinite,1.20]
step 2
Find out the second solution (negative case)
Multiply by -1 both sides
The second solution is all real numbers greater than or equal to -2.8
the interval [-2.8, infinite)
step 3
Find out the solution to the given inequality
The solution is
[-2.8, infinite) ∩ (-infinite,1.20]=[-2.8,1.20]
the solution is the interval [-2.8,1.20]
see the attached figure to better understand the problem
Answer:Cost per box: $95.94 ÷ (b)
Cost per tile: [$95.94 ÷ (b)]÷ (t)
First, we are trying to find the cost of each crate. Since the whole order was $95.94, we have to divide. The answer to the cost per box is $15.99.
Second, we are trying to find the cost of each of the tiles in the crates. Since they are in each crate, we divide the crate price from the tiles. The answer of the cost per tile is $.80.
Hope this helped you out!
Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x
40 and 80 are in the ratio 1:2 of 120.
Hope it helps!!!
Answer:
x=2 and y=7
Step-by-step explanation:
Step: Solvey=2x+3for y:
y=2x+3
Step: Substitute2x+3foryiny=3x+1:
y=3x+1
2x+3=3x+1
2x+3+−3x=3x+1+−3x(Add -3x to both sides)
−x+3=1
−x+3+−3=1+−3(Add -3 to both sides)
−x=−2
−x
−1
=
−2
−1
(Divide both sides by -1)
x=2
Step: Substitute2forxiny=2x+3:
y=2x+3
y=(2)(2)+3
y=7(Simplify both sides of the equation)
Answer:
4(s+1)
Step-by-step explanation:
(s+12) + (3s -8)
s+12+(3s-8)
s+12+3s-8
4s+12-8
4s+4
4(s+1)
