Answer:
The weight of grapefruit is now 80 pound.
Step-by-step explanation:
Consider the provided information.
Let the x is the weight loss. The weight of grapefruit is 100 pounds and water is 92%. After evaporation water is 90%.
Thus the weight loss is:





Hence, the weight loss is 80 pounds.
Therefore, New weight is 100 - 20 = 80 pounds
The weight of grapefruit is now 80 pound.
Answer:
The length of the insect in decimeters is: 0.035 decimeters
Step-by-step explanation:
The metric table help us to know:
1 decimeter =100 millimeters
To answer the question we need to know how many decimeters are 3.5 millimeters, so:

The length of the insect in decimeters is: 0.035 decimeters
Answer:
(- 1, 5 )
Step-by-step explanation:
Using the method of substitution.
Given the 2 equations
3x + 2y = 7 → (1)
x - 4y = - 21 → (2)
Rearrange (2) expressing x in terms of y by adding 4y to both sides.
x = 4y - 21 → (3)
Substitute x = 4y - 21 into (1)
3(4y - 21) + 2y = 7 ← distribute and simplify left side
12y - 63 + 2y = 7
14y - 63 = 7 ( add 63 to both sides )
14y = 70 ( divide both sides by 14 )
y = 5
Substitute y = 5 into (3)
x = (4 × 5) - 21 = 20 - 21 = - 1
Solution is (- 1, 5 )
Plug in -1 for x and work it ou'
g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8
= -1 + 6 - 12 + 8
= 1
1 * 12 = -40
12 = -40
Since its not possible for twelve to equal negative-forty, than there is no answer for this equation.
