To find the number of rows of trees in the parcel, we set up the equation (Number of rows) * (3x - 2) = 24x - 16. By solving this equation for the number of rows, we find that it equals (24x - 16) / (3x - 2).
The question is about determining the number of rows in a rectangular parcel of land with trees. It is given that each row has 3x-2 trees and the total is 24x-16 trees. We can set an equation based on this information: (Number of rows) x (Number of trees in each row) = Total number of trees. This gives us the following equation: (Number of rows) * (3x - 2) = 24x - 16. Solving for the number of rows, we divide each side of the equation by 3x - 2. Hence, the number of rows equals (24x - 16) / (3x - 2).

A. 6a4b2
B. 2a4b7
C. 4a2b2
D. 3a4b
Answer:
D.
Step-by-step explanation:
We have: in order to simplify this expression, we have to apply the rule of the exponents.
This rule says that:
If you have the same base, the exponents can be added.
We can rewrite the expression as
Then we have:
Finally:
The correct option is D.
Answer:
the total amount she paid for the cake, $82.5
Step-by-step explanation:
As per the statement:
Melissa bought a cake that cost $75.
⇒Cost of cake = $75
It is also given that:
The sales-tax rate is 10 percent.
then
Sale tax she gave on cake =
We have to find the total amount she paid for the cake.
Substitute the given values we have;
therefore, the total amount she paid for the cake, $82.5
Each chair or table requires between 0.2 and 1 gallon of paint to be painted.
What is the equivalent expression?
Equivalentexpressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
To find out how many gallons of paint are used to paint each piece of furniture, we need to divide the total amount of paint used by the total number of pieces of furniture.
Let x be the amount of paint used to paint one chair or table, in gallons.
Then, for 20 chairs and 5 small tables, the total amount of paint used is:
4 gallons = 20x + 5x
Simplifying this equation, we get:
4 gallons = 25x
Dividing both sides by 25, we get:
x = 0.16 gallons
Therefore, it takes 0.16 gallons of paint to paint each chair or table. Since we are looking for whole numbers, we can round this to the nearest whole number to get:
0.16 gallons ≈ 0.2 gallons
Hence, each chair or table requires between 0.2 and 1 gallon of paint to be painted.

north. Find the magnitude of the
car's resultant vector.
Answer:
73.2km
Step-by-step explanation:
first you have to decompose 46 km into y and x components.
x=sin40°*46km
x=0.64*46km
x=29.44km
y=cos40°*46km
y=0.76*46km
y=34.96
now you add the y components together
32+34.96=66.98
finally use Pythagorean thereom to find the resultant vector.
a*a+ b*b=c*c
66.98*66.98+29.44*29.44=c*c
c*c= 4486.3+866.7
c=√5353
c=73.2 km this is the approximate value
