36 red cars108 grey cars========================================================
Work Shown:
The ratio 2 red : 6 grey reduces to 1 red : 3 grey when we divide both parts by 2. For every 1 red car, there are 3 grey cars. There are triple as many grey compared to red.
Let x be the number of red cars. Since there are 3 times as many grey cars, this means 3x represents the number of grey cars.
The total number of cars can be represented by the expression x+3x = 4x
Set this equal to the total number of cars (144) and solve for x
4x = 144
x = 144/4
x = 36
There are 36 red cars.
Subtract that value from 144 to find 144-36 = 108 grey cars.
----------------------------------------
An alternative way to solve:
(2 red)/(6 grey) = (x red)/( (144-x) grey)
2/6 = x/(144-x)
2(144-x) = 6x .... cross multiply
2*144 - 2*x = 6x
288 - 2x = 6x
288 = 6x+2x
288 = 8x
8x = 288
x = 288/8
x = 36
If there are 144 vehicles in the parking lot, then 36 cars are red.
Also, 144 - x = 144 - 36 = 108 cars are grey.

Answer:
the handle will end up on the left side
Step-by-step explanation:
The cup is rotated 180 degrees clockwise. Therefore, I assume the rotation is about the center of the bottom of the cup. Also, only the cup is rotated, not the saucer (although this makes no difference in this problem).
The result is that the handle will end up on the left side. The cup will still be right side up.

Identify the two tables which represent quadratic relationships.
Answer: Second to the top and the bottom tables.
Step-by-step explanation:
Fabiola’s dog is 5 pounds heavier than one-third of the weight of Luisa’s dog. Fabiola’s dog weighs 23 pounds. Use the diagram to write an equation to represent the dogs’ weights. Let f represent the weight of Luisa’s dog.
A long rectangle is the top section. 2 smaller rectangles are the bottom section.
The top section represents
.
The bottom section represents
.
The equation is
answer;
1. the top section represents, 23 pounds. (d)
2. the bottom section represents, 5 + 1/3f. (a)
3. the equation is, 23 = 1/3f + 5. (b)
hope this helps!
1/3x+5=23 is equation to represent the dogs’ weights and weight of Luisa' dog is 54 pounds.
What is Equation?Two or more expressions with an Equal sign is called as Equation
Let f represent the weight of Luisa’s dog.
Fabiola’s dog is 5 pounds heavier than one-third of the weight of Luisa’s dog.
Luisa' dog weight: x pounds
One-third of the weight of Luisa’s dog: 1/3x pounds
5 pounds heavier than one-third of the weight of Luisa’s dog : 1/3x+5
Fabiola's dos weight: 1/3x+5pounds that is 23 pounds.
1/3x+5=23
Subtract 5 from both sides
x/3=18
x=54 pounds
Hence, 1/3x+5=23 is equation to represent the dogs’ weights and weight of Luisa' dog is 54 pounds.

Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
Given the expression 5 p + 6 = 7,
to know the value of variable p. we need to make p the subject of the formula as shown;
Given 5 p + 6 = 7
Step 1:
Subtract 6 from both sides
5p+6-6 = 7-6
5p = 7-6
Step 2:
We will then divide both sides by the coefficient of p i.e 5 to have;
5p/5 = (7 - 6)/5
p = (7 - 6)/5
Hence, the correct expression of variable p is p = (7 - 6)/5.
