If 3 centimeters is equal to 30 millimeters, how many centimeters are in 140 millimeters?
Answer:
14
Step-by-step explanation:
divide by 10
Answer:
14
Step-by-step explanation:
You have the proportion:
3 cm: 30 millimeters
divide both sides by 3
1 cm: 10 millimeters
Then, multiply both sides by 14
14cm: 140 millimeters
So 14 centimeters are in 140 millimeters

y= -2x-2, -2x+4y=12 please help i'll give 100 points.
solve it in substitution
Answer:
x = -2 and y= 2
Step-by-step explanation:
y=-2x-2 and -2x+4y=12
Substitute: -2x+4(-2x-2)=12
Distribute: -2x-8x-8=12
Combine like terms: -10x-8=12
Simplify: -10x=20
20/-10 = -2
Use that value to solve for y
y=-2x-2
Substitute x value: y=-2(-2)-2
Simplify: y=2

Jackie's commute is 15 minutes longer than Laura's. If Laura drives 12 minutes for every 17 minutes Jackie drives what are both Jackie's and Laura's drives?
Answer:
Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]51\ \text{minutes}[/tex]
Step-by-step explanation:
Laura's commute is [tex]x\ \text{minutes}[/tex]
Jackie's commute is
[tex]x+15[/tex]
Laura drives 12 minutes for every 17 minutes Jackie drives so
For every minutes Laura drives Jackie drives [tex]\dfrac{17}{12}\ \text{minutes}[/tex]
So,
[tex]\dfrac{17}{12}=\dfrac{x+15}{x}\\\Rightarrow 17x=12x+180\\\Rightarrow 5x=180\\\Rightarrow x=\dfrac{180}{5}\\\Rightarrow x=36\ \text{minutes}[/tex]
Hence, Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]36+15=51\ \text{minutes}[/tex].

Answer:
-40[tex]\leq[/tex]x
Step-by-step explanation:
Solve the inequality using the properties of equality.
First, add 60 to both sides
-440[tex]\leq[/tex]11x
Then, divide both sides by 11
-40[tex]\leq[/tex]x
So, -40 must be less than or equal to x.
A rectangle has a perimeter of 64.
Let x equal the width of the rectangle.
Let y equal the area of the rectangle.
Which equation can be used to find the area of the rectangle?
A. y = x² - 64x
B. y = -x² + 64x
C. y = x² - 32x
D. y = -x²+ 32x
Answer:
You can use option (D) to find the area of rectangle
(D) y = - x²+32x

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]
it is given that
area of the rectangle = y
width of the rectangle = x
so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]
perimeter = 64
What is the perimeter of a rectangle?Perimeter is the sum of all four sides of the rectangle.
we can say that,
2(length + breadth) = 64
[tex]2( \frac{y}{x} + x)=64\\\\[/tex]
[tex]\frac{y}{x} + x= 32[/tex]
[tex]\frac{y + x^{2} }{x} = 32[/tex]
[tex]y+x^{2} = 32x[/tex]
[tex]y = -x^{2} +32[/tex]
therefore, the expression for the area of the rectangle,
[tex]y = -x^{2} +32[/tex]

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 900 * 3^m, where m is the number of months after the number of visitors was measured. Evaluate the expression for m=-2. What does the value of the expression represent in the situation?
Answer:
[tex]900\times 3^m[/tex] = 100
Step-by-step explanation:
The number of visitors is modeled by the expression [tex]900\times 3^m[/tex]
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,
[tex]900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100[/tex]
At m = -2, the value of the above expression is equal to 100.

we know that (x-5) and (y-6) must add up to 129 because 180-51 is 129
now let's plug in the values to see
51-5= 66 63-6 = 57
57+66 is 123, not this one, let's repeat the same step
77-5 is 72, 63-6 is 57, these added is 129

Which of the following equations could represent a town with an initial population of 875 people and an annual growth rate of approximately 2%?
A. y = 875 ⋅ x1.02
B. y = 875 (1.02)x
C. y = 875(2)x
D. y = 875 • 1.02x
Answer:
B
Step-by-step explanation:
1+0.02=1.02
875(1.02)^x
The equation is y = 875 (1.02)ˣ represents a town with an initial population of 875 people and an annual growth rate of approximately 2%. which is the correct answer would be an option (B).
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
Initial population = 875 people
Growth rate = 2%
The growth rate is the base of the exponent instead of the initial population.
As per the given situation, the required equation would be as:
y = 875 (1 + 2%)ˣ
y = 875 (1 + 0.02)ˣ
y = 875 (1.02)ˣ
In this equation, x represents the number of years after the initial population of 875 people.
Hence, the correct answer would be option (B).

Answer:
y = 17/2
Step-by-step explanation:
7y − 4 = 9y + 13 − 4y
Simplify both sides of the equation.
7y - 4 = 5y + 13
Subtract 5y from both sides.
2y - 4 = 13
Add 4 to both sides.
2y = 17
Divide both sides by 2.
y = 17/2
