Answer: A. 7/21 = 1/x

Step-by-step explanation: 7/21 = 1/3 so x would be 3.

Answer:

2 1/4

Step-by-step explanation:

3/4 ÷ 1/3 = ?

(to divide fractions faster you flip the second fraction so:)

3/4 x 3/1 = 2 1/4

Answer:

-2.63 is bigger

Step-by-step explanation:

-2 5/7 is the same as -2.71428571428...

and when you compare a negative the smaller number is always greater than the bigger number because it is negative.

Answer:

a , b , d , e

Answer:

It would be 15

Step-by-step explanation:

because 5x3 equals 15.

Answer:

15 dollars

Step-by-step explanation:

because you have to multiply how many apples there are to how much each one cost. So the answer would be 5 x 3 equals 15 dollars

Answer:

150

Step-by-step explanation:

This is a word problem which should be tackled accordingly.

The sum of 48 and itself

= 48+48

= 96

It's half and half of its half

= 48/2 and (48/2)/2

= 24+ 24/2

= 24+12

= 36

Is added to 18

= 96+36+18

= 150

From the description above the entire sum is 150.

Answer:

138 I think

Step-by-step explanation:

math go brrr

Step-by-step explanation:

Let the initial population of a community be P0 and the population after time t is P(t).

If the population of a community is known to increase at a rate proportional to the number of people present at time t, this is expressed as:

[tex]P(t) = P_0e^{kt}[/tex]

at t = 5 years, P(t) = 2P0

substitute:

[tex]2P_0 = P_0e^{5k}\\2 = e^{5k}\\ln2 = lne^{5k}\\ln2 = 5k\\k = \frac{ln2}{5}\\k = 0.1386[/tex]

If the population is 9,000 after 3 years

at t = 3, P(t) = 9000

a) Substitute into the formula to get P0

[tex]9000 = P_0e^{0.1386\times 3}\\9000 = P_0e^{0.4158}\\9000 = 1.5156P_0\\P_0 = \frac{9000}{1.5156}\\ P_0 = 5938.24[/tex]

Hence the initial population is approximately 5938.

b) In order to know how fast the population growing at t = 10, we will substitute t = 10 into the formula as shown:

[tex]P(10) = 5938.24e^{0.1386(10)}\\P(10) = 5938.24e^{1.386}\\P(10) = 5938.24(3.9988)\\P(10) = 23,745.97[/tex]

Hence the population of the community after 10 years is approximately 23,746

Answer:

-(-4)(-6)*3/5(10+15)

when there is a (-) in front of an expression in parentheses, change the sing of each term in the expression.

4*(-6)*3/5*(10+15)

Add the numbers (10+15)

4(-6)*3/5*25

multiplying an odd number of negative terms makes the product negative

-4*6*3/5*25

reduce the number with the greatest common factor 5

-4*6*3*5

calculate the product

Answer:

Step-by-step explanation:

Answer:

18 at most.

Step-by-step explanation:

Answer:

-9

Step-by-step explanation:

the number is x

2x = 4x - - 18

2x = 4x + 18

-2x = 18

x = -9

Answer:

-9

Step-by-step explanation:

Let's solve your equation step-by-step.

2x=4x−(−18)

Step 1: Simplify both sides of the equation.

2x=4x+18

Step 2: Subtract 4x from both sides.

2x−4x=4x+18−4x

−2x=18

Step 3: Divide both sides by -2.

−2x/−2

= 18 /−2 x

=−9

Answer:

-9xy² - 6x²y + 5x

Step-by-step explanation:

The additive inverse of a polynomial is simply defined as the same polynomial but the difference is that the signs attached to each of the terms will change. This means that positive sign will change to negative while negative sign will change to positive.

Now, we are given the polynomial;

9xy² + 6x²y - 5x

Thus, from earlier description, additive inverse of this polynomial is;

-9xy² - 6x²y + 5x

You found the correct slope for Line 1, but Line 2 has a slope of (3 - 2)/(6-3) = 1/3.

If 2 lines are parallel, their slopes are the same; perpendicular and their slopes are opposite reciprocals (change the sign of the first slope, then divide 1 by it and you get the perpendicular line's slope). 1/3 is NOT the opposite reciprocal of 3 (because they have the same sign) and 1/3 is NOT equal to 3, so that makes the answer neither.

The slope for Line 3 is (3 - 1)/(1 - (-1)) = 2/2 = 1

The slope of Line 4 is (1 - (-1))/(4 - 2) = 2/2 = 1

1 = 1, so these lines are parallel

Answer:

C. hope it helps :)

Step-by-step explanation:

Answer:

When V is composed with r, the composite function is [tex]\frac{1}{48} \pi t^{6}[/tex]

When Vr6 shows that the volume is 9724. When the radius is increased to 6 inches.

Step-by-step explanation:

Volume is determined by [tex]cm^{3}[/tex] if the balloon is filled with air its volume will be increased and the composite function will represent the volume of the balloon. The radius of the balloon will rise in seconds. If t seconds are consumed to reach to a radius of 6 inches then the pie function is used to determine the volume.

Answer: B

Step-by-step explanation: It is greater or equal to -6 and less than or equal to 5.

Step-by-step explanation:

x+x+2+x+4=5(x+2)-18

3x+6=5x+10-18

x=7

Answer:

A) True

Step-by-step explanation:

[tex]-4,-1[/tex]

If we subtract the two numbers we get

[tex]-4-(-1)=-4+1=-3[/tex]

It can be seen that subtracting the two numbers changes the sign of one number by which we can algebraically subtract the numbers. Since, the addition of 1 shifts the number towards zero in the number line, the minus sign still remains.

So A)-4 -1 is true.

Answer:

y= 3x+6

Step-by-step explanation:

the equation to use for this problem is y= mx+b

m is the slope (3) and b is the y-intercept (0,6)

let's plug those numbers into the equation.

y= 3x+6

Answer:Step-by-step explanation:

a. Let x = number of months

Amount charged by Francis Lewis Gym = 150 + 10x

Amount charged by Clintonville Gym = 50 + 35x

Set each expression equal to the other to generate an equation to use in finding the number of months for which the cost of membership will be the same at both months

150 + 10x = 50 + 35x

Collect like terms

150 - 50 = -10x + 35x

100 = 25x

Divide both sides by 25

100/25 = x

4 = x

Answer: 4 months

b. Substitute x = 2 into each if the expression of the amount charged by each gym. The one that gives the lowest amount should be the one Mrs. Open should should join.

Amount charged by Francis Lewis Gym = 150 + 10x

= 150 + 10(2)

= 150 + 20

= $170

Amount charged by Clintonville Gym = 50 + 35x

= 50 + 35(2)

= 50 + 70

= $120

She should join the Clintonville Gym if she plans to join a gym for 2 months.

Answer: Clintonville Gym
