What should you multiply the first equation (top equation) by in order to eliminate the variable y when the two equations are added together? {x+2y=5{3x-4y=8
Answers
2
Explanationgiven
[tex]\begin{gathered} x+2y\rightarrow equation(1) \\ 3x-4y=8\rightarrow equation(2) \end{gathered}[/tex]Step 1
a) to eliminate the y variable we have
[tex]\begin{gathered} 2y \\ -4y \end{gathered}[/tex]in order to be eliminated both terms must have the same value and different sign,in other words the addition must equla zero, so weed a number (a) that makes the term from teh first equation equals (4y)
so
[tex]\begin{gathered} (2y*a)-4y=0 \\ 2ay=4y \\ so \\ 2a=4 \\ divide\text{ both sides by 2} \\ \frac{2a}{2}=\frac{4}{2} \\ a=2 \end{gathered}[/tex]therefore, the first equation should be multiplied by 2

Every 3 months, homeowners in boice pay $46.00 for service provided by the city. how much do homeworkers pay in one year? (1 year = 12 months)
Answers
We were told that in every 3 months, homeowners in boice pay $46.00 for service provided by the city.
Given that there are 12 months in a year, the number of 3 months in a year would be

This means that $46 would be paid 4 times in a year.
Thus, the amount that the homeworkers would pay in a year is
4 * 46 = $184
Thomas is buying football jerseys for his high school football team. Thecost of each jersey is $80. The company also charges a processing fee of$100.Write an equation that represents Thomas' total cost for purchasing xnumber of jerseys.What is Thomas' total cost, if he buys 55 jerseys?
Answers
Thomas is buying football jerseys for his high school football team.
The cost of each jersey is $80.
The company also charges a processing fee of $100.
We could write an equation that models Thomas's total cost for purchasing x
number of jerseys.
Since for every x jerseys Thomas buys, he pays
[tex]80x\text{ dollars}[/tex]But he also has to pay the company's processing fee, this is independent of the quantity bought.
So, the total cost for buying x number of jerseys is;
[tex]y=80x+100\text{ dollars}[/tex]ii. What is Thomas's total cost, if he buys 55 jerseys?
We can use our formula,
[tex]\begin{gathered} y=80x+100\text{ , when x =55, we have;} \\ y=80(55)+100 \\ y=4400+100 \\ y=4500\text{ dollars} \end{gathered}[/tex]Therefore, Thomas's total cost for 55 jerseys is $4500

How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.Next, we would determine the common difference by using the 25th term of this arithmetic sequence:
-48 = 0 + (25 - 1)d
-48 = 24d
d = -48/2
d = -2.
For the nth term of this arithmetic sequence with -10, we have:
aₙ = a₁ + (n - 1)d
-10 = 0 + (n - 1)-2
-10 = -2n + 2
2n = 12
n = 6.
For the 8th term of this arithmetic sequence, we have:
a₈ = a₁ + (n - 1)d
a₈ = 0 + (8 - 1)-2
a₈ = -14.
For the nth term of this arithmetic sequence with -20, we have:
aₙ = a₁ + (n - 1)d
-20 = 0 + (n - 1)-2
-20 = -2n + 2
2n = 22
n = 11.
For the 19th term of this arithmetic sequence, we have:

A circular garden with a radius of 4 ft is planted in the center of a 10 ft square. The part of the square that is NOT the garden is covered with small white rocks. what is the area of the region covered with white rocks?
Answers
First, draw a diagram to visualize the situation:
The area of the region covered with small rocks can be found by subtracting the area of the circle from the area of the square.
The area A_s of a square with side L is given by:
[tex]A_s=L^2[/tex]And the area A_c of a circle with radius r is given by:
[tex]A_c=\pi r^2[/tex]Replace r=4ft and L=10ft into the equations to find the area of the circle and the square:
[tex]\begin{gathered} A_s=(10ft)^2=100ft^2 \\ A_c=\pi(4ft)^2=16\pi ft^2\approx50.265ft^2 \end{gathered}[/tex]Finally, subtract the area of the circle from the area of the square to find the area of the region covered with rocks:
[tex]A=A_s-A_c=100ft^2-16\pi ft^2\approx49.7ft^2[/tex]Therefore, the area of the region covered with rocks is exactly 100-16π square feet, which is approximately equal to 49.7 square feet.

How much dobags of bagels and packages of cream cheese cost?

Answer:
Explanation:
Let the price of one bag of bagel = b
Let the price of one package of cream cheese = c
3 bags of bagels and 3 packages of cream cheese costs $16.50.
[tex]3b+3c=16.50\cdots(1)[/tex]5 bags of bagels and 2 packages of cream cheese costs $22.25.
[tex]5b+2c=22.25\cdots(2)[/tex]Thus, we derive a system of two linear equations which we then solve for b and c.
[tex]\begin{gathered} 3b+3c=16.50\operatorname{\cdots}(1) \\ 5b+2c=22.25\operatorname{\cdots}(2) \end{gathered}[/tex]Multiply equation 1 by 5 and equation 2 by 3.

[tex]9c=15.75[/tex]Divide both sides by 9:
[tex]\begin{gathered} \frac{9c}{9}=\frac{15.75}{9} \\ c=1.75 \end{gathered}[/tex]Next, substitute c=1.75 into equation 1.
[tex]\begin{gathered} 3b+3c=16.50 \\ 3b+3(1.75)=16.50 \\ 3b=16.50-3(1.75)=11.25 \\ b=\frac{11.25}{3}=3.75 \end{gathered}[/tex]The price per bag of bagel is $3.75 and the price per package of cream cheese is $1.75.

A) Between 3 and 4, but closer to 3======================
First, find the cubes of 2, 3 and 4 and then compare them with 30.
2³ = 8,3³ = 27,4³ = 64We see that 30 is between 27 and 64 and is closer to 27:
27 < 30 < 64Therefore cube root of these numbers are:
∛27 < ∛30 < ∛643 < ∛30 < 4So the ∛30 is between 3 and 4 and closer to 3.
Correct answer choice is A.
Answer:
A) Between 3 and 4, but closer to 3.
Step-by-step explanation:
A perfect cube is the result of multiplying the same integer three times.
First few perfect cubes: 1, 8, 27, 64, 125, etc.To estimate the value of the cube root of a number, find the perfect cubes above and below the number:
The perfect cubes either side of 30 are:
27 < 30 < 64Therefore, the cube roots are:
[tex]\implies \sf \sqrt[3]{27} < \sqrt[3]{30} < \sqrt[3]{64}[/tex]
[tex]\implies \sf 3 < \sqrt[3]{30} < 4[/tex]
As 30 is closer to 27 than 64, the cube root of 30 is closer to the cube root of 27 than the cube root of 64.
Therefore, the cube root of 30 would be plotted on a number line:

you rent a moving van you have to pay a flat fee of $99 plus $0.50 per mile you drive 120 miles how much does it cost to drive the van also I NEED work
Answers
It cost $159 to drive the van for 120 miles
Explanation:
The flat fee of the van = $99
The charge per mile = $0.50
Let m represent the number of miles
T = total cost
The total cost becomes:
T = 0.5m + 99
When you drive 120 miles, m = 120 miles
T = 0.5(120) + 99
T = 60 + 99
T = $159
Hence, it cost $159 to drive the van for 120 miles
