A student is trying to solve the system of two equations given below:
Equation P: y + z = 6
Equation Q: 3y + 4z = 1
Which of the following is a possible step used in eliminating the y-term?
a. (y + z = 6) ⋅ 4
b. (3y + 4z = 1) ⋅ 4
c. (y + z = 6) ⋅ −3
d. (3y + 4z = 1) ⋅ 3
Answer:
c. (y + z = 6) ⋅ −3
Step-by-step explanation:
We want to use elimination to eliminate y in a system of equations
y + z = 6
3y + 4z = 1
We can take the first equation and multiply by -3 to make the y term -3 so when we add the equations -3y + 3y =0
-3(y + z = 6)
3y + 4z = 1
--------------------
-3y -3z = -18
3y + 4z = 1
---------------------
0y +z = -17
Answer:
c. (y + z = 6) ⋅ -3
Explanation:
Equation P : y + z = 6
Equation Q : 3y + 4z = 1
In order to solve by elimination and remove the y-term, the coefficients of y must be same or negative to each other in both the equations.
So to make the y co-efficient similar here, multiply the first equation by -3
When done: (y + z = 6) · -3 = -3y - z = -18
Solving steps:
-3y - 3z = -18
3y + 4z = 1
------------------
z = -17
There the y-term has been removed.

Answer:
500 cm³
Step-by-step explanation:
Using the given values in the given formula, we find the volume to be ...
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3)(5\text{ cm})^3 = 4(125\text{ cm}^3) = \boxed{500\text{ cm}^3}[/tex]
The volume of the sphere is about 500 cubic centimeters.
_____
Additional comment
The actual value of pi would add about 4.72% to this figure, bringing the estimate to about 523.6 cm³.
Step-by-step explanation:
Step 1: Formula
Solve for: Volume
Formula: V=4/3 πr^3
Explanation in words (Short Form)
- The first step is to use the formula and simplify it. So first we will use the formula which is V = 4/3 π and then divide it by 3, 3 times.
- The second step is to solve and at the end the answer will result as 523.59. Here is the full explanation and how I solved it.
V = 4/3 π r³ = 4/3 × π × 5³ = 523.59878
Answer:
V≈523.6
Full Answer: 523.59878 OR 500

[tex]\int\limits_ } \, \frac{9x+2}{x^2+x-6} dx[/tex]
- Do not copy and paste --> Results in immediate reports (Point-seekers)
- Do not spam
- Do not add any unnecessary information
- Add an explanation
- Please help, thank you
Split the integrand into partial fractions.
[tex]\dfrac{9x+2}{x^2+x-6} = \dfrac{9x+2}{(x-2)(x+3)} = \dfrac a{x-2} + \dfrac b{x+3}[/tex]
[tex]\implies 9x+2 = a(x+3) + b(x-2) = (a+b)x + (3a-2b)[/tex]
[tex]\implies \begin{cases}a+b=9 \\ 3a-2b=2\end{cases} \implies a=4,b=5[/tex]
Then we have
[tex]\displaystyle \int \frac{9x+2}{x^2+x-6} \, dx = 4 \int \frac{dx}{x-2} + 5 \int \frac{dx}{x+3} \\\\ = \boxed{4\ln|x-2| + 5\ln|x+3| + C}[/tex]
which follows from the result
[tex]\displaystyle \int \frac{dx}x = \ln|x|+C[/tex]

Answer:
30%
Step-by-step explanation:
To express percentage as a fraction, the denominator must be 100.
Given ,
[tex]\frac{18/60}{60/60}\\= \frac{0.3}{1} \\= 0.3 * 100\\= 30%[/tex]
Answer:
1) Percent of skateboards that are longboards is 18÷60 or 30%
2) Number needed for equivalent ratio is 30 longboards
Step-by-step explanation:
1) Percentage= part divided by whole
18÷60 = 0.3
0.3 = 30%
2) Create a proportion, let x = # longboards needed for a equivalent ratio
(18÷60)=(x÷100)
x=30

Matthew visited the fruits garden last weekend and helped farmers count the fruits. There were 10% more dragon fruits than passion fruits. When 75 fruits were added, the dragon fruits were increased by 60% and the passion fruits increased by 9%. How many fruits were there at first?
Answer:
Step-by-step explanation:
let number of passion fruits=x
number of dragon fruits=x+10% of x
=x+0.1 x=(1+0.1)x=1.1 x
total number of fruits=x+1.1 x=(1+1.1)x=2.1 x
1.1x+60% of 1.1x+x+9% of x=2.1x+75
1.1 x+0.6 of 1.1 x+x+0.09 of x=2.1x+75
1.1x+0.66 x+x+0.09 of x =2.1x+75
2.1 x+0.75x-2.1 x=75
0.75 x=75
[tex]\frac{75}{100}x =75\\x=75 \times \frac{100}{75} =100\\Originally ~total ~number~ of~ fruits=2.1x=2.1 \times100=210[/tex]
Answer:
Step-by-step explanation:
let number of passion fruits=xnumber of dragon fruits=x+10% of x=x+0.1 x=(1+0.1)x=1.1 xtotal number of fruits=x+1.1 x=(1+1.1)x=2.1 x1.1x+60% of 1.1x+x+9% of x=2.1x+751.1 x+0.6 of 1.1 x+x+0.09 of x=2.1x+751.1x+0.66 x+x+0.09 of x =2.1x+752.1 x+0.75x-2.1 x=750.75 x=75

We want to figure out the 415th digit of this repeating decimal.
[tex] \dfrac{2}{7} = 0. \overline{285714}[/tex]
Obviously it's almost impossible and absurd to find the answer by writing down all the 415 digits. So instead we're going to use some tricks to do so.
Finding the 415th digit:There're 6 repeating digits. dividing 415 by 6 yields 69.17. Now multiplying 69 by 6 yields 414 which means that the 414th digit of the repeating decimal would be the last digit of the repeating digits, that is,4 and hence The 415th digit of the repeating decimal is gonna be 2. Hence the answer is B

Answer:
seventeen (17),nineteen (19),and twenty three(23)Which equations have a greater unit rate than the rate represented in the table? x y 3 2 6 4 9 6
Answer:
Any equation with a slope greater than ²/₃
Step-by-step explanation:
Given table:
[tex]\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} 3 & 2 \\\cline{1-2} 6 & 4 \\\cline{1-2} 9 & 6 \\\cline{1-2} \end{array}[/tex]
The unit rate is a ratio that compares the first quantity to one unit of the second quantity. The unit rate is also the slope of a linear equation.
Linear equation
[tex]y = mx + b[/tex]
where:
m is the slopeb is the y-interceptTo find the slope, take two ordered pairs from the table:
[tex]\sf let \: (x_1,y_1)=(3,2)[/tex]
[tex]\sf let \: (x_2,y_2)=(6,4)[/tex]
Substitute them into the slope equation:
[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-2}{6-3}=\dfrac{2}{3}[/tex]
Therefore, the unit rate is ²/₃.
Any equation with a slope greater than ²/₃ is an equation with a greater unit rate than that represented in the given table.
Slope of table
(3,2)(6,4)Slope
m=4-2/6-3m=2/3Any equation having slope greater than 2/3 has higher unit rate than that of table
A school has 4 different after-school activities planned in the fall. Janet has time to participate in 2 of these activities. How many different pairs of after-school activities can Janet choose from the available activities?
Answer:
6
Step-by-step explanation:
Think of the activities as numbers 1, 2, 3, 4. Since she can only do two, here are all the combinations: 1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, 3 and 4.
That is 6 different combinations in total.
