Answer:
it will take 1/5 of a day for Amir to catch up to Jesse
Step-by-step explanation:
30x = 35x - 1
30x - 35x = - 1
-5x = -1
-5x/-5 = -1/-5
x = 1/5
Answer: brainliest pls
1. y = 35x
2. y = 30x + 1
3. y = 35x
y = 30 x + 1
4. Its more convenient to substitute y because It's easier.
35x = 30(x + 1)
5. 35x = 30x + 1
35x = 30x + 30
35x -30x = 30
5x = 30
x = 6 (30/5 = 6)
35 x 6 = 210 (y)
6. Both people have read 210 pages and it takes amir 6 days to catch up.

Answer:
Step-by-step explanation:
since the first equation is already simplifies to y = 2x plug in 2x for the y in the second equation and solve
x = -(2x) + 6
x = -2x + 6
3x = 6
x = 2
plug in our x to the original equation
y = 2(2)
y = 4
so our answer is (2,4)
hope this helps <3
Answer:
x = 2
Step-by-step explanation:
If y is 2x, and x is -y + 6, what's x?
So let's use substitution method. Just replace the -y in x = -y + 6 with 2x:
x = -y + 6
x = -2x + 6
add 2x to both sides
3x = 6
divide by 3
x = 2
Use the Divergence Theorem to calculate the surface integral
S
F · dS;
that is, calculate the flux of F across S.
F(x, y, z) = x2yi + xy2j + 3xyzk,
S is the surface of the tetrahedron bounded by the planes x = 0, y = 0, z = 0, and
x + 4y + z = 4.
Answer:
[tex]\frac{56}{15}[/tex]
Step-by-step explanation:
Given that [tex]\vec F(x, y, z) = x^2y \hat i + xy^2 \hat j + 3xyz \hat k[/tex]
F(x, y, z) = x^2y \hat i + xy^2 \hat j + 3xyz \hat k
The flux of \vec F across the surface S is given by
[tex]\int \int _s \vec F \cdot dS[/tex]
Where the survare S is the surface of the tetrahedron bounded by the planes x = 0, y = 0, z = 0, and x + 4y + z = 4.
Now, by using the Gauss Divergence theorem:
[tex]\int \int _s \vec{F} \cdot dS=\int \int \int _v \bigtriangledown \cdot \vec F dV[/tex]...(i)
where V is the volume enclosed by the surface S and [tex]dV=dxdydz[/tex]
\bigtriangledown \cdot \vec F = \hat i \frac {\partial \vec F}{\partial x}+\hat j \frac {\partial \vec F}{\partial y}+\hat k \frac {\partial \vec F}{\partial z}
=2xy+2xy+3xy=7xy
Putting this value in equation (i), we have
\int \int \int _v \bigtriangledown \cdot \vec F dV = \int \int \int _v (7xy)dxdydz
= [tex]7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y} \left( \int_{z=0}^{z=4-x-4y}xy\;dz\right)dxdy[/tex]
[tex]=7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y} xy(4-x-4y-0)dxdy \\\\=7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y}(4xy-x^2y-4xy^2)dxdy \\\\=7\int_{y=0}^{y=1} (2x^2y-\frac 1 3 x^3y-2 x^2y^2)|_{x=0}^{x=4-4y}dy \\\\[/tex]
[tex]=7\int_{y=0}^{y=1} (2(4-4y)^2y-\frac 1 3 (4-4y)^3y-2 (4-4y)^2y^2)dy[/tex]
[tex]=7\int_{y=0}^{y=1} (32(1-y)^2y-\frac {64}{3} (1-y)^3y-32(1-y)^2y^2)dy[/tex]
[tex]=7\int_{y=0}^{y=1} (32(1-2y+y^2)y-\frac {64}{3} (1-y^3-3y+3y^2)y-32(1-2y+y^2)y^2)dy[/tex]
[tex]=7\int_{y=0}^{y=1} \{32(y-2y^2+y^3)-\frac {64}{3} (y-y^4-3y^2+3y^3)-32(y^2-2y^3+y^4)\}dy[/tex]
[tex]=7 \{32(\frac 1 2 y^2- \frac 2 3 y^3+\frac 1 4 y^3)-\frac {64}{3} (\frac 1 2 y^2-\frac 1 5 y^5-y^3+\frac 3 4 y^4)-32(\frac 1 3 y^3-\frac 1 2 y^4+\frac 1 5 y^5)\} |_{y=0}^{y=1}[/tex]
[tex]=7 \{32(\frac 1 2 - \frac 2 3 +\frac 1 4 )-\frac {64}{3} (\frac 1 2 -\frac 1 5 -1+\frac 3 4 )-32(\frac 1 3 -\frac 1 2 +\frac 1 5 )\}[/tex]
[tex]=7\times \frac {8}{15} \\\\=\frac{56}{15}[/tex]
Hence, the flux of F across S is [tex]\frac{56}{15}[/tex].

Find the formula for an exponential function that passes through the two points given. (x, y) = (0, 4) and (x, y) = (3, 32)
Given:
The exponential function passes through two points (0,4) and (3,32).
To find:
The formula for the exponential function.
Solution:
The general form of an exponential function is
[tex]y=ab^x[/tex] ...(i)
where, a is initial value and b is growth factor.
The exponential function passes through two points (0,4) and (3,32). It means the function must be satisfy by these points.
Putting x=0 and y=4 in (i), we get
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
Putting a=4, x=3 and y=32 in (ii), we get
[tex]32=4b^3[/tex]
Divide both sides by 4.
[tex]8=b^3[/tex]
Taking cube root on both sides.
[tex]2=b[/tex]
Putting a=4 and b=2 in (i), we get
[tex]y=4(2)^x[/tex]
Therefore, the required formula for the exponential function is [tex]y=4(2)^x[/tex].

Pedro bought two cars, one for ₱600,000.00 and the other for ₱400,000.00. He sold the former at a gain of 10% and the latter at a loss of 12%. What percentage of the total investment was his gain or loss?
Answer:
Pedro had a gain of 1.2%
Step-by-step explanation:
Percentages
Pedro bought two cars. One for $600,000 and the other for $400,000.
He sold the first car at a 10% profit. Thus the gain was:
$600,000 * 10 / 100 = $60,000
He sold the other car at a 12% loss. Thus the loss was:
$400,000 * 12 / 100 = $48,000
The total gain or loss was $60,000 - $48,000 = $12,000
Since it's positive, the total balance is at gain.
The total investment was $600,000 + $400,000 = $1,000,000
The total gain is a percentage of the total investment of:
$12,000 / $1,000,000 * 100 = 1.2%
Pedro had a gain of 1.2%

Step-by-step explanation:
Heya! Considering that the question has already given you the values of x and y, all you are left to do is plug them back into the equation. The value of 6 multiplied by x- 5- gets you to 30. Since y is equal to 1, 3 multiplied by 1 gets you 3. 30-3 gets you to 27, so that is your answer. I hope this helped! (Please mark as branliest if I did happen to get this right. <3)

Answer:
[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]
Step-by-step explanation:
Given
Stores and Parking Lots
Required
Determine the area as a sum of area of stores and area of parking lots
First, calculate the area of the stores
The dimension of store A is: 25 by 10
The dimension of store B is: 25 by w
The dimension of stores A and B (as an entity) is: 25 by 10 + w
The area is then calculated as:
[tex]Area = 25 * (10 + w)[/tex] -------- A1
Next, calculate the area of the parking lots
The dimension of parking lot A is: 13.5 by 10
The dimension of parking lot B is: 13.5 by w
The dimension of parking lots A and B (as an entity) is: 13.5 by 10 + w
The area is then calculated as:
[tex]Area = 13.5 * (10 + w)[/tex] -------- A2
The area of the shopping center is then calculated as:
[tex]Area = A_1 + A_2[/tex]
[tex]Area = 25*(10 + w) + 13.5(10 + w)[/tex]

Ramon earns $1,625 each month and pays $53.80 on electricity. To the nearest tenth of a percent, what
percent of Ramon's earnings are spent on electricity each month?
Ramon spends
% of his earnings on electricity each month.
Answer:
3.1%
Step-by-step explanation:
53.80/1625 x 100 is 3.1
Hope this helps plz hit the crown ;D
So what you can do is divide 53.10 by 1735 to get percentage
0.0306051873 is your decimal, so move it right 2 places to get
3.06% of his money.
You asked for the nearest 10th of a percent, so you round that to
3.1%
Which equations could you solve using the addition property of equality? Check all that apply.
4+ y = 100
y -4 = 100
4y = 100 4 + 100=y
100 = y - 5
Answer:
4 + y = 96 = 100
y = 104 - 4 = 100
4 y = 25 = 100 4 + 100 = y = 104
100 = y = 105 - 5
Step-by-step explanation:
Plz mark me as brainliest have a good day
The equations could you solve using the addition property of equality is
y- 4 = 100.
We have to apply the property of addition equality
Now,
4 + y = 100
y= 96
and, y -4 = 100
y = 104
and, 4 y = 100
y= 25
and, 100 = y - 5
y= 105
Thus, the required equality is y- 4 = 100.
