Simplifying
3.57x + 1.61 = 4.71 + -2.63x
Reorder the terms:
1.61 + 3.57x = 4.71 + -2.63x
Solving
1.61 + 3.57x = 4.71 + -2.63x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2.63x' to each side of the equation.
1.61 + 3.57x + 2.63x = 4.71 + -2.63x + 2.63x
Combine like terms: 3.57x + 2.63x = 6.2x
1.61 + 6.2x = 4.71 + -2.63x + 2.63x
Combine like terms: -2.63x + 2.63x = 0.00
1.61 + 6.2x = 4.71 + 0.00
1.61 + 6.2x = 4.71
Add '-1.61' to each side of the equation.
1.61 + -1.61 + 6.2x = 4.71 + -1.61
Combine like terms: 1.61 + -1.61 = 0.00
0.00 + 6.2x = 4.71 + -1.61
6.2x = 4.71 + -1.61
Combine like terms: 4.71 + -1.61 = 3.1
6.2x = 3.1
Divide each side by '6.2'.
x = 0.5
Simplifying
x = 0.5

Answer:
Ten over two would be at the very right side of this number line. It would be located at the number 5. Negative nine over two would be located two segment or lines after negative five.
Step-by-step explanation:
Ten over two would come out to a positive and whole number of five. Negative nine over ten comes out so negative four wholes and one half. So this gets located two segments after negative five because it is not fully negative five but it is negative four and one half. I got these whole numbers by simplifying the numbers that we started off with. Hope you have an amazing day and do well on your assignments.

Answer:
(x, y, z) = (8√7/105, 2√7/21, 4√7/35)
Step-by-step explanation:
The algebra is straightforward, if tedious.
We'll define X = x^2, Y = y^2, Z = z^2, -1/16 = a, -1/25 = b, -1/36 = c. Then the equations become ...
√X = √(Y +a) +√(Z +a) . . . . [eq1]
√Y = √(Z +b) +√(X +b) . . . . [eq2]
√Z = √(X +c) +√(Y +c) . . . . [eq3]
__
As with any radical equation, you square both sides, isolate the remaining radical, then square both sides again. Each squaring introduces extraneous solutions.
The equations are symmetrical, so we can do the tedious stuff on the first one, then make the appropriate substitutions to see the other two equations.
X = Y +a + 2√((Y+a)(Z+a)) +Z +a
X - Y - Z -2a = 2√((Y+a)(Z+a)) . . . . isolate the remaining radical
(X -Y -Z -2a)^2 = 4(Y+a)(Z+a) . . . . square both sides again
X^2 +Y^2 +Z^2 +4a^2 -2XY -2XZ +2YZ -4aX +4aY +4aZ = 4YZ +4aY +4aZ +4a^2
Subtracting the right side gives ...
X^2 +Y^2 +Z^2 -2XY -2XZ -2YZ -4aX = 0 . . . . [eq4]
Then the remaining equations are ...
X^2 +Y^2 +Z^2 -2XY -2XZ -2YZ -4bY = 0 . . . . [eq5]
X^2 +Y^2 +Z^2 -2XY -2XZ -2YZ -4cZ = 0 . . . . [eq6]
Subtracting [eq6] from [eq5] gives a relation between Y and Z:
-4bY +4cZ = 0
Z = bY/c . . . . [eq7]
Substituting this into [eq4], we have ...
X^2 +Y^2 +(bY/c)^2 -2XY -2X(bY/c) -2Y(bY/c) -4aX = 0
X^2 +Y^2(1 -2b/c +(b/c)^2) -2XY(1 +b/c) -4aX = 0 . . . . [eq8]
Subtracting [eq5] from [eq4] gives a relation between X and Y:
-4aX +4bY = 0
Y = aX/b . . . . [eq9]
Substituting this into [eq8], we have ...
X^2 +(aX/b(1 -b/c))^2 -2X(aX/b)(1 +b/c) -4aX = 0
Dividing by X* gives a linear equation in X:
X(1 +(a/b(1 -b/c))^2 -2a/b(1+b/c)) -4a = 0
X = 4a/(1 +(a/b(1 -b/c))^2 -2a/b(1+b/c))
Substituting the above values for a, b, c, we have ...
X = 64/1575
x = √X = √(64/1575) = 8/(15√7)
Y = X(25/16)
y = x(5/4) = 2/(3√7)
Z = Y(36/25)
z = y(6/5) = 4/(5√7)
The solution is ...
x = 8√7/105 ≈ 0.201581y = 2√7/21 ≈ 0.251976z = 4√7/35 ≈ 0.302372_____
* At this point the equation is of the form pX^2 +qX = 0 or X(pX +q) = 0. One solution is X=0, which is extraneous. The solution of interest is X = -q/p.

The water level in a reservoir is now 52 meters. If this was a 23% increase, what was the initial depth?
Answer:
40.04
Step-by-step explanation:
It was at 40.04 before the 23% increase. To find 23 % of 52 set it up as a inequality.
x/52 = 23/100
Cross multiply
52 * 23 = 1,196 100 * x =100x
Now solve for x.
100x /100 = 1,196/100 x = 11.96
Subtract answer from 52 to get answer
52 - 11.96 = 40.04

A computer store buys a computer system at a cost of $572.40. The selling price was first at $954, but then the store advertised a 20% markdown on the system. Answer parts a and b.
Answer:
The sale price is $763.20
The price for club members is $610.56
The current selling price is $763.20, and the cost to members with an additional 10% reduced rate is $686.88.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of one hundred. And the sign for it is "%."
Given, a computer store buys a computer system at a cost of $572.40.
And the selling price was first at $954, but then the store advertised a 20% markdown on the system.
To find the current sale price:
Current sales price;
use percentage formula,
= $954 - (20% × $954)
= $954 - (0.2 × $954)
= $954 - $190.80
= $763.20
To find the cost to club members at 10% additional reduced price:
use percentage formula,
= $763.20 - (10% × $763.20)
= $763.20 - (0.1 × $763.20)
= $763.20 - $76.32
= $686.88
Therefore, the current sale price is $763.20, and it will cost $686.88 to the members.

Step-by-step explanation:
47.9 is what percent of 152?
A)3.2%
B)31.5%
C)0.32%
D)317.3%
Answer: B
Step-by-step explanation:
Step 1: We make the assumption that 152 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100%=152
Step 4: In the same vein, x%=47.9
Step 5: This gives us a pair of simple equations:
100%=152(1).
x%=47.9(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 152/47.9
x= 31.5

Step-by-step explanation:
2/5+6/10
What is the answer
We have to make sure the denominators are equal.
10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.
Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10
Now the equation is 4/10 + 6/10
Since our denominators match, we can add the numerators.
4 + 6 = 10
That gives us the sum, which is 10/10 aka 1 whole
