Answer:
B
Step-by-step explanation:
The system of the equation that has only one solution is; 5x-4y=8 and 3x+2y=8.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We have to determine;
Which system of equations has only one solution
As per the question, a system of linear equations can have one solution if there is only one point that makes every equation in the system true. It implies that there is one point that can satisfy all of the equations at the same time.
The system of equations has only one solution is;
5x-4y=8
3x+2y=8
from equation 1
5x-4y=8
5x=8+4y
[tex]x=\frac{8+4y}{5}[/tex]
Putting the value of x in equation 2
3x+2y=8
[tex]3(\frac{8+4y}{5})+2y=8[/tex]
[tex](\frac{24+12y}{5})+2y=8[/tex]
24+12y+10y=[tex]5*8[/tex]
24+22y=40
22y=40-24
22y=16
y=[tex]\frac{16}{22}[/tex]
y=[tex]\frac{8}{11}[/tex]
Putting the value of b in equation 1,
3x+2y=8
3x+2[tex]\frac{8}{11}[/tex]=8
3x=8-[tex]\frac{16}{11}[/tex]
3x=[tex]\frac{88-6}{11}[/tex]
[tex]x=\frac{82}{33}[/tex]
Therefore, the system of equation which has exactly one solution are;
5x-4y=8 and 3x+2y=8.

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.

Use inductive reasoning to predict the next number in the pattern: 832, 208, 52...
A.) 13
B.) -228
C.) -26
D.) 26
Answer:
A) 13 i think
Step-by-step explanation:
832 , 208 , 52
The difference between 832 and 208 is 624 and then the difference between 208 and 52 is 156. If we check the relation between 624 and 156 which is 624/4 = 156 so then if we divide 156 by 4 we get 39 and then subtract 39 from 52 we get 13.
Answer:
13

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

Answer:
9
Step-by-step explanation:
. Solve the equation. -3/4 (x - 3) - 5 = 1/8 (x - 1) *
[tex] \frac{ - 3}{4} (x - 3) - 5 = \frac{1}{8} (x - 1)[/tex]
[tex] \frac{ - 3}{4} x + \frac{9}{4} - 5 = \frac{1}{8} x - \frac{1}{8} [/tex]
[tex] \frac{ - 3}{4} x - \frac{1}{8} x = - \frac{1}{8} - \frac{9}{4} + 5[/tex]
[tex] \frac{ - 6x}{8} - \frac{x}{8} = \frac{ - 1}{8} - \frac{18}{8} + \frac{40}{8} [/tex]
[tex] \frac{ - 6x - x}{8} = \frac{ - 1 - 18 + 40}{8} [/tex]
[tex] \frac{ - 7x}{8} = \frac{21}{8} [/tex]
[tex] - 7x = 21[/tex]
[tex]x = \frac{21}{ - 7} [/tex]
[tex]x = - 3[/tex]

Use the identity of the sum of two cubes to factor 8q6r3 + 27s6t3.
what is a?
what is b?
Answer:
Factors of [tex]8q^6r^3 + 27s^6t^3[/tex] are [tex](2q^2r+3s^2t)(4q^4r2-12q^2rs^2t+9s^4t^2)[/tex]
a is [tex]2q^2r[/tex]
b is: [tex]3s^2t[/tex]
Step-by-step explanation:
We need to factor [tex]8q^6r^3 + 27s^6t^3[/tex]
[tex]8q^6r^3 + 27s^6t^3\\=(2q^2r)^3+(3s^2t)^3\\Applying \ formula: a^3 + b^3 = (a + b)(a^2 - ab + b^2)\\=(2q^2r+3s^2t)((2q^2r)^2-2(2q^2r)(3s^2t)+(3s^2t)^2)\\=(2q^2r+3s^2t)(4q^4r2-12q^2rs^2t+9s^4t^2)[/tex]
So, Factors of [tex]8q^6r^3 + 27s^6t^3[/tex] are [tex](2q^2r+3s^2t)(4q^4r2-12q^2rs^2t+9s^4t^2)[/tex]
What is a? a is [tex]2q^2r[/tex]
What is b? b is: [tex]3s^2t[/tex]

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
your welcome :) (btw can u please give brainly?)
Answer:
2/5 + 6/10 = 1
Step-by-step explanation:
first let’s change 2/5 so it has the same denominator as 6/10.
2/5 * 2/2 = 4/10
now add
4/10 + 6/10 = 1

Step-by-step explanation:
Dustin's Lawn Care Service Customer Amount Paid Mrs. Schmitt $15.75 Mr. Jones $9.25 Mrs. Adams $22.50 Mr. Meyer $50.00 How much more does Dustin get paid to mow Mr. Meyer's lawn than to mow the other three lawns combined? Enter your answer in the box. I need helppppp!
Answer: $2.50
Step-by-step explanation:
The following payments are made by Dustin's Lawn Care Service Customer
Mrs. Schmitt = $15.75
Mr. Jones = $9.25
Mrs. Adams = $22.50
Mr. Meyer = $50.00
To get our answer, we need to add all the payments of the other three. This will be:
= $15.75 + $9.25 + $22.50
= $47.50
The answer will now be:
= $50.0 - $47.5
= $2.50

Answer:
tre made an error when adding or subtracting. the answer is 05
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
