Can someone solve this?
Answer:
Y=-5.6
x=.9
Step-by-step explanation:
Isolate the x:
6x=11+y
2x=7-3y
multiply top by 3 to get rid of y(3y and -3y cancel each other out)
18x=11
2x=7
put them together:
20x=18
divide by 20
x=0.9
to find y plug in x to the first equation:
y=6(.9)-11
y=5.4-11
y=-5.6
I hope this is right, and that it helps!

One of the roots of equation x^(2)-(3p-4)x+11p-5=0 is 8. Find the other root. Find the value of p.
Answer:
other root: x = 9
p = 7
Step-by-step explanation:
first, find p:
(8)² - (3p - 4)8 + 11p -5 = 0
64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0
91 - 13p = 0
-13p = -91
p = 7
plug in p to find the polynomial:
x² - (3(7) - 4)x + 11(7) - 5 = 0
x² - (21 - 4)x + 77 - 5 = 0
x² - 17x + 72
find the roots:
we know that 8 is one of the roots, so one factor is (x - 8)
the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8
that number is -9
so the poly nomial factors to be: (x-8)(x-9)
so the roots are x = 8 and x = 9
Answer:
p = 7
Step-by-step explanation:
x²-(3p-4)x+11p-5=0 ...(1) Root: 8, x-8 is factor
(x-8) (x- (11p-5)/8) = 0
x² -8x - ((11p-5)/8)*x + (11p-5) = 0
x² - (8 + (11p-5)/8) x + 11p-5 = 0 ----(2)
compare(1) and (2): 3p-4 = 8 + (11p-5)/8
24p - 32 = 64 + 11p - 5
13p = 91
p = 7
check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

The runner covers a 100 meters in 9.7 seconds. What is her speed?
sentence answers only please?
Answer:
10.3 m/s
Step-by-step explanation:
Speed = Distance / Time
100 metres travelled in 9.7 seconds means that her speed was 100/9.7 metres per second, which is 10.30927... rounded to 10.3 metres per second.

HELp pleaase ;Bbbbbbb
Answer:
the answer for this one is B
Answer:
The answer would be B.
Step-by-step explanation:
Just substitute x for 5.
For example, A is 2+x=3.
Just put 5 instead of x.
It would be 2+5=3.
But that isn't the answer because 2+5 is 7, not 3.
For B, sub the x for 5 just like we did for A.
It would usually be 3x=15
But sub the x with 5.
It would turn into 3x5=15
And that is right, because if you multiple 5 three times, it would be 15.

Answer:
The length and breadth of the fence are 80 and 70 meters, respectively.
Step-by-step explanation:
Let suppose that fencing has a rectangular form. The length to breadth ratio is [tex]\frac{8}{7}[/tex]. Dimensionally speaking, the total cost for fencing the plot ([tex]C[/tex]), measured in monetary units, is the product of perimeter of the rectangle ([tex]p[/tex]), measured in meters, and unit cost ([tex]c[/tex]), measured in monetary units per meter, that is:
[tex]C = c\cdot p[/tex] (1)
[tex]C = 2\cdot c\cdot (w+l)[/tex] (2)
Where:
[tex]w[/tex] - Breadth of the fence, measured in meters.
[tex]l[/tex] - Length of the fence, measured in meters.
By applying the ratio described above, we reduce (2) into this form:
[tex]C = 2\cdot c\cdot \left(\frac{1}{r} +1\right)\cdot l[/tex] (3)
Where [tex]r[/tex] is the length to breadth ratio, no unit.
If we know that [tex]C = 60000[/tex], [tex]c = 200[/tex] and [tex]r = \frac{8}{7}[/tex], then the length and breadth of the rectangle are, respectively:
[tex]l = \frac{C}{2\cdot c\cdot \left(\frac{1}{r} +1\right)}[/tex]
[tex]l = \frac{60000}{2\cdot (200)\cdot \left(\frac{7}{8}+1 \right)}[/tex]
[tex]l = 80\,m[/tex]
[tex]w = \frac{l}{r}[/tex]
[tex]w = \frac{80\,m}{\frac{8}{7} }[/tex]
[tex]w = 70\,m[/tex]
The length and breadth of the fence are 80 and 70 meters, respectively.

Courtney has $4.85 in nickels, quarters, and dimes. She has12 quarters and 7 nickels. How many more dimes than nickels does she have?
A. 8
B. 12
C. 15
D. 30
Answer:
8 dimes
Step-by-step explanation:
A quarter is $0.25, so 0.25 should be multiplied by the number of quarters she has:
0.25 * 12 = 3.00
A nickel is $0.05, so 0.05 should be multiplied by the number of nickels she has:
0.05 * 7 = 0.35
If we add this together, we get 3.35, and the rest of the money Courtney has is in dimes. First, find the amount of money left:
4.85 - 3.35 = 1.50
A dime is $0.10, so divide the amount of money left by 0.10 to find the number of dimes Courtney has:
1.50 ÷ 0.10 = 15
Subtract 15 by the number of nickels Courtney has to find how many more dimes she has than nickels:
15 - 7 = 8 dimes

Math page 340 what number would you multiply the dividend and divisor by to make 5.72 divide 0.52 easier to divide?
Answer:
Multiply both the divisor and the dividend by 10 to make it easier to divide
Step-by-step explanation:
As given division equation in a more suitable format that shows the dividend and the divisor that is = [tex]\frac{5.72}{0.52}[/tex]
so now we we will make the two parts to be whole number
first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places
so, that we multiplying both of them by a 10 will make them whole numbers
so so correct answer is 10
[tex]\frac{5.72\times 10}{0.52 \times 10} =[/tex] 11
Find the location of the point given the rule.
Answer:
see explanation
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ). then
G(3, 4 ) → G'(3, - 4 )
Q(4, - 1 ) → Q'(4, 1 )
L(1, 2 ) → L'(1, - 2 )
The total perimeter of the fence is 68 ft and the area is 240 square feet. Based on this information, what are the dimensions of the fence?
Answer:
6ft by 40ft
Step-by-step explanation:
Perimeter = 2(L+W)
Area = LW
L is the length of the fence
W is the width
Given
P = 68ft
A = 240ft²
Substitute into the formula
68 = 2L+2W ... 1
240 = LW... 2
From 1;
34 = L+W
L = 34-W ... 3
Substitute 3 into 2
From 2;
LW = 240
(34-W)W = 240
34W - W² = 240
- W²+34W = 240
W²-34W - 240 = 0
W²+6W-40W - 240 = 0
W(W+6)-40(W+6) = 0
W-40 = 0
W = 40feet
Since
34 = L+W
34 = L + 34
L = 6ft
Hence the dimension of the fence is 6ft by 40ft

The complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Rearranging the equation x² - 51 = 14
x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10
x = 7 - 10
x = -3
Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.
