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.

I hope this helps, I did my best. Have a great day!

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

Step-by-step explanation:

Factor out a 1/2

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

Answer:

2 , -4 , (2,0)

Step-by-step explanation:

The slope of the linear function is 2.

The y-intercept of the linear function is -4.

The solutions of the linear function are (0, -4), (1, -2), (2, 0), etc..

The graph is given below.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The linear function is y = mx + c

The linear function passes through (-2, -8) and (1, -2)

Now,

m = (-2 + 8) / (1 + 2)

m = 6/3

m = 2

The slope of the linear function is 2.

Now,

(-2, -8) = (x, y)

-8 = 2 x (-2) + c

-8 = - 4 + c

c = -8 + 4

c = -4

The y-intercept is -4.

The equation of the linear function.

y = 2x - 4

The solution of the line are (0, -4), (1, -2), (2, 0), etc..

When x = 0,

y = -4

When x = 1,

y = -2

When x = 2,

y = 0

Now,

The graph of the line is given below.

Thus,

The slope is 2.

The y-intercept is -4.

The solutions are (0, -4), (1, -2), (2, 0), etc..

Answer:

3

Step-by-step explanation:

as the hour goes up one the temperature rises by 3

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)

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

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

Answer:

Because it will take a lot of time to do

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.

Answer: $1,780

Step-by-step explanation:

Joy Wigens deposited 1/3 of the check of $2,670 that she received in her Citibank account.

The amount she deposited in her Citibank account was:

= 1/3 * 2,670

= $890

The amount she is left with after this deposit will therefore be:

= Check amount - deposit at Citibank

= 2,670 - 890

= $1,780
