-3+6x=25-8x solve for x

Answer:

he would need 11 quarters.

Step-by-step explanation:

you already have 3 dimes which is $0.30 and 11 quarters is $2.75.

Answer:

1. Subtract 18 from both sides to get the equation set to 0:

x2 + 7x - 18 = 0

Now factor. Given the negative sign in front of the 18, you will have (x + ) (x - ) as your factors, with the larger one being positive. Now, which factors of 18 can be combined to get a result of 7? I'll leave that for you.

2- 2.3 Solve : p-7 = 0

Add 7 to both sides of the equation :

p = 7

3-Final result :

(m - 1) • (m - 8)

Trying to factor by splitting the middle term

1.1 Factoring x2-16x+63

The first term is, x2 its coefficient is 1 .

The middle term is, -16x its coefficient is -16 .

The last term, "the constant", is +63

Step-1 : Multiply the coefficient of the first term by the constant 1 • 63 = 63

Step-2 : Find two factors of 63 whose sum equals the coefficient of the middle term, which is -16 .

-63 + -1 = -64

-21 + -3 = -24

-9 + -7 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -7

x2 - 9x - 7x - 63

Answer:

x = 10.6 units

Step-by-step explanation:

We can use sine to solve this since sine is opposite over hypotnuse.

sin(62) = x/12

.883 = x/12

x = .883 * 12

x = 10.6

Answer:

(7,12),(-12,-7)

Step-by-step explanation:

x^2 + y^2 = 193

x - y = - 5

x = y - 5

(y - 5)^2 + y^2 = 193

y^2 - 10y + 25 + y^2 = 193

2y^2 - 10y + 25 = 193

2y^2 - 10y + 25 - 193 = 0

2y^2 - 10y - 168 = 0

2*(y^2 - 5y - 84) = 0     This factors into

2*( y - 12) (y + 7) = 0

y = 12    

in which case x = 12 - 5 = 7

y = - 7

in which case x = -7 - 5 = - 12

Answer:

The solution is [tex]x = \frac{39}{4}[/tex]

Step-by-step explanation:

We are given the following equation:

8x - 61 = 17

We want to find the solution, that is, the value of x. So

[tex]8x - 61 = 17[/tex]

[tex]8x = 78[/tex]

[tex]x = \frac{78}{8}[/tex]

Simplifying by 2

[tex]x = \frac{39}{4}[/tex]

The solution is [tex]x = \frac{39}{4}[/tex]

Answer/Step-by-step explanation:

8. m<DEF = 122°

m<FEG + m<DEF = 180° (Angles on a straight line)

m<FEG + 122 = 180 (Substitution)

m<FEG = 180 - 122

m<FEG = 58°

9. m<BOC = 27°

m<AOC = 47°

m<AOB + m<BOC = m<AOC (angle addition postulate)

m<AOB + 27 = 47 (substitution)

m<AOB = 47 - 27 (Subtraction property of equality)

m<AOB = 20°

Answer:D

Step-by-step explanation:its the same thing but the numbers are flipped, you get the same answer either way.

The statement that illustrates the commutative property of addition is

8i + 4 = 4 + 8i. The correct option is D.

The commutative property of addition:

Let a and b are numbers.

a + b =  b + a

The change in the position of two numbers in an addition operation does not change the sum.

The commutative property of addition:

Let a and b are numbers.

So, a + b =  b + a.

LHS = 8i + 4

= 2 (4i+2)

= 2(2 + 4i)

=  4 + 8i

That means,  8i + 4 = 4 + 8i holds the commutative property of addition.

Therefore, the equation is 8i + 4 = 4 + 8i.

Answer:

Step-by-step explanation:

Answer:

i. 6 feet by 3 feet

ii. 7 feet by 2 feet

iii. 8 feet by 1 feet

Step-by-step explanation:

From the given question, we have;

length of the rectangular fence, l = 6 feet

perimeter of the rectangular fence = 18 feet

Let the width of the rectangular fence be represented by w.

So that,

Perimeter of a rectangle= 2(length + width)

18 = 2(6 + w)

18 = 12 + 2w

18 - 12 = 2w

6 = 2w

w = [tex]\frac{6}{2}[/tex]

w = 3

The width of the rectangular fence would be 3 feet when the length is 6 feet.

Thus, the possible dimensions of the rectangular fence are:

i. 6 feet by 3 feet

ii. 7 feet by 2 feet

iii. 8 feet by 1 feet

Answer:1 black 4 white

Step-by-step explanation:

It must be 2:3 so you have to change the current ratio from black to white(7:8) to 2:3

So the first number has to be the closets multiple of 2(8) and you have to divide 8 by 2 to get 4 and multiply that by 3 to get the ratio 8:12 which is equivalent to 2:3
