Solve the systems of equation by graphing

Answer:

square root of 197

Step-by-step explanation:

Answer:  Let the 2 numbers be x and  

sum of two numbers is 28....Eq 1:  x + y = 28

sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2:  6x + 3y = 105

Rearrange Eq 1 to solve for x.

x + y = 28

x = 28 - y  --> Substitute into Eq 2, you get

6(28 - y) + 3y = 105

168 - 6y + 3y = 105

-3y = -63

y = -63 / -3 = 21

Now solve for x using Eq 1.

x = 28 - y = 28 - 21 = 7

Answer:

Width = 6

Length = 7

Step-by-step explanation:

Consecutive integers: x and x+1

2x + 2(x+1) = 26

2x +2x + 2 = 26

4x = 26 - 2

x = 24/4

x = 6

18. BANALITIES

Step-by-step explanation:

Answer:

D. 14 cents

Step-by-step explanation:

At 10 feet for $7, that is 70 cents for every foot

At 20 feet for $13, that is 65 cents for every foot

At 50 feet for $28, that is 56 cents for every foot

At 100 feet for $57.50, that is 58 cents (rounded) for every foot

The best deal is 50 feet at 56 cents

The worst deal is 10 feet at 70 cents

So we do 70 - 56 = 14

So the answer is the savings per unit between the best deal and worst deal is 14 cents

Answer:

n = 3.16 units; p = 5 units

Step-by-step explanation:

to find the length of the lines you need to use the pythagorean  theorem or a^2 + b^2 = c^2

in this case a is x, b is y, and c is the length

so for n it is:

1^2 + 3^2 = c^2 -->

1 + 9 = c^2 -->

10 = c^2

c = 3.16227766 or about 3.16 (this is n's length)

for p it is:

3^2 + 4^2 = c^2 -->

9 + 16 = c^2 -->

25 = c^2 -->

c = 5 (this is p's length)

Answer:

v=-1

Step-by-Step Explanation:

Answer:

[tex]v=-1[/tex]

Step-by-step explanation:

[tex]6\left(6v+6\right)-5=1+6v[/tex]

Use the distributive property to multiply 6 by 6v+6:

[tex]36v+36-5=1+6v[/tex]

Subtract 5 from 36 = 31

[tex]36v+31=1+6v[/tex]

Subtract 6v from both sides:

[tex]36v+31-6v=1[/tex]

Combine like terms:

[tex]36v[/tex] and [tex]-6v[/tex] [tex]=30v[/tex]

[tex]30v+31=1[/tex]

Subtract 31 from both sides:

[tex]30v=-30[/tex]

Divide both sides by 30:

[tex]\cfrac{30v}{30}=\cfrac{-30}{30}[/tex]

[tex]v=-1[/tex]

Step-by-step explanation:

Answer:

[tex]x > 7 \div \frac{1}{2} [/tex]

[tex]x > 7 \times 2[/tex]

[tex]x > 14[/tex]

Answer:

x = 32

Step-by-step explanation:

The angle above 72° is 108° because they are supplementary angles, meaning they add up to 180°. Then we can set the equation 108° = (3x + 12)° because they are alternate interior angles, meaning that they are the same. So then we just solve for x.

108 = (3x + 12)

108 - 12 = 3x

96 = 3x

96 / 3 = x

32 = x

Answer:

j = 7

Step-by-step explanation:

First expand the right hand side:

3 = 3(j-6)

3 = 3j - 18

Then we can move 18 to the left hand side and calculate for j.

3 = 3j - 18

21 = 3j

j = 7

3500

Step-by-step explanation:

To find a fraction of something just keep in mind that "of" means to multiply (when dealing with fractions and percents).  In this case we want to know what 5/6 of 4200 is.  So do (5/6)*4200 and that equal 3500.
