Answer:x = -1 / 12

Step-by-step explanation: am i right??

8x + 8y = 2 -------(1)

8x + 5y = 1 -------(2)

subtract equation (2) from equation (1)

The 8x will be eliminated, leaving us with;

3y = 1

Divide bothside of the equation by 3

y = 1/3

substituting y = 1/3 in equation (1)

8x + 8y = 2

8x + 8(1/3) = 2

8x + 8/3 = 2

subtract 8/3 from both-side

8x + 8/3 -8/3 = 2 -8/3

8x = 2 - 8/3

8x = 6 - 8 / 3

8x = - 2/3

Divide both-side of the equation by 8

8x / 8 = -2/3 ÷ 8

x = -2/3 × 1/8

x = -1 / 12

Answer:

30 feet

Step-by-step explanation:

There a 3 ft in a yard

If there's 10 yards

then multiply 10 x 3 to get 30 feet

Step-by-step explanation:

they have the same constant rate of change

Answer:

if its a parabola on a grahp grab two points x and y and divide y/x and the answer that you get is the slope if you dont know what x and y are it is basically X is a number from the line that goes straight across on a line you can memorize it by running and y is the one that is upwards you can memoriza that by jumping im triying my best to explain sorry if doesnt make sense

Answer:

chemistry textbooks:177

physics textbooks:237

Step-by-step explanation:

414-60=354

354/2=177

177+60=237

Answer:

350

Step-by-step explanation:

so the first step is to find the values of each of them

7x10^6=7000000

2x10^4=20000

then we divide 7000000 by 20000

7000000/20000=350

so the answer is 350

hope this helps :)

Answer:

[tex]\frac{3}{16}[/tex]

[tex]4\frac{2}{11}[/tex]

[tex]\sqrt{5}[/tex]

Step-by-step explanation:

[tex]\sqrt{5}=2.2360679...\\\\\frac{3}{16}=0.1875\\\\4\frac{2}{11}= \frac{46}{11}=4.18181818...[/tex]

The decimal forms of some real numbers, like [tex]\frac{3}{16}[/tex], terminate, while the decimal forms of other real numbers, like [tex]4\frac{2}{11}[/tex], do not terminate, but have a repeating pattern. Still other real numbers, like [tex]\sqrt{5}[/tex], have decimal forms that neither terminate nor repeat.

Answer:

8) Obtuse triangle

9) Right triangle

12) Equilateral triangle

Step-by-step explanation:

8)

x + 48 + 32 = 180

x + 80 = 180

x = 100

Answer: The walking path around it.

Step-by-step explanation:

Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:

A^2 + B^2 = H^2

or

H = √(A^2 + B^2)

Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge

Here we can see that:

A = 1170 ft

B = 520 ft

Then:

H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft

Now, let's compute the costs.

For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:

Cost of the bridge = (1280.4)*$11 = $14,084.4

And for the walking path, the cost is $6 per foot, then the total cost of the path is:

Cost of the path = (520 ft + 1170 ft)*$6 = $10,140

We know that the bridge is preferred if it is within the range of $1500 for the path's cost.

This range is:

($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)

Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

Answer:

a31 = -334

Step-by-step explanation:

Given:

a1 = 26

a22 = -226

Find:

a31

Computation:

a22 = a + 21d

-226 = 26 + 21d

d = -12

a31 = a + 30d

a31 = 26 + 30(-12)

a31 = 26 - 360

a31 = -334

a1 = 26 and a22 = −226.

Answer:

A)  −334

Answer:

Tan(O) = 4/3

Step-by-step explanation:

According to SOH CAH TOA

cos theta = adj/hyp

cosO = 3/4

adj = 3

hyp = 5

Get the opposite

Using pythagoras theorem

opp^2 = hyp^2-adj^2

opp^2 = 5^2 - 3^2

opp^2 = 25-9

opp^2 = 16

opp = 4

Tan (O) = opp/adj

Tan(O) = 4/3

Hence Tan(O) = 4/3

Answer: X = 30*

All circles = 360*

we can subtract 260 from that because we know the length of one so we know the other is 130.

We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50

Answer:

[tex]\frac{20}{13}[/tex] + [tex]\frac{5}{13}[/tex] [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5}{4-\sqrt{3} }[/tex]

To rationalise the denominator, multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of 4 - [tex]\sqrt{3}[/tex] is 4 + [tex]\sqrt{3}[/tex]

= [tex]\frac{5(4+\sqrt{3}) }{(4-\sqrt{3})(4+\sqrt{3}) }[/tex]

= [tex]\frac{20+5\sqrt{3} }{16-3}[/tex]

= [tex]\frac{20+5\sqrt{3} }{13}[/tex]

= [tex]\frac{20}{13}[/tex] + [tex]\frac{5}{13}[/tex] [tex]\sqrt{3}[/tex]

Answer: Yes, it'll be approved

Step-by-step explanation:

To solve this, we.need to calculate 2/9 of 78 states. This will be:

= 2/9 × 78

= 17 states

Since 21 states approve an​ amendment, then the constitution will be​ amended because the number of states is more than 2/9 of the 78 states
