Step-by-step explanation:

Answer:

208 4/25

Step-by-step explanation:

420 3/50-212 9/10

420 52/50 - 212 9/10

420-212:208

Combine

53/50-- 9/10 : 4/25

Answer 208 + 4/24

or just

208

Answer:

3rd option

Step-by-step explanation:

- 3.55g ≤ - 28.4

Divide both sides by - 3.55 , reversing the symbol as a result of dividing by a negative quantity

g ≥ 8

Since g is greater than or equal to 8 , then looking for a solid circle at g = 8 on the number line

Since g is greater than 8 then arrow pointing to the right from 8

This is shown on the third graph

Answer:

c is the correct answer

Step-by-step explanation:

Answer:

its 84 dollars sorry I'm late

Step-by-step explanation: Make a proportional relationship.

make 120% into a fraction. 120/100

then make 70 into a fraction using a variable. For example, x/70

Then cross multiply 120 and 70. 120x70=8,400

Last divide 8,400 by 100 and that equals $84.

Hope this helps!

Answer:

Since the above triangle is Iscocleles we can make our equation-

5x - 8 = 2x + 7

5x - 2x = 8 + 7

3x = 15

x = 5

Answer:

y = 1/3x

Step-by-step explanation:

Using the slope formula:

[tex]\frac{y2-y1}{x2-x1}[/tex]

Taking (-3,-1) as (x1,y1) and (6,2) as (x2,y2):

(2-(-1))/(6-(-3))

= (2+1)/(6+3)

= 3/9

= 1/3

Hence, the slope (m) is 1/3

Substituting the slope into 'y = mx+c':

y = 1/3x + c

Substituting any point, however, we will be substituting (-3,-1):

-1 = 1/3 * (-3) + c

-1 = -1 + c

c = -1 + 1

= 0

Hence,

y = 1/3x

Answer:

Width = 4

Length = 10

Step-by-step explanation:

Width: x

Length: x+6

2x + 2(x+6) = 28

2x + 2x + 12 = 28

4x = 28-12

x = 16/4

x = 4

Answer:

x = 4

Step-by-step explanation:

Volume of rectangular prism = Width * Length * Height

=> 180 = 3 * 5 * 3x

=> 180 = 45x

=> x = 180/45

∴ x = 4

Answer:

6.125 feet which as a fraction is 6 1/8

Step-by-step explanation:

Answer:

10/(1+√11),  1+√11 and 10/(1-√11) and  1-√11

Step-by-step explanation:

Let x be the first number and y the second number

two numbers that multiplied together give me 10

x*y = 10

and the difference of the two numbers is -2?

x-y = -2

we can write x in terms of y so we only have one variable y

x-y =-2 , add y to both sides

x-y+y = y -2, combine like terms

x= y-2

x*y = 10, substitute x=y-2

(y-2)y = 10, distribute in parenthesis

y² -2y-10 = 0, subtract 10 from both sides

We can use the quadratic formula to solve y² -2y-10 = 0

y = (-b±√b²-4ac)/2a, where a= 1, b= -2, c= -10

y = (2±√4+4*1*10)/2

y = (2±√44)/2

y= (2±2√11)/2

y= 1±√11

x*y = 10, divide both sides by y

x= 10/y

x= 10/(1±√11)

Check :

x*y = 10

[10/(1±√11)] * (1±√11) = 10

⇒[10/(1+√11)] * (1+√11) = 10✅

⇒[10/(1-√11)] * (1-√11) = 10✅

⇒[10/(1+√11)] * (1-√11) = 10❌

⇒[10/(1-√11)] * (1+√11) = 10❌

x-y = -2

⇒

[10/(1+√11) ] -(1+√11) =

[10 -(1+√11 )(1+√11 )]/ (1+√11 ) =

[10 - (1+11+2√11)]/ (1+√11) =

(10-12 -2√11) / (1+√11) =

(-2 -2√11) / (1+√11) =

-2(1+√11)/ (1+√11) =

-2 ✅

⇒

[10/(1-√11) ] -(1-√11) =

[10 -(1-√11 )(1-√11 )]/ (1-√11 ) =

[10 - (1+11-2√11)]/ (1-√11) =

(10-12 +2√11) / (1-√11) =

(-2 +2√11) / (1-√11) =

-2(1 -√11)/ (1-√11) =

-2 ✅

Answer:

y = 2x+6

Step-by-step explanation:

y is out

x is in

output = 6 more than twice the input

output = 6+2x

reorganize, 2x + 6

2x+6 = y

Answer:

C

Step-by-step explanation:

100 miles is the distance we know traveled in 2 hours. Therefore we can make this equation:

100 = 2x

100 / 2 =x

50 = x

We travel 50 miles an hour.

Now we know the x, 3.5 so lets plug that in:

3.5x = y

3.5(50) = y

175 = y

Therefore we travelled 175 miles in 3.5 hours.

I hope this helps! :)

Answer:

The speed is distance / time and speed times time equals distance

Step-by-step explanation:

speed = 100/2=50 mi/hr

distance =f(t)=50t

f(3.5)=50×3.5=175miles

hope that helps

The Boston Tea Party was a political protest that occurred on December 16, 1773, at Griffin's Wharf in Boston, Massachusetts.
