Answer:

(-4, 5)

Step-by-step explanation (work shown in attached picture):

1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.

2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.

Since x = -4 and y = 5, the solution is (-4, 5).

Step-by-step explanation:

since perimeter is the length of all the sides added up, and the sides of a square are all equal, you just add up all the sides!

Answer:

0

Step-by-step explanation:

-9x -3(2) = 6

-9x + 6 = 6

-9x + 6 -6 = 6-6

-9x/ -9= 0/-9

x=0

Answer:

1

Step-by-step explanation:

Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.

The average value of a function f(x) over an interval [a, b] is

                  f(b) - f(a)

ave. val. = ---------------

                     b - a

which in this particular case is

                     19 - 30

ave. val. = ----------------- = -11/11 = 1

                     6 - (-5)

The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.

Answer:

6/10 kg

Step-by-step explanation:

Ed bought 4 pieces of salmon weighing a total of 2 kilograms. One piece weighed 4/10 kg, and two of the pieces weighed 5/10 kg each. What was the weight of the fourth piece of salmon? Explained

Hence:

Total kg of salmon = 4/10 + 5/10 + 5/10 + fourth piece

Total kg = 2 kg

Hence,

Fourth piece = 2 kg - ( 4/10 + 5/10 + 5/10) kg

Lowest common denominator = 10

2 kg - (4 + 5 + 5/10)

2kg - (14/10)kg

2 kg - 1 4/10 kg

= 6/10 kg

The weight of the fourth piece =

6/10 kg

Answer:

Hot dogs: $2.75

Sodas: $1.5

Step-by-step explanation:

Hot dogs = x

Sodas = y

4x + 3y = 15.5

3x + 2y = 11.25

First find the value of the hot dogs by canceling out y:

2(4x + 3y) = 2(15.5)

3(3x + 2y) = 3(11.25)

= 8x + 6y = 31

9x + 6y = 33.75

x = $2.75 (Minus bottom equation from the top to isolate x)

Plug in for x to get y:

3(2.75) + 2y = 11.25

2y = 11.25 - 8.25 (Isolate the y)

2y = 3

y = 3/2, or $1.5

Answer:

1.9 feets (nearest tenth) ;

24.9 feets

Step-by-step explanation:

Given that :

Angle, θ = 4.3°

Length of ramp = 25

Maximum Height, h ;

sinθ = opposite / hypotenus

Sin 4.3 = h / 25

0.0749787 * 25 = h

1.874 feet = h

1.9 feets (nearest tenth)

Distance along the ground the ramp could cover :

Cos θ = Adjacent / hypotenus

Cos 4.3 = x / 25

0.9971851 = x / 25

0.9971851 * 25 = x

x = 24.929

x = 24.9 (nearest tenth)

Step-by-step explanation:

A 90 degree triangle will seperate into three sides equalling 90 degrees.

90          75

-25         -21

= 75       =54

The third side is 54 degrees, I believe. Haven't done this in a while so I apologize if I made any mistakes.

Answer:

[tex]\boxed {\boxed {\sf 596.4 \ kilometers}}[/tex]

Step-by-step explanation:

Let's create a proportion using this setup.

[tex]\frac {liters}{kilometers} = \frac{liters}{kilometers}[/tex]

We know that 25 liters are used for 355 kilometers.

[tex]\frac {25 \ liters}{355 \ kilometers} = \frac{liters}{kilometers}[/tex]

We don't know how many kilometers are used with 42 liters. Therefore we say x kilometers are used for 42 liters.

[tex]\frac {25 \ liters}{355 \ kilometers} = \frac{42 \ liters}{x \ kilometers}[/tex]

[tex]\frac {25 }{355 } = \frac{42 }{x}[/tex]

Cross multiply. Multiply the first numerator by the second denominator, then the first denominator by the second numerator.

[tex]25*x=42*355[/tex]

[tex]25x=14910[/tex]

Since we are solving for x, we need to isolate the variable. x is being multiplied by 25. The inverse of multiplication is division, so divide both sides by 25.

[tex]\frac{25x}{25}=\frac {14910}{25}[/tex]

[tex]x=596.4[/tex]

The car can travel 596.4 kilometers with 42 liters of fuel.

Answer:

If the base of the prism has dimensions x and y, and the diagonal along the base is represented by c, then x² + y² = c². The longest diagonal in the solid, s, is the hypotenuse of the triangle formed by the sides c and the height of the solid, z. So we know that, c² + z² = s².

Answer: -1171875

Step-by-step explanation:

From the question,

a = first term = -3

r = common ratio = 5

The ninth term will be:

= ar^8

= -3 × 5^8

= -3 × 390625

= -1171875

Therefore, the ninth term is -1171875.

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

one cubic cm would be 2x2x2=8 half cm³

you have 1x2x2.5 cm cube = 5 cm³

5 x 8 = 40

another way to look at it:

2 1/2 = 5 half-cubes long

2 = 4 half cubes wide

1 = 2 half cubes tall

5 x 4 x 2 = 40
