Answer:

The next  4 terms are -2.4, -8, - 13.6, 19.2.

Step-by-step explanation:

u1 = u0 - 5.6

= 3.2 - 5.6

= -2.4.

u2 = u1 - 5.6

= -2.4 - 5.6

= -8.

Answer:

[tex]\frac{3}{20}[/tex]

Step-by-step explanation:

15%

= [tex]\frac{15}{100}[/tex] ( divide numerator/ denominator by 5 )

= [tex]\frac{3}{20}[/tex]

Answer:

Step-by-step explanation:

okay so the equation is 3x - 12 = 78

add 12 on both sides

3x = 90

divide both sides by 3

x = 30

Answer:

The missing value (x) is 12.

Step-by-step explanation:

Given that there are two values already known, 78° and 78°, we can add them and get 156°.

Since a triangle has a total degree of 180°, we can do this:

180°-156° = 24°

So, now we have the missing angle and its equal to 24°.

what you now do is set 24°= 3x-12 to solve for x.

24°=3x-12

36=3x

/3

12=x

Answer:

x = -7/2

Step-by-step explanation:

-2(5x - 3) = 41

Distribute the -2 inside the parenthesis.

-10x + 6 = 41

Subtract 6 from both sides.

-10x = 35

Divide both sides by -10.

x = 35/-10

Simplify the fraction.

x = -7/2.

Proof:

-2(5x - 3) = 41

Substitute variable.

-2(5(-7/2) - 3) = 41

Multiply 5 and -7/2.

-2(-35/2 - 3) = 41

Turn 3 into a fraction with denominator 2.

-2(-35/2 - 6/2) = 41

Subtract 6/2 from -35/2.

-2(-41/2) = 41

Multiply -2 and -41/2.

41 = 41.

Answer:

I'm not the best with math either but the order is PEMDAS

Step-by-step explanation:

P: parenthesis

E: exponits

M: mutiplication

D: division

A: addation

S: subtraction

This means you would do the problems in parenthesis () first then go down the list here

Step-by-step explanation:

67 + x = 90

x = 90 - 67

x = 23°

Option → A

__________

[tex] \: [/tex]

67° + x = 90°

x = 90° - 67°

x = 23° (A.)

Answer: below(=

Step-by-step explanation: Given that,

dimensions of wall = 8.3ft by 7.5ft

height of wall = 8.3

width of wall = 7.5

there are total 3 walls in a bedroom to be painted blue.

Formula to calculate area of one wall

Height x Width

Formula to calculate area of four walls

3 (Height x Width)

= 3( 8.3ft x 7.5ft)

= 3 (62.25 ft²)

= 186.75 ft²

So area Alyssa will paint = 186.75 ft²

Answer:

the probability of drawing a green marble is 4/25 (16% or 0.16)

Step-by-step explanation:

Total: 16+8+9+12+5= 50

# of green marbles: 8

Event G, such that a green marble is drawn:

P(G)= 8/50

= 4/25 (16% or 0.16)

1inch=12miles

31/2 inches=(31/2x12) miles

=(7/2x12) miles

=(7x6) miles

=42miles.

Answer:

28

Step-by-step explanation:

Prime factorization of 84 is 2^{2} × 3 × 7.

Prime factorization of 56 is 2^{3} × 7.

GCF = 2 × 2 × 7

       = 28

I hope it helps.

Answer:

-2

Step-by-step explanation:

From the graph, it appears that (0, 2) and (2, -2) are points on the line.  (Othere points will work, as well; you just need two points.)

Slope = (difference between the y coordinates) / (difference between the x coordinates)

One phrase to remember this is slope = "rise over run"  (vertical change divided by horizontal change from point to point).

Slope = (-2 - 2) / (2 - 0) = -4 / 2 = -2

The slope is -2.

Answer:

o=54

Step-by-step explanation:

m=180-(78+22)

m= 80

O= 180-(80+24+22)

O=54

Answer:

4 -9/20

Step-by-step explanation:

separate whole numbers and fractions: 9-5, 3/10 - 3/4

then you subtract the whole numbers: 4

after that (what i mostly use that is easy for me is cross multiplication/ Butterfly method)

12    -     30

3      -      3    =   -18  = -9

10            4         40     20

Answer:

less than 55 minutes

Step-by-step explanation:

11 laps at 5 minutes per lap is 55 minutes.

Since she will run fewer than 11 laps, she will run less than 55 minutes.

Answer:

Y = -1/2 x

Step-by-step explanation:

To write the equation in slope intercept form

Y = mx + c

C is y-intercept

the graph is passing through centre. That means y-intercept is zero.

so C=0

To find m which is slope,

[tex] \frac{rise}{run} [/tex]

rise = 10

run= -20

[tex] \frac{10}{ - 20} \\ \frac{ - 1}{2} [/tex]

So

[tex]y = \frac{ - 1}{2} x[/tex]

Answer:

Step-by-step explanation:

Answer:

6x^3 - 16x^2 - 14x + 24

Step-by-step explanation:

(x - 1)(x - 3 ) = x^2 - 3x - x + 3

2 (3x + 4) = 6x + 8

(x^2 - 3x - x + 3) (6x + 8)

= 6x^3 + 8x^2 - 24x^2 - 32x + 18x + 24

= 6x^3 - 16x^2 - 14x + 24

Answer:

P(3) = 0.2

Step-by-step explanation:

P(4) = 0.1

P(1) = 0.5

this leaves 1.0 - 0.6, or 0.4, to be split between the numbers 2 and 3

Answer: 25.89

Step-by-step explanation: first I do 796.65÷47 which gives us 16.95 and then I do 402.30÷45 which gives us 8.94 and then I add 8.94 and 16.95 together which is 25.89
