[tex]0,4(5x-15)=2,5(x+3)\\\\2x-6=2,5x+7,5\\\\2x-2,5x=7,5+6\\\\-0,5x=13,5 \ \ /\cdot(-2)\\\\\huge\boxed{x=-27}[/tex]

Answer:

Answer:

x=−27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.4(5x−15)=2.5(x+3)

(0.4)(5x)+(0.4)(−15)=(2.5)(x)+(2.5)(3)(Distribute)

2x+−6=2.5x+7.5

2x−6=2.5x+7.5

Step 2: Subtract 2.5x from both sides.

2x−6−2.5x=2.5x+7.5−2.5x

−0.5x−6=7.5

Step 3: Add 6 to both sides.

−0.5x−6+6=7.5+6

−0.5x=13.5

Step 4: Divide both sides by -0.5.

−0.5x

−0.5

=

13.5

Answer:

115

Step-by-step explanation:

Area is 180 so 180-67-48=65 so 180-65 is 115

Answer:

We know that ,

Exterior angle of a triangle is equal to sum oposite two interior angles

So,

The total cost of the camera is $73.84

Since Vijay bought a camera that was marked down 80% from the original price of $355, then the amount paid will be:

= $355 - (80% × $355)

= $355 - (0.8 × $355)

= $355 - $284

= $71

Since there is a 4% sales tax, then the total amount paid will be:

= $71 + (4% × $71)

= $71 + (0.04 × $71)

= $71 + $2.84

= $73.84

The total cost of the camera is $73.84

Work Shown:

5 green discs

7+5+2 = 14 discs total

5/14 is the probability of getting a green disc

(5/14)*140 = 50 green discs are expected if 140 trials are conducted.

The no. of green discs she expects by replacing and drawing again for 140 times is 50.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given A bag contains 7 red discs, 5 green discs, and 2 pink discs.

So, no. of sample space N(S) = 7 + 5 + 2 = 14.

∴ The probability of getting a green disc P(G) = N(G)/N(S).

P(G) = 5/14.

Now she replaces the discs drawn and picks one random disc from the bag again 140 times,

Therefore the probability of getting a green disc will remain the same as an independent event because of the replacement.

∴ The no. of green discs she expects is (5/14)×140 = 50 times.

Step-by-step explanation:

Alright so the two dashes in a line means they are equivalent so if I only give one final answer use it for both...

D: 180-52=128 now divide by two since equal angles so 64 degrees for the angles

E: 180-90=90, 90/2 so 45 degrees for those angles

F: okay interesting 180-130= 50 degrees so that's the inside angle there for x and y so to find z its 180- 100 which is 80 x&y is 50 while z's 80

G: 180-36=144 divide that by two and viola 72 is the answer

H: the angle of 86 is correct since mirrored. so x is 86. now for the unlisted angle 180-124= 66 so to find y 86+66=152 so 180-152=28. So x=86 y=28 and the unlisted is 66.

Answer:

Step-by-step explanation:

We use the top formula since x = -4

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

g(-4) = [tex]\sqrt[3]{1}[/tex]

g(-4) =1

let the last number be x

we know,

[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]

So,

[tex] \hookrightarrow \: 8 = \dfrac{22 + x}{4} [/tex]

[tex] \hookrightarrow \: 8 \times 4 = 22 + x[/tex]

[tex] \hookrightarrow \: 32 = 22 + x[/tex]

[tex] \hookrightarrow \: x = 32 - 22[/tex]

[tex] \hookrightarrow \: x = 10[/tex]

therefore, the last number is 10.
