Can somebody help me with these 3. Will mark brainliest.

Answer:

13.65

Step-by-step explanation:

Answer: 7

Step-by-step explanation: First distribute the subtraction sign (negative one) to x and -3. Now we have 12 -1x + 3 = 8. Now combine 12 and 3 then subtract 15 from both sides to get -1x = -7. Now divide both sides by -1 to get x = 7.

Hope this helps!

Answer:

Step-by-step explanation:

12-(x-3) =8

12 -x +3 = 8

15 - x = 8

- 15.    -15

-x = -7

x = 7  

Answer:

When fractions have different numbers in them, but have the same value, they are called equivalent fractions.

The question is incomplete the complete question is

Evaluate (4/9) to the power of 2.

We have given that,

(4/9)^2

Apply the product rule to 4/9.

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]

[tex]=\frac{4^2}{9^2}[/tex]

[tex]4^2=16[/tex]

[tex]=\frac{16}{9^2}[/tex]

[tex]9^2=81[/tex]

[tex]=\frac{16}{81}[/tex]

Therefore the (4/9) to the power of 2 is equal to [tex]\frac{16}{81}[/tex].

Answer:

I think it is

1: 22.37

2:16.81

3:83.16

Step-by-step explanation:

Answer:

Shape 1: 22.365

Shape 2: 16.81

Shape 3: 83.16

Step-by-step explanation:

I'm going to start with 2, because its the easiest shape to do, which is 4.1*4.1= 16.81. Next is 3, which you find the length by adding 4.1 to 9.1 = 13.2. You then multiply 13.2 by 6.3 = 83.16. Finally for shape 1, you first find the bottom shape,  which you do by dividing 6.3 by 2 so you can get the width of half the triangle. That is 3.15. then you multiply that by 7.1 to get the area of 22.365.

[tex]18x + 8= (180 - 46) = 134 \\ 18x = 126 \\ \boxed{x = 7}[/tex]

Answer:

A=30 is the smallest side

Step-by-step explanation:

A+B+C= 180

30+70+C=180

100+C=180

C=180-100

C=80

Therefore, A=30 is the smallest side of the triangle...

Answer:

$25

Step-by-step explanation:

Given that:

Cost of Ashley's dinner in Bloomington = $20

Sales tax = 10%

Tip = 15% on $20

To find:

Total cost of the meal ?

Solution:

Let us find the sales tax first of all.

Sales tax is 10% of the total bill.

Therefore, sales tax = 10% of $20

[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]

Tip left is 15% of the total bill.

Therefore, tip = 15% of $20

[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]

Now, total cost of the meal = Food cost + Sales tax + tip

Total cost of the meal = $20 + $2 + $3 = $25

Step-by-step explanation:

Answer:

B: 8^3 in squared

Step-by-step explanation:

2^3 = 2*2*2= 8

4^3 =4*4*4=64

Area of rectangle equals length times width.

So, 8 * 64 equals 512 and 8^3= 512

Use calculator. Also, you can just treat it as normal multiplication and choose the one with the same units. so it would be 8, but then the next thing you would need to look at is the exponent. Since 8^6 is not the same exponent as the two in the problem, it has to be the 8^3, which are the same  

Answer:

20163.299

Step-by-step explanation:

Initial value = 8100

Rate r = 0.95% = 0.0095

t = 96 month

Therefore, Value of the quantity after 39 decades = Initial value*e^(rt)

= 8100*e^(0.0095*96)

= 8100*e^(0.912)

= 8100*2.48929615041

= 20163.298818321

= 20163.299

So, the value of the quantity after 96 months is 20163.299

Answer:

x = 26, y = 19

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{ST}{NP}[/tex] = [tex]\frac{RS}{MN}[/tex] , substitute values

[tex]\frac{x}{13}[/tex] = [tex]\frac{32}{16}[/tex] = 2 ( multiply both sides by 13 )

x = 26

and

[tex]\frac{MP}{RT}[/tex] = [tex]\frac{MN}{RS}[/tex] , substitute values

[tex]\frac{y}{38}[/tex] = [tex]\frac{16}{32}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 38 ( divide both sides by 2 )

y = 19

Answer:

down below

Step-by-step explanation:

set up two equations:

x + 4 = 6                    x + 4 = -6

solve both:

x = 2                          x = -10

plug it back in to the original equation:

|2 + 4| = 6.                 |-10 + 4| = -6

|6| = 6.                       |-6| = -6

6 = 6.                         since absolute value is always positive:

correct.                     |6| = -6

                                6 does not = -6

write both of these down if you need to show your work
