It t takes 5 identical robots 12 days to paint a long straight wall. How many robots will it take to paint wall in 20 days?

Answer:-18

Step-by-step explanation:

6(x−3)+x=7x−18

Step 1: Simplify both sides of the equation.

6(x−3)+x=7x−18

(6)(x)+(6)(−3)+x=7x+−18(Distribute)

6x+−18+x=7x+−18

(6x+x)+(−18)=7x−18(Combine Like Terms)

7x+−18=7x−18

7x−18=7x−18

Step 2: Subtract 7x from both sides.

7x−18−7x=7x−18−7x

−18=−18

Step 3: Add 18 to both sides.

−18+18=−18+18

Answer:

750/100 X 7 = 52.50

52.50 X 3 = $157.50

Step-by-step explanation:

divide principal amount by 100 then multiply by interest percentage. this gave 52.50

now multiply the interest amount by number of years

in this case 3

52.50 X 3 = $157.50

Step-by-step explanation:

[tex] step - 1 : define \\ - 8 = \frac{x}{3} + 1[/tex]

[tex]step - 2 : \\ rewrite[/tex]

[tex]\frac{x}{3} + 1= - 8[/tex]

[tex]step - 3 : \\ subtract \: 1 \: from \: both \: sides[/tex]

[tex] \frac{x}{3} + 1 - 1 = - 8 - 1[/tex]

[tex] \frac{x}{3} = - 9[/tex]

[tex]step - 4 : \\ multiply \: both \: sides \: by \: 3[/tex]

[tex] \frac{x}{3} \times 3 = - 9 \times 3[/tex]

Answer:

13.6

Step-by-step explanation:

Remember SOH CAH TOA

We're going to use tangent = opposite / adjacent because the 11 is opposite theta (39 degrees) and x is adjacent to it.

tan (39) = 11 / x

x = 11 / tan(39)

x = 13.584 -> 13.6 (rounded to nearest tenth)

Note: Make sure your calculator is in degree mode.

Answer:

532381.5

Step-by-step explanation:

456327 divided by 6 to get 1/6 = 76054.5

76054.5 x 7 to get 7/6 = 532381.5

or 456327 (6/6) + 76054.5 (1/6) =532381.5

Answer: 2x+17

Step-by-step explanation: add -5 and 22

______________________________

 - You could also solve this by  flipping the numbers around and subtracting 22 - 5, Which still gives you 17.

So your answer is [tex]\bold{(2x+17)}[/tex].

Answer:

-9°F

Step-by-step explanation:

If we have a horizontal line in which the zero is in the middle, the positive numbers are on the right and the negative numbers are on the right, we would see that -9°F is further than 6°F. Even though -9°F is a smaller temperature, it is still further away from the zero.

Answer:

6.3

Step-by-step explanation:

8.5 - (-4.8)

Let's focus on - (-4.8)

if a negative number is subtracted, it reverses itself

In other words, if a negative number is being subtracted, it is the same as being added as a positive number

So we change the equation to

8.5 + 4.8 = 13.3

Now we subtract 7 from 13.3

Since positive 7 is being subtracted, the rule for -4.8 does not apply to it

13.3 - 7 = 6.3

Answer:

2.36 * 10^13 miles

Step-by-step explanation:

Given that :

Proxima centauri is at a distance of 4.24 light years away from the sun.

Distance in miles of Proxima centauri from the sun ;

1 light year = 5.9 * 10^12 miles

Number of light years from the sun * 5.9 * 10^12

= 4 * (5.9 * 10^12)

= 23.6 * 10^12 miles

= 2.36 * 10^13 miles

Answer:

Tn = 8n - 2

Step-by-step explanation:

Given the arithmetic sequence

6, 14, 22, 30, 38

The nth term is expressed as;

Tn = a +(n-1)d

a is the first term = 6

d is the common difference = 14 - 6 = 22 - 14 = 8

Substitute into the formula;

Tn = 6 + (n-1)(8)

Tn = 6 + 8n-8

Tn = 8n - 2

Hence the nth term of the sequence is 8n-2

Answer:

right triangle it is because if u make a graph and put the points u would get a right isosclses triangle

Step-by-step explanation:

The triangle ABC with verticies A(3, 3), B(6, 9) and C(6, -3) is an isosceles triangle.

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

Given, A ΔABC with verticies A(3, 3), B(6, 9) and C(6, -3).

We know the distance formula [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].

From this we find AB = √45 units, BC = 12 units and AC = √45 units.

Now, this is an isosceles triangle with two equal sides of √45 units.
