Picture relating to question is attached below

Answer:

t > - 5

Line is in the wrong side

Step-by-step explanation:

Given the inequality :

50 – 8t < 90

-8t < 90 - 50

-8t < 40

-8t / - 8 < (40/ - 8)

t > - 5 (sign changes)

During simplification, we should observe that the inequality sign changes due to negative sign. Hence, our final inequality equation read t > - 5 ; thus, arrow should point to the right

White raven [17]

answer ?

30 or 30W

Step-by-step explanation:

this isn't a real equation. you can't have an equal sign inside a parentheses but assuming that the question is 6(W) and W equals 5, we can substitute the 5 and distribute the 6 to get 6x5 = 30

5(x-3)+2x+21=3(x+4)+2x
nekit [7.7K]

Answer:

x = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−3)+2x+21=3(x+4)+2x

(5)(x)+(5)(−3)+2x+21=(3)(x)+(3)(4)+2x(Distribute)

5x+−15+2x+21=3x+12+2x

(5x+2x)+(−15+21)=(3x+2x)+(12)(Combine Like Terms)

7x+6=5x+12

7x+6=5x+12

Step 2: Subtract 5x from both sides.

7x+6−5x=5x+12−5x

2x+6=12

Step 3: Subtract 6 from both sides.

2x+6−6=12−6

2x=6

Step 4: Divide both sides by 2.

Hope this helps!

How do you do this?<br>Also please explain!:)​
White raven [17]

Answer:

answer b (0.73)

Step-by-step explanation:

"Triple" means to increase in size by a factor of 3.  

Thus, B = (1 + r)^2 becomes

3 = (1 + r)^2.  Our task is to determine the value of r, the annual interest rate.

Taking the square root of both sides, we get

√3 = 1 + r, which yields √3 - 1 = r.

This is approx. 1.732 - 1.000, or 0.732.  Answer b) is closest.
