25d-16=4d+26
whats d?

Answers

Answer 1
Answer: Like terms are when the variable you have are the same. In this case it is x. Therefore, when you have like terms, you should add, or subtract your like terms.

(note: When you move one thing to the other side of the equation, make sure to do the opposite of the sign. i.e. if it is +26 when you move to the other side it will be -26).

25d-16=4d+26
25d-16+16=4d+26+16
25d=4d+26+16
25d-4d=4d-4d+26+16
25d-4d=26+16
21d=42
this is the same as:
21*d=42
the opposite of multiply is divide so when we move the 21 it has to be divide
21/21*d=42/21
d=2
Answer 2
Answer: For this question you should first add -4d on both sides of the equation and then add +16 on both sides:
25d - 4d = 26+16 
21d = 42 
d = 42/21 
d = 2 :)))

Which of the following is the solution to the inequality below?-5x - 10 < 20 ?

1) x > -6
2) x > - 2
3) x < -6
4) x< -2

Answers

Add 10 to both sides.

This gives us -5x < 30.

Now divide both sides by -5.

When you divide both sides of
an inequality by a negative, switch
the direction of the inequality symbol.

So we have x > -6.

10. John is mixing paint.He uses black, green and blue in the ratio 6:3: 1. How much of black green and blue paint is needed to make a mixture of paint of 500ml.​

Answers

The given ratio becomes 6x : 3x : x.

6x = black paint

3x = green paint

x = blue paint

6x + 3x + x = 500

10x = 500

x = 500/10

x = 50

6x = 6(50) = 300

3x = 3(50) = 150

x = 50

Answer:

300 ml of the black paint.

150 ml of the green paint.

50 ml of the blue paint.

A rhino can run at speeds of about 28 miles per hour. What is that speed in feet per second, to the nearest whole number? (Remember, there are 5280 feet in a mile, 60 seconds in a minute, and 60 minutes in an hour.)A.189 feet per second
B.88 feet per second
C.36 feet per second
D.41 feet per second

Answers

We have 28 mph.
To convert that to feet we would multiply that by 5,280.
To convert that to seconds we have to divide it by 3,600.
So, basically we have to get 28 and multiply it by 5,280 / 3,600 and that equals
41.066666666 feet per second.
Answer is D

Answer: 41 feet per second
