PLSSS HELP! can someone answer these two questions from my math homework!

Mathematics
1 answer:
blagie [28]3 years ago
4 0

Answer:

1) 120

2) 186

Step-by-step explanation:

so you need to use BIDMAS (if your from the UK, I think its called PEMDAS in the US but I'm not sure)

so first you need to work out what's inside the brackets/parentheses

7(18-6)+12(4-1) = 7(12) + 12(3)

then you need to do multiplication/division

7(16) +12(3) = 7x12 + 12x3 = 84 + 36

finally you do addition/subtraction

84+36 =120

just repeat the same process for question 2

26 + 8(126÷6) - 8 = 26 +8(21) - 8

                             = 26 + 8x21 - 8

                             = 26 + 168 - 8

                             = 186

Identify the variation as direct, inverse, joint or combined.
Len [333]

Answer: Third option.

Step-by-step explanation:

<h3> The exercise is actually: "Identify the variation as direct, inverse, joint or combined:  V=r^2h"</h3><h3> </h3>

For this exercise it is important to remember that, by definition, a Joint variation is that variation in which one variable depends on two or more variables and  there are a direct relation between these variables.

In this case, you have the following equation given in the exercise:

V=r^2h

 Let's assume that "r" and "h" are variables.

You can identify that:

  1. The variable "V" depends on the variables "r" and "h".
  2. The variables are related directly.

So, based on this, the variation can be read as:

<em>"V" varies jointly with the square of "r" and "h".</em>

Therefore, you can conclude that the  given variation is: Joint.

Combining like terms just means putting together all the same variables. On the left side, 5x + x + x are all like terms and yoh get a total of 7x. Then -6 - 2 is -8. Left side in total is 7x - 8. As for the right side, is "a" a variable too?
