Is 27

U have to solve it by order of operation ( u start solving from right to left)
Order of operation in this case:
- ➗or✖️
- ➕or➖
So we can see that 70 divided by 7 is first so we solve it and it will give us 10.
Then we solve 8x3 which is 24, so now we have 24 +70+10-7, so the FINAL ANSWER IS 27

Answer:

27

Step-by-step explanation:

When solving complicated equations like this, we need to remember the order of operations (PEMDAS), which is the order that we solve an equation

P arentheses

E xponents

M ultiplication

D ivision

A ddition

S ubtraction

now, here's the thing: we actually to multiplication/division at the same time, and the same thing with addition/subtraction

(as in, adding -4 is the same thing as subtracting 4, so we can't truly make a distinction between the two)

so, when we have multiple instances of multiplication/division , we solve left to right

(and then the same thing for addition/subtraction)

8 <u>×</u> 3 + 70 <u>÷</u> 7 - 7

so, we first need to multiply 8 by 3

8 × 3 = 24

next, we move to the right:

and we divide 70 by 7

70 ÷ 7 = 10

let's rewrite our equation:

(24) + (10) - 7

24 + 10 - 7 = 27

so, the answer to this expression is 27

hope this helps!! have a lovely day :)

Find the discriminant of the following quadratic equation then state the number of rational, irrational, and imaginary solutions
lianna [129]

Answer:

  • -6x² - 6 = -7x - 9
  • -6x² + 7x - 6 + 9 = 0
  • -6x² + 7x + 3 = 0
  • 6x² - 7x - 3 = 0

<u>Discriminant:</u>

  • D = (-7)² - 4*6*(-3) = 49 + 72 = 121

<u>Since D > 0, there are 2 real solutions:</u>

  • x = (- (-7) ±√121 )/12
  • x = (7 ± 11)/12
  • x = 1.5, x = -1/3

A negative value of r means that:
tatuchka [14]

Answer:

(d.) Those who score high on one variable tend to score low on the other.

Step-by-step explanation:

A negative value of correlation coefficient (r) shows a relationship between two variables such that as one variable increases, the other decreases. It shows the inverse relationship between two variables with the dependence determined by the value of the correlation coefficient (r).

It can be observed that for graphs with negative slope, the correlation coefficient (r) is similarly negative. This speaks about its relationship too.

The correlation coefficient being negative doesn't mean the relationship between the two variables in question is bad, it just means that the correlation relationship is inverse (still dependent). A perfectly negative correlation is -1.

Whiskers the cat weighs 2 2/3 kg. Piglo weighs 4kg. For each question , write a myipulcation and a division equation, decide whe
Liula [17]

Answer:

1) x= 3/2=  1 1/2

2) x=  2/3

Step-by-step explanation:

1)How many times as heavy as  Whiskers is  Piglio?

a) Write a multiplication equation for the question.

2 2/3 kg  * [x]= 4kg

b) Write a division equation for the question.

4/ 2 (2/3) = x

c) Is the answer greater than 1 or less than 1?

Ans) Greater than 1                      

d) Find the answer

4/ 8/3= x

x= 3/2= 1 1/2

Pigilo is 1 1/2 times as heavy as whiskers

2)How many times as heavy as Piglio is Whiskers?

a) Write a multiplication equation for the question.

4 kg  * [x]=  2 2/3 kg

b) Write a division equation for the question.

2 (2/3)/4  = x

c) Is the answer greater than 1 or less than 1?

Ans) Less than 1                      

d) Find the answer

 8/3/4= x

  8/3 * 1/4= x

   2/3= x

Whiskers is 2/3 times as heavy as Pigilo.
