Here we have first number as positive 43 and the second number is (-35)

so we have to subtract here 43 and (-35)

We will use the following property here:

a-(-b) =a+b

So that means the two negatives will make positive sign,

43-(-35) =43+35

On adding 43 and 35 , we will get 78

Answer: +43-(-35)=78

43+35=__
After that just add

After going on a diet,Amy finds that her weight has decreased by 25%.If her weight now is 75kg how much does her weight before?​
Rainbow [258]

Answer:

Her weight before was 100kg.

Step-by-step explanation:

This question can be solved using a rule of three.

Amy finds that her weight has decreased by 25%

So her weight is 100-25 = 75% = 0.75 of the original amount(what it was before).

Her current weight is 75kg.

Her previous weight was x, which is 100% = 1.

So

75 - 0.75

x - 1

0.75x = 75

x = \frac{75}{0.75}

x = 100

Her weight before was 100kg.

A teacher gave a test to a class in which 10% of the students are juniors and 90% are seniors. The average score on the test was
IceJOKER [234]

Each junior  receives 93 score on the test. It is also the average score of the juniors.

Given Information

It is given that 10% of the strength of the class consists of juniors and 90% consists of seniors.

Let us assume the total strength of the class is 100, then,

Number of seniors = 90

Number of juniors = 10

It is also given that the average score of the class = 84

And, average score of the seniors = 83

Another given information is that all the juniors all received the same score, which is their average score. Let it be x.

Average Score of Juniors

Total marks obtained by the seniors = Number of seniors × Average score of seniors

= 90 × 83

= 7470

Total marks obtained by the juniors = Number of juniors × Average score of juniors

= 10x

Average marks on the test = Total marks / Total number of students

⇒ 84 = (7470 + 10x)/100

⇒ 84 × 100 = 7470 + 10x

⇒ 10x + 7470 = 8400

⇒ 10x = 8400-7470

⇒ 10x = 930

⇒ x = 930/10

⇒  x = 93

Thus, each junior scores 93 on the test.
