The value of the expression using distributive property is -3/7 .

According to the distributive property, an expression of the form A (B + C) can be resolved as A (B + C) = AB + AC. This distributive law, which is represented as A (B - C) = AB - AC, also applies to subtraction. This indicates that the distribution of operand A among the other two operands.

We learn how to solve expressions in the form of a(b + c) from the distributive property. The distributive law of multiplication and division is another name for the distribution property.

The given expression is  4/5 x -3/7  +  1/5 x -3/7

Here we take the reverse of the distributive property to solve the expression. We take the term of 3/7 common from both the separate expressions

4/5 x -3/7  +  1/5 x -3/7

= -3/7  x (4/5 +1/5)

=  -3/7 x 5/5

= -3/7 x  1

= -3/7

35 teenagers were asked what takeaways they liked to eat.
STatiana [176]

The number of teenagers that liked Indian only is 11 students.

<h3>How to use Venn Diagrams?</h3>

Counting students who liked Chinese and pizza

There were 35 teenagers altogether.

  • 24 liked Chinese
  • 16 liked Indian
  • 10 liked pizza

Since all the students who liked pizza also liked Chinese, and no student liked all three, we can just think about the remaining 25 students.

Of these, 14 liked Chinese and 16 liked Indian.

Since each student liked at least one of these, and there are a total of 30 'likes', then 5 students must like both Indian and Chinese.

This leaves 11 students who liked Indian only.

Thus, we conclude that the number of teenagers that liked Indian only is 11 students.

Sonia and Layla are both running for class president. The senior class has 220 students. After 60% of
puteri [66]

Answer: 33 votes

Step-by-step explanation:

First, we have to calculate 60% of 220 to Kno.the number of people who voted. This will be:

= 60% × 220

= 0.6 × 220

= 132 students

Sonia has received 25% of the casted votes. The number of votes Sonia got will be:

= 25% × 132

= 0.25 × 132

= 33 votes

Layla has received 75%. Her votes will be:

= 75% × 132

= 0.75 × 132

= 99 votes.

50% of the total votes will be:

= 50% × 132

= 0.5 × 132

= 66 votes

The number of votes needed by Sonia to receive 50% of the total votes will be:

= 66 - 33

= 33 votes
