consider the expression 7 - 4y. Why would the co-efficient be -4 and not 4?

Answers

Because the answer to X is a negative number, and negative numbers are needed for negative answers

Answer: because it won’t make sense if it was 74y it has to have an equation or expression.

PLS HELP Anna buys bananas and apples. She buys 2 more apples than twice the number
of bananas. Altogether, Anna bought 14 fruits. How many apples did she buy?
(Hint use a bar model)
Your answer

Answers

Answer:

You have to put this in a bar model yourself so convert it later

She bought 10 apples

Step-by-step explanation:

3x + 2 = 14

why i did this

because she bought 2 times the amount of bananas, it should be x + 2x = 3x

then i added two because she bought two extra apples

so 3x+2 = 14

subtract 2

3x = 12

x = 4

So now we substitute x in apples

2x +2 = # of apples

8 +2 = 10

check

10 - 2 = 8

8/2 = 4

4 = # of bananas

Answer:

Anna bought 4 bananas and 10 apples.

Step-by-step explanation:

System of Equations

Let's call the following variables:

x = number of bananas Anna buys

y = number of apples Anna buys

She buys 2 more apples than twice the number of bananas, thus:

y = 2x + 2      [1]

Anna bought 14 fruits in total, thus:

x + y = 14      [2]

Substituting [1] in [2]:

x + 2x + 2 = 14

Simplifying:

3x = 12

Dividing by 3:

x = 4

Substituting in [1]:

y = 2*4+2 = 10

Anna bought 4 bananas and 10 apples.

Mode ??
Median ??

Answers

Answer:

No mode

Median 7

Step-by-step explanation:

Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.

Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Answer:

Mode: no mode

No mode because there are no repeating numbers.

Median=7

Put in order from least to greatest- 1,6,7,42,81

Find the one in the middle- 7

David and his 2 children are going to the zoo.
The administration price is
Adult:£60
Children:£67
FAMILY DISCOUND CARD GIVES
1/5 off adults price
60% off child price
Work out the total price David pays after using his discount card.

Answers

Answer:

£92.40

Step-by-step explanation:

Discount price for David =1/5 of 60

= 1/5 × 60/1

= £12 (5 multiplied by 12 is 60)

Price for one child = £67

Price for 2 children= £67 × 2

= 134

Therefore discount price for the children,

134 × 60/100

= 134 × 6/10

= 134 × 3/5

= 26.8 × 3

= 80.4

= £80.40

Therefore total Price David pays,

£80.40 + £12

= £92.40

Find the equation of the line: which passes through (1,-7) and is perpendicular to (-4,6) and (5,-3)

Answers

Answer:

-9 6 that is because the line has to be perpenducular to the other line

Step-by-step explanation:

Slope of line between points (-4, 6) and (5, -3)

=> Rise / Run

=> [6 - (-3)] / [(-4) - 5]

= 9 / (-9)

= -1.

Thus slope of perpendicular line

= -1 / (-1) = 1.

We have y = x + c.

When x = 1, y = -7.

=> (-7) = (1) + c, c = -8.

Hence y = x - 8.
