Answer:

Each girl earned 2 points

Each boy earned 5 points

Step-by-step explanation:

Let x represent the number of points one girl earned

Let y represent the number of points one boy earned

4x + 2y = 28

4x - 2y = 12

8y = 40

y = 5 points

4x + (2)(5) = 28

4x + 20 = 28

4x = 8

x = 2 points

Each girl earned 2 points

Each boy earned 5 points

Hey there!

The answers are as follows:

7.)

m∠1 = 85

m∠2 = 95

m∠3 = 85

m∠4 = 85

8.)

m∠1 = 60

m∠2 = 120

m∠3 = 60

m∠4 = 120

9.)

they all equal 90

10.) No. Parallel lines do not cross each other, but these, if extended, would cross. You could use a protractor by measuring corresponding angles, and if they aren't equal, they aren't parallel.

Answer:

1/15

Step-by-step explanation:

1/5 divided by 3

=1/5 times 1/3

=  1 × 1

 -------

 5 × 3

= 1/15

Answer:

The answer is 1/10

Step-by-step explanation:

1/5 divided by 2

1/5 times 1/2

1 x 1 = 1

5 x 2 = 10

1/10

Answer:

y= -a*x + 12

b b

Step-by-step explanation:

ax+by=12 (subtract "ax" from both sides so that the one on the left will become zero and we will have "by" )

by= -ax+12(divide both side by "by" so that we will have the equation as "y=mx+b")

finally the result will be:

y= -a*x + 12

b b

Answer:

Kindly check explanation

Step-by-step explanation:

A common problem with most research designs is bias, which could be introduced win several ways one if which is the favored selection of certain variables rather than being randomized. In the scenario above, the sampling time frame introduces a bias into the design as the tune span of pesticide use does not allay with that of the exposure history of the respondent. Therefore an entire lifetime evaluation of one variable and just 20 years evaluation of the other introduces a sampling bias into the research design. Similarly, evaluation the type of pesticide usage over certain time period may need to be considered as the effect of very old pesticides may differ from those used very recently.

Answer:

4

Step-by-step explanation:

3.3 + -1 is 2.3

2.3 - -1.7 is 4

Answer:

Pretty sure it's A

Answer:

f(n) = -6n - 10.

Step-by-step explanation:

This is arithmetic sequence with first term a1 = -16 and common difference d = -6.

So f(n) = a1 + d(n - 1)

= -16 - 6(n - 1)

= -16 - 6n + 6

= -6n - 10.

Checking:

f(10) = -6(10) - 10 = -70.

The function that defines the sequence is f(n) = -6n - 10.

A sequence of numbers which have a relation between them and the consecutive numbers increase or decrease by a fixed amount is called as an Arithmetic Sequence.

The sequence given is -16,-22,-28,-34

This is arithmetic sequence

first term a1 = -16

common difference d = -6.

The nth term of an arithmetic sequence is given by

f(n) = a1 + d(n - 1)

f(n) = -16 - 6(n - 1)

f(n)= -16 - 6n + 6

f(n)= -6n - 10.

To verify this

f(10) = -6(10) - 10 = -70.

Therefore , The nth term is given by f(n)= -6n - 10.

Answer:

D. 28,923

Step-by-step explanation:

We are given four numbers and are asked to find out which number is odd.

An odd number is a number that cannot be split evenly, if it is split, it will end up in either a fraction or a decimal.

Even numbers are the opposite, so which would be the answer?

This would be D. 28,923. 28,923 divided by 2 gives you a decimal. Which is 14461.5, all the other choices give you whole numbers.
