Solve the system of equations using the substitution method.
{y=2 2x+y=8

Answers

Answer 1
Answer: x=3

Explanation:

Substitute y with 2, so it would look like this:
2x+(2)=8

Then, subtract 2 (as it is by itself) from 8, which is on the other side, and it’ll look like this:
2x=6

Divide by 2 from both sides to isolate the variable, and you should get your answer:
x=3

Your promotional budget for the year is $300 for personal selling, $300 for sales promotion, \$1,500 for advertising, and $500 for image promotion. What is your total promotional budget for this year?

a) $2,000

b) $2,600

c) $3,600

d) $4,600

Answers

Answer:

to get the total promotion budget for the year we will add $300 for personal selling plus $300 for sales promotion plus $1500 for advertising plus $500 for image promotion to the a total of 2600 dollars

The total promotional budget for this year should be considered as the $2,600.

Calculation of the total promotional budget:

Since there is $300 for personal selling, $300 for sales promotion, \$1,500 for advertising, and $500 for image promotion.

So,

= $300 + $300 + $1,500 + $500

= $2,600

hence, the correct option is b.

The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than the youngest.

Answers

Answer:

the oldest sibling is 12 years old.

The middle child is 9 years old.

The youngest child is 6 years old.

Step-by-step explanation:

Let the age of the youngest child be x

Then the oldest child will be 2x.

The middle child will be x + 3.

Since the combined age is 27;

x + 2x + x + 3 = 27

4x = 27 - 3

x = 24 / 4

x = 6

now 2x = 12 and x + 3 = 9

Answer:

oldest is 12

middle is 9

youngest is 6

all add up to 27

Step-by-step explanation

idk if i did this right but i did 27 -3 =24

then i divide 24 by 2 which is twelve (the oldest's age)

then 12 divided by 2 is 6 which is the age of the youngest one

6 + 3 is 9, which is the age of the middle one.

Jada volunteers at an animal shelter that holds picnics to introduce people to animals. For the first picnic, she brought 36 clementines for 16 people, which was the right amount. For the next picnic, there will be 40 people!

How many clementines should Jada bring for all those people? Explain or show your reasoning.

Answers

36/16=2.2=2
40x2=80

therefore she will need 80 oranges.

Jada would have brought 90 clementines for all those people.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
For 40 people number of clementines be x,
So, as for the proportional relationship.
16 / 36 = 40 / x
x = 40 [36/16]
x = 10[9]
x = 90

Thus, Jada would have brought 90 clementines for all those people.

List the following in order from least steep to most steep.
f(x)= -3/4x
g(x)= -5x
h(x)= 5/7x
j(x)= 11/3x

Answers

Answer:

h(x), f(x), j(x), g(x)

Step-by-step explanation:

Given functions

f(x)= -3/4x g(x)= -5x h(x)= 5/7x j(x)= 11/3x

To compare steepness we'll compare absolute values of slopes

The steepness increases as the slope increases

The slopes are

3/4, 5, 5/7, 11/3

Comparing the fractions

3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7

And

11/3 < 4  

So the order is

5/7 < 3/4 < 11/3 < 5

As functions, the order is

h(x), f(x), j(x), g(x)
