Answer:
34:103
Step-by-step explanation:
Add up all the numbers and then put gold then : then the numbers added up
A proportion exists an equation that sets two ratios at the same value.
34 : 103 exists the ratio of gold medals to the total number of medals that the team won 103.
What is the difference between ratio and proportions?When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage. A ratio is a comparison between two values. A ratio is created when two ratios are equal.
If a ratio depicts the same relationship, it is proportionate. Two ratios can be written as fractions and then reduced to determine if they are proportionate to one another. You have proportionate ratios if the reduced fractions are equal.
Use ratios to compare two things.
The formula for the ratio of any two quantities is expressed as
a : b ⇒ a/b.
On the other hand, the proportional formula is
a : b :: c : d ⟶ ab = cd
a : b :: c : d ⟶ ab = cd

1. Solve the equation:
-(1+4x)=4(1-x)-5*
(5 Points)
Steps to solve:
-(1 + 4x) = 4(1 - x) - 5
~Distribute both sides
-1 - 4x = 4 - 4x - 5
~Combine like terms on the left side
-1 - 4x = -1 - 4x
~Add 4x to both sides
-1 = -1
~Add 1 to both sides
0 = 0
Therefore, all real numbers are solutions.

18. A shelf holds fewer than 50 cans. If all of the
cans on this shelf were put into stacks of
five cans each, no cans would remain. If the
same cans were put into stacks of three cans
each, one can would remain. What is the
greatest number of cans that could be on
the shelf?
Answer:
40
Step-by-step explanation:
Given that the number of cans are fewer than 50.
Let the number of cans = [tex]x[/tex]
It is given that no cans remain if they are put in the stacks of five cans each.
i.e. number of cans are a multiple of 5.
Let us have a look at the numbers in decreasing order which are multiples of 5 and are lesser than 50.
45, 40, 35, 30, ......
Now, let us check the numbers one by one.
If [tex]x=[/tex] 45,
Now, they are placed on stacks of three each and one can remains.
So, the remainder when [tex]x[/tex] is divided by 3 will be 1.
But when 45 is divided by 3, remainder is 0.
Now, let us check next greatest number, which is 40.
When 40 is divided by 3, the remainder is 1.
Therefore, greater number of cans can be 40.

The per capita (per person) income from 1980 to 2010 can be modeled by
f(x) = 2000(X – 1980) + 10,000
where x is the year. Determine the year when the per capita income was $18,000.
The per capita income was $18,000 in the year N.
Answer:
X= 1984
Step-by-step explanation:
f(x) = 2000(X – 1980) + 10,000
Where,
f(x)= per capita income
x= year
Find x when f(x)= $18,000
f(x) = 2000(X – 1980) + 10,000
18,000 = 2000(X - 1980) + 10,000
18,000 = 2000X - 3,960,000 + 10,000
18,000 = 2000X - 3,950,000
Add 3,950,000 to both sides
18,000 + 3,950,000 = 2000X
3,968,000 = 2000X
Divide both sides by 2000
X= 3,968,000 / 2000
= 1984
X= 1984
Therefore, the per capita income was $18,000 in the year 1984
6x + 2 = 9x - 4 help me please
Answer:
x=2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
6x + 2 = 9x - 4
We want terms with x on the left side and numbers on the right side.
Subtract 9x from both sides.
6x - 9x + 2 = 9x - 9x - 4
-3x + 2 = -4
Subtract 2 from both sides.
-3x + 2 - 2 = -4 - 2
-3x = -6
Divide both sides by -3.
-3x/(-3) = -6/(-3)
x = 2

answer:
x=-2
Step-by-step explanation:
my suggestion for this problem and all problems like it would to turn everything into 6ths. 1/3 would become 2/6. and 2 would become 12/6. leave the negatives. now you'll add 2/6 to -12/6. which will equal 10/6. divide 10/6 by 5/6 and youll get -2. x=-2
Answer:
x = -2
Step-by-step explanation:
● (5/6)x - (1/3) = -2
Add (1/3) to both sides
● (5/6)x - (1/3) + (1/3) = -2 + (1/3)
-2 is (-6/3)
● (5/6)x = (-6/3) + (1/3)
● (5/6)x = -5/3
Move 5/6 to the other side and switch the places of 5 and 6
● x = (-5/3) × (6/5)
● x = -30/15
● x = -2

Complete question is;
A student artist randomly selected two media from among: charcoal sketches, pencil drawings, and oil paintings, and then submitted all of her works in that media for a gallery showing. Identify the kind of sample that is described.
Answer:
Cluster sample
Step-by-step explanation:
Looking at the question, we can see that the media has already been grouped into 3 parts namely charcoal sketches, pencil drawings, and oil paintings. It has already been grouped into multiple groups for easy selection or identification.
Now this type of grouping is synonymous with cluster sampling because cluster sampling is a probability sampling technique in which the researchers divide the population into multiple groups known as clusters for research and this question clearly shows that the media has been grouped.

Answer:
After 4 minutes
Step-by-step explanation:
Balloon 1
Initial position = 10 mRise rate = 15 m/minBalloon 2
Initial position = 150 mDrop rate = 20 m/minTime required for the balloons to meet = x
After x minutes the first balloon will be at position:
10 + 15xAnd the second balloon will be at position:
150 - 20xSince they meet after x minutes, their position must be same:
10 + 15x = 150 - 20x15x + 20x = 150 - 1035x = 140x = 140/35x = 4 minutesSo the balloons will meet after 4 minutes

2(a+5)=-2 Steps too please ❤️
Answer:
a=-6
Step-by-step explanation:
2(a+5)=-2 Step 1 distribute
2a+10=-2 Step 2 minus 10 on both sides
2a=-12 Step 3 divide but 2 on both sides
a=-6
Answer:
a=-6
Step-by-step explanation:
In order to solve for a, we must isolate a on one side of the equation.
[tex]2(a+5)=-2[/tex]
2 is being multiplied by (a+5). The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]2(a+5)/2=-2/2[/tex]
[tex](a+5)=-2/2[/tex]
[tex](a+5)=-1[/tex]
5 is being added to a. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
[tex]a+5-5=-1-5[/tex]
[tex]a=-1-5[/tex]
[tex]a=-6[/tex]
Let's check our solution. Plug -6 in for a and solve.
[tex]2(a+5)=-2[/tex]
[tex]2(-6+5)=-2[/tex]
[tex]2(-1)=-2[/tex]
[tex]-2=-2[/tex]
This checks out, so we know our solution is correct.
The solution to the equation 2(a+5)=-2 is a=-6
What is 5+x+11x=11x+11
Answer:
x = 6
Step-by-step explanation:
Solve for x:
11 x + x + 5 = 11 x + 11
Hint: | Add like terms in 11 x + x + 5.
x + 11 x = 12 x:
12 x + 5 = 11 x + 11
Hint: | Move terms with x to the left hand side.
Subtract 11 x from both sides:
(12 x - 11 x) + 5 = (11 x - 11 x) + 11
Hint: | Combine like terms in 12 x - 11 x.
12 x - 11 x = x:
x + 5 = (11 x - 11 x) + 11
Hint: | Look for the difference of two identical terms.
11 x - 11 x = 0:
x + 5 = 11
Hint: | Isolate terms with x to the left hand side.
Subtract 5 from both sides:
x + (5 - 5) = 11 - 5
Hint: | Look for the difference of two identical terms.
5 - 5 = 0:
x = 11 - 5
Hint: | Evaluate 11 - 5.
11 - 5 = 6:
Answer: x = 6
Answer:
x = 6
Step-by-step explanation:
5 + x + 11x = 11x + 11
5 + 12x = 11x + 11
5 + 1x = 11
1x = 6
x = 6

Solve for y. I REALLY NEED HELP ON THIS!! 2(3y+6x)=2(5y-2x)
Answer:
y = 4x
Step-by-step explanation:
2(3y + 6x) = 2(5y - 2x)
Divide both sides by 2.
3y + 6x = 5y - 2x
Subtract 5y from both sides. Add 2x to both sides.
-2y = -8x
Divide both sides by -2.
y = 4x
