Some people attended a small concert last Saturday. 70 of those people sat in the balcony
of the theater. This was 35% of the people who attended. How many people were at the
concert?
Answer:
200
Step-by-step explanation:
If 'a' is the total attendance, the given relation is ...
70 = 0.35a . . . . . . 70 is 35% of attendance
Dividing by the coefficient of 'a', we find the attendance was ...
70/0.35 = a = 200
200 people were at the concert.

Rahmi bought 1 pair of jeans and 2 T-shirts. How much did rahmi spend? Write equations to solve. Use a letter to represent the unknown quantity
Answer:
1x + 2y = (The answer/money spent)
Step-by-step explanation:
in a survey of 200 workers, 130 drink coca-cola and 100 drink fanta. how many workers drink at least one of coca-cola and fanta.
The number of workers that drink at least one of coca-cola and fanta is = 30.
Calculation using Venn diagramThe total number of workers under survey = 200
The number of workers that drink only coca cola = 130 - X
The number of workers that drink fanta = 100 - X
The number of workers that drank at least one drink = X
To calculate for x;
130 - X + X + 100 - X = 200
Being like terms together,
-X = 200 - 130 -100
-X = 200 - 230
-X = - 30
X = 30
Therefore, the number of workers that drink at least one of coca-cola and fanta is = 30

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?
The test contains 4 three-point questions and 20 five-point questions.
The test contains 10 three-point questions and 14 five-point questions.
The test contains 14 three-point questions and 10 five-point questions.
The test contains 20 three-point questions and 8 five-point questions.
Answer:
10 three-point questions and 14 five-point questions.
Step-by-step explanation:
x+y = 24
3x+5y = 100
We can solve this system of equations using elimination. In order to do this, let's first multiply the first equation by 3...
3x+3y=72
3x+5y=100
Now, subtract the first equation from the second equation...
2y=28
Divide both sides by 2
y=14
Plug this back into any of the equations to solve for x...
x+14=24
x=10
There were 10 three-point questions and 14 five-point questions

Determine the slope and the y-intercept of the following equation.
2x + 7y = 8
Answer:
the slope = -2/7
the y-intercept = 8/7
Step-by-step explanation:
Rewrite the equation to a slope-intercept form:
7y = 8 - 2x
7y = -2x + 8
[tex]y=-\frac{2}{7}x+\frac{8}{7}[/tex]
so the slope = -2/7
the y-intercept = 8/7

What’s the length of this missing leg?
Answer:
b = 4.5 mm
Step-by-step explanation:
using Pythagoras theorem:
a² + b² = c²
4² + b² = 6²
b² = 6² - 4²
b² = 36 - 16
b² = 20
b = √20
b = 4.5
Pythagoras theorem:
a² + b² = c²
4² + b² = 6²
b² = 6² - 4²
b² = 36 - 16
b² = 20
b = [tex] \sqrt{20}[/tex]
b = 4.5

Step-by-step explanation:
From this picture that I sent, you can see that the red line would be solid because it is less than or greater than, which the blue one isn't solid because it is just greater than. I felt like it would've been easier to explain it with an image than with words.
Draw a model that shows 3 items being divided equally for 4 people.
How much will each person have?
FRACTION MODEL PLEASE PUT PICTURE TOO
Answer: Each person will have 3/4 of all the items
Step-by-step explanation: Each person will get 1/4 of each item. Because there are three items in all, each person will get 3/4 of all the items.
Answer:
Every person will get 3/4 of an item
Step-by-step explanation:
3 items split between 4 people is simply 3/4 item per person. Draw a shape like a circle, square, or rectangle 3 times and split each into 4 equal pieces. There should now be 12 total parts which 3 will be given to each person. Write a unique names or labels (like a letter or number) on different pieces for 4 different letters or symbols.
Not the best artist but model should look something like the image.

LCM of 28 and 8??
Answer:
LCM= 56
Step-by-step explanation:
Multiplies of 8- 8, 16, 24, 32, 40, 48, 56, 64, 72
Multiplies of 28- 28, 56, 84, 112
Then, you look at the numbers that are the same in both. In some cases, there will be more than one that shows up (but not in this case) and all you have to do is find the least common multiple or LCM.

The equation y = 1.55x + 110,419 approximates the total cost, in dollars, of raising a child in the United States from birth to 17 years, given the household’s annual income, x.
Approximately how much would it cost to raise a child from birth to 17 years in a household with an annual income of $64,000?
A )$209,619
B )$186,302
C $164,219
d) $99,200
Answer:
A) $209,619
Step-by-step explanation:
y = 1.55x + 110,419
y = 1.55(64,000) + 110,419
y = 99,200 + 110,419
y = 209,619
Answer:
A) $209,619y = 1.55x + 110,419
y = 1.55 (64,000) + 110,419
y = 99,220 + 110,419
y = 209,619

CAN SOMEONE HELP ME WITH THIS?? ILL GIVE YOU BRAINLIEST
Answer:
24 units
Step-by-step explanation:
Note that BC is one side of the square. (Vertices are in order ABCD)
So, as a square has four equal sides, the perimeter is 4 times the length of BC.
We're given B is at (-2, 5) and C is at (4, 5). So, BC = 6 units.
So, the perimeter of ABCD is 6 * 4 = 24 units.
What is an equation of the line that passes through the points (-2, 7) and (1, -8)
1. using point-slope formula:
(y2-y1)/(x2-x1)=
(-8-7)/(1-(-2))=

At a horseback riding competition in the Olympics, each rider receives a score from 2 judges’
scores. Maddy was one of the riders in the competition. If one judge awarded Maddy a score
of 87, and Maddy’s final score was 84.5, what score did the other judge award Maddy?
Answer: 82
Step-by-step explanation:
Let the score that the other judge gave Maddy be M
We get the equation
(87+M)/2 = 84.5
87+M = 169
M = 82
