Answer:
Since 10% like neither, then 90% must like tea(T), coffee(C) or both(B). So what % like both? That % would have to be deducted from both the tea and coffee likers to arrive at tea only (TO), coffee only (CO) and those liking both and the three would have to sum to 90%, since 10% like neither. So whatever % the 120 represents it must be deducted from both the tea and coffee likers. I don’t know how to add graphics but in equation form
50-x + 70-x + x + 10 = 100, 130-x = 100, -x = -30, X = 30%,
120/30% = 400, 50%(T)-30%(B)=20%(TO) or 80, 70%-30%=40% or 160, 30% or 120, and 10% or 40
80+160+120+40=400
Answer:
Step-by-step explanation:
50% 70% 10%
like tea like coffee don't like both
100%-10% =90%
like coffee,tea or both
50% + 70% =120% - 90% = 30%
like tea + like coffee = - = like both
LIKE BOTH 30%=`120
means 1%=4
100%=400

Solve -3(x-2)=2(x-7) and write a reason for each step
Answer:
4=x
Step-by-step explanation:
-3(x-2)=2(x-7)
Distribute -3 and 2.
-3x+6=2x-14
Add 3x to both sides of the equation.
6=5x-14
Add 14 to both sides of the equation.
20=5x
Divide 5 from both sides of the equation.
4=x
Hope this helps :)
Answer:
x=5
Step-by-step explanation:
Our equation is
-3(x-2)=2(x-7)
First we will distribute -3 and 2, because in math when we have a number being multiplied into parenthesis we multiply both things inside of it
Our equation is now
-3x+6=2x-14
Next we subtract 6 from both sides because we want x to be on only one side
-3x=2x-20
Next we subtract 2x from both sides because we want x to equal something exactly
-5x=-20
Now we divide -5 from both sides because we only want x
x=5

Graph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it.
y=2x+1
y=x-2
one solution; (–3, –5)
infinitely many
no solution
one solution; (–5, –3)
Answer:
y=11-2x x + y =15
4x − y=7 and 2x − y=15 all have one solution
x=12 − 3y 2x + y=7
3x + 9y=24 and -4x=2y + 14 have no solution
you can just put the rest in infinite solutions

A cyclist travels 9.6 km in 30 minutes. What is his average speed in km/h?
Answer:
[tex]\frac{95}{5} \frac{km}{hour}= 19.2 km/hour[/tex]
Step-by-step explanation:
Average speed = distance/time
Average speed = [tex]\frac{9.6}{30} \frac{km}{min}[/tex] ; multiply by 60min/1hour
Average speed = [tex]\frac{95}{5} \frac{km}{hour}= 19.2 km/hour[/tex]

The cost of a blue balloon is 4 times the cost of a yellow balloon. Rashmi spent₹ 910 in buying both blue and yellow balloons, find the cost of a blue balloon?
The cost of the blue balloon is ₹728.
let
the price of the yellow balloon = x
cost of the blue balloon = 4x
Total amount spent = ₹ 910
Therefore,
4x + x = 910
5x = 910
divide both sides by 5
5x / 5 = 910 / 5
x = 182
cost of the blue balloon = 4x = 4(182) = ₹728

What is algebraic equation?Algebraic equation, statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root.
Examples: (y²x² + 2xy – y)/(x – 1) = 12.
Given, equation
[tex]\frac{4}{5}(x- \frac{3}{10} )[/tex] = [tex]-2\frac{1}{4}[/tex]
⇒4/5[(10x-3)/10] = -9/4
⇒2/5[(10x-3)/5] = -9/4
⇒(20x-6)/25 = -9/4
⇒80x - 24 = -225
⇒80x = -225 + 24
⇒x = -201/80
⇒x = -2.5125

What is the equation of the line that passes through points (10,6) and (2,2) ?
Answer:
y = (1/2)x + 1
Step-by-step explanation:
y = mx + b
m = slope = (y2 - y1)/(x2 - x1) = (6 - 2)/(10 - 2) = 4/8 = 1/2
y = (1/2)x + b
Use point (2, 2) to find b.
2 = (1/2)(2) + b
2 = 1 + b
b = 1
Equation: y = (1/2)x + 1
