Which equation can be used to solve for x in the following diagram?
Answer:
A
Step-by-step explanation:
the answer is option A as
6x + 12x = 90
so 6x + 12x + 90 = 90 + 90 + 180
X/[] is a fraction if you add 1 to the numerator and subtract 1 from the denominator the fraction will become 4/5
The fraction is [tex]\frac{3}{5}[/tex]
Let's take the fraction as [tex]\frac{a}{b}[/tex]
According to the first statement,
If we add 1 to the numerator and subtract 1 from the denominator a fraction reduces to 1.
[tex]\frac{a + 1}{b - 1}[/tex] = 1
a + 1 = b -1
a + 2 = b
b = a + 2........(1)
According to the second statement
If we only add 1 to the denominators, it becomes 1/2.
[tex]\frac{a}{b+1}[/tex] = 1/2
2a = b + 1
b = 2z -1 .........(2)
Equating both the equation (1) and (2)
2a - 1 = a + 2
2a - a = 2 + 1
a = 3
Now substitute the value of a in equation (1)
b = 3 + 2
= 5
Therefore the fraction is [tex]\frac{a}{b}[/tex] = [tex]\frac{3}{5}[/tex]

a -foot piece of string is cut into two pieces so that the longer piece is longer than twice the shorter piece. find the lengths of both pieces.
The length of longer piece is 2L/3 and shorter piece is L/3;
Let the length of string be 'L';
Let the longer piece be 'L₁' and shorter piece be 'L₂';
L₁ + L₂ = L; -(i)
According to question;
L₁ = 2L₂; -(ii)
Using (ii) in (i);
3L₂ = L;
L₂ = L/3;
L₁ = 2L/3;

What slope passes through the points (-1,5) and (3,-7) ?
Explain how to determine if you have a direct variation or proportional relationship
given a graph
Answer:
straight line that passes through the origin
Step-by-step explanation:
Two variables are said to have a direct variation or proportional relationship if it can be represented by y = kx, where k is a constant.
Comparing this with the equation of a straight line y = mx + b, where m is the slope of the line and b is the y intercept (value of y when x = 0), We can tell if the say that the graph of a direct variation or proportional relationship is a straight line with no y intercept (b = 0, that is it passes through the origin).

Under certain conditions the pressure of a gas varies directly with the temperature. When the pressure is 900 psi, the temperature is 350. What is the pressure when the temperature is 70?
Answer:
180psi
Step-by-step explanation:
Step one:
given data
P1= 900 psi
T1= 350°C
P2=?
T2=70°C
Required
The final pressure P2
Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up
Applying the expression
P1/T1= P2/T2
substitute:
900/350= P2/70
2.57=P2/70
cross multiply
P2= 2.57*70
P2=180psi
Evaluate f(x) = 5* when x = -3.

A jar contains 3 blue marbles, 7 red marbles, and 5 green marbles. you pick one without looking. whats the probability that the marble will not be red?
Probability of not picking up a red marble = 8/15
No of red marbles = 7
No of green marbles = 5
No of blue marbles = 3
Total sample space = 3+7+5 = 15 marbles
Probability of picking out blue marble = 3/15
Probability of picking out red marbles = 7/15
Probability of picking out green marbles = 5/15
Probability of not picking up a red marble = 1 - 7/15 = 8/15
