Answer:
A) The correct inequality is: -18 < 53
B) The correct description is: Eduardo sent fewer text messages during May than April
Step-by-step explanation:
Month Number of message
April 53
May -18
A) The correct inequality is: -18 < 53
Reason:
We need to choose the correct inequality, negative number is less than positive number so the inequality will be -18 < 53
B) The correct description is: Eduardo sent fewer text messages during May than April
Reason:
Negative values shows that he has messaged under the allotted limit, while positive values shows the number of messages he was over the limit.

Solve 5x+2=20
Answer:
x = 18/5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
5x + 2 = 20
Step 2: Solve for x
Subtract 2 on both sides: 5x = 18Divide 5 on both sides: x = 18/5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(18/5) + 2 = 20Multiply: 18 + 2 = 20Add: 20 = 20Here we see that 20 does indeed equal 20.
∴ x = 18/5 is a solution to the equation.

Step-by-step explanation:
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]

carlon plans to evaporate a number of gallons of water from 90 gallons of a 15% salt solution to make a 25% salt solution. which equation can he use to find x, the number of gallons that should be evaporated? original (gallons) removed (gallons) new (gallons) amount of salt 13.5 0 amount of solution 90 x startfraction 13.5 over 90 minus x endfraction
The value of X for carlon evaporate is 36.
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Given that
Total amount of solution = 90
total amount of salt = 15 % of 90
= [tex]90 \times \frac{15}{100}[/tex]
= 13.5
Now removed X from the solution
Then, remaining solution is 90 - X
Percentage of salt in the remaining solution [tex]= \frac{salt}{remaining solution}[/tex]
Given that , % of salt in the remaining solution is equal to 25% then, Percentage of salt in the remaining solution
⇒ [tex]\frac{salt}{remaining solution}[/tex] = 25%
⇒ [tex]\frac{13.5}{90 - X} = \frac{25}{100}[/tex]
⇒1350 = 2250 - 25 x
⇒ 25 x = 2250 - 1350
⇒ 25 x = 900
⇒ x = [tex]\frac{900}{25}[/tex]
⇒ x =36

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

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

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).
