Step 1: Define inequality
9p - 9 < 4p - 2
Step 2: Solve for p
Subtract 4p on both sides: 5p - 9 < -2Add 9 on both sides: 5p < 7Divide both sides by 5: p < 7/5Here, we see that any value p smaller than 7/5 will work as a solution.

It wouldn't be A since 5 - 1 you would get 4 hundred not 4 tens. It wouldnt be B because 9 - 6 you would get 3 ones not 3 hundreds and 5-1 you would get 4 hundreds not 4 ones. It wouldnt be D because 9-6 would be 3 ones not 3 tens. Hope I helped ! Good luck !
Y=2x and 5x-y=9 substitution
Answer:
3,6
Step-by-step explanation:
Plug 2x(y) into 5x -y = 9
5x -2x = 9
Add like terms.
3x = 9
Divide both sides by 3.
x = 3
Now, in order to find y, plug 3(x) into y = 2x
y = 2(3)
y = 6
The solution of system of equation is x=3 and y=6.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y=2x .....................(1)
5x-y=9...............(2)
Now substitute the value of y in equation (2), we get
5x - 2x = 9
3x = 9
Divide both side by 3.
x= 3
and, y= 2x = 6

Jimmy walks to his school every morning. He leaves home everyday at the same time. And the school starts at the same time everyday at 8 am. If he walks at 40 meters per minute, he will reach his school 5 minutes late. If he walks at 60 meters per minute, he will reach his school 3 minutes before the bell rings.
Answer: The bell rins at 8:19 AM, and the distance between Jimmy's house and the school is 960 meters.
Step-by-step explanation:
Let's define the variables:
T = Number of minutes after 8 AM such that the school's bell sounds.
D = Distance between jimmy's house and the school, in meters
And remember the relation:
Distance = Speed*Time.
We know that:
"If he walks at 40 meters per minute, he will reach his school 5 minutes late."
D = (T + 5)*40
"If he walks at 60 meters per minute, he will reach his school 3 minutes before the bell rings."
D = (T - 3)*60
Then we have a system of equations:
D = (T + 5)*40
D = (T - 3)*60
We can take the quotient of these two equations and get:
D/D = ((T + 5)*40 )/((T - 3)*60)
1 = (4/6)*(T + 5)/(T - 3)
Now let's solve this for T.
6/4 = (T + 5)/(T - 3)
(6/4)*T - (6/4)*3 = T + 5
(6/4)*T - T = 5 + (6/4)*3
T*(2/4) = 5 + 18/4 = 5 + 9/2
T = (4/2)*(5 + 9/2) = 19
Then the bell sounds 19 minutes after 8AM, at 8:19 AM
And with this, we can find the distance D:
D = (T + 5)*40 = (19 + 5)*40 = 960
The distance between Jimmy's house and the school is 960 meters.
What are the solutions to this quadric equation? -2x^2 + x + 4 = 0
Answer:
(1-[tex]\sqrt{33}[/tex])/4 and (1+[tex]\sqrt{33}[/tex])/4
Step-by-step explanation:
-2x^2 + x + 4 = 0
use quadratic formula x= (-b±[tex]\sqrt{b^{2} -4ac}[/tex] ) / 2a
a=-2
b=1
c=4
x= (-1±[tex]\sqrt{1^{2} -4(-2)(4)}[/tex] ) / 2(-2)
x=(-1±[tex]\sqrt{33}[/tex] ) / -4
x=(1 -[tex]\sqrt{33}[/tex]) / 4 and (1 +[tex]\sqrt{33}[/tex]) / 4

A line passes through the point (-4,9) and has a slope of
-3/2
Write an equation in point-slope form for this line.
Answer: y - 9 = (-3/2) (x - (-4))
Step-by-step explanation:
We can use the formula y-y1 = m(x-x1)
Where (x1,y1) are (-4, 9) and m = -3/2. Plug in the values and we get
y - 9 = (-3/2) (x - (-4))
In Lixue's garden, the green pepper plants grew 5 inches in 34 month. At this rate, how many feet can they grow in one month? (Let 5 inches = 512 feet)
Answer:
22/3 feet
Step-by-step explanation:
In Lixue's garden, the green pepper plants grew 5 inches in 3/4 month.
We need to find how many feet can they grow in one month.
Let 5 inches = 5 1/2 feet
It means,
The growth in 3/4 month = 5 inches = 11/2 feet
Growth in 1 month = [tex]\dfrac{\dfrac{11}{2}}{\dfrac{3}{4}}=\dfrac{22}{3}[/tex] feet
So, it will grow 22/3 feet in a month.

Liberty Center Middle School has 1,200 students. In Sophia’s class, 3 out of 4 students borrowed library books. Based on these results, how many students at the school would you expect to borrow library books?
Answer:
We expect 900 students to borrow library books
Step-by-step explanation:
Proportions
If two variables are proportional, then one of them can be obtained as the other times a fixed number.
If x and y are proportional, then:
y=k.x
Where k is the constant of proportionality
The value of k can be obtained by dividing y/x.
That division, also called ratio gives us the proportion to be applied to future calculations.
In Sophia's class, 3 out of 4 students borrowed library books.
This gives us a proportion ratio of 3/4.
If we apply that same proportion to the rest of the Liberty Center Middle School, with 1,200 students, then, we expect to have
3 / 4 * 1200 = 900 students borrowing library books.
We expect 900 students to borrow library books

!!HELP: 20 POINTS!!At the end of a snow storm, Jace saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of snow on Jace's lawn, in inches, can be modeled by the equation S=15-1.5t,where t is the time, in hours, after the snow stopped falling. What is the y-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.
The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.
Step-by-step explanation:
the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.
The rate of melting is 1.5inches per hour.
At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start
At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.
