Jerry is taking care of a vacant lot in his neighborhood. There are approximately 64 thistle weeds m the local
He decided to try a homemade weed killer his grandmother suggested. Five weeks later, the thistles have
decreased by 75%. Approximately how many thistles are in the vacant lot now?
Answer:
16
Step-by-step explanation:
To be able to find the number of thistles that are in the vacant lot now using the information provided, you have to calculate the 75% of 64 and then, subtract that number from 64:
64*0.75=48
64-48=16
According to this, the answer is that there are 16 thistles in the vacant lot now.

Convert to Slope-Intercept Form to graph 4x+3y=9
Please show the two points
The line of the equation in the Slope-Intercept Form would be; y=-4/3x+3
How to get the slope-intercept form of a straight-line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as y = MX +c. To find the slope of a line, the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.
Given that 4x+3y=9
Thus, 4x+3y=9
Subtract 4x on both sides;
4x -4x + 3y = 9 -4x
Now divide by 3 on both sides
3y= -4x+9
Then we get;
y=-4/3x+3
Hence, the line of the equation in the Slope-Intercept Form would be; y=-4/3x+3

in a survey, 25 out of 200 students are planning to vote for Susie for class president. If there are 1,000 students voting, how many votes would Susie expect?
Answer:
125 votes
Step-by-step explanation:
Set up a proportion.
[tex]\frac{25}{200} =\frac{x}{1000}[/tex]
Cross-multiply. Solve for x.
[tex]25,000=200x\\25,000/200 = 200x/200\\125=x[/tex]

Answer:
500m
Step-by-step explanation:
This question is really asking for the perimeter of the rectangle. The two of the longest sides is 14 units, the other 2 are 11 units. 14 + 14 + 11 + 11 = 50 units/ 1 unit is 10m, so 50 by 10 is 500, 500 meters.

Answer:
w = -13
Step-by-step explanation:
Since BC bisects <ACD, then <ACB = <BCD.
We know that those two angles must equal 108 because 180-72=108.
Half of 108 is 54.
<BCD is the same as the same as the angle that equals 2w+80, so
2w+80=54
2w=54-80
2w=-26
w=-13
Find the value of X. Then find the measure of each labeled angle.
Answer:
x=118, top right angle is 118, bottom right is 62, bottom left is 90, and top left is 90
Step-by-step explanation:
1. since a quadrilateral's andles sum up to 360, these must sum up to 360
2. since the two sides (top and bottom) are parallel, the bottom left and top left angles add up to 180 (it's a conjecture)
3. this means that (x-56) + x+ 90 + (180-90)=360
4. simplify: 2x + 124 = 360
5. solve: x= 118
6. this means top right angle is 118, bottom right is 62, bottom left is 90, and top left is 180-90=90
Why can you use Linear Pairs and Vertical Angles to prove lines are parallel?
Answer:
The reason why linear pairs and vertical angles are used to prove lines are parallel is because they area transversal drawn through the parallel lines will form angles on each of the two parallel lines including;
1) Supplementary linear pairs and
2) Vertical angles
3) Alternate angles
Given that either;
a) The corresponding angles that form the linear pairs are congruent
b) The corresponding vertically opposite angles are congruent
c) The corresponding alternate angles are congruent, we have;
The two lines are said to be parallel.

Please let me know WHY you choose your answers please, I want to understand this more.
Answer:
A. no
B. yes
C. yes
Step-by-step explanation:
A. not enough information is given other than the fact that ∠E ≡ ∠B (45°)
B. SAS (side angle side). To make ∠ABC into ∠DEF, you need to multiple the side lengths in ∠ABC by 3/2
12/x = 8 .... rearrange .... x = 3/2
C. AA (angle angle). ∠A is congruent to ∠Y and this is given by those two lines. ∠B is congruent to∠Z and this given because it has one line. This means that the other angle (C and X) would be congruent.

George’s age is three times that of his brother. When you add George’s age to his brother’s, you get 24. How old is each brother?
a) Write an equation that represents the situation. Explain any variable used.
b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
G=18
Step-by-step explanation:
George-G
1/3G+G=24
4/3G=24
3/4*4/3G=24*3/4
G=18
George will be 18 years old there we can find his brothers age by dividing it by three thus 18/3=6
Answer:
George is 18 and his brother is 6
Step-by-step explanation:
let the brother's age be n then George's age is 3n ( 3 times his brother's age )
n + 3n = 24 ( sum of their ages )
4n = 24 ( divide both sides by 4 )
n = 6
and 3n = 3 × 6 = 18
George is 18 years old and his brother is 6 years old.

A car has a 16-gallon fuel tank. When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas
tank, the driver got on a highway and drove for a while.How many miles has the car traveled if it has 10 gallons of gas left in the tank?
and write an equation that represents the relationship between the distance the car has traveled in mikes, d, and the amount of gas left in the tank in gallons, x
Answer:d=(16-x)30
Step-by-step explanation:
The car traveled 600 miles if it has 10 gallons of gas left in the tank.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.
To determine the equation that represents the relationship between the distance traveled by car and the amount of gas left in the tank.
Let the distance traveled by car would be d miles,
and the amount of gas left in the tank would be x gallons
Since the car had a 16-gallon fuel tank
So the amount of gas left in the tank would be 16 - x
When driven on a highway, it has a gas mileage of 30 miles per gallon.
To find the equation of the distance we have to calculate the product of gas left in the car and the mileage of the car.
So the required equation as:
⇒ d = (16-x)30.
If it has 10 gallons of gas left in the tank
Substitute x = 10 in the above equation, we get
⇒ d = (16-10)30.
⇒ d = (20)30.
⇒ d = 600.
Therefore, the car traveled 600 miles if it has 10 gallons of gas left in the tank.
