Describe in detail how you would create a number line with the following points: 4, 1.25, the opposite of 3, and – (–2fraction of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first. brainleist for right answere if u dont answer propoly i will report!
Answer:
Given : points 4 , 1 ,25 , opposite of 3 , -1/2
To Find : draw on Number Line
Solution :
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
1 : Draw a line and mark some points at equal distance on it as shown in the figure below Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on
2. Go 4 unit on right sides from Zero to show 4
3. Go 3 units on Left from zero to show opposite of 3
4. Divide number line between 1 & 2 in 4 Equal parts and go 1 part right of 1
5. Divide number line between 0 & -1 in 2 Equal parts and go 1 part left of 0

A system of equation is shown.
5x+2y=245
y=x+6
Enter a numeric value to complete the solution of the system.
Answer:
y = 245 / 7, x = 29
Step-by-step explanation:
make both into ax + by = c format which is
Math:
5x + 2y = 245
-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.
[(Side Note) if both were positive then you would need to do
EX: - 5 (- x + y = 6)]
Continued:
7y = 275 ==> 7y/7 = 245/7
y = 245 / 7
Plug it in the most convenient one which has the equation y = x + 6
and tweak it a bit
x = y - 6
x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7
x = 203 / 7 ==> 29

2. Write an expression for the number of scoops Zack needs to fill both feeders
3. Evaluate the expression to find the number of scoops Zack needs. Show your work
Answer:
1.) 5
2.) 0.25x=5
3.) 20
Step-by-step explanation:
1.) 2.5 (same as 2 1/2) x2 ("both bird feeders")= 5 cups needed
2.) 0.25x=5 x= amount of cups needed (0.25 is the same as 1/4)
3.) 5÷0.25= 20
Answer:
1.) 5
2.) 0.25x=5
3.) 20
(BRAINLIEST IF CORRECT ANSWER) When you roast coffee, it loses 12% of its weight. How much fresh coffee do you need to order to get 14 2/25 lb of roasted coffee?
==========================================================
Explanation:
14 & 2/25 = 14 + 2/25 = 14 + 0.08 = 14.08
The mixed number 14 & 2/25 is the same as the decimal 14.08
The goal is to end up with 14.08 pounds of coffee.
Let x be the starting amount of coffee, in pounds. It will decrease to 14.08 pounds.
We start with x and decrease by 12%. So we are computing this expression
x - 12% of x = 1x - 0.12x = (1-0.12)x = 0.88x = 88% of x
We can see that if we lose 12%, we keep the remaining 88%
The 0.88x is the final weight.
Set 0.88x equal to the goal of 14.08 and solve for x.
0.88x = 14.08
x = (14.08)/(0.88)
x = 16
You'll need to start off with 16 pounds of coffee if you want to end up with 14.08 pounds after losing that 12%
-------------------
Check:
12% of 16 = 0.12*16 = 1.92
16 - 1.92 = 14.08
The answer is confirmed.
You need to order approximately 4.15 pounds of fresh coffee to get 14 2/25 pounds of roasted coffee after accounting for the 12% weight loss during roasting.
To find out how much fresh coffee you need to order to get 14 2/25 lb of roasted coffee, you'll need to account for the 12% weight loss during the roasting process.
Let's assume "x" represents the amount of fresh coffee (in pounds) you need to order. When this fresh coffee is roasted, it will lose 12% of its weight, leaving you with 100% - 12% = 88% of the original weight as roasted coffee.
Now, set up a proportion to find "x":
(88/100) * x = 14 2/25 lb
First, convert the mixed number 14 2/25 to an improper fraction. It becomes (364/25) lb.
Now, solve the equation for "x":
(88/100) * x = 364/25
To eliminate the fraction, you can multiply both sides of the equation by the reciprocal of (88/100), which is (100/88):
x = (364/25) * (100/88)
Now, simplify the expression:
x = 4.15 lb (rounded to two decimal places)
