The number line is attached in the solution.
What is number line?In math, a number line is a horizontal straight line with numbers placed at equal distances from each other along that line.
A number line is a pictorial representation of numbers on a straight line. It's a reference for comparing and ordering numbers.
Given is an expression, -4-(-1), we need to plot its solution on the number line,
So,
-4-(-1)
Opening the brackets,
= -4+1 [∵ (-) × (-) = +]
= -3
Plotting -3 in the number line, it will be put 3 units left from zero in the number line,
We put negatives number on the left side and the positive numbers on the right side of zero, in the number line,
For example, we are asked to put 7 in the number line, we will count 7 units to the right of zero in the number line, and suppose if we are asked to plot -6, then we will count 6 units to the left of zero in the number line.
The number line is extended from -∞ to +∞

Answer:
A
Step-by-step explanation:
Aruba has the lowest population
It would be 'Aruba has the least population'
Bolivia has an exponet of 7, 7 zeros while Aruba has 5
The Philippines has a population that is a multiple of Aruba, as long as it's not 1 or less it's going to be greater then Aruba
Therefore since both would have more, your true statement would be the first one
what is the width of a rectangle with length 25in and area of 375^{2}
Explanation:
I'm assuming you meant to say the area is 375 in^2, aka 375 square inches.
If so, then,
area of rectangle = length*width
A = L*W
A/L = W
W = A/L
W = 375/25
W = 15 inches
As a check,
A = L*W = 25*15 = 375 which helps confirm the answer.

Answer:
3-gallon jug of water for $10.92, is the better buy
Step-by-step explanation:
First let's do the 3 gallon jug -
We need to find the unit rate (The cost per gallon/quart)
$10.92 / 3 = $3.64
$8.64 / 8 = $1.08
1 Gallon = 4 Quarts, therefore the 3-gallon jug of water is the better buy.

You are installing a fence around your yard. In the figure,
your yard is rectangle ABCD. Each unit in the coordinate
plane represents 10 feet.
a. What is the perimeter of your entire yard
b. You consider only installing a fence around your backyard represented by rectangle ABEF what is the perimeter of your backyard?
c. The cost of fencing is $50 for each 6 foot section how much do you say by only installing a fence in the backyard?
Perimeter of a shape can be determined by the sum of its individual sides. Thus, the answers to the given questions are:
(a) 360 feet
(b) 240 feet
(c) $1000.0
Perimeter can simply be defined as the sum of all sides of a given figure or shape. Thus, the solutions required can be determined as follows:
(a) Side AB = CA = (7 - 1) x 10 feet
= 6 x 10 feet
= 60 feet
Side AD = BC = 13 - 1
= 12 x 10 feet
= 120 feet
The perimeter of the entire yard = 60 + 120 + 60 + 120
= 360
Perimeter of the entire yard = 360 feet
(b) Side AB = EF = 60 feet
Side FA = BE = (7 -1) x 10 feet
= 60 feet
So that,
The perimeter of the backyard = 60 feet x 4
= 240
Perimeter of the backyard = 240 feet
(c) The cost of installing a fence in the entire yard = [tex]\frac{360}{6}[/tex] x $50
= $3000.0
The cost of installing a fence in the back yard = [tex]\frac{240}{6}[/tex] x $50
= $2000.0
The amount saved by only installing a fence in the back yard = $3000.0 - $2000.0
= $1000.0
Thus, the amount saved by only installing a fence in the back yard is $1000.0

How many ounces of a 15% alcohol solution must be mixed with 4 ounces of a 20% alcohol solution to make a 17% alcohol solution?
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
Answer:
Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution
Step-by-step explanation:
Let x ounces of 11% alcohol must be mixed with the 2 ounces of 20% alcohol.
The amount of alcohol in 4 ounces solution is= ounces
= 0.8 ounces
The amount of alcohol in x ounces solution is= ounces
= 0.11 x ounces
Total amount of alcohol is = (4+x) ounces
According to the problem,
Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution

Step-by-step explanation:
6x-19=3x+32(vertically opposite angles)
6x-19-3x=32
3x =32+19
3x=51
x=17 degrees
when we substitute x in these:
6x-19=83
3x+32=83
if 1=y
83+83+Y+Y=360(points around a point is 360 degrees)
166+2Y =360
2Y =360-166
2Y=194
Y=97
Therefore 1=97 degrees

a) No solution
b) x=0
c) x=1
d) x=-1.25
Answer:
-1.25 =x
Step-by-step explanation:
-5x + 10 = -13x
Add 5x to each side
-5x + 10+5x = -13x+5x
10 = -8x
