What does Regroup Mean?In math, regrouping can be defined as the process of making groups of tens when carrying out operations like addition and subtraction with two-digit numbers or larger. To regroup means to rearrange groups in place value to carry out an operation. We use regrouping in subtraction, when digits in the minuend are smaller than the digits in the same place in the subtrahend.
Given here, 3 tenths and 24 hundredths after regrouping we get
(3 tenths + 24 hundreths) = 0.54

Two shipping companies charge different amounts to ship a package. Company A charges a fee of $6.50 and $0.35 for each pound. Company B charges a fee of $7.25 and $0.25 for each pound. Write an equation that could be used to find p, the number of pounds each package would have to weigh for the total cost of shipping the packages to be the same.
Answers
The number of pounds each package would have to weigh for the total cost of shipping the packages to be the same will be 7.50 pounds.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The cost to transport an item varies between two shipping providers. The price charged by Company A is $6.50 plus $0.35 per pound. Charges from Company B are $7.25 plus $0.25 per pound.
Let 'p' be the number of pounds and 'T' be the total cost of shipping. Then the equations are given as,
T = 0.35p + 6.50
T = 0.25p + 7.25
If the total cost of shipping the packages is to be the same. Then the number of pounds is given as,
0.35p + 6.50 = 0.25p + 7.25
0.35p - 0.25p = 7.25 - 6.50
0.10p = 0.75
p = 7.50 pounds
The number of pounds each package would have to weigh for the total cost of shipping the packages to be the same will be 7.50 pounds.

9. b if a=4
10. b if a=4.5
11. b if a= 4.8
12. b if a=3.6
13. b if a=6
Answers
Answer:
see explanation
Step-by-step explanation:
given the equation
a = [tex]\frac{k}{b}[/tex]
to find k use the given condition a = 8 when b = 6 , then
8 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 to clear the fraction )
48 = k
a = [tex]\frac{48}{b}[/tex] ← equation of variation
2
if b = 3
a = [tex]\frac{48}{3}[/tex] = 16
3
if b = 4
a = [tex]\frac{48}{4}[/tex] = 12
4
if b = 12
a = [tex]\frac{48}{12}[/tex] = 4
5
if b = 1.5
a = [tex]\frac{48}{1.5}[/tex] = 32
6
if b = 3.6
a = [tex]\frac{48}{3.6}[/tex] = 13.3333.. = 13 [tex]\frac{1}{3}[/tex]
7
if b = 4.8
a = [tex]\frac{48}{4.8}[/tex] = 10
for the remaining questions, rearrange the equation with b as the subject
a = [tex]\frac{48}{b}[/tex] ( multiply both sides by b )
ab = 48 ( divide both sides by a )
b = [tex]\frac{48}{a}[/tex]
8
if a = 3
b = [tex]\frac{48}{3}[/tex] = 12
9
if a = 4
b = [tex]\frac{48}{4}[/tex] = 12
10
if a = 4.5
b = [tex]\frac{48}{4.5}[/tex] = 10.666... = 10 [tex]\frac{2}{3}[/tex]
11
if a = 4.8
b = [tex]\frac{48}{4.8}[/tex] = 10
12
if a = 3.6
b = [tex]\frac{48}{3.6}[/tex] = 13.333... = 13 [tex]\frac{1}{3}[/tex]
13
if a = 6
b = [tex]\frac{48}{6}[/tex] = 8

Answers
The simplest form is 15z+ 15x²
How to simplify the given expression ?In algebra, a triangle-shaped grouping of integers known as Pascal's triangle provides the coefficients for the expansion of any binomial formula, such as (x + y)n. Although it is much older, it bears the name of the French mathematician Blaise Pascal from the 17th century.
Because it has so many patterns that can be used to greatly simplify complex calculations, Pascal's triangle is significant.
Given,
(5z+5 x²)3
15z+15x² by simplifying,
3(5z+5 x²)
apply the distributive formula :a (b + c) =ab + ac
3(5z+5 x²) = 5x+3 * 5x²
By simplifying 3 5z+3 , 5x², 15z+15x²

The actual dimensions are 9.75 feet and 7.5 feet. The area will be 73.125 square feet.
What is the scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). The scale factor is defined as the proportion of the new image's size to that of the previous image.
Here the scale factor for the given image is 2 inch = 3 ft.
The measure of the actual dimensions will be calculated as,
2 in = 3 ft

If there are [tex]2\pi[/tex] radians and [tex]360 \textdegree[/tex] in one full rotation and an angle has a measure of [tex]2.1 radians[/tex] then the angle is 33.4 percent of a full rotation , and the measure of the angle in degrees is [tex]120.2\textdegree[/tex] .
we know that in 1 full rotation , the radians is 2π ;

y=x²-3x-4

Answers
Answer:
I have no idea tbh I need help with this too
Step-by-step explanation:
PLEASE HELP!!!!!!!!!!!!!!!
Solving second equation in terms of y:
Add x to both sides:
y=-4+x
Use the commutative property if addition to rearrange the Rayo to y=mx+b form:
y=x-4
So, we have a quadratic function and a linear equation.
Pay close attention to the equations below:
y=x²-3x-4
y=x-4
Both equations are equal to y, and because a system of equation solves for interception points on the two functions (the point where the two functions contain the same x and y-coordinates), the y-coordinates must be equal to each other. Therefore, the equations can be set equal to each other:
(x-4)=x²-3x-4
Factor the quadratic:
(x-4)=(x+1)(x-4)
Now, let’s solve for x:
Divide both sides by (x-4):
(x-4)/(x-4)=[(x+1)(x-4)]/(x-4)
Simplify:
1=(x+1)
Subtract 1 to both sides:
1-1=x
0=x
Apply the symmetric property:
x=0
Now that we know the two equations intercept at x=0, let’s plug 0 back into “y” to find its value. Since both equations are set equal, plug x=0 in for either one.
y=(0)-4
y=-4
So, a solution set is (0, -4) and (4, 0)

The length of a rectangle is 7cm more than twice the width. When just the width is tripled, the perimeter of the resulting rectangle is 74cm. What are the original dimensions of the rectangle?
Answers
Answer:
Length = 27cm
Width = 10cm
Step-by-step explanation:
Let the length of the rectangle be x
Let the width be y
If the length of a rectangle is 7cm more than twice the width, then;
x = 2y + 7
Since P = 2(x+y)
P = 2(2y+7+y)
P = 2(3y+7)
P = 6y+14
If the width is tripled, P = 74
74 = 6y+14
6y = 74-14
6y = 60
y = 10
Since x = 2y+ 7
x = 2(10) + 7
x= 20+7
x = 27
Hence the original dimension is 27cm by 10cm
