Step-by-step explanation:
what is THE partial product ? there is a mistake in your problem description.
it must read "what are valid partial products".
1262×3 has the following partial products :
1000×3 = 3000
200×3 = 600
60 × 3 = 180
2×3 = 6
-----------
3786
so, D seems to be the best answer, because both numbers are partial products here.
A, B and C have each only one correct.
On a family outing, Tyler bought 5 cups of hot cocoa and 4 pretzels for
$18.40. Some of his family members would like a second serving, so he
went back to the same food stand and bought another 2 cups of hot cocoa
and 4 pretzels for $11.20.
Here is a system of equations that represent the quantities and constraints
in this situation.
5c + 4p = 18.40
2c + 4p - 11.20
If we add the second equation to the first equation, we have a new equation: 7c + 8p = 29.60
Explain why the same (c, p) pair that is a solution to this new equation.

Answer:
the properties of equality tell you so
Step-by-step explanation:
A couple of properties of equality come into play here:
the addition property of equalitythe substitution property of equalityEach of the properties of equality tells you an operation you can perform on an equation without changing the values of the variables that satisfy that equation.
If we start with the equation ...
5c + 4p = 18.40
and we add 11.20 to both sides, we have not changed the values of the variables that satisfy this equation. This is the addition property of equality.
(5c +4p) +11.20 = (18.40) +11.20
The substitution property of equality says I can substitute anything for its equal. The second given equation tells me that 2c +4p = 11.20. This means I can use 2c+4p wherever 11.20 might be found without changing any variable values. In the equation we got from addition, we can now make this substitution, and we have ...
(5c +4p) +(2c +4p) = (18.40) +(11.20)
7c +8p = 29.60 . . . . . . . collect terms
We obtained this equation using properties of equality that guarantee solutions to these equations are not altered by the process.
_____
*Additional comment
Technically, by doing the "collect terms" step, we have made the assumption that the values of c and p that satisfy the first equation are the same as the values of c and p that satisfy the second equation. This is usually the case we're interested in.

answer is -3
Step-by-step explanation:
4=x1 and 2=y1
3=x2 and 5=y2
y2-y1/x2-x1
5-2/3-4
3/-1 or -3
since we are finding the slope,we have to minus the y2 from the y1 over the x2-x1 and we minus then simplify.

still dont get it...
Answer:
You can tell they are scaled copies because they retain the same shape as each other, even though they are different sizes. Another way you can tell is to find the measure of all the sides for both shapes and see if the ratio from the original to image is the same for all sides (indicating that all sides were scaled by the same amount)

What is the completely factored form of f(x)=x3−8x2+5x+14, given that x = 7 is a root?
Group of answer choices
f(x) = (x + 7)(x - 1)(x + 8)
f(x) = (x + 2)(x - 1)(x + 7)
f(x) = (x + 14)(x - 8)(x + 5)
f(x) = (x - 2)(x - 7)(x + 1)
f(×)=(×+7)(×-1)(×+8)
Answer:
answer is 4
Step-by-step explanation:
we want to get 14
so 14 = -2*-7*1 so when simplifying last equation will get the constan number 14
Find the distance between R (3, 4) and T (7, 2).
Answer:
[tex]\sqrt{20}[/tex] or 4.47
Step-by-step explanation:
To find the distance between two points on a plane, you can use the distance formula: [tex]d=\sqrt{(y^{2}-y^{1})^2 + (x^{2}-x^{1})^2 }[/tex]
Plug your values in to get the distance between the two points.
[tex]d=\sqrt{(y^{2}-y^{1})^2 + (x^{2}-x^{1})^2 }[/tex]
[tex]d=\sqrt{(2-4)^2 + (7-3)^2 }[/tex]
[tex]d=\sqrt{(-2)^2 + (4)^2 }[/tex]

arrange 64 72 27 83 in ascending order
Answer: 27,64,72,83
Step-by-step explanation: By ascending order it is basically asking you to sort the numbers from least to greatest. So the order would be 27,64,72,and 83.
Answer:
27, 64, 72, 83
Step-by-step explanation:
27
is the least
64
is bigger than 27 yet less than 72 and 83
72
bigger than both 27 and 64 yet is less than 83
83
is last because it is the biggest one of them all

Step-by-step explanation:
Andrea is buying some new shirts and sweaters. She is Able to buy three shirts and two sweaters for $113 or she is able to buy T-shirts and four sweaters for 166 how many dollars does a shirt cost how many dollars does a sweater cost
Answer:
y = 28.75
x = 26.5
Step-by-step explanation:
I think the amount of the second T-shirts purchased should be 2
Let the cost of each shirt be $ x, and the cost of each sweater be $ y.
Since the cost of each shirt is $ x, the cost of 3 shirts will be $ 3x and the cost of 2 shorts will be $ 2x.
Likewise, cost of each shirt is $ x, so the cost of 2 shirts will be $ 2x and cost of 4 sweaters will be $ 4y.
Andrea was able to buy 3 shirts and 2 sweaters for $113. This means:
Cost of 3 shirts + Cost of 2 sweaters = 113
Equation 1: 3x + 2y = 113
She was able to buy p shirts and 4 sweaters for $166. This means:
2x + 4y = 166
Dividing both sides by 2, we get:
Equation 2: x + 2y = 84
Subtracting Equation 1 from Equation 2, we get:
x + 2y - (3x + 2y) = 166 - 113
x + 2y - 3x - 2y = 53
2x = 53
x = 26.5
Using the value of x, in Equation 2, we get:
26.5 + 2y = 84
2y = 57.5
y = 28.75
Since, x represents the cost of shirt, the cost of each shirt is $ 26.5.
y represents the cost of sweater, so the cost of each sweater is $ 28.75.

The length of a rectangle is 3 ft longer than its width.
If the perimeter of the rectangle is 46 ft, find its area.
Answer:
Area = 130 ft^2
Step-by-step explanation:
Area =length * width
Perimeter = 2(L + W)
L=3+x
W= x
Perimeter= 2(3+x+x) =2(3 +2x)=6+4x=46 so x=10
L=3 +10= 13
W= 10
Area = 13* 10 130

In 803,349 , how is the value of the 3 in the thousands pace related to the 3 I the hundreds place
9514 1404 393
Answer:
it has 10 times the value
Step-by-step explanation:
In a base-10 number system, each digit to the left has a value 10 times the one to its right.
3 in the thousands place has a value of 3000
3 in the hundreds place has a value of 300
The digits values are related by a factor of 3000/300 = 10. The digit in the thousands place has 10 times the value of the digit in the hundreds place.
