A pan balance has 3 cubes on one pan and 11 cubes on the other pan. Lucy thinks she should add 7, 8, 9, or 10 cubes to make the pans balance. How can you use the equation 3 + c = 11 to find the number of cubes Lucy should add?
Answer:
8
Step-by-step explanation:
11-3=c
c=8
The number of cubes Lucy should add is 8.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, a pan balance has 3 cubes on one pan and 11 cubes on the other pan.
The equation to represent the situation is 3+c=11
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Now, c=11-3
c=8
Therefore, the number of cubes Lucy should add is 8.

Answer:
Gina spent more money, she spent 2 more cents than Amy.
Step-by-step explanation:
Gina: 1.38x2=$2.76 1.38/2=69 cents
2.76+69= $3.45
Amy: 0.98x3=$2.94 0.98/2=49 cents

figure pqsr and figure p's'q'r are shown in the coordinate grid below
which statement describes how figure pqsr was transformed to form the image p'q'r's?
A. a translation across the x-axis
B.a reflection across the x-axis
C.a translation across the y-axis
D. a reflection across the y -axis
Answer:
D
Step-by-step explanation:
A translation would be shifting the figure in any direction, but the figure would retain it's shape and pqrs would all be at their same corners. A reflection means the figure will essentially be "flipped" across an axis, and in this case it would be the y-axis as you can imagine "folding" over the y-axis and having the figures line up.

5 The smallest angle of a triangle, in degrees, is p.
The second angle is 4 times the smallest angle.
The third angle is 5 times the smallest angle.
a Write an equation for the angles in the triangle in terms of p.
b Find the size of the largest angle in the triangle.
b in paticular
Answer: b = 90
Step-by-step explanation:
Full triangle is 180
5 + 4 = 9 + 1 (the smallest angle)
180 ÷ 10 = 18
First and smallest angle is 18
p= 18
Second angle is 72
18 × 4 = 72
Thrid angle is 90
18 × 5 = 90
b = 90
18 + 72 = 90 + 90 = 180

What is the distance between (2, -2) and (-8, -2)?
Given:
(2, -2)(-8, -2)To find: The distance between the two points.
Answer:
Formula to find the distance:
[tex]\sf Distance\ =\ \sqrt{\Bigg(x_2\ -\ x_1\Bigg)^2\ +\ \Bigg(y_2\ -\ y_1\Bigg)^2}[/tex]
From the given data, we have:
x₁ = 2x₂ = -2y₁ = -8y₂ = -2Using them in the formula,
[tex]\sf Distance\ =\ \sqrt{\Bigg(-8\ -\ 2\Bigg)^2\ +\ \Bigg(-2\ -\ (-2)\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{\Bigg(-10\Bigg)^2\ +\ \Bigg(-2\ +\ 2\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{100}\ =\ \bf 10\ units.[/tex]
Therefore, the distance between (2, -2) and (-8, -2) is 10 units.
Hope it helps. :)
The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird in feet per second?
Answer:
[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]
Step-by-step explanation:
Given
[tex]Altitude\ Change = -4\frac{1}{4} \ ft[/tex]
[tex]Time = 2\frac{1}{2}\ s[/tex]
Required
Determine the average change
This is calculated as follows:
[tex]Average\ Change = \frac{Altitude\ Change}{Time}[/tex]
This gives:
[tex]Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}[/tex]
[tex]Average\ Change = -4\frac{1}{4}/2\frac{1}{2}[/tex]
Convert to improper fractions
[tex]Average\ Change = -\frac{17}{4}/\frac{5}{2}[/tex]
Convert to multiplication
[tex]Average\ Change = -\frac{17}{4}*\frac{2}{5}[/tex]
[tex]Average\ Change = -\frac{17}{2}*\frac{1}{5}[/tex]
[tex]Average\ Change = -\frac{17}{10}[/tex]
[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]
A computer store buys a computer system at a cost of 463.20$. The selling price was first at $772, but then the store advertised 40% a markdown on the system.Find the current sale price.
The current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
What is the selling price?The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.
Given:
The cost price = $463.20,
The initial selling price = $772,
We know that Markdown= Selling price × markdown rate
Markdown = 772 × 40%
Markdown = 772 × 0.4
Markdown = $308.8
So new selling price = The initial selling price - markdown price
Current selling price = 772 - 308.8
Current selling price = $463.2
Therefore, the current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
