Answer:
12 coins
Step-by-step explanation:
Points scored by collecting 7 coins = 581
Number of coins required to collect 996 points
Let Number of coins = c
7 coins = 581 points
c coins = 996 points
Cross multiply :
581 * c = 996 * 7
581c = 6972
Divide both sides by 581
581c / 581 = 6972 / 581
c = 12
Hence, number of coins required to collect 996 points is 12
Solution:
The graph shows how the volume, V, of the cube changes as the length of the sides, S, changes.
On analysing the graph ,
This table shows how the volume, V, of the cube changes as the length of the sides, S, changes.
Option C is the correct option for the table that matches the graph.
Answer:
y = 2x + 7
Step-by-step explanation:
y = mx + b The point (-2,3) gives us an x value and a y value that we can use. We are also give the slope (m). All we need to do is figure out the b (y-intercept) value.
y = mx + b
3 = 2(-2) + b
3 = -4 + b Add for to both sides
7 = b We know have every thing that we need to write the equation. We have the slope (m) which is 2 and the b (y-intercept) that we just figured out is 7
y = 2x + 7
Variables: DescriptionIn mathematics, a variable is a symbol used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.
Properties: a property is any characteristic that applies to a given set.
Expression: DescriptionIn mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression. Since taking the square root is the same as raising to the power, is also an algebraic expression.
Equation: In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. The most basic and common algebraic equations in math consist of one or more variables.

To find this you can always use a calculator, if your teacher allows you to. Just remember to punch in the negative signs correctly and don't mistake them for subtraction signs. Also if you don't know what product means, that means the answer of a multiplication problem so for example 9 is the product of 3x3 or 5 is the product of 5x1. The answer to your question is 104. Maybe next time you can solve it on your own! :)
