4(1)+2(3)=10
Nora would score 10 and for x free throws and y three point shots x + 3y.
What is linear Equation?When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.
One-variable linear equations and two-variable linear equations exist.
Given
points on free throws = 1
points on 4 free throws = 4x1 = 4
and points on 2 three point shot = 2x3 = 6
total points are 4 + 6 = 10
and if she made x free throws then points are = 1x
and for y three point shots = 3y
total points for x free and y three point shots
x + 3y
Hence the points are 10 and x + 3y.

a^2-36=5a
A. {4,-9}
B. {5+√61/2, 5-√61/2}
C. No solution
D. {9,-4}
Answer:
D
Step-by-step explanation:
Given
a² - 36 = 5a ( subtract 5a from both sides )
a² - 5a - 36 = 0
Consider the factors of the constant term (- 36) which sum to give the coefficient of the a- term (- 5)
The factors are - 9 and + 4 , since
- 9 × + 4 = - 36 and - 9 + 4 = - 5 , then
(a - 9)(a + 4) = 0 ← in factored form
Equate each factor to zero and solve for a
a - 9 = 0 ⇒ a = 9
a + 4 = 0 ⇒ a = - 4
solution is { - 9, 4 } → D

Would a prism with a volume of 36 be the same if built with centimeter cubes, inch cubes, or foot cubes?
Answer:
Yes
Step-by-step explanation:
It is given that a prism is built that have a volume of 36.
Now if the prism is rebuild with either centimeter cubes or the inch cubes or foot cubes will have the same volume of 36 as the volume here is constant. The centimeter cubes used to build the prism will be smaller in size and will require more of the cubes to build the cube for a volume of 36.
Similarly, if we take inch cubes or the foot cubes, to build a prism having a volume of 36, we need to take less number of the cubes accordingly.
There are seven nickels and seven dimes in your pocket. You randomly pick a coin out of your pocket and place it on a counter.
Answer:
3/13
Step-by-step explanation:
Here is the full question
There are seven nickels and seven dimes in your pocket. You randomly pick a coin out of your pocket and place it on a counter. Then you randomly pick another coin. Find the probability that both coins are nickels.
Because there is no replacement, after you pick the first coin, the number of coins in your pocket becomes 13 and the number of nickels in your pocket becomes 6
probability that both coins are nickels = probability that the first coin is a nickel x probability second coin is a nickel

The measures of the exterior angles of an octagon are x°, 2x°, 4xº, 5x°, 6x°, 8xº,
9x", and 10x°. Find the measure of the smallest exterior angle.
Answer:
8°
Step-by-step explanation:
The sum of the measures of the exterior angles of a any polygon = 360.
So, x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360
45x = 360
x = 8°
The measure of the smallest exterior angle would be equal to 8°
What is Octagon ?In geometry, a Octagon is a eight - sided polygon. For a [n] sided polygon -
Sum of interior angles = (n - 2) × 180°Each interior angle of a regular polygon = [(n − 2) × 180°/n]Sum of exterior angles = 360°According to the question, we have - A Octagon and the measures of the exterior angles of an octagon are x°, 2x°, 4x°, 5x°, 6x°, 8x°, 9x° and 10x°.
The sum of the exterior angles of the octagon will be 360°.
Therefore, we can write -
x + 2x + 4x + 5x + 6x + 8x + 9x + 10x = 360°
45x = 360°
x = 360/45
x = 8
The smallest exterior angle would be equal to [x]° = 8°
Therefore, the measure of the smallest exterior angle would be equal to 8°

Eva took a taxi from her house to the airport. The taxi company charged a pick-up fee of $3.20 plus $3 per mile. The total fare was $33.20, not including the tip
Answer: 10 miles
Step-by-step explanation:
You can set this up as an equation where x will represent the number of miles charged. So if we know how much the pick up fee is, how much it is per mile and the total charge we can set up the equation as follows:
3.20 + 3x = 33.20
If we solve for x we will find out how many miles she traveled. So to do so we need to get x on one side and the other numbers on the other side of the equal sign. So to begin we'll subtract 3.20 from both sides:
3x = 30.00
and then divide both sides by 3:
x = 10
So she traveled 10 miles.
The Taxi ride was 10 miles.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We can set an equation where x will represent the number of miles charged. So, the total charge we can set up the equation as follows:
3.20 + 3x = 33.20
If we solve for x we will find out the miles she traveled.
Then subtract 3.20 from both sides:
3x = 30.00
then divide both sides by 3;
x = 10
Therefore, she traveled 10 miles.

One of the legs of a right triangle measures 6 cm and its hypotenuse measures 10 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
let base = 6cm
perpendicular =x cm
hypotenuse =10cm
by using Pythagoras law
hypotenuse ²=perpendicular ²+base²
10²=x²+6²
100-36=x²
x=√64=8cm
the measure of the other leg is 8cm
The measure of the other leg of the right triangle is equal to 8 cm.
Let the other leg of the right triangle be the opposite side.Given the following data:
Adjacent = 6 cmHypotenuse = 10 cmTo find the measure of the other leg, we would apply Pythagorean's theorem:
Mathematically, Pythagorean's theorem is given by the formula;
[tex]Hypotenuse^2 = opposite^2 + adjacent^2[/tex]
Substituting the given parameters into the formula, we have;
[tex]10^2 = opposite^2+6^2\\\\100= opposite^2+36\\\\Opposite^2=100-36\\\\Opposite^2=64\\\\Opposite=\sqrt{64}[/tex]
Opposite = 8 cm
