The way I learned it was that if they dont have the same variables dont touch them, so what I did was multiply the like numbers (2 and 5). Why are they alike? Because they don't have a variable! I then just put the X sign there to show that there is no other way to multiply this. If it where addition, it would be 10+a so that would equal 10a.
Question 7 Mai wants to construct a regular hexagon inscribed in the
circle centered at C. Will these instructions work to finish the hexagon
from the construction given? Why? Step 1 Draw the circle centered at D
with radius CD. Step 2 Mark the intersection of the circle with the circle
centered at C, and label that point E. Step 3 Draw the circle centered at E
with radius DE. Step 4 Mark the intersection of the circle with the circle
centered at D, and label that point F. Step 5 Connect ABCDEF to make a
regular hexagon.

Mr. Wood wants to put a carpet in his brand new classroom. He is going to install a carpet that is 14 feet long and 9.5 feet wide. What is the total area of the new carpet?
Answer:
133 feet²
Step-by-step explanation:
To find the area of a shape you need to use the the formula "length(L) times(×) width(W)". In this problem it gives you both the length and width which means you just need to multiply the two numbers to get your answer. (You need to add feet because that's what is being used in the problem and ²(squared) because area is measured in square units.

Which relationship is an example of a proportional relationship?
helppp?
Answer: “samuel earns $20 for each lawn he mows”
Step-by-step explanation:
The statements that represent proportional relationship are statement [1], [2] and [4].
What is proportional relationship? What is equation modelling? What is a mathematical equation and expression?The proportional relationship between [y] and [x] is given by -y = mx + c
for [c] = 0
m = y/x
where [m] is the constant of proportionality.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are some statements depicting proportional relationship.
For the statement [1], we can write the equation as -
y = 0.08x + 59
For the statement [2], we can write the equation as -
y = 25x + 45
For the statement [1], we can write the equation as -
y = 20x
Therefore, the statements that represent proportional relationship are statement [1], [2] and [4].

Which choice is equivalent to the expression below?
2^7.19
Answer:
B
Step-by-step explanation:
Exponents Law:
[tex]a^{m}*a^{n} = a^{m+n}[/tex]
In exponent multiplication, if bases are same, add the powers(exponents).
Write 7.19 in expanded form: 7.19 = 7 + 0.1 + 0.09. Now apply the exponent rule.
[tex]2^{7.19}=2^{7+0.1+0.09}\\\\=2^{7}*2^{0.1}*2^{0.09}\\\\= 2^{7}*2^{\frac{1}{10}}*2^{\frac{9}{100}}[/tex]

Mia, Thomas, and Jasmine are competing in a barrel race. Thomas's time is 8 seconds more than Mia's time. Jasmine's time is į times the quantity of 21 seconds more than Mia's time. The sum of all three times is 71 seconds. what represents this situation and what is the value of m
Given that,
Thomas's time is 8 seconds more than Mia's time.
Jasmine's time is į times the quantity of 21 seconds more than Mia's time
The sum of all three times is 71 seconds.
To find,
The value of m.
Solution,
Let Mia's time is m.
Thomas's time = 8+m
Jasmine's time = 21 + 8+ m
ATQ,
m + 8 + m + 21 + 8 + m = 71
3m + 37 = 71
3 m = 71 - 37
m = 34/3
m = 11.34
So, the value of m or Mia's time is 11.34 seconds.
Answer:
m+1/3(m+21)+m+8=71, m=24

Gabby has 20 coins in her pocket that are quarters, dimes, and nickels. The total value of the coins is $2.70. The number of nickels that she has is equal to the number of quarters plus the number of dimes. Choose the system of equations that can be solved to find the number of quarters, 9, dimes, d, and nickels, n, that Gabby has.
Answer:
There's 9 nickels and no dimes
Step-by-step explanation:
the quarters equal $2.25
so there is at least 9 nickel's witch equals .45 cents add them and get $2.70 so
The system of equations to find the number of quarters, 9, dim, d, and nickels, n, that Gabby has are;
n = q + dn = 10q +d = 10Since, the total value of quarters, dim, and nicke is; $2.70.
Since the number of nickels that she has is equal to the number of quarters plus the number of dimes; we have;
n = q + dSince, Gabby has 20 coins in her pocket.
n + q + d = 20Therefore 2n = 20 from n = q + d
n = 10Read more on system of equations:
