Which property is represented 7(t+u)= 7t + 7u
Answer:
distributive property
Step-by-step explanation:
The distributive property is
a(b + c) = ab + ac
where each term in the parenthesis is multiplied by the value outside.
Then
7(t + u) = 7t + 7u
Solve.
5.25t + 5 = 16.5t + 14
The solution is t =
i realy need helpppppp
Answer:
-0.8 is the correct answer for this question
Step-by-step explanation:
mark me as brainliest
Answer:
t=-0.8
Step-by-step explanation:
You want to get the 't' by itself, so you will subtract 5 from both sides
5.25t=16.5t+9
Now, you want to subtract 16.5t from both sides
-11.25t=9
now you divide -11.25 from both sides.
t=-0.8
Stacey has earned $9 interest over the past 20 months with an initial investment of $150. What is the simple interest rate she is earning? Express your answer to the nearest tenth of a percent. (It wants me to use the formula I=Prt which I don't remember)
Answer:
3.6%
Step-by-step explanation:
We are solving the above question, using the simple interest Formula:
I = PRT
Where
I = Interest = $9
P = Principal = $150
R = Interest rate = ??
T = Time in years = 20 months
We convert this to years
12 months = 1 year
20 months = x
x = 20/12
x = 1.67 years
Hence, making R the subject of the formula
R = I/PT
R = 9/150 × 1.67
R = 9/250.5
R = 0.0359281437
Converting to percentage
R = 0.0359281437 × 100
R = 3.59281437%
R = 3.6 %
The simple interest rate she is earning is 3.6%
Matthew plays soccer for h hours per day for five days in a row. Over the weekend, he played in a soccer tournament for a total of 6.5 hours. Which expression represents the number of hours Matthew played soccer in a full week? 5 + h + 6.5 5h + 6.5 StartFraction h over 5 EndFraction + 6.5 11.5hMariah purchases three hair barrettes by using a gift card, which starts with a balance of $35.79. Which expression models her purchase? 3 b minus 35.79 35.79 + 3 b 35.79 b minus 3 35.79 minus 3 b
Answer:
Part(A): The expression which represents the number of hours Matthew played soccer in a full week is [tex]5h + 6.5[/tex]
Part(B): the expression models her purchase is [tex]35.79-3b[/tex].
Step-by-step explanation:
Consider the provided information.
Part(A):
Matthew plays soccer for h hours per day for five days and he played a soccer tournament for a total of 6.5 hours.
So the required expression is: [tex]5h + 6.5[/tex]
Where 5h represents time spent in 5 days and 6.5 is the hours of the soccer tournament.
Part(B):
Mariah purchases three hair barrettes by using a gift card.
Let the cost of each barrette is b.
So the cost of 3 barrettes is: [tex]3b[/tex]
She uses a gift card with a balance of $35.79. Therefore subtract [tex]3b[/tex] from $35.79.
Her purchase can be expressed as:
[tex]35.79-3b[/tex]
Hence, the required expression is [tex]35.79-3b[/tex].
Answer:
5h + 6.5

What is the value for x=
Answer:
x = 2[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Since the 2 legs are congruent, both 6 then the triangle is isosceles.
The line from the vertex to the base is a perpendicular bisector, dividing the base into 2 parts of 4 units.
Using Pythagoras' identity in one of the right triangles.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 4² = 6²
x² + 16 = 36 ( subtract 16 from both sides )
x² = 20 ( take the square root of both sides )
x = [tex]\sqrt{20}[/tex] = [tex]\sqrt{4(5)}[/tex] = 2[tex]\sqrt{5}[/tex]

What are the answers to these two things? 3x -2 + 4 = x - 6 and x + 8 = 5x + 6 Im gonna need step by step also, thanks!
Answer:
For 3x-2+4=x-6
[tex]3x - 2 + 4 = x - 6 \\ 3x - x = - 6 - 4 + 2 \\ 2x = - 8 \\ x = \frac{ - 8}{2} \\ x = - 4[/tex]
for x+8=5x+6
[tex]x + 8 = 5x + 6 \\ x - 5x = 6 - 8 \\ - 4x = - 2 \\ x = \frac{ - 2}{ - 4} \\ x = \frac{1}{2} [/tex]
Please answer correctly !!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:
x = 8
Step-by-step explanation:
well using the theorem we have
[tex]\frac{6}{9}=\frac{x}{12}\\\\\frac{2}{3}=\frac{x}{12}\\\\12[\frac{2}{3}]=12[\frac{x}{12}]\\\\4\cdot 2=x\\\\x=8[/tex]

Subtract-3c2 + 12cd – 4d2 from 4c2 + 3cd + 2d?.
Your answer should be a polynomial in standard form.
Answer:
Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]
Step-by-step explanation:
We need to Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex]
(Note: Considering 2d^2 instead of 2d as thinking it typo error)
Subtracting from means we have to subtract [tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)[/tex]
Subtracting:
[tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)\\=4c^2 + 3cd + 2d^2 +3c^2 - 12cd + 4d^2[/tex]
Combining like terms (Like terms are those that have same variables like 4c^2 and 3c^2 are like terms, 3cd and -12cd are like terms, 2d^2 and 4d^2 are like terms)
[tex]=4c^2+3c^2 + 3cd-12cd + 2d^2+4d^2 \\=7c^2-9cd+6d^2[/tex]
So, Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]
What do you know about the solution(s) to the system of linear equations?
The solution is (-2,0).
There are infinitely many solutions.
There is no solution
The solution is (4, -1).
Answer:
No solutions.
General Formulas and Concepts:
Algebra I
Solving systems of equations by graphingStep-by-step explanation:
Where the 2 lines intersect is the solution set to the systems of equations.
If the lines are the same, they will have infinite solutions (will always intersect).
If the lines are parallel, they will have no solutions (will never intersect).
According to the graph, we see that the lines are parallel. Therefore, the systems has no solutions.

If y varies inversely as x. Using the coordinates (5, 3) and (x, 2.5), find the missing value x.
Answer:
(6, 2.5 )
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k substitute the coordinate point (5, 3 ) into the equation, that is
3 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )
15 = k
y = [tex]\frac{15}{x}[/tex] ← equation of variation
Using (x, 2.5 ) with y = 2.5 , then
2.5 = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )
2.5x = 15 ( divide both sides by 2.5 )
x = 6
Thus point is (6, 2.5 )

what is two and a half added to four and a half?
Answer:
7
Step-by-step explanation:
Yesterday, the movie theater brought in $1,440 in ticket
sales and $295.25 in food sales. Today, ticket sales were
three-fourths as much as yesterday, and food sales were
down by $33.50. Nina wrote the expression
(1440) + 295.25 + (-33.50)
to find today's total sales. Is she correct? Explain.
Answer:
No. Nina forgot to adjust ticket sales.
Step-by-step explanation:
3/4(1440) + (295.25-33.50)
=1341.75
She didn't add the 1/4 less sales from the next day, Therefore she is wrong.
