Answer: T=7
Step-by-step explanation:
0t−15−7.5t=6−0.5t
2 Simplify 10t-15-7.5t10t−15−7.5t to 2.5t-152.5t−15.
2.5t-15=6-0.5t2.5t−15=6−0.5t
3 Add 1515 to both sides.
2.5t=6-0.5t+152.5t=6−0.5t+15
4 Simplify 6-0.5t+156−0.5t+15 to -0.5t+21−0.5t+21.
2.5t=-0.5t+212.5t=−0.5t+21
5 Add 0.5t0.5t to both sides.
2.5t+0.5t=212.5t+0.5t=21
6 Simplify 2.5t+0.5t2.5t+0.5t to 3t3t.
3t=213t=21
7 Divide both sides by 33.
t=\frac{21}{3}t=

Several paint mixtures are made by mixing blue paint and white paint. Paint Colors Blue Paint White Paint Mixture A 5 cups 12 cups Mixture B 6 cups 6 cups Mixture C 4 cups 12 cups Mixture D 5 cups 6 cups Which mixture has the highest ratio of blue paint to white paint?
Answer: Mixture C. 1:3
Step-by-step explanation:
given data:
paint mixtures
mixture blue white
A 12 5
B 6 6
C 12 4
D 6 5
Solution:
= [tex]\frac{4}{12}[/tex]
= [tex]\frac{1}{3}[/tex]
= 1:3
from the given data, mixture C has the highest number or ratio of blue paint to white paint which is 1:3 this means for every bucket of white paint there are 3 other buckets of blue.
Answer:
Mixture B

The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf hold? Write an equation to help solve this problem.
Answer:
328 books
An equation to solve the problem:
7x = 2296
Step-by-step explanation:
The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf hold? Write an equation to help solve this problem.
They said each shelf can hold the same number of books
And we have 7 shelves
Total number of books = 2296
Hence:
The number of books each shelf can hold = 2296 books/7 Shelves
= 328 books
Hence, each shelf can hold 328 books
An equation to solve this problem =
Number of books can be represented by x
Hence:
7x = 2296

Given: \overline{BD} \cong \overline{BE}, BD ≅ BE , \overline{DE} DE bisects \overline{AB} AB and \overline{DE} DE bisects \overline{BC}. BC . Prove: \overline{AB} \cong \overline{BC} AB ≅ BC .
Given:
[tex]\overline{BD} \cong \overline{BE}[/tex]
DE bisects [tex]\overline{AB}[/tex].
DE bisects [tex]\overline{BC}[/tex].
To prove:
[tex]\overline{AB} \cong \overline{BC}[/tex]
Proof:
DE bisects [tex]\overline{AB}[/tex]
Then, [tex]AD=BD[/tex]. ...(i)
DE bisects [tex]\overline{BC}[/tex].
Then, [tex]BE=CE[/tex]. ...(ii)
We have,
[tex]\overline{BD} \cong \overline{BE}[/tex] ...(iii)
Using (i), (ii) and (iii), we get
[tex]\overline{AD} \cong \overline{CE}[/tex] ...(iv)
Adding (iii) and (iv), we get
[tex]\overline{BD}+\overline{AD} \cong \overline{BE}+\overline{CE}[/tex]
[tex]\overline{AB} \cong \overline{BC}[/tex]
Hence proved.

Find the real numbers x and y that make the equation true. (2 points)
-3 + yi = x + 6i
Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6
what do i put in the blank ?
Answer:
Slope: 3
Y-intercept: -1
Linear equation: y=3x-1
frankie can build a speaker box in 120 minutes trash can build a speaker box 40 minutes faster if they work together how many minutes does it take them to build the speaker box
9514 1404 393
Answer:
48 minutes
Step-by-step explanation:
Each minute, F can build 1/120 of a speaker box, and T can build 1/80 of a speaker box. Working together, in 1 minute, they can complete ...
1/120 + 1/80 . . . . . speaker boxes
= 2/240 +3/240 = 5/240 = 1/48 . . . . speaker boxes
Then there will be 1 complete speaker box after 48 minutes.
PLEASE HELP ME!! An eagle eats 6 pounds of food every 8 days.How long does it take the eagle to eat 90 pounds of food
Answer:
15 days

Angela transfers 15% of each paycheck she received into her savings account. If she transferred $54 into her savings account last week, how much did she earn on that paycheck? Show your work using a model, proportion or equation
Answer:
$360
Step-by-step explanation:
Let the amount that she earned on the paycheck be represented by x
Hence,
15% of x = $54
Therefore:
15/100 × x = $54
15x/100 = $54
Cross Multiply
15x = $54 × 100
15x = $5400
x = $5400/15
x = $360
Therefore, the amount that she earned on that paycheck = $360

What is the equation, in standard form, of a parabola that models the values in the table?
y=4x^2+5x-6y=4x2+5x−6
:
Given points are :
x = -2 0 4
y=f(x) = 0 -6 78
We have to model the parabola with the help of these points
Solution:
We consider a standard equation of parabola y= ax^2+bx+cy=ax2+bx+c
now, we put the points in the equation we get,
at (-2,0) is 4a-2b+c=0
at (0,-6) is c=-6
at (4,78) is 78= 16a+4b+c
now, solving these equation we get, a= 4 , b= 5 , c= -6
so the equation formed with these points is y=4x^2+5x-6y=4x2+5x−6
we can see this in the graph attached.

If you are buying at item at a store for a price of $61, and there is a 6.7% tax added on top, what would be the total amount due at the register, to the nearest cent?
Answer:
The total amount due at the register will be: $65.09
Step-by-step explanation:
The cost of an item = $61
tax on item = 6.7%
The tax amount = 6.7% × 61
= 0.067 × 61
= $ 4.09
The total cost = cost of an item + tax amount
= $61 + $4.09
= $65.09
Therefore, the total amount due at the register will be: $65.09

Consider the polynomial function:
p(x) = 3x3 + 10x2 + ax - 6
where a is an unknown real number.
If
(x + 3)
is a factor of this polynomial what is the value of a? Show all the steps below.
Step-by-step explanation:
By Factor Theorem, p(-3) = 0.
Therefore 3(-3)³ + 10(-3)² + (-3)a - 6 = 0 and a = 1.
