t = ⁵⁄₂ or 2.5Explanation:
3t + 7 = 2 + 5t
Simplify both sides of the equation3t + 7 = 5t + 2
Subtract 5t from both sides3t + 7 − 5t = 5t + 2 − 5t
−2t + 7 = 2
Subtract 7 from both sides−2t + 7 − 7 = 2 − 7
−2t = −5
Divide both sides by -2
−2t / -2 = −5 / -2
Simplifyt = ⁵⁄₂
Turn the fraction into a decimalt = 2.5
t = ⁵⁄₂ or 2.5
Find (-21)+(-13)+20.
Answer:
14
Step-by-step explanation:
-21+-13+20=14
This is true because when subtracting negatives by negatives you pretty much add them and then when you add a positive to a negative you are technically removing the negative by the amount you are adding.
In short its kind of like using inverse operation in a way.

Write a polynomial in standard form with the zeros –4, 0, 1, and 4.
Answer:
uhhm
Step-by-step explanation:
....
The required polynomial in standard form with zeros –4, 0, 1, and 4 is x⁴- x³ - 16x²+16x
Polynomial functions are functions that have a leading variable of 3 and above.
Given the zeros of a polynomial as -4, 0, 1, and 4, their corresponding factors will be:
(x+4)), x-0, x-1 and x - 4
To get the polynomial function required, we will take the product of the factors as shown:
= x(x-1)(x+4)(x-4)
= (x²-x)(x²-4²) (Note that (x+4)(x-4) is from different of two square)
f(x)= x⁴-16x²-x³+16x
Rearranging
f(x) = x⁴- x³ - 16x²+16x
Hence the function x⁴- x³ - 16x²+16x gives the required polynomial in standard form.

the area of a room is 55.929 square meters if its width is 5.43 meters, what is its length
Answer:
10.3m
Step-by-step explanation:
area of a rectangle is width times length, so you have to rearrange the equation
55.929 ÷ 5.43 = 10.3
Answer:
10.3 meters
Step-by-step explanation:
Area = length x width
55.929 = ? x 5.43
Divide 5.43 from 55.929
55.929/5.43 = 10.3 meters
Check = 10.3 x 5.43 = 55.929
A fair 10 sided dice numbered 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 is rolled once. What is the PERCENTAGE probability that it lands on a number that is prime? *
Answer:
40% probability that it lands on a number that is prime.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
10 sided dice
So 10 total outcomes.
Prime numbers:
Of those, 2, 3, 5 and 7 are prime, so 4 of the outcomes.
4*100/10 = 40%
40% probability that it lands on a number that is prime.

Neda sells televisions. She earns a fixed amount for each television and an additional $15 if
the buyer gets an extended warranty. If Neda sells 19 televisions with extended warranties, she
earns $1,615. How much is the fixed amount Neda earns for each television?
Answer:
$70.
Step-by-step explanation:
Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:
(19 x 15) + X = 1615
285 + X = 1615
X = 1330
1330/19 = 70
Thus, the fixed amount Neda receives for each television is $70.
Answer: $70
Step-by-step explanation:
Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:
(19 x 15) + X = 1615
285 + X = 1615
After this step, you can see that the x is already isolated and no number next to it. This is a good thing because you only need to subtract 285 on both sides.
x = 1330
Then...
1330/19 = 70.
Thus, the fixed amount Neda receives for each television is $70.

a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new elevation of the submarine
Answer:
[tex]New = -92\frac{1}{8}[/tex]
Step-by-step explanation:
Given:
[tex]x = -75\frac{3}{4}[/tex] --- Position
[tex]\triangle x = -16\frac{3}{8}[/tex] --- Change
Required
Find the new position
The new position is calculated as:
[tex]New = x + \triangle x[/tex]
[tex]New = -75\frac{3}{4} - 16\frac{3}{8}[/tex]
[tex]New = -75.75 - 16.375[/tex]
[tex]New = -92.125[/tex]
[tex]New = -92\frac{125}{1000}[/tex]
[tex]New = -92\frac{1}{8}[/tex]
What is the area of the shaded region?
Answer:
approx 54.94
Step-by-step explanation:
area of square is 16^2=256
area of circle is pi(8^2)= approx 201.06
256-201.06=54.94
Answer:
[tex] 55.04 \: {cm}^{2} [/tex]
Step-by-step explanation:
Side length of square = 16 cm
Diameter of circle = Side of square = 16 cm
Radius of circle = 16/2 = 8 cm.
Area of the shaded region =
Area of square - Area of circle
[tex] = {16}^{2} - \pi\times {8}^{2} \\ \\ = 256 - 3.14 \times 64 \\ \\ = 256 - 200.96 \\ \\ = 55.04 \: {cm}^{2} [/tex]
Write the ratio for sin x, cos x and tan x
Answer:
Sin X = 15/17
Cos X = 8/17
Tan X = 15/8
Step-by-step explanation:
Recall, SOHCAHTOA.
Thus:
Sin X = opp/hyp
opp = 15
hyp = 17
✅Sin X = 15/17
Cos X = adj/hyp
Adj = 8
Hyp = 17
✅Cos X = 8/17
Tan X = opp/adj
Opp = 15
Adj = 8
✅Tan X = 15/8

A bottle holds 2 pints. A carton holds 3 cups. What is the total the two containers hold in fluid ounces?
A. 6 fluid ounces
B. 32 fluid ounces
C. 56 fluid ounces
D. 66 fluid ounces
Answer:
C
Step-by-step explanation:
One Pint is 16 fluid ounces, and since their are 2 that would be 32 fluid ounces. Then 1 cup is 8 fluid ounces, and since their are 3 that would be 24 fluid ounces. When added thogether the result would be 56 fluid ounces.
The total that the two containers hold in fluid ounces is 56 fluid ounces.
What are Measurements?Measurement is the method of comparing the properties of a quantity or object using a standard quantity.
Measurement is essential to determine the quantity of any object
Given that,
Capacity of a bottle = 2 pints
Capacity of a carton = 3 cups
We have to convert both of this in to fluid ounces.
1 pint = 16 fluid ounces
Capacity of a bottle = 2 pints = 2 × 16 fluid ounces = 32 fluid ounces
1 cup = 8 fluid ounces
Capacity of a carton = 3 cups = 3 × 8 fluid ounces = 24 fluid ounces
Total capacity of two containers = 32 fluid ounces + 24 fluid ounces
= 56 fluid ounces
Hence the capacity of both containers is 56 fluid ounces.

Slope = -3.5
Step-by-step explanation:
Find the slope using any two given pair of values. Let's use (6, -21) and (12, -42).
Slope = ∆y/∆x
Slope = (-42 -(-21)) / (12 - 6)
Slope = -21/6
Slope = -3.5
