–27 ≥ t/5 Please help me as soon as possible
Answer:
t ≤ -135
Step-by-step explanation:
multiply each side by 5 which then cancels out the 5 in the fraction then turns -27 into -135. Since we multiplied negatives we flipped the sign.

The expression 27a^3 + 54a^2b + 36ab^2 + 8b^3 has a cube root of 3a + 2b
How to determine the cube root of the expression?From the question, the expression is given as
27a^3 + 54a^2b + 36ab^2 + 8b^3
The above expression is the cube of the sum of two numbers or expressions
Where the numbers are
27a^3 and 8b^3
The cube roots of 27a^3 and 8b^3 are represented as
∛27a^3 and ∛8b^3
Evaluate the cube roots
3a and 2b
Express as sum
3a + 2b
Hence, the cube root of the expression is 3a + 2b

Which of the following is a reflection of ( 2,4 ) across the x-axis?
a -2, 4
b 2, -4
c 4, 2
d -2, -4
Answer:
(2,-4)
Step-by-step explanation:
(2,4) is located in Quadrent I (+,+), if you reflect over the x-axis, it would be in Quadrent IV (+,-).

Katrina bought a new sofa. She was able to pay $100 at the
time she received the sofa. She will pay $22 each month on
the balance. The original cost of the sofa was $298. The
equation 100 + 22 = 298 represents this situation.
Use the equation to determine how many months will it take
Katrina to pay off the sofa.
================================================
Work Shown:
100 + 22x = 298
22x = 298-100 ........ subtracting 100 from both sides
22x = 198
x = 198/22 .............. dividing both sides by 22
x = 9
It will take 9 months for her to pay off the sofa.
She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.

B = 43
Step-by-step explanation:
1. Distribute.
5b + 15 = 4b - 28 + 2b
2. Combine like terms.
5b + 15 = 6b - 28
3. Get B on one side.
5b + 15 = 6b - 28
-5b + 28 = -5b + 28

Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{DF}{DE}[/tex] = [tex]\frac{y}{7}[/tex] ( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )

Taylor Swift wants to find the distance, AB, across a river. She starts at point B and walks along the edge of the river 94 ft and marks point C. Then she walks 76 ft further and marks point D. She turns 90° and walks until her final location and marks point E. Point E, point A, and point C are collinear.
Answer:
A) Ms. Swift can conclude that hey are similar, because line E,C,A is collinear, and they both are right triangles.
B) 158.3ft
Step-by-step explanation:
A) Having a collinear line makes the triangles similar, and because of their collinear line they are both right triangles.
B) The question tells you DE is 103 ft. You take 76ft and Square it giving you 5776ft You then take 103 and square it giving you 10609ft adding them together gives you 16385ft you take the square root of it and it gives you the hypotenuse of triangle CDE. To get the hypotenuse of triangle ABC you take The expression (AB/DE)=(BC/CD)=(AC/EC) step one (AB/DE)=(94ft/76ft)=AC/DE) step two (103ft/127ft)=(94ft/76ft)=(AC/DE) third step (103ft/127ft)=(94ft/76ft)=(128ft/158.3)

Decrease £13.20 by 15%
With an explanation (working out) plzzzz
Answer:
£11.22
Step-by-step explanation:
100% = £13.20
50% = £6.60
10% = £1.32
5% = £0.66
so you would add 10% and 5% together which gives you 15% and 15% is £1.98
and then you could to £13.20 - £1.98 which equals to £11.22
