1. A package of sliced cheese costs 2.97 dollars, Their are 11 slices in each pack.
Question: how much would a package with 18 slices cost at the same price per slice? Explain or Show ur reasoning
Answer:
4.86 pack of 18
Step-by-step explanation:
If we consider adding a price to each slice from the 11 slice package. The price to each slice would be .27 cents. Now if we add 7 slices, each .27 cents each. The total price for the 18 package of sliced cheese would be 4.86
10x÷8=18
plz helppppppppppppppppppppppppppppppppppp
Hey there!
10x ÷ 8 = 18
MULTIPLY 8 to BOTH SIDES
10x ÷ 8 * 8 = 18 * 8
SIMPLIFY IT
NEW EQUATION: 10x = 144
DIVIDE 10 to BOTH SIDES
10x/10 = 144/10
CANCEL out: 10/10 because it gives you 1
KEEP: 144/10 because it helps simplify for the x-value
x = 144/10
x = 144 ÷ 2/10 ÷ 2
x = 72/5
Therefore, your answer is: x = 72/5
Good luck on your assignment and enjoy your day!

An object is thrown upwards with a speed of 20 m/s. After t seconds, its height can be solved using the formula h = 20t - 4.9t2 where h is the height and t is the time. After how many seconds is the object 19.6 meters high?
Step-by-step explanation:
h= 20t - 4.9t^2
when h=19.6m
19.6=20t - 4.9t^2
4.9t^2 -20t+19.6=0
solving quadratically
t= 1.64 seconds or t= 2.45 seconds
What is the equation in slope-intercept form of a line with
slope -5/4 and y-intercept 2?
For any linear function f(x) = mx + b, when does kf(x) = f(kx)?
Only when b = 0 or k = 1.
If f(x) = mx + b, then
f (kx) = m (kx) + b = mkx + b
while
k f(x) = k (mx + b) = kmx + kb
The two expression are identical only if
kb = b ===> kb - b = 0 ===> b (k - 1) = 0 ===> b = 0 or k = 1

find the intersection of the two lines by solving the system of equations please help I will give brainliest
Answer:
(-3, -5)
Step-by-step explanation:
We can add the two equations together so the x's cancel out:
x + y = -8
-x + y = -2
2y = -10
y = -5
We can substitute y in to get x:
x - 5 = -8
x = -3
This means the intersection is (-3, -5).
The new dolphin tank at the city aquarium is in the shape of a rectangular prism. It is long by wide by deep. To make the tank livable for the dolphins, the aquarium workers treat the water using bags of salt. The amount of water a bag of salt can treat is known in cubic feet.
(a) Find the volume of water in the tank in cubic feet.
(b) To make the tank livable for the dolphins, a bag of salt must be added for each 19.4ft$ of water. The aquarium doesn't have any salt on hand and the salt can only be purchased in whole bags. How many bags of salt must be purchased to treat the water?
(c) If each bag of salt costs $4.85, how much must the aquarium pay for salt to treat all the water in the new dolphin tank?
answer quickly
The volume of water in the tank is 35,100 cubic feet.
What is the volume of the rectangular prism?Volume = length × width × height
We have the following parameters based on the information provided;
Length = 20 meters
Width = 13 meters
Height = 5 meters
Substitute the values into the formula to get
Volume = 20 × 13 × 5
Volume = 1300 cubic meters
Convert the cubic yard into cubic feet
1 cubic yard = 27 cubic foot
⇒ 1300 yards = x
⇒ x = 27 × 1300
⇒ x = 35,100 cubic feet
Therefore, the amount of water a bag of salt can treat is 35,100 cubic feet

Write the equation of the line that has a slope of 4/5 and a y-intercept of -8.
The equation of any staright line can be written as y = mx + c , where m is its slope and c is its y - intercept . hence, equation of line with slope = 4/5 and y - intercept = -8 is,
→ y = 4/5x - 8
→ m - c = 4/5 + 8 = 12/5

A package of 6 pairs of insulated gloves costs $38.94. What is the unit price of the pairs of gloves? The unit price is $ per pair of gloves.
Answer:
6.49
Step-by-step explanation:
6 pairs of insulated gloves cost $38.94
That means 6 x (price of one glove) = 38.94
Let's say the price of on glove = x
The equation is :
6x = 38.94
x = 38.94 ÷ 6 (divide all sides by 6)
x = 6 + (2.94 ÷ 6) (Splitting numbers to multiples of 6)
x = 6 + 0.4 + ( 0.54 ÷ 6) (Splitting numbers to multiples of 6)
x = 6 + 0.4 + 0.09 (Adding all sums)
x = 6.49
Each pair of gloves cost 6.49

9(x/3+1)>6.
A.x>-5
B.x>2
C.x>5/3
D.x>-1
Answer:
D.
Step-by-step explanation:
We are given
9(x/3 + 1) >= 6
Divide 9 on both sides
x/3 + 1 >= 2/3
Subtract 1 on both sides
x/3 >= -1/3
Multiply 3 on both sides
x >= -1
what is the value of -4.5 degrees
Answer:30
Step-by-step explanation:
Find the value of cos 45° + sin 30° Solution: Given, cos 45° + sin 30° cos 45° + sin
30° = 1/√2 + ½ = (√2+1)/2 Question 2: Evaluate: 2 sin 60° – 4 cos 45° Solution: Given, 2 sin 60° – 4 cos 45° Since, sin 60° = √3/2 and cos 45° = 1/√2
Therefore, ⇒ 2 (√3/2) – 4 (1/√2) ⇒ √3 – 2√2 Question 3: Find Cos 45 + Cos 90. Solution: Cos 45° = 1/√2 Cos 90° = 0 Therefore, Cos 45° + cos 90° = 1/√2
