Answer:
The answer is -21
Step-by-step explanation:
The elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
It is given that , diver is 1 foot deeper than 2/3 of the elevation of the entrance. And the depth of diver is equal to -15 feet.
So , the diver is at depth under water = -15 feet
Let's assume that elevation of entrance is at x foot.
So , the algebraic expression representing the depth of diver is given by :
[tex]\frac{2}{3}[/tex] × x - 1 = -15
Solving for the value of x or the elevation of entrance we get :
[tex]\frac{2}{3}[/tex] x = -15 + 1
[tex]\frac{2}{3}[/tex] x = -14
2x = -14 × 3
x = -42 / 2
x = -21 feet
Thus , the elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.

y = 3x - 5
y = -2x + 10
Answer: x=3
y=4
Step-by-step explanation:
since both equations equal y then you can just make them equal
so 3x-5=-2x+10
3x=-2x+15
5x=15
x=3
y=3(3)-5
y=9-5
y=4

Answer:
-2k
Step-by-step explanation:
Answer:
5
To find:
k
Step-by-step explanation:
-5 (3 + 4k) = -115
-5 × 3 + -5 × 4k = -115
-15 - 20k = -115
-20k = -115 + 15
-20k = -100
k = -100/-20
k = 5

What unit is used to measure the density of a solid??
Answer:
Grams per cubic meter or g/cm3
Step-by-step explanation:
The answers vary, but they have the same format which is
density = mass/volume
For instance, if the mass is in grams and the volume is in cubic centimeters, then the density would be in grams/cm^3, where "cm^3" is the abbreviation of "cubic centimeters". We can read "grams/cm^3" out as "grams per cubic centimeter"
In the accompanying diagram of a parallelogram
ABCD ,DC= 5x-18, BC=3x-6, AB=2x+12 find measure BC. Please help
Answer:
BC = 39
Step-by-step explanation:
Given:
DC = 5x - 18,
BC = 3x - 6,
AB = 2x + 12
Opposite sides of a parallelogram are equal.
Therefore:
AB = DC
2x + 12 = 5x - 18
Collect like terms
12 + 18 = 5x - 3x
30 = 2x
Divide both sides by 2
15 = x
x = 15
BC = 3x - 6
Plug in the value of x
BC = 3(15) - 6 = 45 - 6
BC = 39

(c) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm. There exist two circles of center A and tangent to (c). Construct these circles; calculate their radii
Given :
C) is a circle of center O and radius R=2 cm, and A is a point such that OA=3 cm.
There exist two circles of center A and tangent to (C).
To Find :
The radius of the new circles.
Solution :
Since, OA is 3 cm .
So, first circle with tangent to C if centre is at A is OA itself.
First radius, r = 3 cm.
And second circle is the on with radius , R = 3 + 2 = 5 cm.
Therefore, the radius of both the circles are 3 cm and 5 cm.
Hence, this is the required solution.

7) 2.1x + 45.2 = 3.2 -8.4x
Answer:
x=-4
Step-by-step explanation:
brainliest please
Answer:
x=-4, Give brainliest please
Step-by-step explanation:
Step 1: Add 8.4x to both sides.
2.1x+45.2 = -8.4x +3.2
+8.4x +8.4x
10.5x+45.2=3.2
Step 2: Subtract 45.2 from both sides.
10.5x + 45.2 = 3.2
-45.2 -45.2
10.5x=−42
Step 3: Divide both sides by 10.5.
[tex]\frac{10.5x}{10\\}[/tex]=[tex]\frac{-42}{10}[/tex]

On the coldest day of the year, the temperature at noon was 11℉. By midnight, the temperature had decreased by 15.5℉. What was the temperature at midnight? *
Answer: -4.5 ℉
Step-by-step explanation:
Given: On the coldest day of the year, the temperature at noon = 11℉
By midnight, the temperature had decreased by 15.5℉.
i.e. The temperature at midnight = Temperature at noon - 15.5℉
= 11℉ - 15.5℉
= (11-15) ℉
= -4.5 ℉
Hence, the temperature at midnight was -4.5 ℉.
When finding the slope of the trend line, what does the slope mean about the data of the scatterplot? Explain.
Answer:
So the slope on a scatterplot is almost always an estimate, so its not exact. It is just an estimate on where it might go and what might happen t data in the future.
Answer:
The slope of the trend line is the rate of change of the data. It is the ratio of the change of the dependent variable to the rate of change of the independent variable. Slope represents the value of the correlation.
