5 or 6 years. subtract 1200 from 10000until you get 2800
Answer:
<em>16 feet</em>.
Step-by-step explanation:
Please refer to the attached diagram for the clear understanding of the given question statement.
A is the position of tour guide on deck.
B is the sea level. (Can be considered as zero on the number line)
C is the position of Diver and
D is the point on ocean floor.
Below sea level dimensions are given as negative in the question statement.
As per given statement,
AB = 5 feet
BC = 11 feet (Ignoring the negative sign as negative sign only depicts that it is below sea level)
BD = 18 feet
To find:
Distance from tour guide to the diver = ?
Solution:
We have to actually find the value of AC here as per the image attached.
AC = AB + BC = 5 + 11 = <em>16 feet</em>
Answer:
The Highest common factor of 120,140,180 is ( HCF) = 20
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given numbers 120,140,180
120 = 60 × 2
= 30 × 2× 2
= 15 × 2×2×2
= 5×3× 2×2×2
140 = 70 × 2
= 10 × 7× 2
= 5× 2× 7× 2
180 = 90 × 2
= 30×3×2
= 5 × 6 × 3× 2
= 5 × 2× 3× 2 × 3
The Highest common factor of 120,140,180 is 5 ×2×2 = 20

Hey there! I'm happy to help!
SYSTEM #1
-4x+2y=22
-y=-3x-9
We can multiply both sides of the second equation by -1 to see what y equals.
y=3x+9
We can substitute this value for y into the first equation and solve for x.
-4x+2(3x+9)=22
We use distributive property to undo the parentheses.
-4x+6x+18=22
We combine like terms.
2x+18=22
Subtract 18 from both sides.
2x=4
Divide both sides by 2.
x=2
Our x has to be -4 to be the correct answer, so this option is incorrect.
SYSTEM #2
-4x+2y=22
y=-3x-9
We plug this y value into the first equation to solve for x.
-4x+2(-3x-9)=22
We use distributive property to undo the parentheses.
-4x-6x-18=22
We combine like terms.
-10x-18=22
Add 18 to both sides.
-10x=40
x=-4
We have the correct x-value to be the answer, so let's find the y-value by plugging our x-value into one of the equations.
y=-3(-4)-9
y=12-9
y=3
So, the solution of this system of equations is (-4,3), so the correct answer is 2. -4x+2y=22, y=-3x-9
Have a wonderful day! :D
