Answer:
x = 2, y = 7, z = 12
Step-by-step explanation:
x + y - z = -3 (1)
3x - y + z = 11 (2)
x - 4y + z = -14 (3)
add (1) and (2)
4x = 8 x = 2
add (1) and (3)
2x - 3y = -17
2(2) - 3y = -17
-3y = -17 - 4
-3y = -21
y = 7
Find z using any equation
x + y - z = -3
2 + 7 - z = -3
9 - z = -3
z = 12
Answer:
The answer to your question is Area = 37500 ft²
Step-by-step explanation:
Data
lawn 1 lawn 2
width = 550 ft width = 250 ft
Area = 181500 ft² Area = ?
Process
1.- Find the length of lawn 1
Area = length x width
-solve for length
length = Area/width
-Substitution
length = 181 500 ft²/ 550
-result
length = 330 ft
2.- Find the length of lawn 1 using ratios and proportions
550 : 330 :: 250 : x
x = (250 x 330) / 550
x = 150 ft
3.- Find the area of lawn 2
-Substitution
Area = 250 x 150
-Result
Area = 37500 ft²
Answer:
an=-2n-3
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
The problem can be solved geometrically. By this way, the solution is going to be easy, as well.
We can see from the attached graph that the coordinates are the vertexes.
Considering a unit distance, we can find that the width of this rectangle is:
4 = 12 - 8
and the length is:
7 = 6-(-1)
Then, the perimeter is P = (4+7)*2 = 22
Answer:
.048
Step-by-step explanation:
6 thousandths = 0.006
So, 0.006 times 8 would be...
.006
<u>x 8</u>
.048
Hope this helps you out! I'm not exactly sure how to explain how to multiply, but if you're confused, you can always ask someone for help...have a great day :)
