Answer:
m=-1/2
Step-by-step explanation:
m=y2-y1/x2-x1
m=8-5/-2-4
m=3/-6
m=-1/2
Answer:
So, the original space of her garden was 20ftl + 4ftw. This makes her garden have a starting area of 80ft.
She then adds another 72ft (12ftl x 6ftw) which brings the total area to 152ft.
We have 152ft to work with here, if she wants to use 100 of those ft for vegetables, and the rest to plant fruits, we have to subtract 100 from 152 which gives us 52.
Answer:
The Fruits will take up 52ft of land.
Hope this helped!
Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
Answer:
cos(L) = 12/13
Step-by-step explanation:
The hypotenuse of the triangle is LM = 13. The side adjacent to angle L is LN = 12. (It has L in the name.) The cosine is the ratio of the adjacent side to the hypotenuse:
Cos = Adjacent/Hypotenuse
cos(L) = LN/LM
cos(L) = 12/13
Answer:
x = -1
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
5x - (x + 4) + 1 = 3 - 2(x + 6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5x - x - 4 + 1 = 3 - 2x - 12
- Combine like terms: 4x - 3 = -2x - 9
- Add 2x on both sides: 6x - 3 = -9
- Add 3 to both sides: 6x = -6
- Divide both sides by 6: x = -1
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)
- Parenthesis (Add): 5(-1) - 3 + 1 = 3 - 2(5)
- Multiply: -5 - 3 + 1 = 3 - 10
- Subtract: -8 + 1 = -7
- Add: -7 = -7
