1. 1m=100 cm
1m^2= 10,000 cm^2
2. if 3 pencils are 1.65, then 1 pencil is 1.65/3=$ 0.55
7 pencils will cost 7* $0.55= $3.85
3.1 ha is 10,000 m^2, and 1 soccer filed is roughly 100m *110 m
so it makes sense that 1 ha is roughly 2 tennis courts
4.odd numbers between 20 and 30 are
21,23,25,27,29
lets add the,m
21+23+25+27+29=125
5 a rhombus has 2 lines of symmetry
Answer:
- 7/8
Step-by-step explanation:
m = Δy/Δx = (10-3)/(2-10) = - 7/8
The like terms are 12 and 5, so you have to subtract 5 from both sides.
12 < x + 5
-5. -5
7 < x
We can just switch it around so x is in the left side.
x > 7
Answer:
<em><u>D</u></em>
Step-by-step explanation:
take two points from the graph to find the slope
(0,2) and (10,14)
m=(y2-y1)/(x2-x1)
m=(14-2)/(10-0)
m=12/10
<em><u>m</u></em><em><u>=</u></em><em><u>6</u></em><em><u>/</u></em><em><u>5</u></em>
now take only one point from the graph to make a graph equation
(0,2) let us use this
m=(y2-y)/(x2-x)
m=(2-y)/(0-x)
m=(2-y)/(-x)
6/5=(2-y)/(-x)........... m=6/5
-x6/5=2-y
(-x6/5)-2=-y
-(-x6/5)(-2)=-(-y).....multiplying both sides by negative to make y positive
<em><u>Y</u></em><em><u>=</u></em><em><u>x6</u></em><em><u>/</u></em><em><u>5</u></em><em><u>-2</u></em>
