Answer:
2/5, 8/20, 4/10,16/40
Step-by-step explanation:
40%
Percent means out of 100
40/100 = 4/10 = 2/5
Lets look at the choices
8/100 =4/50 =2/25 not equal
2/5 equal
8/20 = 4/10 =2/5 = equal
4/10 = 2/5 = equal
16/40 = 4/10 = 2/5 equal
q= -1/2
perpendicular slopes are those that are opposite sign and reciprocal of the original given slope

Answer:
Assuming the other side is 30, x=12
Step-by-step explanation:
X+(X+6)=30
2x+6=30 (open the brackets by distributing the plus sign inside)
2x=24 (subtract 6 from both sides)
x=12 divide both sides by 12
This makes sense because of x is 6, and x+6 is 18, 6+18=30.
Answer:
The dimensions are <u>15 x 6</u>
Step-by-step explanation:
Length (L) Width (W)
Perimeter = (W x 2) + (L x 2)
L = (W x 2) + 3
L x 2 = (W x 4) + 6
42 - 6 = 36
36 ÷ 6 = 6
6 x 2 + 3 = 15
<u>Perimeter = (6 x 2) + (15 x 2) = 42</u>
