0.65 x 10 = 6.5
0.65 is 10 times as much as 6.5
6x + 4x+6 + 8x+3 = 63
6x+4x+8x = 63 - 3 - 6
18x = 54
x = 54/18
x = 3
Side AB = 6(3) = 18
Side AC = 4(3)+6 = 18
Side BC = 8(3)+3 = 27
Answer:1/30 page per minute
Step-by-step explanation:
2 1/2 pages =3/2 pages.
3/4 hrs=45 minutes
Hence the number pages he can type per minute =3/2 pages/45 minutes=3/2×1/45=1/30page per minute
Answer: 3 the actual answer is 2.995421844
Step-by-step explanation:
Figure 1 has 8 tiles
figure 2 has 14 tiles
figure 3 has 22 tiles
I'm guessing the 2 on the side hints for us to do something+2
the inside parts are
figure 1: 6
figure 2: 12
figure 3: 20
hmm, the width is 1+number figure
height is 2+figure number
so therefor, figure x is (1+x)(2+x)+2
so the rule is figure x has (x+1)(x+2)+2 or
tiles
a. the rule is figure x has (x+1)(x+2)+2 or
tiles
b. it is quadratic because it has
in it
