Answer:
f = 11
Step-by-step explanation:
X = dryer
(X+79) = washer
X + (X+79) = $1029
Therefore, x+x+79= 1029 or 2x+79=1029
Solve for x
2x = 1029-79
2x = 950
2x/2 = 950/2
X= $475 The price of the dryer is $475
Factors of 36 that differ by 9 are 12 and 3;
<span>12*3 = 36 </span>
<span>Or you could write x(x - 9) - 36 = (x - 12)(x + 3) = 0 </span>
<span>The number was 12</span>
To find the greatest common factor, first find the largest evenly divisible number that you can take out in both numbers, in this case 15 and 25. Then find the greatest or highest number of each variable that you can evenly take out or divide in both terms, this is for a, b and c.
So GCF of 15 and 25 would be 5
GCF of a = a^1 or a
GCF of b = b^1 or b
GCF of c = c^1 or c
Put everything together to find the GCF.
GCF = 5abc.
The answer
X'Y' and XY are parallels, measX'Y'T = measXYT, there is similarity between the two triangles, we can find YT by using theorem of thales,
it is TY' / TY =TX' / TX =X'Y' /XY, so TY' / TY = TX' / TX = 9/ TY =6/ 2+6=6/8
and then 9/ TY = 6/8 therefore TY= 12
