Answer:
7 inches
Step-by-step explanation:
The ratio of width to length of the known rectangle is 4 : 14 and this simplifies to 2 : 7.
The smaller similar rectangle will have the same ratio of 2 :7.
This can also be looked at another way. The second value in the ratio is 7/2 of the first value in the ratio and the first value is 2/7 of the second value.
Example:
7/2 * 2 = 7
Example:
2/7 * 7 = 2
1) 13.02-6y=8y
+6y=6y
13.02=14y then divide both sides by 14. you get y= .93
2) 1/5x+5=19-1/2x
-5=-5
(1/5x=14-1/2x)5
x=70-2.5x
+2.5x=+2.5x
3.5x=70 divide both sides by 3.5 and you get x=20
3) 7.3t+22=2.1t-22.2
-2.1t =-2.1t
5.2t+22=22.2
-22=-22
5.2t=-44.2 divide both by 5.2 and t=-8.5
4) (1.4+2/5e=3/15e-.8)15
21+6e=3e-12
-3e=-3e
21+3e=-12
-21 =-21
3e=-33 divide both by 3 and e=-11
5) 5(x-4)=2(2x+5)
5x-20=4x+10
-4x -4x
x-20=10
+20=+20
x=30
6) -7(3+t)=4(2t+6)
-21-7t=8t+24
+7t=+7t
-21=15t+24
-24= -24
-45=15t divide both by 15 and t=-3
7) (3/4x+6=1/3x+9)4
3x+24=1.3x+36
-1.3x =-1.3x
1.7x+24=36
-24=-24
1.7x =12 divide both sides by 1.7 and x=7.06
