Multiply both sides by (3*5)
5(2n)=3(n+14)
distribute
10n=3n+42

7n=42
divide both sides by 7
n=6

I need help with this
Stells [14]

Answer:

AB = 21

Step-by-step explanation:

So we have two triangles (AEB and ADC), and they're similar by AA

Now, you can find the ratio of similitude by checking AE/AD which is 14/26 = 7/13

AB/AC = 7/13

Take AB as x aight

x/x+18 = 7/13

x=21

Simplify: 3 . 3^2 + 8 ÷ 2 - (4 + 3) A: 32 B: 24 C: 23 D: 30
yaroslaw [1]

Answer:

its none of these answers ;-;

Step-by-step explanation:

3^2 + 8 ÷ 2 - (4 + 3)

we do what's in parentheses first. (pemdas)

so now we have, 3^2 + 8 ÷ 2 - 7

next exponents, 3^2=9

9 + 8 ÷ 2 - 7

next division, 8÷2=4

9 + 4 - 7

next addition, 9+4=13

13-7

finally subtraction, 13-7=6

final answer: 6

Is 4/6 greater than 9/12
Liono4ka [1.6K]
You start by cross multiplying.
4 x 12 = 48
Therefore, the value of 4/6 is equal to 48.
You do the same on the other side.
6 x 9 = 54
Therefore, the value of 9/12 is equal to 54.

No. 9/12 is greater than 4/6.
