In the given figure, if a:b=10:13, then /_xoy equals.

soldier1979 [14.2K]

Answer:

2x + 7 = 3x - 7

3x - 2x = 7 + 7

x = 14

2x + 7 + 12y + 1 = 180

2(14) + 12y + 8 = 180

28 + 12y + 8 = 180

36 + 12y = 180

12y = 180 - 36 = 144

y = 144/12 = 12

x = 14, y = 12

$\bf A=5280\left[ \cfrac{\left( 1+\frac{0.06}{1} \right)^{1\cdot 4}-1}{\frac{0.06}{1}} \right]$

Joe is making $485 payments monthly, but the amount gets interest on a yearly basis, not monthly, so the amount that yields interest is 485*12

also, keep in mind, we're assuming is compound interest, as opposed to simple interest

From the set {6, 7, 11}, use substitution to determine which value of x makes the equation true.

kotykmax [81]

11 if you multiply 11 by both the number and and the variable you’ll get 11x-55=66. Add 55 to each side which will give you 121 then divide that by 11
