Answer:

So his allowance is 25 dollars

6.50 dollars he used to buy the banana splits which is 26%

Step-by-step explanation:

So 3.25 for 1 banana splits

then for 2 its 2 × 3.25 = 6.50 dollars

So 26% of a number let say n is 6.50 dollars

26/100 × n = 6.50

0.26 × n = 6.50

n = 6.50/0.26

n = 25

So his allowance is 25 dollars

6.50 dollars he used to buy the banana splits which is 26%

-7 x - 2y = -13 <br> x - 2y = 11
VashaNatasha [74]
Well the first one would convert to
-2y= 7x-13 and the second one would be -2y=-x+11 and you solve from there (lmk if you need the steps) but your final answer would be. Y= -7/2x+ 13/2 and y=1/2x - 11/2

if you add the digits in a two-digit number and multiply the sum by 7, you get the original number. If you reverse the digits in
ANTONII [103]
Let m the tens digit and n the ones
the Original number is 10m+n
7(m+n) =10m+n
7m+7n=10m+n
6n=3m

Reversing the number 10n+m
10n+m=18+n+m
9n=18
n=2

6n=3m
6(2)=3m
3m=12
m=4
the number is 10m+n=10(4)+2=42
