If she has 30 cupcakes and divides them into fourths, that means that for every cupcake, she no longer has one whole piece, but 4 partial pieces. That means that that amount of 30 cupcakes will be multiplied by 4.
Answer:
x=2.4
Step-by-step explanation:
as the 2 triangles are similar,
therefore ;
Answer:
y=2 x=5
Step-by-step explanation:
3x-2y=11
2x-3y=4
you multiply both equations to cancel one variable out. in this case you multiply the first equation by 2 and the second by -3
6x-4y=22
+ -6x-9y=12
--------------------------
0x+5y=10
y=2
you plug that in either equation
3x-2(2)=11
3x-4=11
3x=15
x=5
Answer:
lets suppose initial rate of interest we need to find =x
total rate of interest as 1.5x (50%+ (consider 9% as)100%)in decimal it will be 1.5
Total rate of interest = current rate of interest
1.5x=9%
initial rate of interest x= 9/1.5 =6 Answer
to check you can calculate 50% of 6 which will be 3 and later verify
