X = 5
Y = 6
Simply we just compare the two shapes and we can see that 6 decreases to 4..so we would assume the rest would decrease by 2. If we were not so sure we could simply do a^2 + b^2 = c^2 and fill in the numbers

Tonia and trinny are twins. Their friends give them identical cakes for their birthday. Tonia eats 1/8 of her cake and trinny ea

Nikitich [7]

Answer:

$\frac{7}{12}$ of the cake

Step-by-step explanation:

add $\frac{1}{8}$ and $\frac{1}{6}$ to see the total amount of cake eaten.

a. find the common denominator: 8 x 3 = 24 and 6 x 4 = 24

b. multiply accordingly to get the correct numerator: $\frac{3}{24}$ + $\frac{4}{24}$

c. add: $\frac{3}{24}$ + $\frac{4}{24}$ = $\frac{7}{24}$

subtract found value from total to find left over cake.

a. 24 - 7 = 14

simplify.

a. $\frac{14}{24}$ = $\frac{7}{12}$

You are left with $\frac{7}{12}$ of the cake.

Write a polynomial to represent the value of d dimes and n nickels.

nadya68 [22]

Answer: 0.10d + 0.05n
Note: this value expression is in dollars (not cents)
If you want the expression in cents instead of dollars, then it would be 10d+5n

--------------------------------------------------------------------------------

The value of just the dimes only is 0.10d dollars
The value of just the nickels only is 0.05n dollars
Combined the total value is 0.10d+0.05n dollars
