Step-by-step explanation:
1/2×base×height
1/2×9×12= 54
You need 375g for 30 cakes.
150g/12 = 12.5g
12.5g x 30 = 375g
For 7x3 and 28x2
Are those x’s multiplication? Or just an X
Answer: Phil has 33 dimes, and 17 nickels
Step-by-step explanation:
Let number of nickels be X, and dimes be Y.
X + Y = 50.
Since nickels stand for 5 cents, or 0.05 dollars, and dimes are 10 cents, or 0.10 dollars, we can also write the total worth as:
0.05*X + 0.10*Y = 4.15
Multiply this last equation by 20:
20*0.05*X + 20*0.10*Y = 20*4.15
Simplify:
X + 2*Y = 83
Subtract the first equation (X + Y = 50) from this one:
Y = 33.
Thus Phil has 33 dimes, and 17 nickels.
