Answer:
50
Step-by-step explanation:
1. Plug in what you know, if t=5 and u=10 replace the variables for their corresponding numbers.
2. 5(10)=50
9514 1404 393
Answer:
Step-by-step explanation:
Let 'a' and 'p' stand for the prices of apple and pumpkin pies, respectively. Then the two sales are described by ...
4a +5p = 86
8a +2p = 92
Subtract half the second equation from the first to eliminate the 'a' variable.
(4a +5p) -(1/2)(8a +2p) = (86) -(1/2)(92)
4p = 40 . . . . . simplify
p = 10 . . . . . . . divide by 4
Substitute into the first equation:
4a + 5(10) = 86
4a = 36 . . . . . subtract 50
a = 9 . . . . . . . divide by 4
One apple pie costs $9; one pumpkin pie costs $10.
Y=3/2x+7/2 hope this helps!
Answer:
10 square units
Step-by-step explanation:
Because to get the area of a triangle you cut the base length in half then multiply it by the height, in this case 2.5*4 = 10 square units
