Use the order of operations to solve an expression.

10×12-14÷2+15​

128

Step-by-step explanation:

use PEMDAS

10×12-14÷2+15

multiply first

120-14÷2+15

divide next

120-7+15

now solve left to right

113+15

128

10*12=120,,14/2=7 so 120-7+15=128

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
