For 2-4 use mental math strategies to solve 9,100-2,130+990

7960

Step-by-step explanation:

PEMDAS is irrelevant since they are all addition and subtraction. You can first to 9100+990 in your head which equals 10,090. Then you can subtract 130 in you head which equals 9960. Then you subtract the final 2,000 which results in 7960.

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.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
