First calculate (-8x-15)=120
Then multiply - 11x120
=-1320
X + 9 = 16
explanation : he bought nine more coins which made it 16. to find out how many coins he sold you would solve the equation then divide by 2.
Answer:105
Step-by-step explanation:
becasue you can mutiply 35 3 times and 21 5 times and you get the same number as 105
Answer:
5/4 or 1.25
Step-by-step explanation:
-5/3 x -3/4
apply the fraction rule
-5/3 = 5/3
apply the same rule to -3/4
= 5/3 x 3/4
cross cancel common factor which is 3
and you will get 5/4
Answer:
B. 3
Step-by-step explanation:
First of all we will define rotational symmetry.
Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.
The order of rotational symmetry is how many times it matches the original shape during the rotation.
So, for the given shape the rotated shape will match the original shape three times so the order for symmetry for the given shape is 3.
Hence,
the correct answer is B. 3 ..
