The best answer would be D
Because Rotational symmetry is a symmetric shape that can be rotated but appear the same.
Answer:
x = 3/10
Step-by-step explanation:
−1/2 − (−4/5) = x
First, switch sides.
x = −1/2 − (−4/5)
You are subtracting a negative number. Subtracting a negative number means add a positive number.
x = -1/2 + 4/5
Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.
x = -5/10 + 8/10
x = 3/10
Answer:
-4
Step-by-step explanation:
(4-2)³ = 8
so 8 - 3 x 4
is equal to -4
'is' in mathematics means equal
'of' in mathematics means multiplication
percent means over 100
84 = 74% * x
84 = 74/100 * x
84 = 37/50 * x
Multiply 50/37 on both sides, so we can isolate 'x'
85 * 50/37 = x
x = 4250/37
x ≈ 114.864865
84 is 74 percent of <span>114.86</span>.
