Answer: 0.40 = x
Step-by-step explanation:
3x + 13 = 7x - 15
15 - 13 = 7x - 3x
2 = 5x
2/5 = x
0.40 = x
Answer:
-(2/5)^3 or -8/125 or -0.064
Step-by-step explanation:
convert the decimal into a fraction
then use your calculator to find the exact answer
The answer is -6x^2 + 7x, or answer choice A.
10 because 5×2 is equal to 10
A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
