Answer is 13 i hope this helps like it
Explanation:
"Five times" means
5
(
...
)
,
"the sum of a number, say
x
, and
−
3
", means"{(x+(-3)}=(x-3)#.
Taking all these together, the reqd. Algebraic Expression turns out to be
5
(
x
−
3
)
.
75(2)+.20x=238
You then solve for x by multiplying 75 by 2 to get 150. Then subtract 150 from both sides of the equation, so this is what you get .20x=88. Finally divide by .20 on both sides to get x= 440
Answer:
You write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
Step-by-step explanation:
so for example, .005 would be 5x10^-2 and 500 would be 5x10^2
To find the answer you have to use pythagorean theorem;
a² + b² = c² where a and b are the legs and c is the hypotenuse.
5² + 15² = c²
25 + 225 = c²
250 = c²
√250 = √c²
√250 = c
