10 is the base. If you get stuck on anymore problems like this you can tell which one is the base by looking where the exponent is in the problem. Hope this helps!!
Answer:
200
Step-by-step explanation:
The unknown number = x
25% of x = 50
25% of x = 0.25x
0.25x = 50
Multiply both sides of the equation by 4
x = 200
Hope this helps :)
Answer:
It can either be rational or irrational
Step-by-step explanation:
Given the quadratic equation ax²+bx+5 = 0, to get the zeros of the function, we will factorize the function to have;
ax²+bx = -5
x(ax+b) = -5
x = -5 and ax+b = -5
From the second function we have;
ax+b = -5
ax = -5-b
x = -5-b/a
This shows that the other value of x can be rational or irrational depending on the values of a and b
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4
I’m not 100% sure but isn’t it x2 +xy +y2?
