Let the numbers be a and b, then ab=0.2 and a/b=0.8, so a=0.8b. Therefore, 0.8b^2=0.2 and b^2=0.2/0.8=2/8=1/4 and b=+1/2 or +0.5 and a=+0.8*0.5=+<span>0.4. The two numbers are therefore 0.5 and 0.4 or -0.5 and -0.4. The quotient is 0.4/0.5</span>
26*25*24*23*22*21*20*19 which is 62,990,928,000 strings.
Answer:
no
Step-by-step explanation:
Answer:
y = - 49
Step-by-step explanation:
Given
7x - 2y = 35 ← substitute x = - 9 into the equation
7(- 9) - 2y = 35, that is
- 63 - 2y = 35 ( add 63 to both sides )
- 2y = 98 ( divide both sides by - 2 )
y = - 49
Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
