if 18=x/10000 then x=? (answer)

R = C/(X/1000) Solve for X R = C (1000/X) multiply by the reciprocal R = 1000C/X RX = 1000C Multiply both sides by X. X = 1000C/R X = (1000)(12)/3.028139 X = 3,962

Solve the first equation for y: 3x + 2y = 4 2y = 4 - 3x y = (4 - 3x ) / 2 Substitute (4 - 3x) / 2 for y in the second equation. 5x - 4[(4 - 3x) / 2] = 3 5x - 2(4 - 3x) = 3 5x - 8 + 6x = 3 11 x = 11 x = 1 Use this value for x to solve...

(c-25)(c+50)=0 (answer)

This equation has two answers. Any real number times 0 equals 0. This is called the zero property of multiplication. Therefore either (c-25) has to equal zero, or (c+50) has to equal zero. SOLUTION: (c-25)(c+50)= 0 (c-25) = 0 C-25+25 = 0+25 (add...

0=-1500000+97000/(11%-g) (answer)

0 = -1,500,000 + 97,000/.11-g 0=.11-g/.11-g(-1,500,000 + 97,000/.11-g) remove the fraction be multiplying by .11-g/.11-g 0=-1,500,000(.11-g) + 97,000 0 = -165,000 + 1,500,000g + 97,000 distributive property -1,500,000g = -165,000 + 97,000 ...
