What is the algebraic expression to represent y less than twenty Y - 20Y + 2020 +20 - y2. 5(x + 2) + y(x + 2) (2x)(5 + y)5x + 10 + xy + 2y10x-4y(x + 2)(5 + y)3. Simplify; 2x + 5y - 7x + 8y 9x + 13y-5x + 3y5x + 3y-5x + 13y4. Divide y³ - 2y² - 5y + 6 by (y - 1)y² - 7y + 6y² - 5y - 6y²- y - 6y² - 5y + 65. 7(y + 1) - x(y + 1)7y-x(y + 1)(7 - x)(y + 1)(7x)7y + 7 - xy - x6. If xy + 1 = y² and z = 1/x - 1/xy, express z in terms of y1/ x-y1/ y+11/ y-11 + y7. Simplify (12x - 7y) + (6y + 3x)15x + 13y15x - y12x - y15x - 13y8. Make z the subject of formulasx(y + z) + 5/a -2 = 0z = 2a -5 -y/ axz = 2a -5 -axy/ axz = 5 -2a -axy/ axz = 5 -2a -y/ ax9. Simplify ^{(a² - b²)}/_{(a + b)}(a + b)(a - b)a + b(a + b)/(a - b)(a - b)/(a + b)a - b10. Simplify the expression: (3a + b) - (2a - 2b)5a - 3ba - 3ba - ba + 3b5a + 3b11. Express z in terms of x and y in the equationz = x²y²/ 2-xyz = xy²/ 2-y²z = x²y/ 2-x²z = x/ y(2-x)12. -3(x + y) + 5(x - y)-2x + 2y8x - 8y2x - 8y2x - 8y13. Simplify 3a - (9a - 5b)5b - 6a12a + 5b6a + 5b-6a - 5b6a - 5b14. Simplify the expression.6m+10−10m4m+106m−4m+1016m+1015. If p varies inversely as qr/ q-r, and p = 5 when q = 7 and r = 2, then p is equal toq-r/ 14qr25(q-r)/ 14qr14(q-r)/ qr14(q-r)/ 25qr16. 6b × 4b28b²75b²24b²84b²36b²17. Expand (3x + y + 7)(x² - 4y + 5)3x³ + x²y - 12xy +7x² + 15x - 4y² - 23y + 353x³ + x²y - 11xy +7x² + 15x - 4y² - 28y + 353x³ + x²y - 12xy +7x² + 15x - 4y² - 23y + 353x³ + 2x²y - 12xy +7x² + 15x - y² - 23y + 3518. The quantity Q varies inversely as p; p varies directly as the square root of r, and r varies directly as 1/t².ThenQ varies inversely as tQ varies inversely as t²Q varies directly as t²Q varies directly as t19. X varies inversely as y and y varies directly as t². Find the relationship between X and t given that t = 7 when X = 298Xt² = 1Xt² = 98X = 98t²X = t²/9820. 54x²y ÷ 3xy22y24x24xy18y18x21 out of 20Time is Up! Time's up
