Answer:
15 14/15
Step-by-step explanation:
8 + 7 = 15
1/3 + 3/5
5/15 + 9/15
14/15
15 + 14/15 = 15 14/15
Y - 6 = -3/7(x + 5)
y - 42/7 = -3/7x - 15/7
y = -3/7x + 27/7
3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97
or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97
4x-35=9x
-4x
-35=5x
divide by 5
x= -7
