Answer:
Step-by-step explanation:
3a + b
a = 1.4 - 2x
b = -0.2x + 1.7
3 ( 1.4 - 2x ) + -0.2x + 1.7
= 4.2 - 6x - 0.2x + 1.7
= 4.2 + 1.7 - 6x - 0.2x ( by rearranging the like terms )
= <u><em>5.9 - 6.2 x</em></u>
hope this helps
plz mark as brainliest!!!!!!!!
Answer:5.9-6.2x
a=1.4-2x
b=-0.2x+1.7
3a+b
=3(1.4-2x)+(-0.2x+1.7)
=4.2-6x-0.2x+1.7
=4.2+1.7-6x-0.2x
=5.9-6.2x
(x - 8)/2 = -5
x - 8 = -10
x = -2
(y + 6)/2 = 10
y + 6 = 20
y = 14
(-2, 14)
3 x x
