Answer:
-21
Step-by-step explanation:
When a=6 and x=-3 to find -a+5x, substitute the values:
-(6)+5(-3)
Remove parenthese through multiplication:
⇒ -6+(-15)
Same signs add and keep the sign:
⇒-21
Which represents the polynomial written in standard form?
8x2y2 – + 4x4 – 7xy3
<span>0.03x+20=0.07x+5 original equation
</span>0.03x+20-0.03x=0.07x+5-0.03x <span>subtract 0.03x from both sides to combine like terms
</span>20=0.04x+5
20-5=0.04x+5-5 subtract 5 from both sides
15 = 0.04x
15/0.04 = 0.04x/0.04 divide both sies by 0.04 to get x alone.
375 = x <-------WOOOOOO! theres the answer!
