I think the answer is 320miles,
3hs at 60mph = 180miles
2hs at 70mph = 140miles
so 180+140=320miles
2/3x+1=5-8
Combine like terms:
2/3x+1=-3
Subtract 1 from both sides
2/3x=-4
Multiply 3x from both sides
2=-12x
Now divide -12 from both sides
=-2/12
Simplify and you get -1/6 for your answer
Here's how to find the value of x:
<span>9 - 0.75 ( x + 8 ) - 5 = -6.5 find the difference of 9 - 0.75
</span><span>8.25 ( x + 8 ) - 5 = -6.5 add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5 distribute 8.25 to x and 8
8.25x + 66 = -1.5 subtract 66 from both sides
8.25x = -67.5 divide both sides by 8.25
x = 18.18181818...... the value of x is 18 2/11
hope this helps
Answer:
y = 3x^2 + 12x + 8
Step-by-step explanation:
To rewrite in standard from by expanding the equation using the distributive property.
y= 3 (x+2)^2 - 4
y = 3(x^2 + 4x + 4) - 4
y = 3x^2 + 12x + 12 - 4
y = 3x^2 + 12x + 8
Angle WDY is= 5x+33
Hope this helps!! Have a good day!! :D
