Answer:
276 is equal to 30%.
Let x miles to drive to get his destination.
Thus, remained 70%.
276/x = 30/70
X = 644 miles to go.

Step-by-step explanation:
(-2a² + s)(5a² - 6s)
= (-2a²)(5a²) + (-2a²)(-6s) + (s)(5a²) + (s)(-6s)
= -10a⁴ + 12a²s + 5a²s - 6s²
= -10a⁴ + 17a²s - 6s². (1st option)
Ok so whit the data that we got we can proceed like this:
[(-2, 7), (1, 0)]
d = 2/3
Now lets find the difference between x and y terms.
The difference of -2 and 1 is 3,
The difference of 7 and 0 is 7.
x = 3
y = 7
Now Multiply it by two thirds.
2/3 * 3 = 2
2/3 * 7 = 4.7
So the answer is the second option. Hope this helps

150 since rectangle has 4 sides, so 600 is divided to 4(sides)=150
Step-by-step explanation:
what's the question ? it does not say.
I assume it is "how many packages of what size were sold ?"
x = number of small packages
y = number of medium packages sold
z = number of large packages sold
x + y + z = 9
7x + 12y + 15z = 86
y = 3z
these are the 3 equations we get out of the question.
we put the third equation into the other two :
x + 3z + z = x + 4z = 9
7x + 12×3z + 15z = 7x + 36z + 15z = 7x + 51z = 86
it of this first equation we get
x = -4z + 9
and putting that into the other equation :
7×(-4z + 9) + 51z = 86
-28z + 63 + 51z = 86
23z = 23
z = 1
y = 3z = 3×1 = 3
x = -4z + 9 = -4×1 + 9 = -4 + 9 = 5
so, 5 small, 3 medium and 1 large packages were sold.
