Answer:
The value of the given expression -9w+9 when w=15 is -126
Step-by-step explanation:
Given expression is -9w+9
To find the given expression when w=15:
That is put w=15 in the given expression we get
-9w+9=-9(15)+9
=-135+9 ( adding the like terms )
=-126
Therefore the value of the given expression -9w+9 when w=15 is -126
Answer: 67204
Step-by-step explanation:
10.5 small boxes equals the same amount of cereal in a large box
<h3>
How to determine the value</h3>
From the information given, let:
n is the number of smaller boxes
We know that:
Then,
12 + 7.6n = 6 + 8n
collect like terms
8n - 7. 6n = 12 - 6
0. 4n = 6
n = 6/ 0. 4
n = 15
The amount of cereal in a large box is;
6 + 8n = 6 + 8 (15) = 126 ounces
The amount of cereal in the smaller box is 12 ounces
Divide the volume of the larger box by the volume of the smaller box;
= 126/ 12
= 10. 5 smaller boxes
Hence, 10.5 small boxes equals the same amount of cereal in a large box
The complete question:
A cereal box manufacturer changes the sizeof the box to increase the amount of cereal it contains. The equations 12 + 7.6n and 6 + 8n, where n is the number of smaller boxes, are both representative of the amount of cereal that the new larger box contains. How many smaller boxes equal the same amount of cereal in the larger box?

Answer:
My wet but, you scaliwag
Step-by-step explanation:
it simple and easy
This is the equation: 3x-2=5x+15
<span>you combine like terms: 3x-3x-2=5x-3x+15 </span>
<span>the 3x on the left cancles out: -2=2x+15 </span>
<span>subtract 15 on both sides: -2-15=2x+15-15 </span>
<span>the 15 on the right cancles out:--17=2x </span>
<span>divide by 2: -17/2=2x/2 </span>
<span>x equals negative 8.5: x=-8.5</span>
