This is a multiplication equation. So to solve for y, we must divide.
6.3/0.9 = 7
y = 7

Answer:
2,322,775
Step-by-step explanation:
By the formula of sum of an Arithmetic Sequence
![S_n= \frac{n}{2} [2a_1+(n-1)d]\\\\S_{650}= \frac{650}{2} [2\times 4+(650-1)\times 11]\\\\S_{650}= 325 [8+649\times 11]\\\\S_{650}= 325 [8+7,139]\\\\S_{650}= 325\times 7,147\\\\\huge \red {\boxed {S_{650}=2,322,775}}](https://tex.z-dn.net/?f=%20S_n%3D%20%5Cfrac%7Bn%7D%7B2%7D%20%5B2a_1%2B%28n-1%29d%5D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3ES_%7B650%7D%3D%20%5Cfrac%7B650%7D%7B2%7D%20%5B2%5Ctimes%204%2B%28650-1%29%5Ctimes%2011%5D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3ES_%7B650%7D%3D%20325%20%5B8%2B649%5Ctimes%2011%5D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3ES_%7B650%7D%3D%20325%20%5B8%2B7%2C139%5D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3ES_%7B650%7D%3D%20325%5Ctimes%207%2C147%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%5Chuge%20%5Cred%20%7B%5Cboxed%20%7BS_%7B650%7D%3D2%2C322%2C775%7D%7D%20)
Answer:
4762 N/m^2
Step-by-step explanation:
Find area.
30x5.6=168
Convert to m^2
168cm^2=0.0168m^2
Use pressure formula to get answer
P=F/A
P=80/0.0168
P=4762 N/m^2
Let x be that number.
9x must be the same as x+56:

.
We substruct x from both sides:

and we divide by 8 in both sides of the equality:
