When solving equations like these, our number one goal is to get x to be alone.
So given the equation lets go through it step by step.
3x - 5 = 10 + 7x (first step is to add 5 to both sides)
+ 5 = + 5 ( Now lets see what we have now)
3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)
-7x = -7x ( now what do we have?)
-4x = 15 (okay divide both sides by 4 to isolate the x)
÷4 = ÷4 (now the 4's on the left side cancel out, and we solve on the right side)
x = 3.75
That's your answer :) Good Luck!
Answer:
The correlation between sales and advertising is positive.
Step-by-step explanation:
For every $35 spent on advertising, sales increase by $1
Is FALSE, since y = 500 + 35 x $35, sales increase more than $1
Even if no money is spent on advertising, the company realizes $35 of sales
Is FALSE, if no money is spent, the sales amount to $ 500 (when X = 0)
The coefficient of correlation between sales and advertising is 0.81
Is FALSE, since R² = 0.9. The coefficient of correlation = R = 0.94, not 0.81
If u think of it this way
8*4=32 it has to be smaller than that so my best guess would be
C) 20 square units
Answer:
659.1
Step-by-step explanation:
6.591 * 100
=> 659.1 (We can just move the decimal point 2 places to the left because this is multiplication)
This is the same pattern used in all of the questions,
Pattern - Multiplying by powers of 10, which results in shifting of decimal places
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Answer:
155
Step-by-step explanation:
a triangle all add up is 180
subtract 180 from 65
180-65=155
x=155
