Alright! 

To simplify <em>4 + 6(7x + 7), </em>we must combine like terms. Right off the bat, we can see what we have to do thanks to the order of operations. 

<em>* original equation
</em><em>4 + 6(7x + 7)
</em>
<em>* alright, so - since we can't do anything in the parenthesis, we now have to see what we can do multiplication wise.
</em><em>4 + 42x + 42
</em>
<em>* alright, so we could multiply the two 7's by 6, but now what? well, we can't do anything else to the 42x because of the variable, so we have to now add 4 and 46!
</em><em>
</em><em>and our simplified equation is... 42x + 46! =)</em>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Budget for education is $ 660.4 billion less than budget for defense in some country

x = represents the budget for education, in billion of dollars

2. How can the budget for defense be​ represented?

x = represents the budget for education, in billion of dollars

x + 660.4 = represents the budget for defense, in billion of dollars also

paco has 75 minutes before he needs to get ready for baseball practic.he cleans his room for 40 minutes and reads and reads for
fomenos
By the way this problem is worded, he spends 75 minutes reading and cleaning, but there seems to be not enough information because the way it is worded, it means he has 75 minutes until he needs to GET READY, not play in the actual game. (40 + 35 = 75).

Write the equation for the line whose slope is -1/4 and goes through the point (-2,6)​
Kryger [21]

Answer:

y = -\frac{1}{4} + \frac{11}{2}

Step-by-step explanation:

use y = mx + b where:

y = y-coordinate = 6

m = slope = -1/4

x = x-coordinate = -2

b = y-intercept = what we're solving for to complete the equation

plug the values into the equation

6 = -\frac{1}{4}(-2) + b               multiply -\frac{1}{4} and 2

6 = \frac{1}{2} + b                         subtract \frac{1}{2} from both sides

b = \frac{11}{2}

now we plug m and b into the equation and leave x and y as variables to get the final equation:

y = -\frac{1}{4} + \frac{11}{2}
