Answer:
Step-by-step explanation:
Ok, this is a Linear equation so you need to find the result of k;
First you sum the two terms that include k
34k+38k=12
72k=12
Secondly, you separate the 72·K term by sending the 72 diving to the other side of the equation(remember if you have a number multiplying when yoy pass it to the other side of the equation you need to pass it dividing):
K=12÷72
Then you resolve the division:
K=
IF the problem requires it, you can simplify the number tex]\frac{12}{72}[/tex] diving both numbers by 4 and then by 3 so the final result is:
K=
The standard form using integers of the equation is 6y - x = 42
<h3>How to determine the standard form</h3>
Note that solving in standard form means writing it as a simple equation
Given y = 1/6x + 7
Find the LCM of the right side, we have
y =
Cross multiply
6 × y = x + 42
6y = x + 42
Make the variables move to the left side
6y - x = 42
Thus, the standard form using integers of the equation is 6y - x = 42

Step-by-step explanation:
Given

What is l when S = 725
This can be solved using Sum of n terms of an AP;
Where
To get T1; we substitute 4 for k in 2k - 3
To get Tn; we substitute l for k in 2k - 3
n = the number of terms;
Since k = 4 to l, then
Substitute these values in
Collect Like Terms
Open the bracket
Subtract 725 from both sides
or
or
But l must be positive;
Hence,
Answer:
about 7 cups
Step-by-step explanation:
if he uses 2 cups for 18 cookies, then he uses 1 cup for 9 cookies. the closest whole number you can get is 63 (9 x 7) so he will need about 7 cups of flour for 60 cookies. hope this helps! :)
