This is a standard relationship/systems of equations question. Here is how you attack it. Firstly, set up equations to represent the relationships. Ed = 4*Kim That shows that Ed has four times as many pins as Kim. Next, we see that the two have 25 together. So: Ed + Kim = 25 Now we have our two equations. In order to solve, we need to get one of the equations down to one variable. We can achieve this via substitution. The first equation tells us that we can substitute 4*Kim for Ed (in the second equation). So, let's do just that: 4*Kim + Kim = 255*Kim = 25Kim = 5 Using the first equation again, we can solve for Ed: Ed = 4*KimEd = 4*(5)<span>Ed = 20</span>
What is step 4??? What is the statement?
Answer:
<u>-4</u>
Step-by-step explanation:
(4 minus 2) cubed minus 3 times 4?
The algebraic expression for the required is (4 - 2)³ - 3 * 4
According to <u>PEMDAS </u>
calculate the process at the Parentheses first the the exponent then multiplication
So,
(4 - 2)³ - 3 * 4 = (2)³ - 3 * 4 = 8 - 3 * 4 = 8 - 12 = -4
