Solve 20 ➗ 2(4+1) = ?
1. Remember to use PEMDAS- the first step in this problem is to solve what is inside the parentheses 20 ➗ 2(5) = ? 20 ➗ 10 = ? 3. Then, solve from left to right 2
Which of the following is an example of a verb? A. Red B. Up C. Walk D. Dog
We know that a verb is a word that shows action. Because of this, we can already eliminate "red" and "dog" as those words are nouns, and do NOT show action. Some kids might get stuck between "up" and "walk", but remember: "Up" is a preposition, not an action word. (Use the sentence: The squirrel ran ___ the tree; if your word can fit in the blank and the sentence makes sense, it most likely is a preposition or an adverb and NOT a verb)
Given X - 2Y - 8 = 0 and X + Y = 5, solve for X and Y
1. One way you can solve this problem is using the substitution method. Begin by solving for one of the variables (using either of the two equations given) X = 2Y + 8 2. Now that you "know" X, plug this into the other equation, simplify, and solve for Y (2Y + 8) + Y = 5 3Y + 8 = 5 3Y = -3 Y = -1 3. Finally, use your answer for Y to find X (using either of the two equations given) X = 2(-1) + 8 X= 6
