Answer:
Equation: 2x + 1 = 9x - 13
There are two chairs in each row.
Step-by-step explanation:
Looking at the problem, we see that Hue can form two rows of chairs with 1 left over, or 9 rows if she gets 13 more. With that information we can create the equation 2x + 1 = 9x - 13. Now let's solve for x.
2x + 1 = 9x - 13
<em>What we can do first is subtract 9x from both sides. This is done so all of the variables are on one side. Thus that becomes...</em>
2x + 1 - 9x = -13
<em>Now, combine -9x and 2x to get -7x.</em>
-7x + 1 = -13
<em>Now subtract 1 from both sides. This is done so we solve for x directly.</em>
-7x = -13 - 1
<em>Subtract -1 from -13 to get -14.</em>
-7x = -14
<em>Now divide both sides by -7.</em>
x = -14/-7
<em>Divide -14 by -7 to get 2. Remember, dividing two negatives gives you a positive!</em>
x = 2
With that, the equation is solved. There are 2 chairs in each row.
Answer:
90
Step-by-step explanation:
Let the starting number be x, the two consecutive numbers after x is gonna be x+1 and x+2.
If the sum of these three numbers is 267 then:
x+(x+1)+(x+2)=267
Solve
3x+3=267
3x=267-3
3x=264
x=264/3
x=88
x+1=89
x+2=90
Your three consecutive numbers are 88, 89, and 90.
The largest one of them is 90.
We name angles in three different ways:
(1) We can name angles by using THREE capital letters like: ABC or DEF. The middle letter is called the VERTEX of the angle. The above angles are read "angle ABC" and "angle DEF." This leads us to the second way we can name angles.
(2) We can name angles by using the vertex. For example, ABC, can also be called angle B; the same applies to DEF (we can call angle DEF angle E). Of course, if there's more than one angle sharing the same vertex this would be confusing!
(3) We can also name an angle by placing any number or symbol at the vertex in the INTERIOR of the angle. So, angles can also be called angle 1 or angle 2 or angle 4, etc.
