<h2>Maneuvering an equals sign</h2><h3>Concept</h3>
Learn the rules and implications of moving numbers across an equals sign to combine like terms.
<h3>Utilization</h3>
When you move a negative number across an equals sign (in incredibly linear equations), you should always add it, the inverse (subtract) goes for positive numbers.
<h3>Answer</h3>
x = -11
Answer:
Let x = the number or green sweets
Let x + 8 = the number of red sweets
red/green: (x + 8)/x = 5/3 Cross multiply
5x = 3(x + 8)
5x = 3x + 24
2x = 24
x = 12 green sweets
Answer:
0+(-2)+9=7
Step-by-step explanation:
You start at 0 then go down by 2 or minus by , Then add by 9 then you end up at 7.
Answer:
-7 goes in the box
Step-by-step explanation:
x^ -3 = x^4 * x^n
We know that a^b * a^c = a^ (b+c)
x^-3 = x^(4+n)
When the bases are the same the exponents are the same
-3 = 4+n
Subtract 4 from each side
-3 -4 = 4+n-4
-7 = n
Answer:
2, 3, and 4
Step-by-step explanation:
To determine if the given sides make a triangle, the sum of any two sides should be greater than the third.
<h3>a) </h3>
4, 7, and 13
4 + 7 > 13
<h3> 11 > 13 FALSE</h3><h3>b)</h3>
9, 13, and 23
9 + 13 > 23
<h3> 22 > 23 FALSE</h3><h3>c)</h3>
2, 3, and 4
2 + 3 > 4
<h3> 5 > 4 TRUE</h3><h3>d)</h3>
10, 10, and 30
10 + 10 > 30
<h3> 20 > 30 FALSE</h3>
