Answer:
3x + 1 = 7
Step-by-step explanation:
3x + 1 = 7 <em>Subtract</em><em> </em><em>1</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>
3x = 6 <em>Divide</em><em> </em><em>3</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>
x = 2
5 consecutive even integers: n, n+2,n+4,n+6,n+8
n+(n+2)+(n+4)+(n+6)+(n+8)=1310
combine like terms
5n+20 = 1310
subtract 20 from each side
5n = 1290
divide by 5
n=258
n+2 = 260
n+4=262
n+6=264
n+8=266
Answer: 258,260,262,264,266
Answer:
B is your correct answer.
Step-by-step explanation:
![a^{2} +b^{2} =c^{2} \\a=15\\b=6x-3\\c=24\\\\15^{2} + (6x-3)^{2} =24^{2} \\225+(6x-3)^{2} =576\\(6x-3)^{2} =801\\\\\sqrt{(6x-3} =\sqrt{801}\\\\(6x-3)= 28.301\\6x= 31.301\\x=5.216](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%5C%5Ca%3D15%5C%5Cb%3D6x-3%5C%5Cc%3D24%5C%5C%5C%5C15%5E%7B2%7D%20%2B%20%286x-3%29%5E%7B2%7D%20%3D24%5E%7B2%7D%20%5C%5C225%2B%286x-3%29%5E%7B2%7D%20%3D576%5C%5C%286x-3%29%5E%7B2%7D%20%3D801%5C%5C%5C%5C%5Csqrt%7B%286x-3%7D%20%3D%5Csqrt%7B801%7D%5C%5C%5C%5C%286x-3%29%3D%2028.301%5C%5C6x%3D%2031.301%5C%5Cx%3D5.216)
First we see there are two extremes, two limits
-2 and 5
x is between them
BUT theres a difference , the point at left is black
the point at right is white rounded
this means x is equal or less than -2
and x is ONLY less than 5 , not equal
so this means the answer is the d option
