Answer:
194
Step-by-step explanation:
t63 = t1 + (n - 1)(d)
= 8 + (63 - 1)(3)
= 8 + (62)(3)
= 8 + 186
= 194
Answer:
<em>(2, - 6, 3)</em><em> </em>
Step-by-step explanation:
2x - y - 3z = 1 ⇒ y = 2x - 3z - 1 .... <em>(1)</em>
4x + 3y + 2z = - 4 .... <em>(2)</em>
- 3x + 2y + 5z = - 3 .... <em>(3)</em>
(1) ---> (2) and (3)
4x + 3(2x - 3z - 1) + 2z = - 4 ⇔ 10x - 7z = - 1 ... <em>(4)</em>
- 3x + 2(2x - 3z - 1) + 5z = - 3 ⇔ x - z = - 1 ⇒ x = z - 1 ---> (4)
10(z - 1) - 7z = - 1 ⇒ <u><em>z = 3</em></u>
<u><em>x = 2</em></u>
2(2) - y - 3(3) = 1 ⇒ <u><em>y = - 6</em></u>
<em>(2, - 6, 3)</em>
First, you need to do the distubutive property, you should get 18m+30=66. Then you could subtract 30 from both sides. Then, you should get 18m = 36. You will then divide both sides by 18. Your answer should be m = 2. Hope this helps!
Distribute the 2 among the terms inside the parentheses. in other words just multiply the 2 with the numbers inside the parentheses.
