Get x all alone on its own side:
x=16+5
x=21
Answer:
an = a(n-1) - 7
Step-by-step explanation:
the second term is smaller than the first term 7.
a20 = a19 - 7
a19 = a18 - 7
=> a20 = (a18 - 7) - 7
Then you can accumalate until a1
-> a20 = a1 - 19*7 = 86 - 19*7 = -47
<h2>3w + 6 (w - 4) = 156</h2><h2 /><h2>3w + 6w - 24 = 156</h2><h2 /><h2>9w - 24 = 156</h2><h2 /><h2>9w = 180</h2><h2>÷9 ÷9 ← divide by 9 on both sides</h2><h2 /><h2> w = 20</h2>
1- slope is 4 y intercept 0,2
2- slope is 6 y intercept 0,5
3- slope is 2 y intercept is 0,5
4 -slope is 1 y intercept is 0, 3/4
5- slope is 10 y intercept is 0,3
6- slope is 4 y intercept is 0,1/2
7- slope is 4 y intercept is 0, 3/2
8- slope is 1 y intercept is 0,2
It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
