You have to find the square root of 169, then add the square root of 169 by 7
Hope this helped :)
Well, since it is asking for an average, we have to add
78+89+87+96=
350... then we divide by 4
which would be 87.5 which IS greater than 80 :)
and less than 90 :)
Answer:
X = 4
Step-by-step explanation:
x2 + 1 = 9
We have to cross 1 over to the other side so that x becomes a value on its own. Because we are it over, the addition sign changes to subtraction which makes the expression,
x2 = 9- 1
x2 = 8
For x to stand alone we have to divide both sides by 2
x 2/2 = x
and 8/2 = 4
Therefore x=4 (Answer)
Answer:
x=4
Step-by-step explanation:
1 Add 11 to both sides.
2x=7+12x=7+1
2 Simplify 7+17+1 to 88.
2x=82x=8
3 Divide both sides by 22.
x=\frac{8}{2}x=
2
8
4 Simplify \frac{8}{2}
2
8
to 44.
x=4x=4
cheek:
1 Let x=4x=4.
2\times 4-1=72×4−1=7
2 Simplify 2\times 42×4 to 88.
8-1=78−1=7
3 Simplify 8-18−1 to 77.
7=7 7=7
(or -3)
