Answer:
-6
Step-by-step explanation:
1) distribute: 7x+28+6x-18=8x-24-2x+8
2)combine like-terms: 13x+10=6x-32
3)move the variable to one side: 7x+10=-32
4)subtract 10 from both sides: 7x=-42
5) divide each side by 7: x=-6
1-8/9=1/9 of students do not have cell phone,
we can express this fraction as %
1/9*100%=11.11%≈ 11%
Answer:
m∠WZX = 41°
Step-by-step explanation:
diagonals bisect angles and opposite angles are congruent
therefore, ∠WXY ≅ ∠WZY
∠WZY must equal [360 - 2(68)] ÷ 2 which equals 112°
If ∠WXZ = 71° then so does ∠XZY
Which means that ∠WZX must equal 112-71 which is 41°
The point (-4, 7) is in the 2nd quadrant. The coordinate of the preimage
of a -90 degrees rotation that resulted to point (-4, 7) will be in the
third quadrant. (i.e. both x and y is negative). Hence, answer is (-7,
-4).
