Answer:
-37
Step-by-step explanation:
for the first equation to equal 4 the x must equal -6.
because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.
So now plug -6 into the new problem so now it is
5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!
hope this helps :)
<span>For any angle between 0° and 180°, the supplement of <em>the angle</em> is 180° – <em>the angle.</em></span>
<span><em>=> </em>180-179=1</span>
<span>So the supplement of 179 is 1.</span>
