Answer:
-4
Step-by-step explanation:
So like ur last problem do it in order left to right.
[8x7]+5x(-8)/(-4)
56+[5x(-8)/-4
56+(-40)/-4
16/-4=(-4)
Sorry if i did in wrong order.
10 / 4 is a fraction, and with fractions, you can reduce or increase the numerator and denominator as long as you keep the same ratio. For instance 2/4 is the same as 1/2 because 2 is half of 4 and 1 is half of 2. An easy way to find equivalent fractions is to divide or multiply the top and bottom by the same value. For the example I used, if I multiply 1/2 by 2/2 I get 2/4 which is equivalent. In this case you can either multiply 10/4 by something like 2/2 and get 20/8 or you can divide 10/4 by 2/2 and get 5/2.
Answer:
well the first one is congruent to 120 because it is alternate interior which means its in between the other two lines
the second one is 60 degrees
Step-by-step explanation:
the second one its 60 degrees cause e and d make a line which is a straight line which is 180 degrees now subtracted 180 and 160 and you get 60 so yeah
i hope this helped
