(0.75 * 3.5a) + (0.75 * -6b) = 2.63a -4.5b
Answer:
Step-by-step explanation:
It represents 7.
48 degrees and the 5x-17 are alternative interior angles meaning they’re equal so you set the equation up as 5x-17=48, you then add the 17 to the 48 clearing it from the left side of the equation and you get 5x=65 you then divide the 65 by 5 and you get 13 which means x=13. To solve for Y you need to realize that Y+48 MUST equal 180 because they are supplementary angles so you solve by subtracting 48 from 180 and you end up with Y=132 DEGREES don’t forget to add you label. Hope that helped.
Answer:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!
