For the first one you have to simplify it because you cannot add a number without a variable to none with one: -36 + 2y
For the second you use P.E.M.D.A.S
parenthesis, exponents, multiply, add, subtract: and you get: 9
3 1/2 - 1 3/4 you get 1 3/4
for the fourth u convert the whole problem into a fraction, and make the 6 and the 7 common denominators, which is 42: you get 7 12/42 (divided by) 2 35/42
Then you take the 7 and the two and add it into the equation by changing them to 42/42 and you get 306/42 (divided by) 87/42, which i have forgotten how to do, because i haven't done this since 6th grade,
For the 1st one you may desire to simplify it because of the fact you will now no longer upload a sort without variable to none with one: -36 + 2y For the 2d you make the main of P.E.M.D.A.S parenthesis, exponents, multiply, upload, subtract: and you get: 9 3 a million/2 - a million 3/4 you get a million 3/4 for the fourth u convert the full subject top right into a fragment, and make the 6 and the 7 consumer-friendly denominators, it particularly is 40 2: you get 7 12/40 2 (divided by utilising skill of) 2 35/40 2 then you definitely particularly take the 7 and the two and upload it into the equation by utilising skill of adjusting them to 40 2/40 2 and you get 306/40 2 (divided by utilising skill of) 87/40 2, which I particularly have forgotten the thank you to do, by way of reality i've got no longer finished this because of the fact 6th grade,

Write your question clearly first before asking people. You lazy piece of sh1t

1)-36 + 8/4y
2)9
3)7/2-7/4
=14-7/4
=7/4
=1 3/4
4)51/7 ÷ 17/6
=18/7
=2.57
