-5x+7+2x-13<9 Please Explain

olganol [36]

Ok the answer is -5 less than 9 which is true lol

Anyways here’s how I got the answer

-5+7+2x-13 less than 9

Combine like terms in this case it’s -5 and 2, and the other is 7 and -13

-5+2= -3
7-13= -6

Ok now that that’s done here’s the next step

-3x-6 less than 9 solve it

-3x-6 < 9
+6< +6

-3x < 15

Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5

And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)

Answer:

3.5(1.6 + 4.6 - 8.5) - 9.75
= 3.5(-2.3) - 9.75
= -8.05 - 9.75
= -17.8

Step-by-step explanation:

1.6 + 4.6 - 8.5 = -2.3
3.5(-2.3) = 3.5 × -2.3 = -8.05
-8.05 - 9.75 = -17.8

I hope this helps!

zysi [14]

.8 (88%)+.2x=90%
70.4%+.2x=90%

subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
