Divide by 1/2 then multiply both 7 and 45
1.
-3x-4>8
-3x>12
x<-4
2.
-y+4y+3(y-5)
3y+3y-15
6y-15
3.
3*45=135
135*1.08625=146.64375
round
$146.64
4. multily exponents
(-4x^6y)^3=(-4)^3(x^6)^3(y)^3=-64x^18y^3
5. 4+2+4=10
2/10time1/9=1/45
Answer: 450
Explanation: if you divide 180 by 2 then it = how many words he can type in one minute Wich is 90 so then you just multiply 90 by 5 and it gets you your answer.
Answer:
E=2.8 m-40
Step-by-step explanation:
We konw that 30°E=25°M and 310°E=125°M
so if we want to write an ecuation that linearly relates E with M, we can use the formula of the line that crosses two points:
Y-y1= (y2-y1)/(x2-x1)*(X-x1)
In thts case:
- y1= E1= 30
- y2= E2=310
- x1= M1= 25
- x2=M2=125
so
E-E1= (E2-E1)/(M2-M1)* (M-M1)
E-30 = (310-30)/(125-25)*(M-25)
E-30 =280/100 *(M-25)
E-30 =2.8 M- 280*25/100
E-30 =2.8 M-70
E= 2.8 M-70+30
E=2.8 M-40
Good luck!
