Answer: -40
Multiply 2 by 4.
8+4•3-30•2
Multiply 4 by 3
8+12-30•2
Multiply-30 by 2
8+12-60
Simplify by adding and subtracting:
Add 8 and 12
20-60
Subtract 60 from 20
-40
Answer:
x ⥶ -3
Step-by-step explanation:
2x - 7 -3x ⥶ 10
-x + 7 ⥶ 10
-x ⥶10 - 7
-x ⥶ 3
Answer:
C and E
Step-by-step explanation:
2^x + 1 = 5
2^x = 4
2^x = 2²
x = 2 , y = 5
(2,5) is the solution which lies in Quadrant 1
Answer:
n = 2/3
Step-by-step explanation:
3n - 22 = -20
Add 22 to both sides
-20 + 22 = 2
3n = 2
Divide both sides by 3
2 / 3 = 2/3
n = 2/3
Let me know if I've done something wrong :)
x + 3x + 5x = 54
Combine like terms
9x = 54
x = 6
Now we know that the base length, x, is equal to 6.
From there, we can find the length of the other values as well.
Second piece: 3x = 18
Third piece: 5x = 30
