Four times the sum of a number and 15 is at least 120. Let x represent the numbe,

4(x + 15) >= 120

4x + 60 >= 120

4x >= 60

x >= 15

x is equal or greater than 15.

4(x + 15) >= 120

4x + 60 >= 120

4x >= 60

x >= 15

x is equal or greater than 15.

5 1/3 + (-3 9/18)

= 5 1/3 - 3 9/18

= 5 1/3 - 3 1/2

= 16/3 - 7/2

= 32/6 - 21/6

= 11/6 or 1 5/6

= 5 1/3 - 3 9/18

= 5 1/3 - 3 1/2

= 16/3 - 7/2

= 32/6 - 21/6

= 11/6 or 1 5/6

solve 12 + 0.35x = 20.05 **Weegy:** Simplifying
12 + 0.35x = 20.05
Solving
12 + 0.35x = 20.05
Solving for variable 'x'.
Move all terms containing x to the left, [ all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 0.35x = 20.05 + -12
Combine like terms: 12 + -12 = 0
0 + 0.35x = 20.05 + -12
0.35x = 20.05 + -12
Combine like terms: 20.05 + -12 = 8.05
0.35x = 8.05
Divide each side by '0.35'.
x = 23
Simplifying
x = 23 ] **User:** solve -6p - 21 = 3p - 12 **Weegy:** B. 3 **User:** solve 78 = -2(m + 3) + m **Weegy:** m = -84. **User:** solve 6 = 2(x + 8) - 5x **Weegy:** 5x - 3 = 12; 5x = 12 + 3; 5x = 15; x = 15/5; x = 3 **User:** solve 6 = 2(x + 8) - 5x **Weegy:** 5x - 3 = 12; 5x = 12 + 3; 5x = 15; x = 15/5; x = 3 **User:** solve 2(x + 4) = 30 **User:** solve 6.7 is greater than or equal to -0.2x + 4.5 **Weegy:** 6.7>-0.2x+4.5

Since x is on the right-hand side of the equation, [ switch the sides so it is on the left-hand side of the equation.

-6p - 21 = 3p - 12

-6p - 3p = -12 + 21

-9p = 9

p = -1

-6p - 3p = -12 + 21

-9p = 9

p = -1
