20/4 means 5 * 4 = 20
2725/5 means 545*5 = 2725
0/5 = 0
==============
25x = 1475
x = 1475/25
x = 59 <== 59 boxes of diapers were bought
==============
18h + 70(36) = 4608
18h + 2520 = 4608
18h = 4608 - 2520
18h = 2088
h = 2088/18
h = 116....she did 116 haircuts
=================
575 + 13(118) = total cost Inverse operations to check...
575 + 1534 = total cost 2109 - 1534 = 575
2109 = total cost 575 = 575 (correct)
=================
320/39 = 2240/x....320 miles to $ 39 = 2240 miles to $ x
cross multiply
(320)(x) = (39)(2240)
320x = 87360
87360/320 = x
273 = x....it would cost $ 273
inverse operations to check....320 * 273 = 87360
87360 = 87360 (correct)

Answer:
x = 11
Step-by-step explanation:
ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.
Angles in an equilateral triangle are all 60°.
Thus, ∠L = 60°.
=> 3x + 27 = 60
=> 3x = 33
=> x = 11
Answer:
y = -4x - 22
Step-by-step explanation:
m = -4
using (-6,2)
Slope-intercept: y = mx + b
2 = -4(-6) + b
2 = 24 + b
b = -22
y = -4x - 22
Answer:
Find the minimum or maximum value of the function g (I) = -3x^2 - 6x + 5. Describe the domain and range of the function, and where the function is increasing and decreasing. > -1 all real numbers The function The maximum value is I < 0 The domain is and the range is right of I left -1 is increasing to the of I= and decreasing to the 0 12 :: yo y0 :: 8 :: IS-1 :: -1 :: 0 :: I> 0 :: 1 :: 8 :: < 0 :: left :: all real numbers :: y -8 :: y < 8 :: y8
