Answer:
(2x+5)(3x-2)
Step-by-step explanation:
6x²+11x-10
6x²+15x-4x-10
3x(2x+5)-2(2x+5)
(2x+5)(3x-2)
Answer:2.8284.
Step-by-step explanation:
Answer:
x = 324
Step-by-step explanation:
= 27, where x is the unknown number
multiply both sides by 12:
x = 324
(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y
Replace x and z with y in function (1)
780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330
Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520

Kathy can do 520 catalog orders per day
Step-by-step explanation:
0.2x = 20
The step that should be done is to multiply both sides by 5:
5(0.2x) = 5(20)
x = 100.
