Answer:
a 30 b -21
Step-by-step explanation:
a 5x = 5(6)
= 30
b 3y = 3(-7)
= -21
50 / 0.40 = 125
To check your answer, 125 * 0.4 = 50

Answer:
215 cm³
8.6 cm
Step-by-step explanation:
given,
density = 10.2 g/cm³
mass = 2.193 kg = 2193g
a. Volume = mass / density
=2193 / 10.2
= 215 cm³
b. given that base area = 25cm²
volume = base area x thickness
thickness = volume / base area
= 215 / 25
= 8.6 cm
Answer:
(11, 0)
Step-by-step explanation:
to find the y intercept, set y to 0.
60x + 55y = 660
60x + 55 * 0 = 660
60x = 660
60x/60 = 660/60
x = 11
y intercept is (11, 0)
