If all 22 tables had 6 people, there would be 132 people seated. There are 13 more than that, so 13 tables have 7 people.
Answer:
3x+13=25
Step-by-step explanation:
Answer:
density =8.87g/cm³
From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.
Step-by-step explanation:
This problem bothers on the density of substances
Given data
Mass m of substance = 239.6grams
length l=3cm
width b=3cm
height h=3cm
Volume of substance =l*b*h
=3*3*3=27cm³
We know that the density of the substance ρ=mass/volume
ρ= 239.6/27= 8.87g/cm³
Slope = (0 - 4)/(-5-5) = -4/-10 = 2/5
y = mx + b
4 = (2/5) (5) + b
4 = 2 +b
b = 2
equation
y = 2/5x + 2
Answer:
m = -1
Step-by-step explanation:
m = (1 - 3) / (4-2)
m = -2/2
m = -1
