Answer:

A) $T=\frac{-20}{4}$

B) T = -5 °C

Step-by-step explanation:

A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:

$T=\frac{-20}{4}$

B) In order to simplify the expression, simply perform the division.

$T=\frac{-20}{4}\\T=-5^oC$

This means that the temperature has dropped by 5 degrees each week.

Answer:

3.5(1.6 + 4.6 - 8.5) - 9.75
= 3.5(-2.3) - 9.75
= -8.05 - 9.75
= -17.8

Step-by-step explanation:

1.6 + 4.6 - 8.5 = -2.3
3.5(-2.3) = 3.5 × -2.3 = -8.05
-8.05 - 9.75 = -17.8

nekit [7.7K]

Each hour,
x makes b/6 bearings
y makes b/4 bearings
z makes b/3 bearings

Together, each hour, x, y and z together make
b/6+b/4+b/3=b(1/6+1/4+1/3)=b(2/12+3/12+4/12)=b(3/4)=3b/4 bearings.

Time to make b bearings =
b/(3b/4)=4/3 hours = 1 hour 20 minutes.
