Answer:

15) 37 16) -5x+13=-112, x=25 23) l=38, w=19

Step-by-step explanation:

15) l=5w+2, 2l+2w=88

2(5w+2)+2w=88

12w+4=88

w=7, l=37

16a) -5x+13=-112

16b) x=25

23) l=2w, 2l+2w=114

2l+l=114

l=38, w=19

fredd [130]

Answer:

60 litres

Step-by-step explanation:

To obtain the greatest volume of the tin, we calculate the highest common factor of both 120 and 80

Factors of :

80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

The highest common factor is 60.

Hence, the greatest volume of the tin would be 60 litres

Find the measurement of the segment. QT = 28.5 in., QV = 64.7 in.

statuscvo [17]

The question requires getting the length of TV

Answer:
TV = 36.2 in

Explanation:
We are given that point T lies on line QV. The scenario is shown in the attached image.
This means that:
QV = QT + TV

We have:
QT = 28.5 in
QV = 64.7 in

Substitute with the values to get the length of TV as follows:
QV = QT + TV
64.7 = 28.5 + TV
TV = 64.7 - 28.5
TV = 36.2 in

Hope this helps :)
