Answer:
x,y( 27/13 ,43/13)
Step-by-step explanation:
x=5-4y
•1-2x+5y=16
1-2(5-4y)+5y=16
y=27/13
x=5-4y
x=5-4×27/13
x=-43/13
i dont know i wish I could help.

Answer:
1m 54cm
Step-by-step explanation:
10 students at 1m 40cm
15 students at 1m 58cm
13 students at 1m 60cm
Keep in mind that ratio between cm to m is 1cm/0.01m.
So let find the average by converting cm to m first for the 38 students.
10 students: 1m + (40cm)(0.01m/1cm) => 1.4 m
15 students: 1m + 58cm(0.01m/1cm) => 1.58 m
13 students: 1m 60cm(0.01m/1cm) => 1.60 m
so the average is weighted:
(10*1.4 +15*1.58 + 13(1.6))/38
Therefore the average model height is 1.54 m or 1m 54cm
Answer:
2cm by 3cm by 3cm.
Step-by-step explanation:
So, we are given the following data or parameters or information which is going to help us in solving this particular Question or problem;
=> We have a built rectangular prism.
=> The rectangular prism was built by using 18 cubes.
=> Each of the 18 cubes measure 1 cm on each side.
So, the dimensions of Carley's rectangular prism is given below as the multiples of 18 since each of the 18 cubes measure 1 cm on each side.
That's 2 cm × 3 cm × 3cm. Therefore, the length will be 2cm, breadth will be 3cm and height will be 3cm.
