Step-by-step explanation:
1 pint=20T-shirts, find 1 shirt
divide 1/20 of pint for each T-shirt
Base 10 blocks are used to perform arithmetic operations.
To model the product of 3 and 0.51, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>
The expression can be represented as:

Express 0.51 as 0.5 + 0.01

- 0.5 means 5 tenths
- 0.01 means 1 hundredths
- 3 means that, the above blocks are needed in three places.
Hence, Evan needs <em>3 copies of 5 tenths and 1 hundredths.</em>

X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
Thank you for posting your question here at brainly. The two postulate planes is the below:
1: A line contains at least two points. Postulate 1a: A plane contains at least three points not all onone line. Postulate 1b: Space contains at least four points not all on one plane. Postulate
5: If two planes intersect, then their intersection is a line.
