Answer:
Step-by-step explanation:
The coefficients of x and y in the first equation will be the 2 x 2 matrix first row and the coefficients of x and y in the second equation will be the second row:
When you take the inverse of that 2 x 2 matrix and multiply it with the right side matrix (-16 -48), you can find the solution for x and y.
Answer:
Assuming that you're calculating surface area it would be:
16+10+10+10+10 or B
Step-by-step explanation:
Answer:
B.) transitive property of equality
Step-by-step explanation:
x = –3 and –3 = z, then x = z.
Symmetric property of equality: if a = b then b = a
Transitive property of equality: if a = b and b = c, then a = c
Closure property of multiplication: the set is closed under multiplication
Closure property of addition: the set is closed under addition
Answer: 5:3
Step-by-step explanation:
For every 5 tennis balls Ms Omar has, there are 3 tennis rackets. To make a ratio is to make a proportion of tennis balls to racket balls which equals:
5 : 3.
The ratio of tennis balls in the bin to tennis rackets is 5:3.
