Answer:
18:54
Step-by-step explanation:
We have to simplify these ratios.
If the most simplified form of the ratios are equal, they are equivalent
3:9

24:54

18:54

Same ratio as 3:9, so 18:54 is equivalent to 3:9
36:81

Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative
Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
147 ÷ 15 3/4 = 9.333333333333333333 with a repetition bar over the first 3.
