A store has a total of 15 bicycles and tricycles. There are 37 wheels. How many tricycles does the store have?
Vlad1618 [11]
X+y=15
2x+3y=37

15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8

x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7

There are 7 tricycles.

Which number line represents the solution set for the inequality 2x – 6 ≥ 6(x – 2) + 8? A number line from negative 1.5 to 1.5 i
Nuetrik [128]

Answer:

A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.

The number line in Option C.

Step-by-step explanation:

We are given an inequality.

2x - 6 \geq 6(x - 2) + 8

We have to find the number line that shows the solution for the given inequality.

If we solve the given inequality,

2x - 6 \geq 6(x - 2) + 8\\\Rightarrow 2x - 6 \geq 6x - 12 + 8\\ \Rightarrow 2x - 6 \geq 6x - 4\\\Rightarrow 2x - 6x \ geq -4 + 6\\\Rightarrow -4x \geq 2\\\Rightarrow -x \geq 0.5\\\Rightarrow x \leq -0.5

is the required solution of the given inequality.

Thus, if we want to plot or show this solution on a number line, then we need to we need to mark the point -0.5 and all the numbers less than -0.5

A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.

This s represented in Option C.
