Answer: X=-7/2
y=-11
Step-by-step explanation:
4x+3=2x-4
4x-2x=-4-3
2x=-7
x=-7/2
y=-7/2*2-4
y=-7-4=-11
2.40
5.40-2.40= 3 (price of 2 sodas)
8.70 - 7.20 = 1.5 (price of 1 soda)
The soda prices match up so a hamburger is 2.40
The circumference of the circle that has a radius of 28 cm is: 175.9 cm..
<h3>What is the
Circumference of a Circle?</h3>
Circumference of a circle = 2 × π × r, where r = radius of the circle.
Given that a circle has:
radius (r) = 28 cm
Therefore:
Circumference of the circle = 2 × π × r
Plug in the value of r
Circumference = 2 × π × 28
= 175.9 cm.

Idk sorry I am not that good at math :)
1. Rational/The sum of two rationals is always rational
2. Irrational/ the sum of a rational and an irrational is always irrational
3. Irrational/The product of a nonzero rational and an irrational is always irrational
4. Rational/The product of two rationals is always rational
Pretty much all the irrational numbers are the ones with radical signs over them and the rational numbers are the fractions and whole numbers. Once you identify the two numbers to be rational or irrational, you can then find your answer within the second part of the answers.
