Answer:
x = all real numbers
Step-by-step explanation:
3(3x+2)-2x=7x+6
Distributive property: 3(3x+2) = 9x + 6
9x + 6 - 2x = 7x + 6
Combine like terms: 9x - 2x = 7x
7x + 6 = 7x + 6
Since the two sides are completely the same, x = all real numbers (no matter what value you put in for x it will always be true)
Answer:
R
Step-by-step explanation:
9x+6-2x=7x+6
9x-2x=7x
7x=7x

What are the values of a and b, and what is an equation for the line?
Answer:
a = 1, b = 6
Step-by-step explanation:
slope of line = (5-2) / (12-3) = 3/9 = 1/3
(3-2) / (b-3) = 1/3
b-3 = 3 b = 6
(2-a) / (3-0) = 1/3
2-a = 1 a = 1
A vendor bought 80 pineapples ₱18.50 each. Three pineapples got rotten, but then he sold the rest at ₱25.00 each. how much did he gain?
Answer:
₱445
Step-by-step explanation:
₱18.50(x)
x = number of pineapples purchased
₱18.50(80) = ₱1480
80 - 3 = 77
₱25.00(z)
z = number of pineapples resold.
25.00(77) = ₱1925
₱1925 = ₱1480 = ₱445
Which values from the set {0, 1/2 , 2.5, 4} make the inequality 8g < 4 true?
Answer:
only 0
Step-by-step explanation:
8g < 4 simplifies to g < 4/8, i.e., g < 1/2
only 0 is smaller than 1/2

Answer:
y=2x−5 is a line
Step-by-step explanation:
Explanation: y=2x−3 is in slope intercept form for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. The y-intercept is the point at which x=0 and y=−3 , which is point (0,−3) You can plot this point on your graph.
-g + 2(3 + g) = -4(g + 1)

the perimeter of a square is 7.2 meters how long is each side ?
Answer:
1.8 meters
Step-by-step explanation:
7.2÷4= 1.8
Answer:
1.8 m
Step-by-step explanation:
let side be 'a'.
perimiter of a square = 4(a)
7.2 = 4(a)
7.2/4 = a
therefore, a = 1.8 m.

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

all of these can be reduced to 1/2.
Why is it important to be careful of the order of the two letters used when naming a ray?
Answer:
Because one letter represents an endpoint and the other doesn't.
Step-by-step explanation:
Ray AB starts at endpoint A and goes through point B and then on, indefinitely.
Ray BA starts at endpoint B and goes through point A and then on, indefinitely.
They 'point' in opposite directions.

y is an irrational number between 3 and 4 . what is the value of y
Answer:
If a and b are two positive rational numbers such that ab is not a perfect square of a rational number, then ab is an irrational number lying between a and b.
So an irrational number between 3 and 4 is=3×4=3×4=3×2=23

Answer:
I believe it is 51.2 I think but yeah
Answer:
-4.75
Step-by-step explanation:
We're trying to find the number that's between -4 and -5. B is on -4.5, so we need to find a number between -4.5 and -5. This would be -4.75. Think of it like quarters, 4 quarters equal a dollar, and B would be the 2nd quarter (which is 50 cents). D would be the 3rd quarter (which is 75 cents). That's where the ".75" comes into the answer "-4.75". Just remember to put NEGATIVE 4.75 and NOT positive 4.75 since this is a negative number.
Hope this helped you!
