Answer:
1. no. 2.no
Step-by-step explanation:
1.
= (5\3) × (1/1-x)
but 8-8x = 8(1-x)
2. 2(6-3x) = 12-6x =6(2-x)
2(3x) + x= 6x +x = 7x

Answer: -12x^2 + 15x
Answer:
Step-by-step explanation:
1 group = 10 students
x group = 240 students.
1/x = 10/240 Cross multiply
10x = 240 Divide by 10
10x/10=240/10 Do the division
x = 24
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)
A = 3.14 x 36
A = 113.1
Hey!
------------------------------------------------
First Equation:
2x + 3 = -7
2x + 3 - 3 = -7 - 3 (Subtract 7 to both sides)
2x = -10
2x/2 = -10/2 (Divide 2 to both sides)
x = -5
------------------------------------------------
Second Equation:
4.5x - 7 = 20
4.5x + (-7) + 7 = 20 + 7 (Add 7 to both sides)
4.5x = 27
4.5x/4.5 = 27/4.5 (Divide 4.5 to both sides)
x = 6
------------------------------------------------
Third Equation:
-3x + 7 = 28
-3x + 7 - 7 = 28 - 7 (Subtract 7 to both sides)
-3x/-3 = 21/-3 (Divide -3 to both sides)
x = -7
------------------------------------------------
Answers:
2x + 3 = -7 → x = -5
4.5x - 7 = 20 → x = 6
-3x + 7 = 28 → x = -7
------------------------------------------------
Hope This Helped! Good Luck!
