which equation is equivalent to 63-3(2-10x)=150
Answers
Answer:
D: 57 + 30x = 150
Step-by-step explanation:
63-3(2-10x)=150
63 - 6 + 30x = 150
57 + 30x = 150
63-6+30x = 150
*57+30x = 150*
30x = 150 -57
30x = 93
x = 31/10

Answer:
Step-by-step explanation:
THE ANSWER IS 200 , 30, Y=50+0.30X, Y=200+ 0.50X
The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
EXPLANATION
The equation given can be express as
y = 0.25x + 50
y = 0.30x + 40
Since, both equations are functions
Equate the two functions together
0.25x + 50 = 0.30x + 40
Collect the like terms
0.25x - 0.30x = 40 - 50
x(0.25 - 0.30) =-10
x(-0.5) = -10
-0.5x = -10
Divide both sides by -0.5
-0.5x / -0.5 = -10/-0.5
x = 10/0.5
x = 20
When collecting the like terms, we isolate values with the same variables from values with a different variables.
If a positive sign crosses an equality sign it automatically becomes a negative sign and if a negative sign crosses an equality operator it automatically becomes a positive sign.
Hence, The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.

The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x. Equilateral means all sides are equal.
Answers
Answer:
Step-by-step explanation:
3*(4x - 3) = 63 Divide both sides by 3
4x - 3 = 63/3
4x - 3 = 21 Add 3 to both sides
4x = 21 + 3
4x = 24 Divide by 4 on both sides
4x/4 = 24/4
x = 6
Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)
Ann and Betty shared a sum of money in the ratio 2:3. If Ann received $120,what was the amount of money shared?
Answers
Answer:
$420
Step-by-step explanation:
Given data
GIven ratio= 2:3
The total ratio= 2+5= 7
Ann's share= $120
Let us apply the part to all approach
let the total amount be x
so for Ann
2/7= 120/x
cross multiply
2x= 120*7
2x= 840
divide both sides by 2
x= 840/2
x= 420
Hence the amount shared is $420
