<u>Given</u>:
Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.
The money that he has saved so far is 30% of the cost of the bike.
We need to determine the total cost of the bike.
<u>Total cost of the bike:</u>
Let x denote the total cost of the bike.
The total cost of the bike is given by
The value of 30% can be written as 
Thus, we get;
Multiplying both sides by 
, we have;
Simplifying, we have;
Thus, the value of x is 500.
Hence, the total cost of the bike is $500.
Answer:
4
Step-by-step explanation:
Step 1:
- 3x + 20 = 8 Equation
Step 2:
- 3x = 8 - 20 Subtract 20 on both sides
Step 3:
- 3x = - 12 Subtract
Step 4:
x = - 12 ÷ - 3 Divide
Answer:
x = 4

Answer:
25.85
Step-by-step explanation:
The area of a circle is given by A = π * r²
We have the value of the area, so we clear r:
r² = A / π
r² = 2100 / π = 668.45
r = √668.45 = 25.85
Step-by-step explanation:
1) -7 (divide -28 by 4 to isolate x)
2) -8 (two negatives = a positive, so it's x + 6 = -2, then subtract 6 from both sides)
3) 5 (subtract 4 from both sides, and multiply each side by -1)
4) 2 (subtract 7 from both sides, then divide by -3)
5) -3 (add 11 to both sides then divide by 25)
it would right to left , my teacher had a little saying , Left is Less
