Answer:
121.50
Step-by-step explanation:
Let x be the earnings
2x+10 = 253
Subtract 10 from each side
2x+10-10 = 253-10
2x = 243
Divide by 2
2x/2 = 243/2
x = 121.50
I just helped my sister on this problem its kinda scary... :P
If you mean 1/3 and 3/5
Belinda has 135 beads in total.
Find 1/3 of 135.
135 ÷ 3 = 45.
Belinda uses 45 beads to make the bracelet.
Hope I helped :)
The answer is n=28;
1. Subtract 14 from both sides (-n/2 = -14)
2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)
3. Divide by -1 to get n by itself (n = 28)
You could also eliminate step three by multiplying by -2 instead of just 2.
Hope this helps!
