2. Elle likes to draw while preparing for a math tournament. She spends 90 minutes every day on drawing and math. To help her concentrate better, she draws 30 minutes more than she works on math.
a. Write a system of equations to show the relationship between the number of minutes Elle practices math every day (x) and the number of minutes she drawing every day

Answer 20 centimeters15+8=2323-3=20so the answer is 20 centimeters

The linear equation is: y=ax+b

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to

Ithink the answer may be -7 by when dividing both sides by -3
