Answer:
3x+18
Step-by-step explanation:
since 3 is outside the bracket you need to multiply 3 by both x and 6. so 3 multiply x is 3x and 3 multiply 6 is 18, hence 3x+18
To find a percentage increase of 15%, you can multiply the original value by 1.15.
To find a percentage increase of 20%, you can multiply the original value by 1.2.
117.7 * 1.15 = 135.355
So if she orders 15% extra tile, she will order around about 135.355 square feet.
117.2 * 1.2 = 141.24
And if she orders 20% extra tile, she will order around about 141.24 square feet.
Any number between those two values will be the amount of tile she might order.
190 acres of soybeans and 110 acres of corn= 300 acres
corn + soybeans =300
corn +110=soybeans
300-110= 190
He is correct about the dollar bills, but you can split 7.40$ equally
