Answer:
7.5×10^4
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer: t-13 C
Step-by-step explanation:
If the regular price of a tent is 13 and Harold has a coupon for 13 off, this means Harold has been subsidized by a factor of 13. The amount Harold will pay will be 13 less than t which is t-13 i.e 13 subtracted from the total regular price.
Answer:
1. x=70
2. x=70
3. x=60
4. x=40
5. x=10
6. x=6
7. x=12
8. x=9
9. 88
10. 76
Step-by-step explanation:
1. Isosceles triangles have two sides equal to each other. If the unequal side is 40 degrees and there are 180 degrees in a triangle, 180-40=140/2=70 degrees for the other two sides.
2. Same explanation as 1.
3. Equilateral triangles all have the same degrees. If 60 is the degree for one angle, it is the degree for the other two as well.
4. Same explanation as 1.
5. All side length of an equilateral triangle are the same. If the side length of one side is 10, the other two sides are 10 too.
6. Same explanation as 5, but with 6 as the side length.
7. It is an isosceles triangle and two sides are equal. Since one side is 12 and the other side is the second of the equal sides, the side length would be 12
8. Same explanation as 7, but with 9 as the side length.
9. 180-46=134-46(other side length)=88 (remaining side length)
10. 2x+2+2x+2+3x+1=7x+5. 7x+5=180. 180-5=175. 175/7=25. 3(25)+1=76.
Hope this helps!!
N would be 140 because 140 divided by 14 is 10.
