Answer:
3x - 20 = 13
Step-by-step explanation:
1. The word is signals the equal sign.
The difference of three times a number and 20 = 13
2. The word difference signals subtraction.
3. The phrase a number sigals that the number is unknown, so a variable should be used. In this case, I'll use x.
4. Three times that number = 3x.
The difference = subtraction.
3x-20=13
Answer: the number is 11
3 times a number becomes 3x. is becomes an = sign rhen the given amount, 13
3x - 20 =13
3x = 13 + 20
3x =33
x= 11
She shaded area?
12 x 10 = 120
6 x 7 = 42
42 divided by 2 = 21
Now we subtract both areas:
120 - 21 = 99 of the shaded region.
about 7.6 days long
42 divided by 5.52 = about 7.6
good luck!!... hope it help! :)
