Answer:
392.35
Step-by-step explanation:
35% + 35% is 70 % so 133 +133 is 70 % witch is 269.
next we need to figure out 30 percent and they give us 35 % so. you add to zeros to 30 because percentage is out of 100 and there are 2 zeros in 100. so it look like this
3000 ÷ 133 = 22.56 is 30% of 133
70% + 30% = 100%
269 + 22.56= 291.56 is your answer
A,because I subtract 3 minus 1 equal 2.
Answer:
-x + 6
Step-by-step explanation:
(3x + 2) + (-4x + 4)
Distribute + into the bracket (-4x + 4). When you do so, + sign becomes -
3x + 2 - 4x + 4
Rearrange the expression
3x - 4x + 2 + 4
-x + 6

I think it’s 9.5 because it’s a square so all the sides should be equal and you divide 38 by 4 because it has 4 sides
