You would divide 100 by 4 first because according to PEMDAS (If you learned it already), you would have to go from left to right, and multiplication/division comes before addition/subtraction--so you do that math first--and you would get 25. Then you would do the multiplication because, like I said from before, Multiplication/division comes before addition/subtraction, so you then multiply 25 by 3 to get 75. After this, you do the math from the left to the right, and adding -9 to 75 is the same as 75 minus 9, so you would get 66, and that is your answer.
Answer:
27
Step-by-step explanation:
If Fiona's age is x, Dan and Gavyn's ages respectively are x + 8 and x - 9. We can write:
x + x + 8 + x - 9 = 56
3x - 1 = 56
3x = 57
x = 19
The eldest is Dan (because x + 8 > x and x + 8 > x - 9). His age is x + 8 = 19 + 8 = 27.
Answer:I think 57Step-by-step explanation:
Cuz its adding 2 every time then I just did 28 x 2 and added the extra. Does that make sense?
4 x 8 = 28
28 x 2 = 56
56 + 1 = 57
Answer:
(5, -1)
Step-by-step explanation:
You find the center of both the coordinates. For the x axis: 3+7 = 10. 10/5=2. For the y axis: -4+2=-2. -2/2 = -1. Put them together and get the answer! :)
Answer:
I don't know what you're answer is supposed to look like but if you're creating an equation it should be this...
Step-by-step explanation:
( 4 · √x ) - ( 8 · √x )
