Answer:
x ≤15
Step-by-step explanation:
2x ≤30
Divide each side by 2
2x/2 ≤30/2
x ≤15
Answer
If only {2y(z-1)} is being divided by two:
9x+9+yz-y
If whole equation is divided by two:
9x+9+2yz-2y over 2
Explanation: In the first instance, you can cancel out the 2 in the numerator and denominator, which leaves you 9(x+1) + {y(z-1)}. You can then simplify to get 9x+9+yz-y
In the second instance, you distribute 9 to what is inside the parentheses, and get 9x+1. You then distribute 2y to what is inside the parentheses within the brackets and get 2yz-2y. You are then left with 9x+9+2yz-2y over 2
Answer:
first you try to calculate how many money she has in rands => 850dollar * (18.53rands/dollar) = 15750.5 rands
With that answer you can calculate how many notes of 200 she has so you divide your founded answer by 200 = 78.7525
If you want to know how many of the others she has, you take the numbers after the point (0.7525) and you multiply it with 200 = 150.5 rands left
So in total she has 78 notes of 200
1 note of 100
1 note of 50
and as last she has 0.5 rands left
Step-by-step explanation:
All central angles of a circle add to 360 deg.
m<1 = 90 since <1 is a right angle.
m<1 + m<2 + m<3 = 360
90 + x - 7 + 2x = 360
3x + 83 = 360
3x = 277
x = 277/3
m<3 = 2x = 277/3 * 2 = 554/3 = 184 2/3
-5/8 * 2/3 = -10/24 which reduces to - 5/12
