Answer:
x=7
Step-by-step explanation:
6x+11=7x+4
Y= -1.5see if you multiply the top equation by positive 3 and the bottom equation by positive 2 then you get 6x-15y=3 And the bottom would be -6x+4y=-18 so it would be -11y=-17 -17÷11= -1.5
45,120 if its ten.
45,000 if its ten thousand
Answer:
No
Step-by-step explanation:
This is not a right triangle.
The longest side (23) would need to be the hypotenuse, and the two other shorter sides (6 and 21) would be Leg 1 and Leg 2. By using the pythagorean theorem to see if it is a right triangle you take leg 1 and square it and add it to leg 2 squared (6²+21²) then find the square root of that ( which equals about 22. So no because in order for it to be a right triangle 22 would need to be 23.
Number of girls-27
Number of boys-18
60% of 45 is 27 which is the number of girls.So now you have to subtract 27 by the total which will give you 18
