Answer:
Eraser cost €0,2
Step-by-step explanation:
Cost of ereaser - x
Cost of pencil - x + 1
x + x + 1 = 1,4
2x + 1 = 1,4
2x = 0,4
x = 0,2
I believe this is J with a radius of 6
the formula for circumference is 2(pi)r so i just took the 12(pi) and divided it by 2, which left me with 6(pi), meaning that 6 would be the "r" in the situation
Let x represent the weight of a large box, and y represent the weight of a small box. The problem statement gives rise to two equations in these unknowns:
.. 12x +2y = 253
.. 3x +5y = 133
A graph shows these equations have solution
.. x = 18.5
.. y = 15.5
A large box weighs 18.5 kg.
A small box weighs 15.5 kg.
Answer:
32 m^2
Step-by-step explanation:
Area = 8 x (2 + 6) x 1/2
Area = 8 x 8 x 1/2
Area = 64 x 1/2
Area = 32

Answer:
x+y=30
2x+3y=80
multiplying equation one by -3 and add equation
-3x -3y=-90
2x +3y=80
2(10)+20(3)=80
80=80
