It's easy you just need to multiply both numbers by 25
Assuming we're solving for x, all that needs to be done is to add 5 on both sides.
x - 5 >= -2
+5 +5
x >= 3
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:
89.6 square feet
Step-by-step explanation:
The total area is that of a 5×14 rectangle and a circle with a radius of 2.5 feet:
A = bh +πr^2
= (5 ft)(17 f) +π(2.5 ft)^2
= 70 ft^2 + 6.25π ft^2
≈ (70 +19.6) ft^2 = 89.6 ft^2
The approximate area is 89.6 square feet.
Answer:
y=-2x-3
Step-by-step explanation:
subtract 4x from both sides
4x-4x+2y=-6-4x=
2y=-6-4x
divide both sides by 2
-6/2 and -4x/2
simplify
hope this helps
