Answer:
this y easy use your mind
Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
Answer:
<h2>3/4 = 6/8 = 9/12</h2>
we say: they are equivalent fractions
Step-by-step explanation:
3/4 = (3×2)/(4×2) = 6/8
3/4 = (3×3)/(4×3) = 9/12
Answer:
Below.
Step-by-step explanation:
Ok so, Since its 510 - x = 410. Speeds equals the wind.
SO?
100=2x
x=50
410+50 = 460!
The cost of each order of fried crab claw is $4.5 and cost of each cup of gumbo is $3.5
Step-by-step explanation:
Let,
Cost of each fried crab claw = x
Cost of each gumbo = y
According to given statement;
4x+4y=32 Eqn 1
2x+y = 12.5 Eqn 2
Multiplying Eqn 2 by 2
Subtracting Eqn 3 from Eqn 1
Dividing both sides by 2
Putting y=3.5 in Eqn 2
Dividing both sides by 2
The cost of each order of fried crab claw is $4.5 and cost of each cup of gumbo is $3.5
