Answer:
1500
Step-by-step explanation:
48-50
32-30
50 times 30 = 1500
Answer:
the first sentance is wrong, the second one is right, the third one is right and the last one is wrong
Step-by-step explanation:
We are taking one quarter of the 2/5 of the students who play sports.
one quarter of 2/5 is 2/20 or 1/10.
2x - y = -24
x + 7y = 3
Solve one equation for a variable and plug the resulting value into the second equation.
x + 7y = 3 Subtract 7y from both sides
x = -7y + 3
Now, plug that x-value into the x of the first equation.
2x - y = -24 Plug in the x-value
2(-7y + 3) - y = 24 Use the Distributive Property
-14y + 6 - y = -24 Combine like terms (-14y and -y)
-15y + 6 = -24 Subtract 6 from both sides
-15y = -30 Divide both sides by 15
y = 2
Next, plug the y-value back into the second equation.
x + 7y = 3 Plug in the y-value
x + 7(2) = 3 Multiply
x + 14 = 3 Subtract 14 from both sides
x = -11
y = 2 and x = -11
24. (2x+2)+(2x+2)+(2x+2)=(x+8)+(x+8)+(x+8)+(x+8)
6x+6=4x+32
-6 -6
6x=4x+26
-4x -4x
2x/2=26/2
x=13
