Answer:
Step-by-step explanation:
Y = - 3x. Equation 1
x + y = - 4 equation 2
Putting value of y
x + (-3x) = - 4
x - 3x = - 4
-2x = - 4
x = - 4/-2 = 2
Putting value of x in the equation 1
Y = - 3(2)
Y = - 6
So 8w=4c and 2c=3g. divide the first equation by 2 and you get 4w=2c. merge the two equation give you 4w=2c=3g, or 4w=3g. multiply 4 on both sides give you 16w=12g. So 16 widgets equal how 12 goof-ups?
First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
Answer:
The trial provides enough evidence that the probability of obtaining heads is less than 0.50 and that the coin is unfair.

Answer:
x = 5
Step-by-step explanation:
<u>Step 1: Multiply out the brackets</u>
48x - 80 - 40x + 80 = 40 → <em>negative + negative = positive [-10 x -8]</em>
<u>Step 2: Simplify</u>
8x = 40 →<em> collect like terms</em>
<u>Step 3: Solve</u>
x = 
x = 5
