Answer:
x = 0, y = 2
Step-by-step explanation:
- solve the equation for x
3x + 3(x + 2) = 6
2. Substitute the given value of x into the simplest equation y= x + 2
y = 0 + 2
3. Solve the equation for y
y= 2
4. The possible solution of the system is the ordered pair ( x, y)
( x, y) = ( 0, 2)
Answer:
.40 x = 35 equation
x = 87.5
Step-by-step explanation:
Of means multiply and is means equals
40% * x = 35
Change percent to decimal form
.40 x = 35
Divide each side by .40
.40x/.40 = 35/.40
x = 35/.40
x =87.5
Total children = 6
1) Probability of 4 girls =4/6=0.66
Probability of at least 4 girls >_ 0.66
That is greater or equal to 0.66
2) probability of 5 girls = 5/ total children
=5/6=0.83
Probability of at most 5 girls <_ 0.83
That is less than equal to 0.83
