Answer:
A) B. 18-6
B) 20÷4
C) 20
Step-by-step explanation:
<u>Part A</u>
The order of operations tells you that the first step is to evaluate any expressions in parentheses. Here, that means you first evaluate (18 -6).
__
<u>Part B</u>
After parentheses have been removed, the next step is to perform multiplication and division. Here, there is only one term involving division, so you divide 20 by 4 as your second step.
__
<u>Part C</u>
After you have done parts A and B, your expression is ...
3 + 12 + 5
The value of this sum is 20.
Answer:
11 and 23

He worked 3 8-hour days.
Let x be the number of 8 hour days. Then 10-x is the number of 6 hour days.
8x + 6(10-x) = 66
Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66
Combining like terms:
2x + 60 = 66
Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6
Divide both sides by 2:
2x/2 = 6/2
x = 3
Step-by-step explanation:
y= x+1 -> (y1)
x²-y = 5 => y = x²-5 -> (y2)
(y2) = (y1) =>
x²-5 = x+1
x²-x-6 = 0
(x-3) (x+2)=0
x1=3 or x2 = -2
y1= 3+1 = 4
y2=-2+1 = -1
the intersects are : (3, 4) and (-2, -1)
so, the point A = (-2, -1) => lies below the x-axis.
and the point B = (3, 4)
the point P :
X = -2 + (4/5 × [3-(-2) ])
= -2 + (4/5 ×5)
= -2 +4 = 2
Y = -1 + (4/5 × [4-(-1) ])
= -1 +(4/5 ×5)
= -1 +4 = 3
so, the coordinates P = (2, 3)
