Answer:
a 10d
Step-by-step explanation:
5d(7-3)- 16d+3*2d
Simplify what is inside the parenthesis first PEMDAS
5d(4) -16d +3*2d
Then we multiply and divide from left to right
5d(4) -16d +3*2d
20d -16d +3*2d
20d -16d+6d
Then we add and subtract from left to right
4d+6d
10d
He sees 3 blue birds if you take 8 - 5 = 3
Answer:
1. 3
2. 20
3. 240
4. 1600
Answer: 1863
Step-by-step explanation:
1.
Slope line=slope red line (since they are parallel)
Equation: y- y point= slope(x- x point)
Equation: y-5= slope(x-3)
Then you substitute the slope and multiply you'll get the answer
2.
Slope line×slope blue line= - 1 (since they are perpendicular) you substitute to find slope
Equation: y-y point= slope(x - xpoint)
Equation: y-0= slope( x+4)
Substitute and multiply to get the answer
Answer:
C. x=18 is the answer
Step-by-step explanation:
