Answer:
R=(5C/A)-1.5
Step-by-step explanation:
R=5(C/A-0.3)
1) Distribute the <u>5</u> to C/A and -0.3
R=5C/A-1.5
The <u>distributive property</u> says a(b+c) = ab+ac
Let me know if you have any confusion :)
Answer:
see attached diagram
Step-by-step explanation:
First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.
When x=0, then 150y=1500, y=10.
When y=0, then 50x=1500, x=30.
Connect points (0,10) and (30,0) to get needed dashed line.
Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because

This means that origin lies outside the needed region, so you have to choose the semiplane that do not contain origin (see attached diagram).
Answer:
400
Step-by-step explanation:
2,800/12 =233.3333333333 and that would leave 400
8 I believe if not use the app so socratic
Answer:
Sum is 1836.
Step-by-step explanation:
As we know,
average= sum/total numbers
153=sum/12
153*12=sum
sum=1836
