If B = -p + 10p2 and C = 2p + 7, find an expression that equals B + 3C in
standard form.
Answer:
10p^2 + 5p + 42 = b+3c
Step-by-step explanation:
b = -p + 10p^2
c = 2p + 7
b + 3c = 5p + 10p^2+ 42

what is the partial product for 1,262 x 3
A 600 and 500
B 15 and 180
C 600 and 900
D 180 and 3000
Step-by-step explanation:
what is THE partial product ? there is a mistake in your problem description.
it must read "what are valid partial products".
1262×3 has the following partial products :
1000×3 = 3000
200×3 = 600
60 × 3 = 180
2×3 = 6
-----------
3786
so, D seems to be the best answer, because both numbers are partial products here.
A, B and C have each only one correct.

Solve this system of equations without graphing and show your reasoning
Answer:
x = 1/5
y = 6
Step-by-step explanation:
System:
{5x + y = 7
{20x + 2 = y
First equation:
5x + y = 7 -> y = -5x + 7
Plug into second equation:
20x + 2 = -5x + 7
Subtract 2 from both sides:
20x = -5x + 5
Add 5x to both sides:
25x = 5
Divde both sides by 25:
x = 5/25 -> 1/5
~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Come back to the first equation:
5x + y = 7
Plus in our x:
5(1/5) + y = 7
Multiply:
1 + y = 7
Subtract 1 from both sides:
y = 6
Hope this helps, have a nice day! :D
