Answer with Step-by-step explanation:
We have to find the mistake in the solution of Jordan in solving the following equation:
−7x + 25 = 48
Step 1: Subtracting by 25 on both sides
−7x + 25 − 25 = 48 − 25
Step 2: On solving, we get
−7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
Step 4:
Hence, Correct option is:
C: Step 3: He should have divided both sides by −7.
Answer:
is plotted close to 3.
is plotted close to 4.
Step-by-step explanation:
The value of is between and which is close to .
1,333 frogs
okay so we know that mass remains conserved no matter where you are.
same here ^^
if the total mass of brass is 200 kg
the total mass of the new frogs formed from it when put together will be the same :)
and if there were n such frogs formed
we have,
total mass = n × mass of each frog
200 = n × 3/ 20
n = 4000/ 3
so it becomes something like 1,333.33
that is nearly 1,333 frogs can be made out of 200 kg of brass each weighing 3/ 20kg (the last ones a bit less to make upto 200kg)
2/5
We can find the slope using two points
(0,0) and (5,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(5-0)
= 2/5
