So, let's establish some variables:

P = Peter
M = Malco = P + 42

Now let us establish an equation to find for P:
268 = P + P + 42
268 = 2P + 42
268 - 42 = 2P
226 = 2P
226 / 2 = P
113 = P

Now to find for M:
P + M = 268
113 + M = 268
M = 268 - 113
M = 155

Answer:
Peter = 113 pounds
Malco = 155 pounds

Answer:

Step-by-step explanation:

4b+5=t

First, you must get the variable alone! Substract 5 from both sides!

4b+5=t

-5 -5

The 5 cancels out because 5-5=0

The new equation is 4b=t-5

You must divide by 4 to get the variable alone since your solving for b!

4b=t-5

4 4

b= $\frac{t-5}{4} \\$

This is your answer!

Michaels buys three over a pound of cheese he puts the same amount of cheese and three sandwiches how many cheese how much chees

Tasya [4]

Question is not proper,Proper question is given below;

Nicholas buys 3/8 pound of cheese he put the same amount of cheese and three sandwiches how much cheese does Nicholas put on each sandwich

Answer:

Nichole can put $\frac{1}{8} \ pounds$ of cheese on each of his sandwich.

Step-by-step explanation:

Total Amount of cheese he has = $\frac{3}{8} \ pound$

Number of cheese sandwiches = 3

We need to find Amount of cheese does Nicole put on each of his sandwich.

Solution:

Amount of cheese on each sandwich can be calculated by dividing Total Amount of cheese he has with Number of cheese sandwiches.

framing in equation form we get;

Amount of cheese on each sandwich = $\frac{\frac{3}{8}}{3}} = \frac{1}{8} \ pounds$

Hence Nichole can put $\frac{1}{8} \ pounds$ of cheese on each of his sandwich.

Rufina [12.5K]

Answer:

Step-by-step explanation:

Area of a triangle is l x w (length x width)

That's 4 cm x 12 cm. Now you could go ahead and figure it out from there, but you have to remember it wants the answer in meters. It tells us that for every 4cm, it is 5m. The easiest way to figure this out is to convert to meters before multiplying. Since 4 cm is 5m, the l becomes 5m. 4 goes into 12 three times. So we would do 5 x 3 to get 15m for the new w. Now we can solve for area.

l x w = A

5m x 15m = A

75m = A

I hope this helped :)
