Answer:
I think 140
Step-by-step explanation:
180=x+30+10
x=180-40
x=140
Answer: 7x-5x(exponent of 2)-21
Step-by-step explanation:
Answer:
StartFraction 7 over 8 EndFraction x = 224; x = 256 pounds
Step-by-step explanation:
Given:
Weight Jasper can bench press = 224 pounds.
We need to find the equation and value of x.
Solution:
Let the weight Balin can able to bench press be 'x'.
Now Given:
Weight Jasper can bench press is equal to of the weight that Balin was able to bench press.
framing in equation form we get;
Hence Balin can bench press 256 pounds.
Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5
