-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
To build a fence is perimeter so 45.5 x 2= 91
155 - 91= 64
Since that is still two sides you divide 64 by 2 and get 32.
Then area is l x w so 32 x 45.5= 1456
Answer:
15 shrimps
Step-by-step explanation:
<em>We already know that a small shrimp taco has </em><u><em>5 shrimps.</em></u>
⇒ 
<em>We also know that a large taco has </em><em>3 times more</em><em> shrimps than a small taco.</em>
⇒ 
<u>Finding the number of shrimps in a large taco:</u>
<em>Now, simply substitute the number of shrimps in a small shrimp taco in the second equation to find the </em><em>number of shrimps in a large taco.</em>
- ⇒

- ⇒

get a common denominator which is 24
3 7/8 = 3 21/24
6 /4 = 6 6 /24
3 21/24 - 6 6 /24
big number minus small number take sign of larger
6 6/24
- 3 21/24
-------------
5 30/24
3 21/24
--------------
2 9/24
2 3/8
the sign of the larger is negative
-2 3/8
