Answer:
19
Step-by-step explanation:
To solve, you make a systems of equation:
x+(x+3)=25, the x representing the number of pigs. Since there is no multiplication and following the order of operations, you add the x’s to get 2x+3=25. Then, you subtract 3 from both sides to get 2x=22, then divide by 2 on both sides to isolate the variable. Therefore, x=11 and Mary is taking care of 11 pigs.
Answer:
The proportion <u>1 L : 0.26 gal = x L : 12500 gal</u>.
Step-by-step explanation:
Given:
A fountain holds 12,500 gallons of water.
1 L = 0.26 gal
Now, to get the proportion to solve for the number of litres.
<em>On solving :</em>
Therefore, the proportion <u>1 L : 0.26 gal = x L : 12500 gal</u>.
Answer:
yeah that's a true statement
Answer:
Step-by-step explanation:
Use the quadratic formula to find the roots of x²+8x+15
x = [-8±√(8²-4·1·15)]/[2·1] = [-8±√4]/2 = -3, -5
make factors from the roots
x²+8x+5 = (x+3)(x+5)
