Answer: 658
Step-by-step explanation:
If Winslow wants to plant 12 vegetables and has 34 seeds of each kind of vegetable, then she has 12*34 seeds.
12*34=408
If a neighbor giver her 10 more packets, each with 25 seeds, she has 10*25 more seeds.
10*25=250
Then we add 408+250 to get 658 seeds
Answer:
- the y intercept is 1
- the slope of this line is 1
- the equation of the line is y = x + 1
Step-by-step explanation:
First Take two coordinates the line is passing: ( 0 , 1 ) , ( -1 , 0 )
To find slope use: 
: 
: 1
Equation using: y= mx+b ...where m is slope and b is y intercept therefore:
Equation of the line:
y = x + 1
Answer:

Step-by-step explanation:
Let
x ----> the number of lions
y ----> the number f tigers
z ----> the number of zebras
we know that
----> equation A
Remember that


To find out the number of lions, multiply the total animals by the percentage of lions

To find out the number of zebras, multiply the total animals by the percentage of zebras

Substitute the value of x and the value of z in equation A and solve for y
