Answer:
10 spiders and 12 ants
Step-by-step explanation:
You need to create two equations
s = # of spiders
a = # of ants
s + a = 22 heads
since each spider and ant has one head
8s + 6a = 152 legs
since every spider has 8 legs and every ant has 6
s + a = 22 can be turned into s = 22 - a
now use substitution
8(22 - a) + 6a = 152
176 - 8a + 6a = 152
176 - 2a = 152
24 = 2a
a = 12
now that you have the number of ants you can solve for the number of spiders
s + a = 22
s + 12 = 22
s = 10
840 ÷ 3 = 280

1. You have the following information:
<span>
- Maria has 8 1/2 quarts of soil.
- Each pot requires 3/4 quart of soil.
</span>
2. Keeping this on mind, you can convert the mixed number 8 1/2 and the fracion 3/4 to decimals, as below:
8 1/2=8.5 quarts
3/4=0.75 quarts
3. Therefore, you have:
1 pot-----0.75 quarts
x-----8.5 quarts
x=(8.5x1)/0.75
x=11 pots
<span>
For how many pots does Maria have enough soil?
</span>
The answer is: 11 pots
Answer:
x = 35
Step-by-step explanation:
Sum of angles of triangle = 180°
- 60 + 60 + 4x - 80 = 180
- 40 + 4x = 180
- 4x = 140
- x = 140/4
- x = 35°
If you mean: x squared -7x +12 then it is (x-3)(x-4) when factored .
