Answer:
B
Step-by-step explanation:
The slope is -3/7. Use the point-slope form to write the equation.
(y-8)=-3/7(x-5)
If you have a whole dollar then split it up into quarters. 4 quarters is 1 dollar. so take one quarter (25¢) So decimal from would be .25
faction form would be 1/4. beacuse if you multiple .25 × 4 it would be 1. and multiple
1/4 × 4/1 it would be 4/4 which equal 1
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
