Answer:
1.6
Step-by-step explanation:
1 and 6/10 = 1.6 as a decimal
Find the unit rate of this scenario. 250/2 = 125 quarts per hour
Now multiply the unit rate by the new amount. 36*125 = 4500
Add the units
4,500 quarts in 36 hours.
Answer:
c+s < 12, 2c+4s >= 30.
Step-by-step explanation:
Known: at least 30 legs, less than 12 heads.
Each animal has one head, so if there are less than 12 heads, then c + s < 12.
Sheep have four legs and chickens have two legs, so if there are at least 30 legs, then # of chicken legs + # of sheep legs >= 30, ----> c(2) + s(4) >= 30, ----> 2c + 4s >= 30.
The graph attached models the problem is you set the x axis as "c" (# of chickens) and y axis as "s" (# of sheep).
Answer:
- D
- B
Step-by-step explanation:
You may find this easier if you distribute the minus sign first.
<h3>1)</h3>
2a^2 -3ab +5b^2 -a^2 +2ab -3b^2
= (2 -1)a^2 +(-3+2)ab +(5 -3)b^2
= a^2 -ab +2b^2 . . . . . matches choice D
__
<h3>2)</h3>
6x -3 -2x +2
= (6 -2)x +(-3 +2)
= 4x -1 . . . . . matches choice B
Answer:
