(going to number these 1-4 starting with the top one)
1. 6:5
2. 1:3
3. 4:3
4. 1:2
Answer:
Step-by-step explanation:
h and p are the number of history and psych textbooks, respectively.
store sold a total of 411 textbooks in a week.
h + p = 411
The number of history textbooks sold was 69 less than the number of psychology textbooks sold.
h = p - 69
Substitution
(p-69) + p = 411
2p = 411+69
p = 240
h = p-69 = 171
171 history books and 250 psych books
Answer:
H=-2
Step-by-step explanation:
First use distributive property to get 12H+6=30
subtract 6 ob both sides to get -12H=24
Then divide by -12 on both sides
Then that gives you H=-2
Answer:
125+680w≥2,500+450w
Step-by-step explanation:
From the information given, you can say that the money that is received as donation should be equal or higher to the money necessary to cover the annual expenses, which would be the following inequality:
125+680w≥2,500+450w
Then, you can solve for w:
680w-450w≥2,500-125
230w≥2,375
w≥2,375/230
w≥10.33
1.d 2 could be d but I’m not sure.
