Answer:
1: $53750
2: $15975
3: 40
4: 90
5: 51
6a: 20%
6b:204
Step-by-step explanation:
1: to calculate this mulitply 50000*1.075= 53750
2: same deal 15000*1.065=15975
3: We have a ratio of 3:2 and then 60:x because we multiplied the first ratio by 20 to get the 60 in the second we multiply the 2 by 20 as well and get x=40
4: This one is kind of tricky. we know that there are 4 dogs for every 3 cats. We also know that there are 210 animals. This means that 4x+3x=210 solve this and get x=30 you then multiply the ratio 4:3 by 30 and get 120:90
5: 1/5*255=51
5a: 1/5=.2=20%
5b: 255-51=204
Hello!
-4x - 10x
When subtracting terms with the same variable degree (x), we can simply subtract the coefficients from each other:
-4 - 10 = -14
We can add on the x variable once we have done this:
-14x. Therefore, B is the correct answer.
Answer:-1.5 or -3/2
Step-by-step explanation:
Slope formula- (y2-y1)/(x2-x1
-9–3/8-4
-9+3/8-4
-6/4
-1.5 or -3/2
