Y=1/5x ! :) I hoped this helped ! Privately message me if you need help with anything else !!
A shape with rotational symmetry means it looks the same after a rotation. The image at number 3 is the only one that has rotational symmetry so answer yes for 3 and no for 1 and 2 okay
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
A is a binomial since it has only 2 values
Answer:
4 x + 5 = 2 x + 2 x + 5
Step-by-step explanation:
If we simplify the following equation it will be 4 x + 5 = 4 x + 5. This equation has infinitely many solutions because every value for x we substitute in, it will be the same on both sides, for example
Substitute x = 7 into 4 x + 5 = 4 x + 5
4 × ( 7 ) + 5 = 4 × ( 7 ) + 5
28 + 5 = 28 + 5
33 = 33
Every x value that we substitute in will result in the equation having the same result on both sides
