Answer:
y = -1/2x + 7/2
Step-by-step explanation:
Answer: 2(x-1) = 2x-2
Step-by-step explanation:
Hello!! Your answer is right :) this is because if you distribute the 2, you get 2x-2 which is the same as on the other side of the equal sign. Good job!!
One number is 15 and the other is 16. You get this answer by first finding a factor of 3(15) that when it's subtracted from 31 gives you a factor of 8(16). Then you divide in this case 15 by 3 and get 5 and 16 by 8 and get 2. The reason you divided the numbers is because now you have 5 which is 1/3 of 15 and 2 which is 1/8 of 16. Now that you have your numbers that equal your fractions multiply 5 which is your 1/3 by the 2 from your 2/3 to get 10 which is 2/3 of 15 and 2 which is 1/8 by the 5 from you 5/8 to get 10 which is 5/8 of 16
A + B = 180
A - B = 70
therefore:
A = B + 70
(B + 70) + B = 180 by substitution
2B = 110
B = 55
A = 180 - 55
B is smallest angle at 55 degrees

Answer:
y = 8
Step-by-step explanation:
It can be useful to write down the values of corresponding parts of the figures. This can help you see the ratio between corresponding measures. Here, we're concerned with sides.
AB = ?, FE= 6
BC = 10, EC = 5 . . . . . a ratio of 2:1
CD = ?, CG = ?
DA = y, GF = 4
So, the proportionality of the sides in these similar figures means ...
y/4 = 10/5
y = 4×10/5
y = 8 . . . . multiply by 4
