Answer:
y= 1.6
You make 2 a decimal by adding .0 at the end (2.0). Then you subtract 0.4 by 2.0 which equals 1.6.
Answer:
scale triangle its side are not equal
11/30 bags of mulch is needed.
<u>Step-by-step explanation:</u>
We have to find the number of bags of mulch.
7 (1/2) sq. yards need 2(3/4) bags of mulch.
So one sq. yd need 2(3/4) / 7(1/2)
We have to change the mixed fraction into improper fraction and then dividing them we will get the answer.
2(3/4) = ((2×4)+ 3)/4 = (8+ 3)/4 = 11/4
7(1/2) = ((7×2)+1)/2 = (14+1)/2 = 15/2
11/4 ÷ 15/2
It change into multiplication as,
11/4 × 2/15 = 11/30 bags of mulch is needed.

Answer:
x =72
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
x+77+31 = 180
Combine like terms
x + 108 = 180
Subtract 108 from each side
x+108-108 = 180-108
x =72
Answer:
C, E
Step-by-step explanation:
The unit rate represented by the point (x, y) is y/x. To find which rates are lower than 3/5, we can find the difference ...
... 3/5 - y/x
If that difference is positive, then the rate represented by the table is lower.
That difference is ...
... (3x -5y)/(5x)
Since we're only interested in the sign, we only need to compute the numerator value.
A. 3·3 -5·4 = -11 . . . . . the table has a higher rate
B. 3·5 -5·4 = -5 . . . . . the table has a higher rate
C. 3·31 -5·18 = 3 . . . . the table has a lower rate
D. 3·18 -5·11 = -1 . . . . the table has a higher rate
E. 3·12 -5·7 = 1 . . . . . the table has a lower rate
Choices C and E are appropriate.
