Of means multiply
is means equals
1/2 • x = -.25
Rewritten
.5•x=-.25
Inverse operations to isolate the variable.
x = -.25/.5
x = -.5
1st decimal place=tenth
2nd=hundreth
to round, you look at the place after it
so 13.8924439894 to tenth
look untill hundreth
13.89
if hundreth<u>></u>5, round tenth up
if hundreth place<5 leave tenth as is
13.89
9<u>></u>5
round up
8+1=9
13.9 is to theh tenth
Answer:
Yes, the triangles are similar by SAS
Step-by-step explanation:
Looking at the picture, we see that there are two triangles with side lengths of different sides. We can deduce that the scale factor is 1 2/3, because 8 divided by 4.8 is 1 2/3, and 10 divided by 6 is the same. Now that we have clarified that the triangles share the same scale factor, we notice that the angle is also the same, as mentioned in the picture. This leads us to say that the triangles are similar by the SAS similarity theorem (Side, Angle, Side). I hope this helped and please don't hesitate to reach out with more questions!
Answer:
the answer is Dilations preserve betweenness of points; therefore, the corresponding sides of pentagons G and G′ are proportional.

Answer:
A. 75
Step-by-step explanation:
to get the average mark multiply the result by it's associated weight
93 × 10% = 9.3
82 × 30% = 24.6
72 × 40% = 28.8
60 × 20% = 12
then add these numbers to get his average 74.7 which is closest to 75
