-10.3 + y = 5.2

First, regroup the terms. / Your problem should look like: y - 10.3 = 5.2
Second, add 10.3 to both sides. / Your problem should look like: y = 5.2 + 10.3
Third, add 5.2 + 10.3 to get 15.5 / Your problem should look like: y = 15.5

Answer: y = 15.5 (D)

The middle angle in a triangle is 4 times the measure of the smallest angle. The smallest angle is the difference of the largest
a_sh-v [17]

Answer:

  • smallest: 18°
  • largest: 90°
  • middle: 72°

Step-by-step explanation:

We can solve this using the relationship between the angles together with the angle sum theorem. Let s represent the measure of the smallest angle. Then the middle angle is 4s, and the largest angle is (4s +s). The angle sum theorem tells us the sum of angles in a triangle is 180°.

  smallest + middle + largest = 180°

  s +(4s) +(4s +s) = 180°

  10s = 180° . . . . . . . . . . . simplify

  s = 18° . . . . . . . . . divide by 10

  4s = 72° . . . . . . find the middle angle

  4s +s = 72° +18° = 90° . . . . . find the largest angle

The smallest, largest, and middle angles are 18°, 90°, and 72°, respectively.

1 5 7

5 7 1

all diagonal elements of A^2 are: 7^2 + 1^2 + 5^2

Matrix:

9   18  27

27 -9  18

18  27 9

all diagonal elements of A^2 are: 9^2 + 27*18 + 18*27   or (-9)^2

Matrix:

8 1 6

6 8 1

1 6 8

all diagonal elements of A^2 are: 8^2 + 6*1 + 1*6
