Answer:
13÷13=1 so if 13 is lap and 13 is minits then your answer is one.
Step-by-step explanation:
one minute
1) (-4 . x) + (-4 . 3) = 8
-4x - 12 = 8
-4x = 20
x = 20/-4
x = -5
2) 3 = (3/4 . b) + (3/4 . -8)
3 = 3/4b - 6
3 + 6 = 3/4b
9 : 3/4 = b
3 . 4 = b
12 = b
3) (1/6 . p) + (1/6 . 24) = 10
1/6p + 4 = 10
1/6p = 6
p = 36
4) 3/5 . a + 3/5 . 5,25 = 7,35
3/5a + 3,15 = 7,35
3/5a = 4,2
a = 7
Step-by-step explanation:
always remember : the sum of all angles in every triangle is always 180°.
therefore, when we get 2 angles, we can calculate the third. in our case
180 - 71 - 19 = 90
so, the third angle is 90°.
and that makes the triangle a right-angled triangle. or short : right triangle.
so, C is the right answer.
the one to the left is 6x + 2y
the one in the middle is 5x
the one on the right is 3x + y
