Answer:
3398
Step-by-step explanation:
(-34×-96=3264) + (-38×-4=152)
3246+152=3398
When multiplying a negative number by a negative number the answer is always positive
Answer:
(i) x° = 28°
(ii) y° = 104°
(iii) z° = 76°
Step-by-step explanation:
x° is an alternate interior angle where transversal PQ crosses the parallel lines, so it has the same measure as the one marked 28°.
x° = 28°
__
The base angles of isosceles triangle PQR are both z°, so we must have ...
z° +z° +28° = 180° . . . . . . . . . sum of angles in a triangle
z° = (180° -28°)/2 = 152°/2 . . . solve for z
z° = 76°
__
y° and z° are a linear pair, so ...
y° = 180° -76°
y° = 104°
Answer:
2:1
Step-by-step explanation:
w:x = 4:6
y:x = 1:3
if w = 4 and x = 6, y = 1/3x = 2
If w = 4 and y = 2, then the ratio is;
w:y = 2:1
Hey!
------------------------------------------------
-x = -1
This statement shows that y equals -1. Since it doesn't show a table or word problem then we already know that the constant of proportionality is -1. Or if you just have the expression just divide the number by 1. -x/1 = -1!
------------------------------------------------
Thus, -1 is the constant of proportionality!
