The answer to this question is n = 3
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30.
Factors of 70: 1, 2, 5, 7, 10, 14, 35, 70
factorization of 45 is 5 x 3 x 3, or 5 x 3^2.
Answer:
3. The missing angle is 56°
4. x = 7
Step-by-step explanation:
3.
We know sum of 3 angles in a triangle is 180°.
Looking at the top triangle, we can figure out the third angle. Let third angle be x:
85 + 35 + x = 180
120 + x = 180
x = 180 - 120
x = 60
<u>The angle "x" and the angle that is missing from the "bottom" triangle in the figure, are vertical angles, and hence, are EQUAL.</u>
So the bottom triangle now has 2 angles, 60 and 64 (given). Let the third angle be y(the one with a question mark). So we can write:
60 + 64 + y = 180
124 + y = 180
y = 180 - 124
y= 56
This is the missing angle.
4.
10x - 5 AND 8x + 9 are vertical angles. They ARE EQUAL.
Thus we can write the equation:
(10x-5) = (8x+9)
10x-8x=9+5
2x=14
x=14/2
x=7
So x = 7
Answer:
Step-by-step explanation:
The question is, how many x and y steps do I have to move the P picture to get it in the Q position. The answer is 2 to the left, so -2, and 4 down, so -4.
Solving for s, I get s = 12.
