Answer:
780
Step-by-step explanation:
17 is the divisor, while 2635 is the dividend. So that,
= 155
The quotient = 155 = 1 hundreds, 5 tens and 5 units
Also,
2635 - 1700 = 935
Hence, let the unknown value be represented by x. Then;
935 - x
The answer of the subtraction should be equal to the quotient of the division.
935 - x = 155
935 - 155 = x
780 = x
Therefore the unknown value represented by a box is 780.
Part B: It would be 8x+24. You get 4x+12 and double(times 2) it, it would be 8x+24.
Part C: Yes, because the relationship between the ratio would always be proportional.

Answer:
12°
55°
Step-by-step explanation:
∠WXY=90°
∠ZXY=∠WXY- ∠WXZ= 90° - 35°= 55°
- 4x+7°= 55°
- 4x= 48°
- x= 48°/4
- x= 12°
For
ax^2+bx+c
the axis of symmetry is -b/2a
first one
-3/2=3, nope
2nd one
3/2=3? nope
3rd one
-6/2=3? nope
fourth
6/2=3? yes
answer is last one or
