Answer: (for 11b) 15/6
Step-by-step explanation:
I added image of how I solved (I’m 99% sure this is right)
Hope this helps :-))
Step-by-step explanation:
1.
4(3x + 2) = 4(2x + 3) + 4x do the multiplying
2.
12x + 8 = 8x + 12 + 4x export like terms to the same side of the equation and add/subtract like terms
3.
12x - 12x = 4
4.
0 = 4 this is not an equation so there's no solution to this one equation
1.
10(x + 4) - 3 = 14x + 1 do the multiplying
2.
10x + 40 - 3 = 14x + 1 export like terms to the same side of the equation and add/subtract like terms
3.
36 = 4x
9 = x there's one solution to this equation
1.
1/2 (10x + 15) - 3/2 = 2x + 6 + 3x do the multiplying
2.
(10x + 15)/2 - 3/2 = 5x + 6 export like terms to the same side of the equation and add/subtract like terms
3.
(10x + 12)/2 = 5x + 6 multiply both sides with 2 so we can get rid of fraction
10x + 12 = 10x + 12
0 = 0 there's infinetly many solutions to this equation meaning whatever number written instead of x there will a solution.
The first term of the sequence is already given to be 3. Use this value to obtain the second term.
a2 = 2(a1)^2 = 2(3)² = 18
Use the value of the second term to get the third term through the equation,
a3 = 2(a2)² = 2(18)² = 648
Thus, the answer to this item is letter B.
Answer:
volume of cuboids having size 4cm 3cm and 3cm is 36cm^3 because the formula to calculate volume of cuboids is length × breathe × height.
other question I didn't understand.
Answer:
z = 110°
Step-by-step explanation:
Angles z and the one marked 70° form an linear pair, hence are supplementary.
z = 180° -70° = 110°
<h3>Angles where chords cross</h3>
The angle made by two chords is half the sum of the arcs intercepted by those chords. Here, that means ...
70° = 1/2(60° +x) ⇒ x = 140° -60° = 80°
The arc w completes the circle of 360°, so we have ...
w +x +79° +60° = 360° ⇒ w = 360° -219° = 141°
Finally, z is the average of w and 79°:
z = (w +79°)/2 = (141° +79°)/2 = 110° . . . as above
