Answer:
15
Step-by-step explanation:
The given equation is
When we multiply we obtain the equations:
We add both equations to obtain:
Divide both sides by -7 to get:
No, because the 9 pounds would cost 22.5, and that is 5 cents more than he has
You basically just split it right down the middle. if the cost of something is lets say $75.58, then you would divide 75.58 by 2, which is $37.79
hope it helps!!
m∡A = 70º
1) Considering that the Sum of the interior angles within a triangle is always 180º
2) We can write the following, and solve for x
x+80 + x +80 +40 = 180
2x +160 +40 = 180
2x + 200 = 180
2x =180-200
2x= -20
x=-10
3) So since angle A = x +80, we can plug it into that the value of x
m∡A = x +80º
m∡A=-10+80
m∡A = 70º
The answer is A) x = 6
<span>3(4x-3) - 19 = 8x-4
12 x - 9 - 19 = 8x - 4
12x - 8x = -4 + 9 + 19
4x = 24
4x / 4 = 24 / 4
x = 6</span>
