A) x = 3
b) x = -1
c) x = -9
d) x = 25
e) x = 8
f) x = -29
g) x = -1
h) x = 4/6
The missing angle is 49 :)
Step-by-step explanation:
this is solution for your question
B..
After each million spent, it decreased by 50%.. after 1 million +20% after 2 million +10% .. and so on
3 million is a lot for only 5 percent.. imo
First, you can write that 1260 ÷ 15 = 84.
To prove this one way, you can show the multiplication of the quotient and divisor. If the division was correct, it would end up as the value of the dividend:
84 * 15 = 1260
1260 = 1260
To prove this another way, you can show 84 being added 15 times and seeing if it totals 1260:
84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 + 84 = 1260
1260 = 1260
