Answer:
D
Step-by-step explanation:
the symbol is wrong because of the numberline
Answer:
5y+8(x-3y)=7x-12
5y+8x-24y=7x-12
8x-7x + 5y-24y= -12
X - 19y = - 12
9x+3(x-9y) =11y+46
9x+3x - 27y = 11y + 46
12x -27y - 11y = 46
12x - 38y = 46
Now joining together
X - 19y = - 12
12x - 38y = 46
Multiple by 12 the first equation and Substract after
12x - 228y = -144
12x - 38y = 46
- 190y = -98
Y = 1.9
12x - 38y = 46
12x - 38(1.9) = 46
12x - 73.67 = 46
12x = 46 + 73.67
12x = 119.67
X = 9.97
So the answer are :
X = 9.97
Y = 1.9
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
1.)
Old Number:35
New Number:45
Now, subract the new number(45) from the old number. (35)
45-35 is 10. Now divide the old number (35) by 10.
You'll get 3.5. 3.5%, increase is the answer for #1.
2.) Old: s (students)
New: 36,750
Do 100+5 (Addition because we do not know what the old number is.) 100+5 is 105. Move decimal over twice and you get 1.05. Multiply 36,750 by 1.05.
There were 38,587.5 kids last year.
3.)Since the discount is 15% off, do 100-15=85. Now, move the decimal over from the percent, and that makes that .85. Now multiply 50x.85. You get 42.5, or $42.50. Now the coupon is 10%, So subtract 100-10, giving you 90. Now move the decimal over. .90. Multiply 42.5 (or 42.50) by .90. You get 38.25. You do have enough money.
4.) Subtract 100-15, giving you 85. Move decimal over from percent. .85.
Now you would multiply .85 times k. B should be the answer.
all you need to do is subtract. 133-87 which is 46 so <AKD is 46deg
