Answer:
C
Step-by-step explanation:
1)Non- zeros (1,2,3,....) are always significant.
2)Captive zeros are significant too( zeros between non- zeros ).
3)Trailing zeros (zeros at the end) aren't significant always unless if there is a decimal point.
Such this question we have decimal point so we count them
Answer:
50
Step-by-step explanation:
180-(x+80) + 180-(2x+20) = 180 -70
180-x-80 + 180-2x-20 = 110
100-x + 160-2x = 110
260 - 3x = 110
-3x = -150
x = <u>50</u>
Answer:
Purplemath
Introduces reflections in the x- and y-axes. ... To see how this works, take a look at the graph of h(x) = x2 + 2x – 3. ... The previous reflection was a reflection in the x-axis. ... f (x – b) shifts the function b units to the right.
Reduce the fraction using 3
13/15+1/8
13/15=1/5
1/5+1/8
8+5/40
fraction response: 13/40
answer in decimal numbers: 0.325
2(6x+20) +2(8x-16)=180
12x+16x+40-32=180
28x+8=180
X=180-8/28=6
I think so my calculation may be wrong )
