Answer:
2. A
3. C
4. B
Step-by-step explanation:
2. To answer # 2, just add all the sides together...
(5x-7) + (3x-4) + (2x-6)
= 10x - 17
3. To answer # 3, divide/mulitply both the numerators and denominators by the same number and check to see if that answer matches the displayed answer...
a) 28 divided by 7 is 4, so divide the whole fraction by 7 to see if the fraction is proportional...
28/7 = 4
49/7 = 7
b) 4 goes into 16 4 times so multiply
by 4...
4 x 4 = 16
7 x 4 = 28
= 
c) 4 goes into 16 4 times so multiply the whole fraction by 4...
4 x 4 = 16
7 x 4 = 28
≠ 
d) 4 goes into 20 5 times to multiply the whole fraction by 5...
4 x 5 = 20
7 x 5 = 35

C is the answer because the fractions are not proportional.
4) 25% is a quarter of 100%. A third of 100% is 75%.
$120 - 0.25($120) = $90
Another expression for the for sale price is...
B) 0.75($120) = $90
Answer:
0.61

11/3 divided by 2/3 is 0.61 and continueing meaning it would go a little bit after a third
Answer:
A. No
B. Yes
C. No
D. Yes
E. Yes
Step-by-step explanation:
3(x + 2) = 3x + 6
A. 3x + 2 is not 3x + 6
B. 3(2 + x) = 6 + 3x is equal to 3x + 6
C. 3x + 2x is not the same as 3x + 6
D. x + 2x + 2 + 4 = 3x + 6 is equal to 3x + 6
E. x + x + x + 1 + 1 + 1 + 1 + 1 + 1 = 3x + 6 is the same as 3x + 6
Um i just started school about three weeks ago and im in advanced but i have not learned that
To determine how many times larger the peach got, you will divide the new diameter by the original diameter length.
188869/98 = 1927.2
The new diameter is approximately 1927 times longer.
To convert this to scientific notation, move the decimal point from the end (on the right) to between the 1 and the 9 to get 1.927.
Then count the number of decimal places you moved to get there, because this represents how many groups of 10 you adjusted your place value by and then becomes your exponent in scientific notation.
1.927 x 10^3 times is the answer in scientific notation.
