1) 50 - 25 = 25 <<< difference and whole.
2) 25 × 100 = 2500
3) 2500 ÷ 25 = 100%
Final Answer: 100% is the percent increased not change
Also have a NICE DAY!!!! :) : D
Answer:
ok C
Step-by-step explanation:
In this problem, the reference of the scale is referring to feet. Firstly, convert 72 inches to feet so that you can properly make the proportion.
72 inches = 6 feet
With the scale of 2 inches per 3 feet, we can set up an easy proportion to see how wide the door will be on the drawing.
3 feet 6 feet
——— = ————
2 inc. ‘x’ inc.
3x=12
X=4 inches
Solving the proportion by cross-multiplication reveals that the scale drawing of the patio door would be 4 inches wide.
Hey there! :)
Answer:
Choice C: x + 8 = 3x.
Step-by-step explanation:
Solve this question by simplifying each answer choice:
a) 4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5. This is incorrect.
b) x/2 = 8
Multiply both sides by 2:
x = 16. This is incorrect.
c) x + 8 = 3x
Subtract x from both sides:
8 = 2x
Divide 2 from both sides:
x = 4. This is correct.
d) x = x+5 /2
Multiply both sides by 2:
2x = x + 5
Subtract x from both sides:
x = 5. This is incorrect.
Therefore, choice C is the correct answer.
-6x <= 4x + 2
Subtract 4x from both sides
-10x <= 2
Divide -10 on both sides
Final Answer: x >= -1/5
