Answer:
A 3/4
Step-by-step explanation:
Set up equation to find the percentage 2/7 equals:
Variable x = percentage
2/7 = x/100
Cross multiply:
2 × 100 = 7 × x
200 = 7x
Divide:
28.57142... = x
About 30% (I rounded to 30% because it is a nice number to use when all other numbers end in 5 or 0)
If Alexa has about 30% saved, she will need to save about 70% more. Find the solution that is closest to 70%.
A is 3/4 which comes out to 75%. So far, this sounds like the best answer. Let's check the others just in case.
B is 1/2, or 50% which isn't as close as A was to 70%.
C is 1 1/4 which means 125% needs to be saved. This would mean Alexa is in debt and hasn't saved any money which is not the case.
D is 1/4, or 25%. The trick here is that she's saved about 30% so 25% is closest, but we are looking for how much <em>more</em><em> </em>she needs to save.
Answer:
$400(0.09) = $36.00
$400 + $36 = $436.00
Step-by-step explanation:
(10 + y)² - y² = 3x + 12
(10 + y)·(10 + y) - y² = 3x + 12
10² + 20y + y² - y² = 3x +12
100 + 20y = 3x + 12
100 - 12 = 3x - 20y
3x - 20y = 88
3x - 20 y - 88 = 0 (I suppose it is that one, simplifyied and in order of the letters, or that it you at the previous step)

Answer:
Square
x = 2
y = 1
Step-by-step explanation:
- All sides of the given quadrilateral are marked with identical signs so all sides are equal.
- Also, each angle is right angle.
- So it is a square.
Measures of all ll sides of a square are equal.
Therefore,
5x - 4 = 3x
5x - 3x = 4
2x = 4
x = 4/2
x = 2
5y + 1 = 2y + 4
5y - 2y = 4 - 1
3y = 3
y = 3/3
y = 1
