Answer:
Solution: x=5
Step-by-step explanation:
Equations
This is an equation in the form of a proportion or ratio:
[tex]\displaystyle \frac{2}{x+3}=\frac{5}{4x}[/tex]
To solve it, we eliminate the denominators by multiplying by both of them.
Multiply by (x+3)(4x):
[tex]\displaystyle (x+3)(4x)\frac{2}{x+3}=(x+3)(4x)\frac{5}{4x}[/tex]
Simplify both sides:
[tex](4x)*2=(x+3)*5[/tex]
Operate:
[tex]8x=5x+15[/tex]
Simplify:
[tex]3x=15[/tex]
Solve for x:
[tex]x=15/3=5[/tex]
Solution: x=5
You deposited $100 in a savings account 3 years ago. The simple interest rate is 2.3%. How
much money is in the account after 3 years?
Answers
Answer:
Final Balance = 106.90$
Step-by-step explanation:
Using the simple interest formula I = prt.
The current balance after accumulated interest is B = I + p.
Given a principle of $100, time of 3 years, and interest rate of 2.3%.
I = (100$)(3y)(2.3%) = (100)(3)(2.3%) = (300)(2.3%) = (300)(0.023) = 6.90$
B (final balance) = 6.90$ + 100$ = 106.90$

· The senior class is planning an end of the year party to celebrate graduation. Their
total budget for food and drinks is $600. Each plate of food costs $5, and each drink
costs $1. Each person at the party gets one plate of food and one drink, with none
leftover. How many people went to the party?
Solve problem using systems of equations.
Answers
Answer:
100
Step-by-step explanation:
Because everyone had one plate and one drink, we can combine those individual prices.
5 + 1 = 6
Now we divide 600, the total cost, by 6, the cost for one person.
600 ÷ 6 = 100
So now we know that 100 people went to the party, as there was nothing left over.

You are trying to find the distance AB between two points on either side of a river. You
measure the following distance:
Answers
Answer:32ft
Step-by-step explanation: I missed this as well, ED and AB are the same and if you don’t read you skip over the fact ED equals 32ft. Since ED and AB equal eachother it would be 32ft
The value of AB = 32 feet
What is congruency ?Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same.
Given:
EC= 32 ft = BC
DC= 28 ft =AC
<ECD= <BCA
So, In ΔECD and ΔBCA
EC = BC
DC= AC
<ECD= <BCA
Thus, by SAS ΔECD ≅ ΔBCA
Hence, by CPCT : ED= BA = 32 ft.

How are the rules for dividing two negative fractions related to the rules for multiplying
two negative fractions? Will the answer be positive or negative? Explain.
Answers
The relation between multiplying and dividing two negative fractions is needed.
When multiplying and dividing two negative fractions the answer will be always positive.
Let [tex]-\dfrac{a}{b}[/tex] be one fraction
and [tex]-\dfrac{c}{d}[/tex] be another fraction
Let us multiply them
[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]
Let us divide them
[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]
This can also be written as
[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]
Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.
Hence, when multiplying and dividing two negative fractions the answer will be always positive.

Determine the intercepts of the line.
y= -3.6 +12
y-intercept:
X-intercept:
Need to know NOW
Answers
Answer:
y = 12
x = 10/3
Step-by-step explanation:
y = -3.6x + 12
From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.
To find the x-intercept, we need to make y equal 0 to find x. So:
0 = -3.6x + 12
-3.6x = -12
x = 3.33333 --> 3 1/3
x = 10/3
x-intercept: 10/3
y-intercept: 12
Steps:
Finding x
y=-3.6x+12
0= -3.6x+12
3.6x=12
x=10/3
Finding y
y=-3.6x+12
y=-3.6(0)+12
y=12
