Dawn has been using two bank accounts to save money for a car. The difference between account 1 and account 2 is $100. If she uses 3/8 of account 1 and 7/8 of account 2, Dawn will have a down payment of $2,000. Solve the system of equations to find the total amount of money Dawn has in each account.
A – B = 100
Three-eighthsA + Seven-eighthsB = 2,000
Dawn has $
in account 1 and $
in account 2.
Answer:
dawn has $ 1,670 in account 1 and $ 1,570 in account 2
Step-by-step explanation:
Answer:
1,670 in account 1 ; 1,570 account 2
Step-by-step explanation:
1x - 1y = 100 X=7 7x-7y= 700
3/8x + 7/8y= 2000 X=8 3x+7y= 16000
10x = 16700

My wife however did bake cookies this year 40% of the cookies she baked chocolate chip if she baked 36 chocolate chip cookies how many total cookies does she bake
Answer:
The total number of cookies is 90
Step-by-step explanation:
As, they said 40% of the total number of cookies is 36, we will take the total as "x"
= 40% of x = 36
40/100 X x = 36
40x = 36 x 100
40x = 3600
x = 3600/40
x = 90
So total cookies she baked = 90
Let's check!
So 40% of 90 need to be 36
So,
40/100 x 90 = 3600/100
= 36
So therefore, total number of cookies = 90

Drag each tile to the correct box.
Each of these equations holds true for one value of x from the set {5, 12, 15, 18). Arrange the equations in increasing order of the x-values that
make them true.
6x - 15 = 75
2(2x - 1) = 46
X + (x - 10) = 26
5x - 3x = 10
Reset
Next
Step-by-step explanation:
6x - 15 = 75, 6x = 90, x = 15.
2(2x - 1) = 46, 2x - 1 = 23, x = 12.
x + (x - 10) = 26, 2x = 36, x = 18.
5x - 3x = 10, 2x = 10, x = 5.
Hence the equations
in increasing order of x-values are:
5x - 3x = 10,
2(2x - 1) = 46,
6x - 15 = 75, and
x + (x - 10) = 26.
Answer:
5x - 3x = 10
2(2x - 1) = 46
6x - 15 = 75
x+(x - 10) = 26
A store is having a sale on office
products. Leo buys 4 notebooks that
have a regular price of $3.30 each. They
are on sale for 20% off the regular
price. How much does Leo pay for the
4 notebooks before sales tax?
A $0.66
B $2.64
C$10.56
D $13.20
Answer:
c. $10.56
Step-by-step explanation:
$3.30 x 4 = $13.20 x 0.20 (20%) = $2.64
$13.20 - $2.64 = $10.56

Marcus states that the polynomial expression 3x3 – 4x2y + y3 + 2 is in standard form. Ariel states that it should be y3 – 4x2y + 3x3 +2. Explain which student is correct and why.
Answer:
They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.
Sample Response: They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree.

A hot air ballon went from an elevation of 6,669 feet to an elevation of 3,402 in 54 minutes. What was its rate of descent?
Answer:
elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

x - 3y = -12
2x + 3y = 3
Answer:
Step-by-step explanation:
to solve this system of equations we will add them
x-3y=-12
2x+3y=3 now +3y-3y=0
3x=-12+3
3x=-9
x=-3
plug in the first equation
-3-3y=-12
-3y=-12+3
-3y=-9
y=3

A motorboat travels 172 km in 3 hours going upstream and 372 in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answer:
The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h
Step-by-step explanation:
System of Equations
Let's call:
B = speed (rate) of the boat in still water
S = speed (rate) of the stream
The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:
[tex]\displaystyle B-S=\frac{172}{3}[/tex]
Multiplying by 3:
3B - 3S = 172 [1]
The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:
[tex]\displaystyle B+S=\frac{372}{4}=93[/tex]
B + S = 93
Solving for B:
B = 93 - S [2]
Substituting in [1]
3(93 - S) - 3S = 172
Operating:
279 - 3S - 3S = 172
279 - 6S = 172
Subtracting 279:
- 6S = 172 - 279
- 6S = -107
Multiplying by -1 and solving for S:
[tex]S = \frac{107}{6}\approx 17.83\ km/h[/tex]
From [2]:
[tex]B = 93 - \frac{107}{6}[/tex]
[tex]B=\frac{451}{6}\approx 75.17\ km/h[/tex]

Peter is folding brochures for his Dad's new company. After 1 hour, he has 330 brochures left to fold. After 4 hours, he only has 90 brochures left to fold.
(From the above statements you should be able to create two ordered pairs. I will create one for you..... (1,330). Now you create the other ordered pair and continue with the problem.)
Write an equation in slope-intercept form, y=mx+b, that represents the number of brochures Peter has left to fold, , after a given number of hours, x.
Answer:
y = -80x + 410
Step-by-step explanation:
(1,330) is the first point, the other point is (4,90)
m = y2 - y1/x2 - x1
m = 90 - 330/4 - 1
m = -240/3
m = -80/1
m = -80
y - y1 = m(x - x1)
y - 330 = -80(x - 1)
y - 330 = -80x + 80
y = -80x + 80 + 330
y = -80x + 410
100) Reflect the point in (a) the x-axis and (b) the y-axis.

The perimeter of a regular decagon is 267m.
State the length of one of its sides??
Answer: 26.7m
Step-by-step explanation:
Since a decagon has 10 sides, you'll have to divide 267m by 10.
267÷10= 26.7
One side of the decagon is 26.7m
(-10,-7) (-8,1) find the distance between the two points show work.
Answer:
8.25
Step-by-step explanation:
(-10,-7) (-8,1) find the distance between the two points show work.
The formula for calculating the distance between the two points is expresses as;
D = √(x2-x1)²+(y2-y1)²
D = √(-8+10)²+(1+7)²
D = √(2)²+8²
D = √4+64
D = √68
D = 8.25
Hence the distance between the two points is 8.25
