Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Michelle buys a car that costs $15,000 and that she makes a down payment of $5,000 and later pays $3000 in the next payment.
To get the equation that can be used to find the amount she still owes, C, of the car, we will have to deduct the amount that she has paid from the cost of the car. This will be:
C = 15000 - 5000 - 3000
C = 15000 - 8000
Therefore solving the equation further, the amount left to pay will be:
C = 15000 - 8000
C = 7000
The ratio of Ali's to Beth's score is 5:3. Ali
scored 10 more marks than Beth. Clare scored
7 more than Ali. Find the score of all three.
Answer:
Ali 25
Beth 15
Clare 32
Step-by-step explanation:
Here, we want to get the score of the three
let Ali’s score be x
He scored 10
more than Beth; Beth score will be x-10
Let us now work with the ratio
x/x-10 = 5/3
3x = 5(x-10)
3x = 5x - 50
5x-3x = 50
2x = 50
x =
50/2
x = 25
Beth will
score 25-10 = 15
score had 7 more than Ali,
25 + 7 = 32

Ryan bought a brand new car for $18,000. Its value depreciated at a rate of 1.2%.
Write a function to represent the value of the car as a function of time.
A. v(t)=18000(0.012)^t
B.V(t)=18000(1.2)^t
C.v(t)=18000(98.8)^t
D(t)=18000(0.988)^t
Answer:
A(t)= 18000(0.988)^t
Step-by-step explanation:
Given data
Ryan bought a brand new car for $18,000
Its value depreciated at a rate of 1.2%
Let us use the compound expression
A= P(1-r)^t
substitute
A= 18000(1-0.012)^t
A(t)= 18000(0.988)^t
Hence the expression is A(t)= 18000(0.988)^t
A function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t
Exponential functionThe standard exponential equation is in the form y = ab^x
b is the rate which can be growth or decline
If the value of b < 1, it is a depreciationIf the value of b > 1, it is an appreciationIf Ryan bought a brand new car for $18,000 and its value depreciated at a rate of 1.2%, the exponential equation represented by this statement is;t
v(t) = 18000(1-0.0012)^t
v(t) = 18000(0.988)^t
Hence a function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t

the question is "get y by itself" and the equation is 5x + 5y =15
Answer:
y=3-x
Step-by-step explanation:
Answer:
First we get y on one side by itself.
5x+5y=15
We move x over to the other side.
5x-5x+5y=15-5x
Simplify.
5y=15-5x
Now we remove the coefficient from y.
5y/5=(15-5x)/5
Simplify.
y=15/5-5x/5
y=3-x
The answer is y=3-x

A water gauge in a pond measured 2358 in. At the beginning of the week. After five days of rain, the gauge read 3414 in. By how much did the water level rise?
Answer:
1056 inches
Step-by-step explanation:
Given that :
Initial measurement = 2358 in
Guage level after 5 days of rain (final reading) = 3414 in
Change in water level rise :
Final reading - Initial reading
(3414 - 2358) in
= 1056 inches

Answer:
x = 9
Step-by-step explanation:
Since we know that the triangle is a right triangle we also know that the angle would be 90 degrees
However we are only given 56 and 3x+7
Let 3x+7 be u
We know that 56+u=90 so solve for u
u=90-56
u = 34
Now u = 3x + 7 so,
3x + 7 = 34
solve for x,
3x=34-7
3x=27
x=27/3
x=9.
