Answer:
3=x
Step-by-step explanation:
multiply 5 times 2x and 4 which is 10x-20
then you have -10=10x-20
then add 20 to both aides and you'll have
30=10x then divide by 10 to get x alone
and you have
3=x

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
Y=4-2x 3y-2x=4 solve using substitution
Answer:
x=1 y=2
Step-by-step explanation:
y=4-2x 3y=4+2x
3*(4-2x)=4+2x
12-6x=4+2x
12-4=2x+6x
8x=8
x=1
y=4-2*1
y=2
It says solve for the variable can you explain
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.

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

You are given $400 as a graduation gift. You decide to place the money in a savings account with an annual interest rate of 7.5% for 9 months. Find the amount of interest you will earn
Answer: $22.50
Step-by-step explanation:
The interest will be gotten by using the formula:
= PRT
= Principal × Rate × Time
= 400 × 7.5% × 9/12
= 400 × 0.075 × 0.75
= $22.50
The interest is $22.50

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
