Solve the system of equations:
4x - 3=-2x + 9
Answer:
x=2
Step-by-step explanation:
Step 1: Add 2x to both sides.
4x−3+2x=−2x+9+2x
6x−3=9
Step 2: Add 3 to both sides.
6x−3+3=9+3
6x=12
Step 3: Divide both sides by 6.
6x = 12

Q11) The age of a man is equal to the sum of the ages of his son and daughter. The ratio of the age of the son to that of the
daughter is 5 : 4. If the age of the man is 45 years, find the ages of his son and daughter.
Step-by-step explanation:
Let the ages of son and daughter be 5x and 4x Then
By the question
The age of a man is equal to the sum of the ages of his son and daughter . So
5x + 4x = 9x
Now
it is given that
age of the man = 45
or 9x = 45
x = 45 / 9
x = 5
Finally
Age of son = 5x = 5 * 5 = 25
Age of daughter = 4x = 4 * 5 = 20

A motor bike was originally listed at

price?

Answer:
Single Equivalent Discount % on final price = 41.58%
Explanation:
The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100
and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.
but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:
((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.

Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a radius of 7 inches.
Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?
Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear?
Show all work.
Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

Step-by-step explanation:
for smaller gear circumference=2π×2=4π inches
for larger gear
l=4π
θ=l/r
θ=(4 ×180)/7=720/7=102 .9°
for larger gear circumference=2π×7=14π
number of rotations=(14π)/4π=7/2=3.5 rotations or 3 1/2 rotations.

circumference of circle is. 2π r
2π r = 24
2 * 22/7 * r = 24
r= 24 *7/2*22
r = 3.81
hope it helps
Answer: 3.8
Step-by-step explanation:
The formula for the circumference of a circle is dπ.
Because you want to find the radius you would have to divide the circumference by π.
24/π=7.639437268 this is the diameter.
To find the radius then you have to half it.
Half of 7.639437268 is 3.8 (1 decimal place).

The Dial and the Lewis families when to Taco Box for dinner. The Dials bought 3
burrito meals and 4 taco meals for $48. The Lewis' bought 6 burrito meals and 2
taco meals for $60. How much does a burrito meal cost? How much does a taco
meal cost?
Answer:
A burrito costs $8, while a taco costs $6.
Step-by-step explanation:
Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:
3B + 4T = 48
3B = 48 - 4T
6B + 2T = 60
6B = 60 - 2T
3B = 30 - 1T
30 - 1T = 48 - 4T
30 = 48 - 4T + 1T
30 - 48 = -3T
-18 = -3T
-6 = -T
6 = T
3B + 4x6 = 48
3B + 24 = 48
3B = 24
B = 24/8
B = 8
6x8 + 2x6 = 60
48 + 12 = 60
60 = 60
Thus, a burrito costs $ 8, while a taco costs $ 6.

O
49°
49°
Answer:
∡1 = 82°
Step-by-step explanation:
The sum of the angles of a triangle is 180°.
You could find the missing angle by the following steps:
49° + 49° + x = 180°
x is the missing angle ∡1. Simplify the like terms.
98° + x = 180°
Bring 98° to the other side: makes it -98. This is done to find the value of x.
x = 180° - 98°
x = 82°
Find the inverse function in slope-intercept form (mx+b):
f(x) = - 3x + 9
13 points
Answer:
y= 3- x/3
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=9−3x so it becomes x=9−3y.
Now, solve the equation x=9−3y for y. You would just need to leave y alone so you divide by 3 on both sides (NOT negative 3. Just 3.)
Answer:
y=(-x/3)+3
Step-by-step explanation:
y=-3x+9
x=-3y+9
x-9=-3y, next division
(x-9)/-3=y

y=(-x/3)+3

The total cost of a tablet device comprises the cost of material, labour and overheads in the ratio 3:4:1. The cost of material is $315. What is the total cost of the tablet?
Answer:
$840
Step-by-step explanation:
Given data
The cost of material is $315
The ratio is
3:4:1
The total number of part is
3+4+1= 8
Let us apply the part to all method
let the total cost be x
hence
3/8=315/x
cross multiply
3x= 8*315
3x= 2520
divide both sides by 3
x= 2520/3
x= $840
Hence the total money is $840
