Hello!!! Princess Sakura here ^^
Step-by-step explanation:
First you have to translate the words to numbers into an understandable equation like this...
[tex]2x+3x=3(x+5)[/tex]
Now we can solve for x...
[tex]2x+3x=3(x+5)\\2x+3x=3x+15\\5x=3x+15\\2x=15\\x=7.5[/tex]
So the number is 7.5
5/2 is the number if the sum of twice a number and three times a number is triple the quantity of five more than a number then the number.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The sum of twice a number and three times a number is triple the quantity of five more than a number.
Assuming the number has a unique multiple of x.
∴ 2x + 3x = (3x + 5).
2x = 5.
x = 5/2.

q-10=6(r+1)
rearrange the equation so r is the independent variable
Answer:
r = (q-16)/6
Step-by-step explanation:
q-10 = 6(r+1)
q-10 = 6r+6
q-10-6 = 6r

r = (q-16)/6
Mr. Hawkins is covering a room in carpet. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot of carpets cost $2.10. What is the cost of carpeting the room?
Answer:
$352.80
Step-by-step explanation:
First, we need to find the area of the room.
A = L * W
A = 14 * 12
A = 168 ft²
Now, we need to find the cost.
168 ft² * $2.10 per ft² = $352.80
It will cost $352.80 to carpet the room

Give the name that best describes the parallelogram and find the measures of the numbered angles. The
diagram is not to scale.
Name of the figure:
Measure of angle 1:
Measure of angle 2:
Measure of angle 3:
Measure of angle 4:
Answer:
Step-by-step explanation:
Remark
The way the sides of the figure are marked (they are marked as being equal.), the figure is a rhombus.
<96 and <2 + <1 are supplementary.
<1 = <2 because the diagonal bisects the angle it is connected to
Call <1 = <2 = x
96 + x + x = 180
96 96 Subtract 96 from both sides
2x =84 Divide by 2
2x/2 = 84/2
x = 42
<1 = 42
<2 = 42
Now because opposite angles in a rhombus are equal, the diagonal will make <3 and <4 = <2 + <1
<3 = 42
<4 = 42

Step-by-step explanation:
The functions r and s are defined as follows. r(x)=2x-2 s(x)=-x^2 find the value of s(r(-3)) (please help!)
Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64
Solving EquationsThe equations can be solved when you replace the variable x for a given value or find the zero of functions.
The question gives:
r(x)=2x-2
s(x)=-x²
First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,
r(x)=2*(-3)-2
r(x)=-6-2= -8
Like r(-3)= -8, you should replace x, in s(x), for -8.
s(x)=-(-8)²
s(x)=-64
Hence, s(r(-3)=-64.

A bag of tiles contains 6 green 4 yellow and 5 blue tiles. If one tile is pulled at random what is the probability of not choosing a green tile?
Answer:
3/5
Step-by-step explanation:
6 green 4 yellow and 5 blue tiles = 15 tiles
4 yellow and 5 blue tiles = 9 not green tiles
P( not green) = number of not green tiles / total tiles = 9/15 = 3/5

Answer:
B
Step-by-step explanation:
the awnser is be because that sign in between x and 3 means equal to or less than. so x can be equal to or less than 3. and a closed circle means x can be equal to 3. and the line goes towards the negative because x has to be LESS THAN or equal to 3.

Renata wins a $20 gift card to an online music site. After Renata purchases 16 songs, the gift card has a remaining balance of $0. Which equation represents the relationship between y, the remaining balance on Renata’s gift card, and x, the number of songs purchased?
4x + 5y = –100
5x + 4y = 80
4x + 5y = 16
5x + 4y = 20
Answer:
5x + 4y = 80
Step-by-step explanation:
First, let us look at the given:
x = The number of songs purchased
y = The remaining balance of Renata's gift card
Coordinates:
1. (16,0)
2. (0,20)
Now let's look at the unknown:
Slope =?
Since we have the coordinates we can easily apply the slope formula
Now that we have our slope we can use either point-slope formation or slope-intercept formation, just pick whichever one you're comfortable with.
Point-slope formation
y - y1 = slope (x - x1)
Now just plug in the numbers:
y - 0 = 20/-16 (x - 16)
Now you multiply both sides by -16 to get rid of the fraction
-16(y - 0) = -16 (20/-16) (x - 16)
-16y - 0 = 20 (x - 16)
-16y = 20x - 320
Now subtract 20 from both sides.
-16y - 20x = 20x - 20x - 320
-20x - 16y = -320
Now we need to simplify both sides so we divide both sides by 4
-5x - 4y = -80
Now, remember, one of the rules of standard formation is that the coefficient of x cannot be smaller than zero. So you need to multiply both sides by -1.
-1 (-5x - 4y) = (-80) -1
5x + 4y = 80

-3x+3y=12
Y= x+4
The solution set of this system is best explained by which of these statements?
Answer:
C
Step-by-step explanation:
Reform the first graph: -3x + 3y = 12; 3y = 12 + 3x; y = 4 + x; y = x + 4Compare y = x + 4 and y = x + 4: they are equal, thus the same slope (1) and the same y-intercept (4)
