Answer:
It is 7x + 12
Step-by-step explanation:
[tex]5(3x + 2) - 2(4x - 1)[/tex]
open brackets:
[tex] = 15x + 10 - 8x + 2[/tex]
group like terms together:
[tex] = (15x - 8x) + (10 + 2)[/tex]
factorise out x :
[tex] = x(15 - 8) + 12 \\ = 7x + 12[/tex]
what’s is the area pls pls
Answer:
Step-by-step explanation:
Area of the rectangle = length * width
= (9x - 2)(2x + 5)
Use FOIL method
= 9x*(2x) + (9x)*(5) + (-2)*(2x) + (-2)*5
= 18x² + 45x - 4x - 10 {Combine like terms}
= 18x² + 41x - 10

krishna bought a mobile phone for Rs10,000 and sold it at Rs. 12,000. Find his grain or loss %
Answer: The profit percent is 20%
Step-by-step explanation:
CP = Rs 10,000
SP = Rs 12,000
so
Profit% = (12,000-10,000)/10,000 * 100%
= 2,000/10,000 * 100%
= 1/5 * 100%
= 20%
Answer:
2000 gain
Step-by-step explanation:
A rectangular field, 360 m of length and 150 m of width, is divided in smaller square-size plots. The area of each of these plots is the biggest possible. What is the length of the side of a square plot?
Answer:
60
Step-by-step explanation:
Greatest common factor of 360 and 150 is 30
that means one side of square-size plots will be 30 m
our total area is 360x150
area of square-size plot is 30x30
360x150/30x30 = 12x5 = 60

Consider right angle triangle PQR below Which expressions are equivulant to tan R
We know
[tex]\\ \sf\longmapsto tan\theta=\dfrac{Perpendicular}{Base}[/tex]
P is right angle .If R be theta then PQ be perpendicular and PR be Base[tex]\\ \sf\longmapsto tan(<R)=\dfrac{PQ}{PR}[/tex]
The expressions are equivalent to tan R = PQ / PR. Where PQ is perpendicular, and PR is the base.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
The triangle PQR is given,
∠R=90°
As we know that the tangent is the ratio of the perpendicular and base.
Geometry is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
When P is right-angled and R is theta, PQ is perpendicular, and PR is the base if P is right-angled.
tanθ=P/B
tanR=PQ / PR.
Thus, the expressions are equivalent to tan R = PQ / PR. Where PQ is perpendicular, and PR is the base.

Find the constant of proportionality (r) in the equation y=rx
Answer:
r = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given the proportional equation
y = rx ← r is the constant of proportion
Divide both sides by x
[tex]\frac{y}{x}[/tex] = r
Use any ordered pair from the table.
Using (8, 2 ) , then
r = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]
Answer:
1/4
Step-by-step explanation:
Multiplying the input (x) by (1/4) results in the output. This is direct proportion, and the constant of proportionality is (1/4).

Help me get the anwser to this Equation
Answer:
The answer depends on x.value
Step-by-step explanation:
I. It's linear equation
y = mx + b
when y is output, x is input, m is slope and b is addition
So if x = -1
y = -4/3(-1) - 2
= 4/3 - 2
= (4-6)/3
y = -2/3
It will be something like this (-1, -2/3) when -1 is x.value, -2/3 is y.value
You can given x.value be anything like 0, 1, 2, 3 the graph will be like this

Step-by-step explanation:
10) First find the capacity of the swimming pool.
Volume of the swimming pool= length * depth *width
= 15 * 1.5 * 5
= 112.5 cubic meter
1 cubic meter= 1000 liters
112.5 cubic m = 112.5* 1000 = 112,500 liters
Quantity of salt added to every 10 000 liters = 2 Kg
Quantity of salt added to 112,500 liters = [tex]\dfrac{2}{10000}*112500[/tex]
= 22.5 Kg
what is the answer to 15 and 18? pls help it will mean a lot:)
Answer and Step-by-step explanation:
15. [tex]-\frac{27}{20}[/tex] or [tex]-1\frac{7}{20}[/tex]
-1.35 = -135/100 = [tex]-1\frac{35}{100}[/tex] (Mixed number)
Multiply the number by 100, then divide the number by 100 (but keep it in fraction form).
-1.35 x 100 = -135
[tex]-\frac{135}{100}[/tex] = [tex]-\frac{27}{20}[/tex]
(Mixed Fraction = . To check, multiply the 20 by the 1, then add 7, to get -27/20)
18. [tex]\frac{49}{11}[/tex] or [tex]4\frac{5}{11}[/tex]
4.45 = 49/11 = [tex]4\frac{5}{11}[/tex]
4.4545.....
Multiply the number by 100 (because there is 2 numbers being repeated.
445.4545....
Now subtract by the original number.
445.4545....
- 4.4545....
441.00
Write this as an equation:
(100 x fraction) - fraction = 441 (100 x fraction) - fraction = 99 x fraction
99 x fraction = 441 (Divide both sides by 99)
fraction = [tex]\frac{441}{99}[/tex] (which simplifies down to [tex]\frac{49}{11}[/tex])

Find the value of x.
Answer:
Step-by-step explanation:
Those two angles are equal. They are corresponding angles. In two parallel lines crossed by a transversal. 8 angles are produced. 4 have one value and the other 4 are supplementary to the first four.
These 2 are part of the first group of 4.
So 12x - 8 = 104
12x - 8 + 8 = 104 + 8
12x = 112
x = 9 1/3
put the following equation of a line into slope intercept form simplifying all fractions 5x + 2y = -6
Answer:
The general equation of a slope-intercept form is as below;
[tex]y = mx + c[/tex]
m » slope / gradient
c » y - intercept
x » x - intercept
Since our equation is 5x + 2y = -6, make y the subject:
[tex]5x + 2y = - 6 [/tex]
subtract 5x from either sides:
[tex](5x + 2y) - 5x = - 6 - 5x \\ 2y = - 5x - 6[/tex]
apply the division rule of equality:
[tex] \frac{2y}{2} = \frac{ - 5x}{2} - \frac{6}{2} \\ \\ { \boxed{ \boxed{answer : \: y = - \frac{5}{2} x - 3}}}[/tex]
slope » -5/2
y - intetcept » -3

Answer:
Step-by-step explanation:

You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 3.4 feet long, if the remaining piece needs to be 2.35 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth. PLZZZ HELPP!!!!
Let's assume that the original length of the piece of board is L.
Now you cut two pieces that are 3.4 ft long, so the remaining piece of board is:
L - 3.4ft - 3.4ft = L - 6.8ft long.
Now we know that the remaining must be 2.35 times longer than the pieces of 3.4 ft, then we have the equation:
( L - 6.8ft) = 2.35×3.4ft
solving that for L we get:
L = 14.79ft
Rounding to the nearest tenth, we get:
L = 14.8ft
You should buy a piece of board that is 14.8 feet long.

2. What might be a problem with using interval lengths that are too small?
A major problem with interval lengths that are too small is that it masks the shape of the distribution.
The interval length used in a distribution may be described as the size of the class or the class width. The interval length is usually important when drawing histograms and other related graphs for a grouped distribution.
The most significant effect of using a class interval which is too small is that it masks the actual shape of distribution, Hence preventing it from being distinct.
For best practice, it is essential that the class interval is of moderate width, hence enabling us to have a distribution which isn't maksed nor exaggerated.

Hi ;-)
[tex](r+2)(r-3)=0\\\\r+2=0 \ \vee \ r-3=0\\\\\boxed{r=-2} \ \vee \ \boxed{r=3}[/tex]
Answer:
r = -2 , 3
Step-by-step explanation:
(r + 2)(r -3) = 0
r + 2 = 0 ; r - 3 = 0
Subtract 2 from both sides ; add 3 to both sides
r = -2 ; r = 3
r = -2 , 3
