One number is 10 more than another. The sum of twice the smaller plus three times the larger, is 55. What are the two numbers?
9514 1404 393
Answer:
5 and 15
Step-by-step explanation:
Let x represent the smaller number. Then the larger is x+10. The sum is ...
2x +3(x+10) = 55
5x +30 = 55
5x = 25
x = 5
The two numbers are 5 and 15.

322 rounded to the greatest place value
Answer:
322 rounded to the greatest place value
320After rounding off 322 to the nearest tenths, the resultant number is 320.
What is rounding off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. Round the number up if 5, 6, 7, 8, or 9 follow the number you are rounding.For instance, 40 when rounded to the nearest ten is 38.
So, 322 rounded to tenth place:
Since in the tenth place, there are 2.Then after rounding off:
322 ⇒ 320Therefore, after rounding off 322 to the nearest tenths, the resultant number is 320.

Find −1/5+17/10. Write your answer as a mixed number in simplest form.
Answer:
1 1/2
Hope I helped
Answer:
1 1/2
Step-by-step explanation:
To add fractions together you have to have a common denominator. To do this, I multiplied -1/5 by 2 to get -2/10 which has the same denominator (10) as 17/10. now you add the numerator of both fractions. -2+17 equals 15. so your new fraction is 15/10. 15 divided by 10 is 1.5 which you can write as 1 and 1/2.

Find the gradient of the line perpendicular to AB
Find the equation of the line perpendicular to AB and passing through point C
Answer:
a) 3
b) y=3(x-2)-2
Step-by-step explanation:
a)
Step 1: Find the gradient/slope of AB
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]=[tex]\frac{-2-2}{7-(-5)} =\frac{-4}{12} =-\frac{1}{3}[/tex]
Step 2: Find the gradient/slope of the line perpendicular to AB
The slope of the line perpendicular to AB is the reciprocal of the slope of the line AB multiplied by -1, so the slope of the line perpendicular to AB is 3.
b)
Step 1: Find the formula for the equation of a line
If you have a point and the slope, you can use the point-slope form, which is y-y1=m(x-x1).
Step 2: Plug in values to the formula
y-(-2)=3(x-2)
Step 3: Simplify
y+2=3(x-2)
y=3(x-2)-2
[tex]$a)$[/tex] The gradient of a line perpendicular to line [tex]$AB$[/tex] is [tex]$3$[/tex].
[tex]$b)$[/tex] The equation of the line perpendicular to line [tex]$AB$[/tex] and passing through point [tex]$C$[/tex] is [tex]y=-\frac{1}{3}x+\frac{13}{3}[/tex].
What is slope of perpendicular lines?
Lines that are perpendicular lines have slopes that are negative reciprocals.
It is given that the points,
[tex]$A=\left( -5,2 \right)$[/tex]
[tex]$B=\left( 7,-2 \right)$[/tex]
[tex]$C=\left( -2,5 \right)$[/tex]
[tex]$a)$[/tex] We will find the gradient of a line perpendicular to line [tex]$AB$[/tex] by using the slope formula.
So,
By the definition, the slope or gradient of a line describes its steepness, incline, or grade.
[tex]$m=\frac{{{y}_{2}}-{{y}_{1}}}{{{x}_{2}}-{{x}_{1}}}$[/tex] which is equal to [tex]$\tan \left( \theta \right)$[/tex].
Where [tex]$m$[/tex] is the slope and [tex]$\theta $[/tex] is the angle of incline.
So,
Slope [tex]$\left( m \right)=\frac{-2-2}{7-\left( -5 \right)}$[/tex]
[tex]m=\frac{-1}{3}[/tex]
So, The slope of the line perpendicular to [tex]AB[/tex] is the reciprocal of the slope of the line [tex]AB[/tex] which is multiplied by [tex]-1[/tex].
so the slope of the line perpendicular to [tex]AB[/tex] is [tex]3[/tex].
[tex]b)[/tex] We will find the equation of the line perpendicular to [tex]AB[/tex] passing through the point [tex]C[/tex] that is [tex](-2,5)[/tex] by using the formula,
[tex]y=mx+b[/tex]
Here,
[tex]y=5[/tex]
[tex]x=-\frac{1}{3}[/tex]
We will find the [tex]y-[/tex] intercept of the line [tex](b)[/tex] first.
So,
[tex]$5=-\frac{1}{3}\left( -2 \right)+b$[/tex]
[tex]$5=\frac{2}{3}+b$[/tex]
Subtract [tex]\frac{2}{3}[/tex] both side.
So,
[tex]$b=\frac{13}{3}$[/tex]
So, the line perpendicular to [tex]AB[/tex] and passing throught the point [tex]C[/tex] is,
[tex]y=-\frac{1}{3}x+\frac{13}{3}[/tex].
Hence,
[tex]$a)$[/tex] The gradient of a line perpendicular to line [tex]$AB$[/tex] is [tex]$3$[/tex].
[tex]$b)$[/tex] The equation of the line perpendicular to line [tex]$AB$[/tex] and passing through point [tex]$C$[/tex] is [tex]y=-\frac{1}{3}x+\frac{13}{3}[/tex].

Refer to the system of linear equations shown below. Which of the following statements gives the best choice for multiplying to solve this system using the elimination method? 3x−6y=4 6x+11y=−2
I NEED IT URGENtLY
Answer: I just took the test and the answer is Student should show that the solution to the system of equations 7x - y = 4 and 2x - 3y = 1 is the same as the solution to the given system of equations.
Step-by-step explanation:
The solution for the given system of linear equations is (32/69, -10/23).
The given system of equations are 3x-6y=4 and 6x+11y=-2.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Here,
3x-6y=4 ---------(I) and 6x+11y=-2 ---------(II)
Multiply equation (I) by 2, we get
6x-12y=8 ---------(III)
Subtract equation (III) from (II), we get
6x+11y-(6x-12y)=-2-8
⇒ 23y=-10
⇒ y=-10/23
Substitute y=-10/23 in (I), we get
3x-6(-10/23)=4
⇒ 3x+60/23=4
⇒ 3x=4-60/23
⇒ x=32/69
So, solution is (32/69, -10/23)
Therefore, the solution for the given system of linear equations is (32/69, -10/23).
