Twice the sum of a number and 11 is 34.

What is the number?

Answers

Answer:

Twice the sum of 11.5 and 11 is 34.

Step-by-step explanation:

Twice the sum of a number and 11 is 34.

This implies the equation:

2x+11=34 -> Solve for X.

34-11=23.

23/2=11.5

X=11.5

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, Twice the sum of a number and 11 is 34.

Assuming the number to be 'n', so the statement can be numerically expressed as,

2(n + 11) = 34.

2n + 22 = 34.

2n = 12. n = 6.

Given the slope and y-intercept of the line, write the equation in slope-intercept form.

URGENT WILL GIVE BRAINLIEST!!

Answers

Answer:

[tex]y=3x-5\\y=\frac{5}{6} x\\y=-4x+1[/tex]

Step-by-step explanation:

Slope intercept form:

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

With those already given, you need only plug them in to the formula:

[tex]y=3x-5\\y=\frac{5}{6} x+0\\y=-4x+1[/tex]

Answer:

3: y = 3x - 5   4: y = 5/6x   5: -4x + 1

Step-by-step explanation:

I just use y = mx + b

x and y are the coordinates and m is the slope of the line (you could find the slope of a line by using rise over run or (y2 - y1) over (x2 - x1)) The y-intercept or b is the point where the line hits the y axis.

300 + r = 217

Step-by-step explanation:

300 -> 300

added to r -> +

is the same as -> =

217 -> 217

Put this in one equation and you get:

300 + r = 217

If you need to solve for r (need to isolate r to solve for r):

300 + r = 217

r = 217 / (-300)

r = -0.723333333

You are right 300+r=217

Stan's cookie recipe makes 24 cookies and calls for exactly 384 sprinkles. He is wondering how many sprinkles (p)eft parenthesis, p, right parenthesis he will need to make 60 cookies. He assumes each cookie will have the same number of sprinkles.
How many sprinkles does Stan need to make 60 cookies?

how do -11.5 and -9.5 compare? choose the correct symbol.
a: <
b: >
c: =

Answers

Answer:

-11.5 < -9.5

Step-by-step explanation:

The larger the negative number, the less value. So when you compare -11.5 to -9.5, -9.5 is larger in value.

-9.5 is larger because -9.5 is closer to zero which is the midpoint in the number line. And -11.5 is away from 0 so, -9.5 is bigger

Step-by-step explanation:

The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).

Answer:

Step-by-step explanation:

If we choose to eliminate x, multiply the first equation by -3:  -15x - 6y = 3

and multiply the second by 5:  -15x - 35y = 55

Note that this allows us to eliminate x.  We get:

-6y = 3

-35y = 55

which sum up to -41y = 58.  Thus, y = -58/4.
