24x - 17 x ≥ 13x +15
Pls solve and add the equation if you can thank you :)
Answers
Given :-
[tex]24x - 17 x ≥ 13x +15[/tex]
Solving it,
[tex](24 - 17)x \geqslant 13x + 15[/tex]
[tex] = > 7x \geqslant 13x + 15[/tex]
[tex] = > 7x - 13x \geqslant 15[/tex]
[tex] = > (7 - 13) x \geqslant 15[/tex]
[tex] = > - 6x \geqslant 15[/tex]
[tex] = > x \leqslant - \frac{15}{6}[/tex]
By reducing to lowest terms, we get,
[tex]x \leqslant - \frac{5}{2}[/tex]
So, Value of x is [tex] - \frac{5}{2}[/tex]
24x + -17x = 13x + -15
Combine like terms: 24x + -17x = 7x
7x = 13x + -15
Reorder the terms:
7x = -15 + 13x
Solving
7x = -15 + 13x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13x' to each side of the equation.
7x + -13x = -15 + 13x + -13x
Combine like terms: 7x + -13x = -6x
-6x = -15 + 13x + -13x
Combine like terms: 13x + -13x = 0
-6x = -15 + 0
-6x = -15
Divide each side by '-6'.
x = 2.5
Simplifying
x = 2.5

Match each rational number with a point on the number line.
(Be sure to use the numbers 1 through 4 to indicate which rational number goes in each answer box)
Answers
Answer:
The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
Step-by-step explanation:
Consider the provided number line.
From the number line we can observed that:
1) A, B, C and D lies between -1 and 0.
2) Point A and B lies between -1 and -0.5
3) Point C and D lies between -0.5 and 0
Therefore, the value of A and B must have a negative value lying between -1 and -0.5
Also, the value of C and D must have a negative value lying between -0.5 and 0.
Now consider the provided options.
Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16
This is Incorrect representation because the value of A and B should lying between -1 and -0.5.
Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.
Also they are in ascending order from -1 to 0.
Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

evaluate 36 / x + 9 when x equals 3
Answers
Answer:
3.Step-by-step explanation:
Given equation:
36 ÷ x + 9Given variables:
x = 3.Solve:
36 ÷ x + 9= 36 ÷ 3 + 9= 36 ÷ 12= 3.Multiply all terms by x and cancel:
36+9x=3x
9x+36=3x
(Simplify both sides of the equation)
9x+36−3x = 3x−3x
(Subtract 3x from both sides)
6x+36 = 0
6x+36−36 = 0−36
(Subtract 36 from both sides)
6x = −36
6x/6 = −36/6
(Divide both sides by 6)
x = −6
Check answers. (Plug them in to make sure they work.)
x = −6

Step-by-step explanation:
Answer:
y-intercept: 3
Slope: -3
Step-by-step explanation:
y-intercept
To find the y-intercept, see what point on the y-axis (vertical bold line on the graph) the line passes through.
Slope
To find slope, find 2 points (from left to right) on the line and and put the height difference over the width difference in a fraction (simplify if possible). At points (0,3) and (1,0) there is a height drop of 3 (so -3) and a width of 1 and [tex]\frac{-3}{1}[/tex] gives you a slope of -3.

A vintage wheel needs to be banded with an iron strip. If the wheel’s radius is 11 inches, how long must the iron strip be to go all the way around the wheel? Complete the steps below to answer the question.
Answers
Answer:
Step-by-step explanation:
first lets find the circumference of the wheel:
[tex]C=\pi *d[/tex]
we have to find the diameter out of the radius:
[tex]d=r*2[/tex]
because the radius is half of the diameter, intrhis case i have to findf the diameter so i do multiply it with 2:
[tex]r=11\\d=??\\d=11*2\\d=22[/tex]
we found the diameter now we are going to find the circumference :
[tex]C=\pi *d\\C=\ 3.14*22\\C= 69.08[/tex]
Another way (easier)to find the circumference is:
[tex]C=2\pi *r\\C=2(3.14)*11\\C=69.08[/tex]
At the end it will hav ethe same answer.
Answer:
69.08 inches
Step-by-step explanation:
substitute the values of r (11 inches) and pi (3.14) in the formula c = 2πr to find c:
c = 2 × 3.14 × 11 inches
c = 69.08 inches.
the circumference of the wheel is about 69.08 inches.

6 8/10 + 5 5/10 + 3 7/10
combine like terms
6+5+3= 14

14+2 = 16
Answer:
550 pieces of candy (total), 150 pieces of candy for Maria, 200 pieces of candy for Lucas, 200 pieces of candy for Mateo.
Step-by-step explanation:
Maria filled
6 + 4 + 5 = 15 boxes of candy.
Lucas filled
3 + 7 + 10 = 20 boxes of candy.
Mateo filled
3 + 7 + 10 = 20 boxes of candy.
x = 10 pieces of candy.
15x = 150 pieces of candy (Maria).
20x = 200 pieces of candy (Lucas).
20x = 200 pieces of candy (Mateo).
150 + 200 + 200 = 550 pieces of candy in total.
