3x + 5 = x - 10
Solve for x by isolating the variable.
Subtract 5 from both sides:
3x + 5 - 5 = x - 10 - 5
3x = x - 15
Subtract x from both sides:
3x - x = x - x - 15
2x = -15
Divide both sides by 2:
2x /2 = -15 / 2
x = -15/2.
Answer:
-15/12
Step-by-step explanation:
move the variables 3x-x+5=-10 and collect like terms 3x-5=-10-5 and divide both sides 2x=-15
x=-15/12

Find x in the equation: 2x + 9 = 5x - 12
Answer:
x = 7
Step-by-step explanation:
Add 12 to both sides:
2x + 9 = 5x - 12
2x + 21 = 5x
Subtract 2x from both sides:
21 = 3x
Divide each side by 3:
7 = x
So, x = 7

The solution of the inequality is x≥-13 and the graph c represents the inequality, option c is correct.
The given inequality is -1/4(12x+8)≤-2x+11.
Let us solve for x:
Apply distributive property:
-3x-2≤-2x+11
Add 2 on both sides of the inequality:
-3x+2x≤11+2
Combine the like terms:
-x≤13
x≥-13
Hence, the graph of c represents the solution of the inequality.

Plz fasttttttttttttt
Answer:
That would be 6x+35.
Step-by-step explanation:
Given that you do not provide a way to determine the value of x, we cannot simply 6x, but we can simplify 21+14 by solving it and getting 35, resulting in the expression 6x+35.

Xander writes math textbooks that sell x dollars each. he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale. express the total amount of income xander earns from selling y books algebraically
The total amount of income Xander earns from selling y books algebraically is C = 25000 + xy + 0.08y.
What is an equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenarios.
In this situation, Xander writes math textbooks that sell x dollars each, he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale.
c = total amount
y = number of books.
The total amount of income will be:
= 25000 + (x × y) + (8% × y)
= 25000 + xy + (0.08 × y)
C = 25000 + xy + 0.08y

It is a right triangle. The distance is the hypotenuse of the triangle.
Use the Pythagorean theorem:
Distance = sqrt(3^2 + 2^2)
Distance = sqrt( 9 + 4)
Distance = sqrt(13) (exact distance)
As a decimal sqrt(13) = 3.60555

What is the measure of arc S T?
56°
68°
112°
163° (it is 56!)
Answer:
Answer: 112°
Step-by-step explanation:
Angles in a Circle
An inscribed angle is formed between two chords whose vertices lie on the circumference of a circle. The figure shows three chords: TU, SU, and ST. SU happens to also be a diameter because it goes through the center of the circle V.
ST and SU form an inscribed angle of 34°. The corresponding central angle is TVU and its measure is
[tex]m\angle TVU=2*34^\circ=68^\circ[/tex]
The required measure of the arc ST is the measure of the angle SVT. Note that SVT and TVU are complementary, thus:
[tex]m\angle TVU+m\angle SVT=180^\circ[/tex]
Solving for the measure of SVT:
[tex]m\angle SVT=180^\circ-m\angle TVU[/tex]
[tex]m\angle SVT=180^\circ-68^\circ=112^\circ[/tex]
