2.7x -9 = x +7.5 need the answer can't find solution.
Answer:
x = 9.7
Step-by-step explanation:
2.7x -9 = x +7.5
2.7x - x = 7.5 + 9
1.7x = 16.5
x = 16.5/1.7
x = 9.7
Answer:
x = 9.70588
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
2.7x - 9 = x + 7.5
Step 2: Solve for x
Subtract x on both sides: 1.7x - 9 = 7.5Add 9 on both sides: 1.7x = 16.5Divide 1.7 on both sides: x = 9.70588Step 3: Check
Substitute in x into the original equation to verify it's a solution.
Substitute in x: 2.7(9.70588) - 9 = 9.70588 + 7.5Multiply: 26.2059 - 9 = 9.70588 + 7.5Subtract/Add: 17.2059 = 17.2059Here we see that 17.2059 does indeed equal 17.2059.
∴ x = 9.70588 is a solution of the equation.
Solve the equation. -3(-7-x)=1/2(x+2).

Find AT AND RC. 80 points
Answer:
AT=6, RC=5
Step-by-step explanation:
Perpendicular bisector intersect at T that is the circumcenter.
since RT is a bisector or AC and AR=5 then RC=5
Circumcenter is equidistant from the vercices of the triangle so
AT≅BT≅CT

find the slope of the line PLEASE
Given the graph, we can determine the slope, and use slope formula* to prove it.
Points: (-4, 1) and (-2, -1)
From the graph, the slope of the line is -1, mean the line goes down 1 unit and left 1 unit.
To prove this you can use slope formula*:
[tex]m = \frac{-1 - 1}{-2 + 4} = \frac{-2}{2} = -1[/tex]
*Slope formula: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

HELP! The Question is "Select All Ordered pairs that satisfy the function y=4x + 3.
Answer: see explanation
Step-by-step explanation: To determine which ordered pairs satisfy the equation substitute the x coordinate of the point into the right side and if the value obtained equals the y coordinate of the point then it satisfies the equation
(- 1, - 1)
x = - 1 : y = - 4 + 3 = - 1 ⇒ (- 1, - 1) satisfies the equation
(2, 11)
x = 2 : y = 8 + 3 = 11 ⇒ (2, 11) satisfies the equation
(4, 7)
x = 4 : y = 16 + 3 = 19 ≠ 7 ⇒ (4, 7) does not satisfy the equation
(7, 1)
x = 7 : y = 28 + 3 = 31 ≠ 1 ⇒ (7, 1) does not satisfy the equation

HELPPP
Answer:
Undefined.
Step-by-step explanation:
m = y2-y1 / x2-x1
m = 3 - 2 / 1 - 1
m = 1/0, which is undefined.
You can also tell because (1,2) and (1,3) is a vertical line, which means the slope is undefined.

the difference between 13 fours and 6 fours
Answer:
The lesson activity requires students to use up to four fours and any operation to make the numbers from 0 to 100. For example, 4 + 4 + 4 + 4 = 16.
Initially, students will use the more familiar operations, +, −, ×, ÷, along with brackets to create their equations. For example, (4 × 4 + 4) ÷ 4 = 5. Gradually, finding solutions for the remaining numbers in the list becomes more challenging. Here, it is a good opportunity to introduce some other operations to the students, including √4 = 2 and 4! = 24. In my experience, at least one student in the class will be familiar with the square root operation √n, which will make it easier to introduce. The other operation n!, known as factorial, will be less familiar to students.
n! is the product of all positive integers less than or equal to n; for example, 4! = 4 × 3 × 2 × 1 = 24, or 3! = 3 × 2 × 1 = 6
With the introduction of these two less familiar operations, the number of solutions that students can find to the initial problem increases.

Sophie practices the piano 105 minutes in 1 week. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context.
Answer:
t = 15dStep-by-step explanation:
You must first know that 1 week = 7days
If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;
105 minutes = 7days
to calculate the total time t that she practices for any number of days, d, we will say;
t minutes = d days.
Solving both expression;
105 minutes = 7days
t minutes = d days.
Cross multiply;
7 * t = 105 * d
7t = 105d
Divide both sides by 7;
7t/7 = 105d/7
t = 15d
Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d
