Solve for x.
5x + 3 = 2(x + 3) + 3x – 6
9514 1404 393
Answer:
no solution
Step-by-step explanation:
We can eliminate parentheses and collect terms.
5x +3 = 2x +6 +3x -6
5x +3 = 5x
3 = 0 . . . . . . . . subtract 5x from both sides
There is no value of x that will make this true. There is no solution.
Answer:
No solution
Step-by-step explanation:Does that make sense to u, You distribute 2 with x and 3 which gets you 2x+6. Combine like terms and you will get 5x on the right side, since the 6's cancel out. 5x+3=5x.
X cancels out and u are left with 3=nothing which makes it no solution

The soccer team is conducting a fundraiser selling long-sleeved T-shirts for $14 and short-sleeved T-shirts for $10. So far the team has sold less than $200 worth of the two types of T-shirts. Which inequality best represents x, the number of long-sleeved T-shirts they have sold, and y, the number of short-sleeved T-shirts they have sold?
x + y 200
14x + 10y > 200
14x + 10y < 200
The final statement is: The inequality is 14x+10y<200
What is an inequality?An inequality is an inequation separated by <,>≥,≤. In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”.
Given here: Total sales is less than$200, price of long sleeved T-shirts=$14
and short-sleeved T-shirt=$10
Then let x and y long and short sleeved T-shirts be sold respectively.
∴ 14x+10y<200
Hence, The inequality is 14x+10y<200

help pls thank u guys <33
Answer:
4600
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4
This indicates the sequence is arithmetic with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = 4 , thus
[tex]S_{50}[/tex] = [tex]\frac{50}{2}[/tex] [ (2 × - 6) + (49 × 4) ]
= 25(- 12 + 196)
= 25 × 184

Answer:
- 23/13
Step-by-step explanation:
1. Subtract 5/2 from both sides of the equation.
2. Simplify
7/5 = /10 − 23/10
3. Multiply all terms by the same value to eliminate fraction denominators.
7/5 = /10 − 23/10 2 ⋅ 5 ⋅ 7/5 = 2 ⋅ 5( /10 − 23/10)
4. Simplify
14 = − 23
5. Subtract from both sides of the equation.
14 = − 23 14 − = − 23 −
6. Simplify
13 = − 23
7. Divide both sides of the equation by the same term.
13x = −23 13x/13 = -23/13
8. Simplify
= −23/13

Line 1, Line 2 ,or the systems of equations
Answer:
Line 2
Step-by-step explanation:
An ordered pair of a coordinate is writted ( x , y ). So you can plug in the X and Y values from the ordered pair into the Lines.
Line 2 will look like this: -3(-2) - 2(5) = 4
Once you input the variables you can solve from there.
If the answer comes out like this 4=4 then it is true.
If the answer comes out like this 5=4 then it is not true, since 5 does not equal 4.

Which pair of triangles cannot be proved
congruent?
9
Which pair of triangles cannot be
proved congruent
B.
C.
D.
A
Option B pair of triangles cannot be proved congruent.
What is congruence?Congruence in two or more triangles depends on the measurements of their sides and angles. Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal. They are of the same shape and size.
SSS Criterion for Congruence
SSS criterion stands for Side-Side-Side criterion. Under this criterion, two triangles are congruent if three sides of a triangle are equal to the corresponding sides of the other triangle.
SAS Criterion for Congruence
SAS criterion stands for Side-Angle-Side criterion. Under this criterion, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
ASA Criterion for Congruence
ASA criterion stands for Angle-Side-Angle criterion. Under the ASA criterion, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.
AAS Criterion for Congruence
AAS criterion stands for Angle-Angle-Side criterion. Under the AAS criterion, two triangles are congruent if any two angles and the non-included side of one triangle are equal to the corresponding angles and the non-included side of the other triangle.
According to the question
Option A :
SAS : A triangle with equal sides and equal angles.
Option C :
SSS : A triangle with equal sides.
Option D :
AAS : A triangle with two equal angles and one equal side.
Option B :
These pair of triangles cannot be proved congruent.
Two triangles with equal corresponding angles may not be congruent to each other because one triangle might be an enlarged copy of the other. Hence, there is no AAA criterion for congruence.
