Liliana buys some softballs at $3 each and gloves at $20 each for her PE
class. She buys twice as many balls as gloves. She spends $138 in total,
which includes $8 tax: Which equation would you use to find the number of
gloves she buys?
Let x represent the number of gloves she buys.
A. 2 + 2x + 8 = 138
B. 20 (2x) + 3 (x) + 8 = 138
C. 20 (2) + 3 (2x) + 8 = 138
D. 20 (x) + 3(2x) = 138
Answer:
d. 20(x)+3(2x)=138
ap3x
The number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3.
What are linear equation?A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now it is given that,
Cost of each softball , $3.
Cost of each gloves, $20 .
Total money spend , $138 .
Tax , $8 .
She buys twice as many softballs as gloves.
To Find the number of gloves she buys .
Let , x represent the number of gloves she buys.
So , number of softballs she buys is 2x .
20 (2x) + 3 (x) + 8 = 138
or, 40x + 3x + 8 = 138
or, 43x + 8 = 138
Subtract 8 both the side we get,
43x = 130
or, x = 3.02
0r, x = 3
Hence,the number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3

2(3x + 6) = 3( x - 9)
Answer:
x= - 13
Step-by-step explanation:
2(3x+6) = 3(x-9)
6x+12 = 3x -27
-3x -3x
3x+12=-27
-12 -12
3x= -39
/3 /3
x= - 13
Answer:
x = -13
Step-by-step explanation:
2(3x + 6) = 3( x - 9)
Distribute
6x +12 = 3x - 27
Subtract 3x from each side
6x-3x+12 = 3x-27-3x
3x+12 = -27
Subtract 12 from each side
3x+12-12 = -27-12
3x = -39
Divide by 3
3x/3 = -39/3
x = -13

what is the answer to this question im having trouble 3 x 2 - x?
Answer and Step-by-step explanation:
3 x 2 - x = ? Well, if you simplify it's just 5x. But, if you are trying to solve this then you have to know what x is or what your answer is. But, if you're trying to solve 3 x 2 = x then x would equal 6. Of course, if you know the answer or what x equals then plug it in as such, let's say x = 2 then you would plug 2 in for x and solve, 3 x 2 = 6 - 2 = 4. But, if you are trying to solve for x then look at the answer, let's say it is 24 so, 3 x 2 - x = 24, x would equal -18.

Solve for x in simplest form. 9=1/4 (6x+12)
Answer:
x=4
Step-by-step explanation:
9=1/4 (6x+12)
Multiply each side by 4
4*9 =4*1/4 (6x+12)
36 = (6x+12)
Subtract 12 from each side
36-12 = 6x+12-12
24 = 6x
Divide each side by 6
24/6 = 6x/6

If c – a = b, which of the following statements is true?
A. a + b = c
B. c + b = a
C. a – c = b
D. b – c = a
If c – a = b, then true statement is A. a + b = c
What is commutative property?The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.
Now the given statement is,
c – a = b
adding a to both the the side
c – a + a = b + a
⇒ c = b + a
Using commutative property of addition we get,
a + b = b + a
Therefore, we get
⇒ c = a + b
Thus the true statement is A. a + b = c
