Answer:
<h3>B. 9/4</h3>
Step-by-step explanation:
According to the diagram, there are 5 x's in and 8 of negative 1 in the left hand side of the equation. This is represented mathematically as;
= 5x+8(-1)
= 5x - 8 .............. 1
In the right hand side, there are 3 of -x's and 1 in 10 places. This is also expressed as;
= -3x+1(10)
= -3x+10 ............ 2
Equate 1 and 2 and find x
5x-8 = -3x+10
add 7 to both sides
5x-8+8 = -3x+10+8
5x = -3x+18
add 3x from both sides
5x+3x = -3x+18+3x
8x = 18
x = 18/8
x = 9/4
Hence the value of x that makes the equation true is 9/4
Answer:
$3.00
Step-by-step explanation:
5x + 3y = 30 - - - - - 1 x 4
3x + 4y =29 - - - - - -2 x 3
--------------------------------------------
20x +12y = 120 - - - - 3
9x + 12y = 87 - - - - - 4
--------------------------------------------
3-4
20x - 9x= 120 - 87
11x = 33
X= 33
11
X = 3
Answer:
Let affan have x no. of stamps Then,
According to the question Ayaan has 20 stamps more than 3 times the number of stamps Affan has. Then,
x = 3x + 20
Now they both have 140 stamps all together. so,
x + 3x + 20 = 140
or, 4x = 140 - 20
or x = 120/4
or, x = 30
Therefore, Affan has 30 stamps .
