<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:
By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
Answer:
32/139
Step-by-step explanation:
There are a total of 42 + 45 + 20 + 32, or 139, candies in the bag.
The probability that the picked candy is purple is therefore
32
---------
139
This result cannot be simplified.
Answer:
x = 4.5
Step-by-step explanation:
First, we can subtract 2 from 20 (20 - 2) to get 18.
Now we know that x has to be multiplied by 4 and have a product of 18.
We can divide 18 by 4 to figure out what x is.
18 ÷ 4 = 4.5
We can check our answer by solving the equation:
4(4.5) + 2 = 20
18 + 2 = 20
20 = 20
(sorry if this is confusing but I hope it helped)
2, the answer is 2, otherwise spelled as two
Answer:
The answer is below
Step-by-step explanation:
AD = X + 8 ∠D = 2y +13 ∠C = 16 - x CB = 5y+4
In a parallelogram, consecutive angles are supplementary and opposite sides are equal.
Therefore for parallelogram ABCD, AB = CD, CB = AD
Since AD = CB (opposite sides of a parallelogram are equal):
x + 8 = 5y + 4
5y - x = 8 - 4
5y - x = 4 (1)
∠C + ∠D= 180° (consecutive angles of a parallelogram are supplementary). Therefore:
16 - x + 2y + 13 = 180
2y - x + 29 = 180
2y - x = 180 -29
2y - x = 151 (2)
To find x and y, subtract equation 1 from equation 2:
3y = -147
y = -49
Put y = -49 in equation 2
2(-49) - x = 151
x = -98 - 151
x = -249
