Answer:
x = 3
y = 0
Step-by-step explanation:
x + 2y = 3 ---------eqn 1
x - y = 3 --------eqn 2
Using eqn 2 to find the value of y
x - y = 3
Making y the subject of the formula
x - 3 = y
y = x - 3
Substitute the value of y into eqn 1
x + 2y = 3
x + 2(x - 3) = 3
Open the bracket
x + 2x - 6 = 3
3x - 6 = 3
3x = 3 +6
3x = 9
Divide both sides by 3, to get value of x
3x/3 = 9/3
x = 3
To get the value of y, use eqn 2
x - y = 3
3 - y = 3
3 - 3 = y
y = 0
Hint, to know maybe the values are correct, insert the values into the equation
Let's use eqn 2
x - y = 3
x = 3
y = 0
Insert into the equation
x - y = 3
3 - 0 = 3
Our values are correct
<u>Answer</u>
C. 38
<u>Explanation</u>
The absolute value of any digit is the magnitude or its size. The negative side is not considered.
It can also be defined as the actual magnitude of a numerical value or measurement, irrespective of its relation to other values.
It is represented as; /x/.
The absolute value of -38 is /-38/.
∴ /-38/ = 38
Answer:
1/13 (1 in 13)
Step-by-step explanation:
so, there's 4 aces in a standard deck of 52 cards.
so far, we can see this as 4/52 (4 in 52)
these are both divisible by 2, lets go ahead and simplify that to 2/26
still divisible by 2. this then becomes 1 /13
so, she has a 1/13 (1 in 13) chance to get an ace.
10:40 because yellow goes before the total. Or it is 25%
Answer:
C(x)= 41x + 680
Step-by-step explanation:
If the fixed cost is 680, that will apply regardless of how many jackets the company makes for you. The number of jackets is unknown. However, we know that the cost of producing a single jacket is 41, so we can represent that expression as 41x. Putting those things together gives us a function of the cost:
C(x) = 41x + 680
