Answer:
A
Step-by-step explanation:
Given the 2 equations
2x + y = 13 → (1)
x - y = - 4 → (2)
Add the 2 equations term by term to eliminate the y- term, that is
3x = 9 ( divide both sides by 3 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 13
6 + y = 13 ( subtract 6 from both sides )
y = 7
solution is (3, 7 ) → A
Answer:
-3.65 *Can I have brainliest plz?
Step-by-step explanation:
Shift the decimals of both 27.375 and 7.5 to the right by 1 decimal place. (This is needed to convert 7.5 to 75, since long division must divide by a whole number.)
273.75\div 75273.75÷75
Use the algorithm method.
3 . 6 5
7 5 | 2 7 3 . 7 5
2 2 5 .
4 8 . 7
4 5 . 0
3 . 7 5
3 . 7 5
Now consider the signs. One number is positive, and the other number is negative. Therefore, the result will be negative.
-27.375,7.5 \rightarrow \text{Negative}−27.375,7.5→Negative
Therefore, -27.375\div 7.5=-3.65
-3.65

To use the distributive property, we need to understand the formula to use it. This formula will ensure that you can easily solve any equation.
The distributive property is A(B + C) = AB + AC, where AB is the product of the values A and B and AC is the product of the values A and C.
First, let's notice that we are distributing a 2 into the parentheses, so we will mark this as our A value.
Then, our two values inside the parentheses are B and C respectfully.
