Hey there! :)
Equation 1) 4x = y - 1
Equation 2) 6x - 2y = -3
We want both equations to match in a sense where both x & y are on the same side of the equal sign. To achieve this, simply subtract y from both sides in equation 1.
This will leave us with : 4x - y = -1
Now, line up the equations with one another.
1) 4x - y = -1
2) 6x - 2y = -3
Now, multiply 2 to ALL of equation 1.
2(4x - y = -1)
Simplify.
8x - 2y = -2 → We'll call this new equation 3. Now, line up equation 3 with equation 2.
6x - 2y = -38x - 2y = -2
Subtract equations from one another.
-2x = -1
Divide both sides by -2.
-2x ÷ -2 = -1 ÷ -2
Simplify.
x = 1/2
Now, plug in 1/2 for x into our first equation.
4x - y = -14(1/2) - y = -1
Simplify.
2 - y = -1
Subtract 2 from both sides.
-y = -1 - 2
Simplify.
-y = -3
Divide both sides by -1.
y = 3
So, our answer is : x = 1/2, y = 3 OR (1/2, 3)
~Hope I helped!~
Answer:
A) 3hrs
Step-by-step explanation:
Fission is the action of dividing or splitting something into two or more parts.
So, we're going to continuously multiply our answers by 2 until we get 360
10 x 2 = 20 30min
20 x 2 = 40 1hr
40 x 2 = 80 1hr 30min
80 x 2 = 160 2hrs
160 x 2 = 320 2hrs 30min
320 x 2 = 630 3hrs
Answer:
Step-by-step explanation:
72
The answer would be rounded up to 40,000 because of 5 in place value goes. up not down.
Answer:
SAT
Step-by-step explanation:
The two main college entrance exams are the SAT and ACT which are used for almost all colleges in the United States. Between these two the SAT has a lesser focus on math in general. Instead, the SAT tends to focus more on word problems and the process taken to solve them. This does not mean that it has no math at all, there is still a math section on the SAT's but it is not as extensive as in the ACT's.
