Answer:
0.200
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-4-(-4*x-2)=0
Step by step solution :
STEP 1
1.1 Pull out like factors :
10x - 2 = 2 • (5x - 1)
STEP 2
2.1 Solve : 2 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : 5x-1 = 0
Add 1 to both sides of the equation :
5x = 1
Divide both sides of the equation by 5:
x = 1/5 = 0.200
solution:
x = 1/5 = 0.200
Answer:
21
Step-by-step explanation:
8x+y, when x=2 and y=5,
then 8*2+5. Because the 2 is right next to the 8, it isn't '82', but '8*2'
According to PEMDAS, multiplication is done first, so
8*2= 16,
16+5, which is 16+5= 21
<span>6x – 7y = 16
2x + 7y = 24
This system is easily solvable by the elimination method as the y-terms are opposites of each other. You may add the two equations together and they will cancel out.
</span> 6x – 7y = 16
2x + 7y = 24
+___________
8x – 0 = 40
8x = 40
x = 5
Substitute 5 for x into either of the above equation and solve algebraically for y.
2x + 7y = 24
2(5) + 7y = 24
10 + 7y = 24
7y = 14
y = 2
Check work by plugging both x- and y-values into each original equation.
6x – 7y = 16 => 6(5) – 7(2) = 16 => 30 – 14 = 16
2x + 7y = 24 => 2(5) + 7(2) = 24 => 10 + 14 = 24
Answer:
x = 5; y = 2
(5, 2)
A proportion<span> is a name we give to a statement that two ratios are equal. It can be written in two ways: two equal fractions, or, using a colon, a:b = c:d.</span>
IT WOULD BE "D" I BELIEVE
HOPE IM RIGHT AND THIS HELPS
