1.8 - 0.2x = -1.6         Subtract 1.8 on both sides

1.8 - 1.8 - 0.2x = -1.6 - 1.8

-0.2x = -3.4        Divide -0.2 on both sides

\frac{-0.2x}{-0.2}=\frac{-3.4}{-0.2}

x = 17

6x-y=-23 8x+3y=-9 Substition method (Show it step by step please!)
Tanya [424]

Answer:

solution is (- 3, 5 )

Step-by-step explanation:

given the 2 equations

6x - y = - 23 → (1)

8x + 3y = - 9 → (2)

rearrange (1) expressing y in terms of x

y = 6x + 23 → (3)

Substitute y = 6x + 23 into (2)

8x + 3(6x + 23 ) = - 9

8x + 18x + 69 = - 9

26x + 69 = - 9 ( subtract 69 from both sides )

26x = - 78 ( divide both sides by 26 )

x = - 3

substitute x = - 3 into (3)

y = (6 × - 3 ) + 23 = - 18 + 23 = 5

solution is (- 3, 5 )

Simplify the expression the root of negative sixteen all over the quantity of three minus three i plus the quantity of one minus
aliya0001 [1]
The first step is to multiply the fraction by (3 +3i) / (3 +3i) to delete the i terms from the denominator:

\frac{ \sqrt{-16} }{3-3i} . \frac{3+31}{3+3i} +1-2i=  \frac{4i(3+3i)}{9+9} +1-2i= \frac{12i-12}{18} +1-2i=

\frac{12i-12+18-36i}{18} = \frac{6-24i}{18} = \frac{1}{3} - \frac{4}{3} i

A farmer grows two types of grain in his fields. he has a seed budget of $20,000.00 and has spent $11,200.00 to plant wheat seed
Arisa [49]
For the answer to the question above, I'll provide a solution below.
52x < = 20,000 - 11200
52x < = 8800
x < = 8800/52
x < = 169.23
So the answer to your question is 169 acres <span>of barley the farmer can plant and still be under budget.
I hope my answer helped you. have a nice day!</span>
