Answer:

$- 3(x - 1) = - 1(5 - x) \\ \\ 3 - x + 1 = - 5 + x \\ \\ - x - x = - 5 - 3 - 1 \\ \\ - 2x = - 5 - 3 - 1 \\ \\ - 2x = - 9 \\ \\ x = \frac{ - 9}{ - 2} \\ \\ x = 4.5$

I need helpppp:

Sedaia [141]

Answer:

The second table.

Step-by-step explanation:

In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43. It decreases and then increases. This is not the correct table.

In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47. It increases and then decreases; this is the correct table.

To verify, we check the last two tables. The third table stays at 45, then decreases to 43 and 41. This is not correct.

The last table decreases from 45 to 43, then decreases to 41, then stays constant. This is not correct.

The second table is the only correct one.

Solve the following equation for x. Show each step. 5x + 2 = 3x + 4(2x - 1)

Reptile [31]

Answer:

$x=1$

Step-by-step explanation:

Start with:

$5x+2=3x+4(2x-1)$

Distribute the $4$ into $(2x-1)$ :

$5x+2=3x+8x-4$

Combine like terms:

$5x+2=11x-4$

Add $4$ to both sides of the equation:

$5x+6=11x$

Subtract $5x$ from both sides of the equation:

$6=6x$

Divide both sides of the equation by the coefficient of $x$ , which is $6$ :

$1=x$

$x=1$

ANSWER ALL (a-d) FOR 30 POINTS - EASY

djverab [1.8K]

Part a.

The perimeter formula is: P = 2w + 2L

Your answer for part A is P = 2w + 2L

Part b.

They tell us in part b, that:
w = 6L + 20

Substitute that into what we got for part a.

P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40

Your answer for partb is P = 14L + 40

Part c.

So we take what we got from part b, and solve for L.

P = 14L + 40
14L = P - 40

$L = \boxed{\frac{P-40}{14}}$

That is your answer for part 3 ^

part d.

Plug in w = 32 into what we first got in part b.

w = 6L + 20
32 = 6L + 20
6L = 12

L = 2

Your answer for part d is L = 2
