x = -12

Step-by-step explanation:

Let's solve your equation step-by-step.

8+x=−4

Step 1: Simplify both sides of the equation.

x+8=−4

Step 2: Subtract 8 from both sides.

x+8−8=−4−8

x=−12

ikadub [295]

Standard form is Ax +By =c

y = -4/5 x -7

multiply by 5

5y = -4x -35

add 4x to each side

4x +5y = -35

multiply by -1

-4x -5y = 35

In bold answers with correct units

3) 6 x 3 = 18 + 1/2 x 12 x 15 = 90 = 90+ 18 = 108ft^2

4) = 12 x 12 = 144 + 4x4 = 16 +12 x 4 = 48 = 144+12+48 = 204m^2

5) = 8 x 12 = 96 + 1/2 x 4 x 6 = 12 = 108ft^2

6) = 3x 3 = 9 + pi3^2 = 28.2743339 (x2) =56.5486678 + 9 = 65.5m^2

proves 4 semi circles = 2 circles

7) 10 x 8 = 80 +4 x 4 = 16 + 1/2 x 2 x 4 = 4 = 20+80= 100ft^2

proves 14-8-4 = 2ft is the triangle length and 10-6 = 4 the triangle height.

8) 4x6 = 24 + 1/2 x 4 x 2 = 4 + pi 4^2 = 1/2 x 50.2654825 = 24+4 + 25.1329 = 53.1m^2

Mark Went to the store and purchase nine pairs of socks and three packages of undershirts for $8.28 each he also purchase a pair

agasfer [191]

Answer:

He paid $2.35 for each pair of socks.

An equation using the variable S is

$77.99 = 9S + (3 × $8.28) + $32

Step-by-step explanation:

Let S be the cost of a pair of socks

From the question, Mark purchase nine pairs of socks, that is, the total cost of the pairs of socks is 9S

He purchase three packages of undershirts for $8.28 each; the total cost of the three packages of shirt will be 3 × $8.28 = $24.84

and he also purchase a pair of pants for $32

Since he spent a total of $77.99, we can write that

$77.99 = 9S + (3 × $8.28) + $32

Now, we can determine S, the cost of a pair of socks

$77.99 = 9S + (3 × $8.28) + $32

$77.99 = 9S + $24.84 + $32

$77.99 = 9S + $56.84

9S = $77.99 - $56.84

9S = $21.15

S = $21.15/9

S = $2.35

Hence, he paid $2.35 for each pair of socks.
