It takes 60 minutes for 4 people to paint 8 walls.

1 answer:

8 0

Each person paints 2 walls in 60 minutes ( 8:4=2) that means 1 wall takes 30 minutes for each person( 60:2=30)

For 9 walls , each person paints 1.5 walls ( 9:6= 1.5) that mean 1.5 * 30= 45 minutes

So 6 people need 45 minutes to paint 9 walls

-377 = x - 1,000 i dont under stand it

Naddika [18.5K]

Answer:

$\boxed {x = 623}$

Step-by-step explanation:

Solve for the value of $x$ :

$-377 = x - 1,000$

-Switch sides:

$-377 = x - 1,000$

$x - 1,000 = -377$

-Add $1,000$ on both sides:

$x - 1,000 + 1,000 = -377 + 1,000$

$\boxed {x = 623}$

Therefore, the value of $x$ is $623$ .

Slope is –2 & (5, 3) is on the line. Y-Intercept: Equation of the line (no spaces):

insens350 [35]

Answer:

y-int: (0, 13)

Equation: y = -2x + 13

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m = slope

b = y-intercept

Step 1: Define variables

m = -2

Random point (5, 3)

Step 2: Plug in known variables

y = -2x + b

Step 3: Find y-intercept b

3 = -2(5) + b

3 = -10 + b

b = 13

Step 4: Rewrite equation

y = -2x + 13

The first term of an arithmetic sequence is-3 and the 15 term is 53. What is the common difference of the sequence?

Annette [7]

$a_2=a_1+d$
$a_3=a_2+d=a_1+2d$
$a_4=a_3+d=a_1+3d$
...
$a_{15}=a_1+14d$

Since $a_1=-3$ and $a_{15}=53$ , the common difference $d$ is

$53=-3+14d\implies d=4$
