Answer:

x=8

Step-by-step explanation:

4x+2=5x-6

Subtract 4x from each side

4x-4x+2=5x-4x-6

2 =x-6

Add 6 to each side

2+6 = x-6+6

8 =x

John runs to the market and comes back in 15 minutes. His speed on the way to the market is 5m/s and his speed on the way back i

katen-ka-za [31]

Answer:

The distance to the market is 2000 m

Step-by-step explanation:

∵ John runs to the market and comes back in 15 minutes

→ Change the min. to the sec. because the unit of his speed is m/s

∵ 1 minute = 60 seconds

∴ 15 minutes = 15 × 60 = 900 seconds

→ Assume that t1 is his time to the market and t2 is his time from

the market

∵ t1 + t2 = 15 minutes

∴ t1 + t2 = 900 ⇒ (1)

→ Assume that the distance to the market is d

∵ His speed on the way to the market is 5m/s

∵ Time = Distance ÷ Speed

∴ t1 = d ÷ 5 ⇒ (1 ÷ 5 = 0.2)

∴ t1 = 0.2d ⇒ (2)

∵ His speed on the way back is 4m/s

∴ t2 = d ÷ 4 ⇒ (1 ÷ 4 = 0.25)

∴ t2 = 0.25d ⇒ (3)

→ Substitute (2) and (3) in (1)

∵ 0.2d + 0.25d = 900

∴ 0.45d = 900

→ Divide both sides by 0.45

∴ d = 2000 m

∴ The distance to the market = 2000 m

What is the answer i'll give brainly

egoroff_w [7]

Answer:

c = -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

$4(-2)=4*\frac{-c-11}{4}$

Cancel multiplied terms that are in the denominator

$4(-2)=-c-11$

Multiply the numbers

$-8=-c-11$

Add 11 to both sides of the equation

$-8+11=-c-11+11$

Simplify

$3=-c$

Divide both sides of the equation by the same term

$\frac{3}{-1}=\frac{-c}{-1}$

Simplify

$c=-3$

Solve for x does anyone know how to do this?

riadik2000 [5.3K]

Answer:

x = 9

Step-by-step explanation:

The sum of the 4 angles in a quadrilateral = 360°

Sum the given angles and equate to 360

90 + 109 + 9x - 5 + 85 = 360, that is

9x + 279 = 360 ( subtract 279 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9
