Zen spent $255 on a bag and a belt. She wanted to buy another
Galina-37 [17]

Answer:

A)$ 45

B) $105

Step-by-step explanation:

Bag and a belt cost $255

Let bag = x

Let belt = y

X+y= 255 equation 1

Let total money be z first

Remaining money= z-255

X-30 = z-255

Y +15 = z-255

Equating the left side of the equation

X+30 = y+15

X-y= 45 equation 2

Solving simultaneously

X+y= 255

X-y= 45

2x = 300

X= 150

If x= 150

150-y= 45

150-45= y

105=y

Bag = $150

Belt = $105

Bag Is 150-105 more than the belt

150-105= $45

Gelneren [198K]

Answer:

The pressure at 50 feet is 2.51515 atm

Step-by-step explanation:

we are given equation as

p(d)=1+\frac{d}{33}

where

p(d) gives the​ pressure, in atmospheres​ (atm)

a depth d in the sea​ (d is in​ feet)

We are given

d=50 feet

So, we can plug d=50 and find p

p(50)=1+\frac{50}{33}

p(50)=2.51515atm

So,

The pressure at 50 feet is 2.51515 atm
