Leo had $91, which is 7 times as much money as Alison had. How much

NARA [144]

Answer:

$7x=91$

$13.

Step-by-step explanation:

Let x represent money that Alison has.

We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be $7x$ .

We are also told that Leo had $91, so we will equate $7x$ with 91 and solve for x as:

$7x=91$

To solve for x, we will divide both sides by 7:

$\frac{7x}{7}=\frac{91}{7}$

$x=13$

Therefore, Alison has $13.

<h2>GIVEN - </h2>

Water tank which is in a shape of right rectangular prism

Dimensions = 6 feet × 4 feet × 7 feet

Surface area of tank

<h2>SOLUTION - </h2>

Using formula of surface area of right rectangular prism -

Surface area =

$2(wl + hl + hw)$

L = length

w = width

h = height

( assumimg 6 feet = L , 4 feet = W , 7 feet = h)

Putting value of L, W and H in the equation. we get,

=2(4 × 6 + 7 × 6 + 7× 4)

= 2(24 + 42 + 28)

= 2( 94)

= 2 × 94

= 188
