Step-by-step explanation:

Let x b number, according to instructions´ we must

1.-Multiply by 4

2.-Subtract 6

3.-Divide by 2

4.-Arturo says his new number - 15

4,.Which one was the original number ??

The maths expression for that is :

(4*x - 6 ) / 2 = - 15

we solve for x

4x - 6 = - 30

4x = - 24

x = - 6

Convert the fraction to higher terms. Enter the value of the missing numerator. 3/11= /77?

$\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}$

<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

please help!!! the study conducted was 6 days long: there was 72mm of plant food and it decreased an equal amount each day.

Anuta_ua [19.1K]

Answer:

$f(x) = 72 - 12x$

Step-by-step explanation:

No. of days of study = 6

Amount of food to use for the 6 days = 72 mm

Given that equal amount of food was used each day, amount used per day = $\frac{72}{6} = 12 mm$

This would enable us derive a function for the amount of food remaining f(x), which can be expressed as a function of the number of days that have passed, (x).

Thus, we would have:

$f(x) = 72 - 12x$

Let's check if this equation expresses the relation of the function well.

At the end of day 1, if we used, 12mm, we would have 72 - 12 = 60mm of food remaining.

If we replace x in the equation we derived, we would get the same 60mm as the amount of food remaining.

If you try 2, 3, 4, 5 days, you'd get same thing.

At the end of the study, after the 6th day, the food would remain nothing.

Replace 6 for x in the relation function derived, you'd get a value of 0.
