Answer:

Step-by-step explanation:

At most, the area is 140 ---> the area is (3x + 2)10

So, as an inequality, you get (3x + 2) 10 ≤ 140

Simplify

30x + 20 ≤ 140

30x ≤ 120

x ≤ 4

Can 3x + 2 be 15?

Plug in the greatest value of x, and get 3*4 + 2, which is 12 + 2, which is 14

No, at most the length can be 14, which is less than 15.

1. Mr. Samuel had 13 notes in his wallet. They consist of $1. $5 and $10 notes. The total amount of the notes adds up to $93. Ho

bazaltina [42]

Answer:

8 $10 notes

Step-by-step explanation:

I started by working it backwards. $93-$3 equals $90. So we have three of our 13 notes. We need ten more. Well the most $10 notes we can have is 8. if we had 8 $10 notes that would give us $80. $90-$80=10. We can take ten and divide it by five so we have 2 $5 notes.

So in total he would have 8 $10 notes, 2 $5 notes, and $3 one dollar notes which adds up to 13 notes

A snail traveled 3 over 8, of an inch in 3 minutes. How many inches can the snail travel in 9 minutes? Express the answer as a d

Elanso [62]

So, first of all, let's convert the fraction $\frac{3}{8}$ into a decimal, which would be 0.375 (3 divided by 8)

The snail travels this far in 3 minutes. To find out how far it travels in nine minutes, we have to find out how many times 3 goes into 9.

9 / 3 = 3

Now. we simply multiply our decimal by three in order to get our answer!

0.375 x 3 = 1.125 inches

The answer is 1.125 inches!

Given f (x) = -4x + 4, solve for x when f (x) = 0

Kazeer [188]

Answer:

x = 1

Step-by-step explanation:

Given:

f(x) = -4x + 4
f(x) = 0

We are asked to solve for x when the function is equal to zero.

<u>We should have</u>: 0 = -4x + 4

<u>Solve</u>

1. Subtract 4 from both sides

0 - 4 = -4x + 4 - 4

-4 = -4x

2. Divide both sides by -4

-4 ÷ -4 = -4x ÷ 4

1 = x
