Which sentence is true?

Answer:

11.7

Step-by-step explanation:

Step-by-step explanation:

2n+1+2n+3+2n+5+2n+7

8n+16=40

8n=40-16

8n=24

n=3

Answer AND expaination

The product of a number and 3 increased by 5 is 7 less than twice the number which equation can be used to find this number , n?

its -7

the product of a number and 3: 3n

increased by 5: + 5

7 less than: - 7

twice the number: 2n

That gives us the following:

3n + 5 = 2n - 7

You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

Answer:

About 31 days

Step-by-step explanation:

Since he already has $125, you can subtract that amount from how much he needs to earn. $400 - $125 = $275 that he must earn.

Divide the remaining amount by how much he earns a day to find the number of days he must work to reach his goal.

$275 ÷ $9 ≈ 30.5 (I got 30.5 repeating). I rounded up to 31 days.

Answer:

(d) and (e) are true

Step-by-step explanation:

Given

[tex]Food = 23\ oz[/tex]

See attachment for proper presentation of question

Required

Select all true statements

For any option to be true, it must satisfy the following condition.

[tex]Days * Food = 23[/tex]

Option (a):

[tex]Days = 6[/tex]

[tex]Food = 4\frac{1}{6}[/tex] per day

So, we have:

[tex]Days * Food = 6 * 4\frac{1}{6}[/tex]

[tex]Days * Food = 6 * \frac{25}{6}[/tex]

[tex]Days * Food = 25[/tex]

This is not true because: [tex]25 \ne 23[/tex]

Option (b):

[tex]Days = 10[/tex]

[tex]Food = 2\frac{2}{23}[/tex] per day

So, we have:

[tex]Days * Food = 10 * 2\frac{2}{23}[/tex]

[tex]Days * Food = 10 * \frac{48}{23}[/tex]

[tex]Days * Food = \frac{480}{23}[/tex]

[tex]Days * Food = 21[/tex] --- approximated

This is not true because: [tex]21 \ne 23[/tex]

Option (c):

[tex]Days = 8[/tex]

[tex]Food = 3\frac{1}{8}[/tex] per day

So, we have:

[tex]Days * Food = 8 * 3\frac{1}{8}[/tex]

[tex]Days * Food = 8 * \frac{25}{8}[/tex]

[tex]Days * Food = 25[/tex] --- approximated

This is not true because: [tex]25 \ne 23[/tex]

Option (d):

[tex]Days = 11[/tex]

[tex]Food = 2\frac{1}{11}[/tex] per day

So, we have:

[tex]Days * Food = 11 * 2\frac{1}{11}[/tex]

[tex]Days * Food = 11 * \frac{23}{11}[/tex]

[tex]Days * Food = 23[/tex] --- approximated

This is true because: [tex]23 = 23[/tex]

Option (e):

[tex]Days = 7[/tex]

[tex]Food = 3\frac{2}{7}[/tex] per day

So, we have:

[tex]Days * Food = 7 * 3\frac{2}{7}[/tex]

[tex]Days * Food = 7 * \frac{23}{7}[/tex]

[tex]Days * Food = 23[/tex] --- approximated

This is true because: [tex]23 = 23[/tex]

Answer:

Step-by-step explanation:

you can think they come in pairs :

3 crates and 5 boxes = 8 (crates +boxes)

40 (crates+ boxes) are maximum to be hold so we can have 40/8 = 5 such pairs

the truck can hold

3 *5 = 15 crates and 5 *5 =25 boxes

Step-by-step explanation:

120+25x=195

If you add 25 to 120, 3 times you get 195.

Therefore your answer is 3 months.

Mark brainliest pls and thank you.

The domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex].

The composition of two functions consists in replacing the variable of the former function ([tex]b(x)[/tex]) by the latter function ([tex]a(x)[/tex]). If we know that [tex]b(x) = \sqrt{x-4}[/tex] and [tex]a(x) = 3\cdot x +1[/tex], then the composite function:

[tex]b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}[/tex]

[tex]b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}[/tex]   (1)

Since the composite function is a square root function, then the domain fulfill the following inequation:

[tex]3\cdot x -3 \ge 0[/tex]

[tex]x \ge 1[/tex]

Hence, the domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex]. [tex]\blacksquare[/tex]

Step-by-step explanation:

Answer:

coin us the right anwser

Answer:

OPTION D

Explanation:

For zeros of the function (y is the function, a function of x) we need y = 0 so that in turn means we need - 9x - 1 = 0 or - 9x = 1 (i.e. add 1 to both sides); now divide by - 9, and x = 1/-9 which is exactly the same as - 1/9 or - (1/9) and this is the only zero of the function.

or

If y = -9x - 1,

When y = 0

0 = -9x - 1

0 + 1 = -9x - 1 + 1

1 = -9x

1/9 = -9x/9

1/9 = -x

1/[9 X (-1)] = -x/-1

- (1/9) = x

When x = 0

y = (-9 X 0) - 1

y = 0 - 1

y = - 1

The area of a triangle  A = 46.399 square units

Step-by-step explanation:

Explanation:-

Given that ΔABC

Given ∠ A = 42.5° and sides b= 13.6 and c =10.1

The area of a triangle

                [tex]A = \frac{1}{2} b c sin A[/tex]

                [tex]A = \frac{1}{2} 13.6(10.1) sin 42.5[/tex]

                [tex]A = \frac{1}{2} 137.36(0.67559)[/tex]         (∵ sin (42.5)° = 0.67559

               A = 46.399 square units
