The length of a rectangle is 4 inches longer than it is wide. If the perimeter is 52 inches, what are the
dimensions of the rectangle?

Answer:

her brother is 15 years old

Step-by-step explanation:

let 'b' = her brother's age

Harriet is 3 years old but Harriet is also '1/3b - 2'

3 = 1/3b - 2

5 = 1/3b

b = 5(3) or 15

Answer:

The answer should be B

Step-by-step explanation:

Car A traveled farther at the same rate as Car B but A travelved more so  the answer is B

Answer:

B.

Step-by-step explanation:

Answer:

The value of x = 28°

Step-by-step explanation:

Explanation:-

Complementary angles:-

Two angles are called Complementary angles when their measures add to 90 degrees

         ∠A + ∠B = 90°

     (x+40)° + 22° = 90°

        x + 62° = 90°

        x = 90 - 62

        x = 28°

Answer:

Slope: 5/3

Step-by-step explanation:

Linear equation:

y = mx + b

m is the slope

so if,

y = 5/3x - 4

5/3 is the slope.

Respuesta: 28 billetes de 100 y 11 billetes de 200

Explicación paso a paso:

X=39-y

200(39-y)+100y=5000

7800-200x+100y=5000

-100y=2800

Y=2800/100

Y=28 billetes de 100

Step-by-step explanation:

Given

12a - 8 - 5a + 12

= 7a + 4

Hope it will help :)

Answer:

7a + 4

Step-by-step explanation:

First, let's rewrite this expression to combine like terms:

12a – 8 – 5a + 12  — I bolded the constants and underlined the expressions with variables

12a – 5a – 8 + 12  — it looks a little easier regrouped, doesn't it?

The last two terms are easy, right?

12 – 8 = 4  — simplify with subtraction

We'll focus on the first two terms now. Let's rewrite the terms with variables attached to make the subtraction easier:

a(12 – 5) = a(7) = 7a

We could also think of it this way: multiplication is just repeated addition.

12a = a + a + a + a + a + a + a + a + a + a + a + a (we just add a to itself 12 times)

5a = a + a + a + a + a (we just add a to itself 5 times)

Subtracting this expression would then look like this:

a + a + a + a + a + a + a + a + a + a + a + a – (a + a + a + a + a)

a + a + a + a + a + a + a + a + a + a + a + a – a – a – a – a – a

Five of the a values will cancel out, and to show this, we can rewrite the expression once more, like this:

a – a + a – a + a – a + a – a + a – a + a + a + a + a + a + a + a

The five a values cancel out and leave us with this:

a + a + a + a + a + a + a

How many a values are added together now? Seven of them, right? We add a to itself 7 times. We can then rewrite that expression as 7a.

Using the [12 – 8 = 4] expression from above, we add the 4 to the 7a to find our final answer: 7a + 4

I hope this helps increase your understanding of the concept! Have a great day!

Hi there!

[tex]\large\boxed{x < 2}[/tex]

[tex]\frac{4x + 6}{7} < 2[/tex]

Begin by multiplying both sides by 7:

[tex]4x + 6 < 2 * 7 \\\\4x + 6 < 14[/tex]

Subtract 6 from both sides to isolate for x:

[tex]4x + 6 - 6 < 14 - 6\\\\4x < 8[/tex]

Divide both sides by 4 to solve for x:

[tex]4x/4 < 8/4\\\\x < 2[/tex]

Answer:

perimeter is  34 cm

Step-by-step explanation:

Notice you need to find the value of two sides whose measure is not given. The first one is horizontal and 10 cm - 4 cm = 6 cm in length

The second one is vertical with a measure of 7 cm - 4 cm = 3 cm

Then, the addition of all sides going clockwise becomes:

7 + 10 + 4 + 6 + 3 + 4 = 34 cm

Answer:

(12x + 18)/(x+9)

Step-by-step explanation:

We have: (x + 11x + 18)/(x+9). First simplify this equation by adding like terms.

(12x + 18)/(x+9), which is your answer. This is the final answer because we can't simplify this expression anymore.

Hey there!

The answer is √20 or approximately 4.47

We can use the Pythagoreon Theorem, which is [tex]a^2 +b^2=c^2[/tex]. [tex]a[/tex] and [tex]b[/tex] are the names of the two sides, and [tex]c[/tex] is the name of the hypotenuse leg, or the longest side. We will plug the numbers into the formula, and solve:

[tex]2^2+4^2=c^2\\4+16=c^2\\20=c^2\\4.47...=c[/tex]

Have a terrifcly amazing day!

Answer:

n = 70

Step-by-step explanation:

n/10 + 8 = 15

n + 80 = 150

n = 150 - 80

n = 70

Answer:

n = 70

Step-by-step explanation:

1) Subtract  8 from both sides of the equation

n/10 + 8 - 8 = 15 - 8

2) Simplify

n/10 = 7

3) Multiply all terms by the same value to eliminate fraction denominators

10 · n/10 = 10 · 7

4) Simplify

n = 70

so your answer is n = 70. Hope that helps!

Answer:

Numerele întregi pozitive sunt toate numerele întregi mai mari decât zero: 1, 2, 3, 4, 5, .... Numere întregi negative sunt toate opusele acestor numere întregi: -1, -2, -3, -4, -5, .... Nu considerăm că zero este un număr pozitiv sau negativ. Pentru fiecare număr întreg pozitiv, există un număr întreg negativ, iar acești numere întregi se numesc opuse. De exemplu, -3 este opusul lui 3, -21 este opusul lui 21 și 8 este opusul lui -8. Dacă un număr întreg este mai mare decât zero, spunem că semnul său este pozitiv. Dacă un număr întreg este mai mic decât zero, spunem că semnul său este negativ.
