Step-by-step explanation:

let smaller be x

larger number is x+5

4x-3(x+5)=29

4x-3x-15=29

x=29+15=44

x=44

larger number is 49

Answer:

C

Step-by-step explanation:

98

98 because 16 x 3 is 48 x 2 is 98

Answer:

1). x = 14

2). y = 2.4 cm

Step-by-step explanation:

In the diagram ΔNPQ ~ ΔNLM and NL = 3,

1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]

   (3x + 18)° = 60°

   3x = 60 - 18

   x = 14

2). Since, both the triangles are similar, corresponding sides will be proportional.

   [tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]

   [tex]\frac{y}{3}=\frac{3.2}{4}[/tex]

   y [tex]=\frac{3.2\times 3}{4}[/tex]

   y = 2.4 cm

Answer:

You have to use ur ruler so u can see what the longest side is, So basically use the ruler and look up the centimetre mark and then it shows you what number is at and whatever the biggest number is is what the longest side is.

Hey there!

- Factor pair basically 2 factors that you multiply the given numbers to each other to get a given product (answer)

“Factors of 72”

- So we have to find MULTIPLES that gives you 72

Answers ⬇️

▸ 1 • 72 = 72

(SAME thing with 72 • 1 = 72)

▸ 2 • 36 = 72

(SAME with 36 • 2 = 72)

Step-by-step explanation:

Answer:

y = 12 [tex](2.9)^{x}[/tex]

Step-by-step explanation:

The standard form of the exponential function is

y = a [tex](b)^{x}[/tex]

Find a and b by substituting ordered pairs from the table into the equation

Using (0, 12 ), then

12 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so

a = 12, then

y = 12 [tex]b^{x}[/tex]

Using (1, 34.8 ) , then

34.8 = 12 [tex]b^{1}[/tex] ( divide both sides by 12 )

b = 2.9

Thus exponential function is

y = 12 [tex](2.9)^{x}[/tex]

Answer:

24 miles per gallon

Step-by-step explanation:

Take the numbers of miles and divide by the number of gallons

96 miles / 4 gallons

24 miles per gallon

Answer: Darren is getting 24 miles per gallon. That should be your unit rate.

Answer:

16

Step-by-step explanation:

Given

u = x₁i + y₁j and v = x₂i + y₂j , then

u • v = x₁x₂ + y₁y₂

Given

u = - 4i + 8j and v = - 2i + j , then

u • v = ( - 4 × - 2) + (8 × 1) = 8 + 8 = 16

IT'S 20 FEET JUST FOUND OUT

Step-by-step explanation:

Answer:

$766.28

Step-by-step explanation:

The equation for interest rate is as follows:

[tex]A = P(1 + r)^t\\[/tex]

A = The total amount

P = Initial amount

R = The interest rate

T = Time

Let's plug everything into the equation that is given in the question:

The initial amount = 612

Interest rate = 2.85

Time = 8 years

[tex]A = 612(1+.0285)^8[/tex]

***Just a reminder we move the decimal over twice when working with percents***

Now, lets solve for the total amount:

[tex]A = 612(1.0285)^8\\A = 612(1.252086602)\\A = 766.28[/tex]

Therefore, after 8 years the principal is $766.28.

Answer:

π meters

Step-by-step explanation:

The diameter is 2  meters. Then the radius is 1 meter. So:

A=πr²

  =π(1)²

  =π meters ...............

Answer:

3.14

Step-by-step explanation

the formula of a circle is A=πrxr

2 divided by 2 is 1

1 x 1 = 1

3.14 x 1 = 3.14

thats is!

Answer:

10 percent

Step-by-step explanation:

40000 is the old value and 44000 is the new value. In this case we have a positive change (increase) of 10 percent because the new value is greater than the old value.

Answer:

see explanation

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is between the limits

difference of 2 sides < x < sum of 2 sides, that is

7 - 5 < x < 7 + 5 , then

2 < x < 12

Choose any 2 values between 2 and 12 as third side, so

third side could be 6 or 9 for example

Answer:

-3x - 18

Step-by-step explanation:

Use the distributive property.

-3(x + 6) = (-3)(x) + (-3)(6) = -3x - 18

Answer:

-3x-18

Step-by-step explanation:

Use the distributive property to simplify

-3(x+6)

(-3*x)+(-3*6)

-3x+(-18)

-3x-18

Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

Answer:

Step-by-step explanation:
