Answer:

Use the distributive property to evaluate the expression 5(2x – 3) when x = 2. 5(2x ...

Step-by-step explanation:

answer:

x=10

step-by-step explanation:

let us solve your equation step-by-step

5+2x=25

step 1: simplify both sides of the equation

2x+5=25

step 2: subtract 5 from both sides

2x+5−5=25−5

2x=20

step 3: divide both sides by 29

2x/2=20/2

x=10

good luck :)

i hope this helps

brainliest would be highly appreciated

Answer:

27º

Step-by-step explanation:

complementary angle is equal to 90º

90 - 63 = 27

Answer:

26 is the hypotenuse

Step-by-step explanation:

a² + b² = c²

Given:

a = 24

b = 10

Work:

a² + b² = c²

24² + 10² = c²

576 + 100 = c²

c² = 676

[tex]\sqrt{c^2} =\sqrt{676}[/tex]

c = 26

Answer:

Solution given:

by using Pythagoras law

hypotenuse ²=perpendicular ²+base².

hypotenuse ²=10²+24²

hypotenuse=√676=26

so

hypotenuse=26

Answer:

x = 21, ∠ ABE = 55°

Step-by-step explanation:

∠ ABD is right and

∠ ABE + ∠ DBE = ∠ ABD , that is

3x - 8 + x + 14 = 90

4x + 6 = 90 ( subtract 6 from both sides )

4x = 84 ( divide both sides by 4 )

x = 21

Then

∠ ABE = 3x - 8 = 3(21) - 8 = 63 - 8 = 55°

Step-by-step explanation:

oh and also if your grades are bad just do to the dashboard page and highlight you grade percentedge and click inspect if you know and if you see you number pecent on the inspect and right click and click edit as htl and change it to any percent you want then just click out of the inspec option and you will have A S AND B S

The approximate length of the cylinder's radius will be 3.3 inches. Then the correct option is A.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.

Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.

Let x be the length of the radius. Then we have

x² = 6² - 5²

x² = 36 - 25

x² = 11

 x = √11

 x = 3.316

 x ≅ 3.3

Answer:

  D.  2%  

Step-by-step explanation:

The growth rate can be found by looking at the growth factor of the exponential function.

  f(x) = (initial value) × (growth factor)^x

The growth rate is related by ...

  growth factor = growth rate + 1

This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.

__

We can write the function g(x) describing the table as ...

  g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))

So, this could be ...

  g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x

     where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor

This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.

__

Then the difference between the growth rates of the two functions is ...

  4% - 2% = 2% . . . . . matches choice D

Answer:

W(4,3)

Step-by-step explanation:

how is that a square?

Answer:

Step-by-step explanation:

firstly ,

Given That

principal(p)=$2800

Rate(R)=4.25%

Time(T)=30 years

now , we have from formula

simple interest (S.I)=   P × T ×R / 100

    =   (2800×30×4.25)    /   100

    =  $3570  

Therefore , Simple Interest in 30 years will be $3570

now , we know

Amount(A) =  Principal (P) + Interest (I)

                 =    $2800 + $3570

                   = $ 6370

Therefore the simple interest in 30 years will be $3570 and the total amount in the bank will be $6370 .

Answer: 6.6 miles

Step-by-step explanation:

Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.

The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:

78% of x = 23.4

0.78 × x = 23.4

0.78x = 23.4

x = 23.4 / 0.78

x = 30 miles

Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:

= 30 - 23.4

= 6.6 miles

Answer:

Step-by-step explanation:

to find ∠QPS   we need the arc SQ  and RS   we will take  1/2(RS-QS) = QPS

find QS :

360 = RS + RQ + QS

360 = 150 + 110 + QS

100 = QS  

now plug into formula above

∠QPS = 1/2(150-100)

∠QPS = 1/2(50)

∠QPS = 25°
