inysia [295]

Answer:

Step-by-step explanation:

45 - 25 = 20

65 - 45 = 20

as you can see the common difference between the 3 consecutive numbers 25 , 45 and 65 is a constant (20)

so ,we are in an arithmetic sequence case with :

first term 25

common difference r = 20

Let’s label the sequence: Un

then

Un = U1 + (n-1)×r

= 25 + (n-1)×20

= 20n + 5

for n = 10 → U10 = 20(10) + 5 = 200 + 5 = 205

Answer:

The answer for A is $7.85m^{2}$ .

The answer for B is 4 cans.

The answer of C is $98.

Step-by-step explanation:

A-

Multiply 2.5 by 3.5 and you'll get 8.75 Multiply 3.5 by 1.2 and you'll get 4.2; divide and your answer will be 2.1 Add to 8.75 Get 10.85 Subtract from area of door ( 3m because 1.5 times 2 is 3) and you'll get 7.85

B-

Divide 7.85 by 2.5 and you'll get 3.104; round that and you'll get 4 cans.

C-

Multiply the amount of cans (4) by 24.5. Do this and you'll get $98.

Solve x/3 = x+2/2. X=

Leni [432]

Answer:

I will assume that the term "x+2/2" is meant to be "(x + 2)/2)." Otherwise the equation would read (x/3) = x + 1

Step-by-step explanation:

(x/3) = (x + 2)/2

x = 3*(x+2)/2 [Multiply both sides by 3]

x = (3x + 6)/2

x = (3/2)x + 6/2

x - (3/2)x = 3

-0.5x = 3

x = -6

====================

Check:

Does (x/3) = (x + 2)/2 for x = -6?

(-6/3) = (-6 + 2)/2

-2 = -4/2

-2 = -2 YES

Find becky's mistake Choose 1

ss7ja [257]

Hi there!

mistake= step 2..

If you can see, the equation is the opposite so this means that to find the answer, your gonna have to add first.. instead of subtracting..

1.Add the terms:

$7+\frac{5}{4}=7\frac{5}{4}$

2.Simplifly the terms:

$7\frac{5}{4}=7\frac{25}{20}$

$\frac{4}{5}=\frac{16}{20}$

3.Subtract the terms:

$7\frac{25}{20}-\frac{16}{20}=7\frac{9}{20}$

Therefore, the mistake was step 2...
