Answer:

x=12

Step-by-step explanation:

25 x 4 = 6x + 28

100 = 6x + 28

subtract 28 from each side

72 = 6x

divide each side by 6

12 = x

x = 12

Answer:

d. 80

Step-by-step explanation:

Similarity ratio of ABCD to EFGH = 4:3.

This implies that the ratio of AD to EH = 4:3

If EH = 60, then:

AD:60 = 4:3

AD/60 = 4/3

Multiply both sides by 60

AD = ⁴/3 × 60

AD = 80

Answer:

60 divided by 8

Step-by-step explanation:

60 divided by 8

Answer:

First evening: 8 phone calls

Second evening: 60 phone calls

Third evening: 15 phone calls

Step-by-step explanation:

third evening: x

second evening: 4x

first evening: x - 7

x + 4x + x - 7 = 83

6x = 90

x = 15

First evening: x - 7 = 15 - 7 = 8

Second evening: 4x = 4(15) = 60

Third evening: x = 15

Answer:

c(t)=115(1.04)^t

Step-by-step explanation:

algebraic rule to determine the cost, c(t), of the shoes after t years is:

c(t)=115(1.04)^t

inflation means a current dollar buy less in the future. example the price of shoes next two years will be :

115(1.04)^2=124.384 dollars

An algebraic rule to determine the cost, c(t), of the shoes after t years is [tex]c(t)=115(1.04)^t[/tex].

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, a pair of athletic shoes costs $115.

The inflation rate remains constant at 4%.

Let the cost, c(t), of the shoes after t years.

So, the function is [tex]c(t)=115(1.04)^t[/tex]

Therefore, an algebraic rule to determine the cost, c(t), of the shoes after t years is [tex]c(t)=115(1.04)^t[/tex].

Answer:

Jordan made mistake in his first step while multiplying.

Step-by-step explanation:

Given expression of Jordan's work is

14(8+4x) = 6x-(5-11x)

In the first step, Jordan multiplied the numbers to remove the braces.

He multiplied 14(8+4x) wrong as 14*8 is 112 rather than 126and on the right hand side, he did not change the sign of 11x to positive as two negatives are positive when multiplied.

Hence,

Jordan made mistake in his first step while multiplying.

Answer:

x = 14

Step-by-step explanation:

As we can see that the bottom side is equivalent to 3 of the smallest triangle and the side of the larger triangle is equivalent to the 9

This represents that it is dilated by 3 factor

So

= 3 × 3

= 9

Now the other side i.e. 5 of the smallest triangle also need to be dilated by a 3 factor

So the new side is 15

Also the largest triangle is x + 1

So,

15 = x + 1

x = 14

Answer: 1/40

Step-by-step explanation:

The equivalent value of the fraction is A = 1/40

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = p/q

when the value of p = 1/8

And , when the value of q = 5

On simplifying the equation , we get

A = ( 1/8 ) / 5

So , the left hand side of the equation is equated to the right hand side by the value of ( 1/8 ) / 5

A = ( 1/8 ) / 5

A = ( 1/8 ) ( 1/5 )

On simplifying , we get

A = 1/40

A = 0.025

Therefore , the value of A = 1/40 = 0.025

Hence , the fraction is A = 1/40
