A safe-breaker is attempting to crack a safe with a 7-combination code. So far they have worked out that:

The first digit is double the third digit
The code is a palindrome (it reads the same if it is reversed)
The fourth number is 7
The third number is one less than the sixth number
The second number is 3 less than the fourth number

Can you advise the safe-breaker on the correct combination?

Answer: The answer for 9 is 50 miles per hour and the one who drove farthest is is ben because at 5 hours he drove already 250 miles. And for number 9 according to the table she is driving 15 miles per hour because on the bottom it always adds up by 15 miles.

Step-by-step explanation: So first to figure out 9 I used y2-y1/x2-x1 to figure out the rate of change and got 50 miles per hour and the point I used were (5,100) and (5,250). Then According to Ben's graph it shows that he drove 250 miles at 5 hours while sally was at 100 miles for 5 hours. So Ben drove the farthest. Then finally for number 9 I concluded that sally is driving 15 miles per hour because distance always adds up by 15 miles.

The measurement of the angle X is 60 degrees.

Angles L and X are the highest angles according to the diagram. They line up to have an angle of L = X = 60 degrees.

However, because the figures in a diagram could be oddly arranged, you shouldn't rely exclusively on it. A more effective strategy is to consider the letter combinations JKLMN and VWXYZ.

Observe how the third letters of JKLMN and VWXYZ, respectively, are L and X. This indicates that the letters are congruent angles and couple up (since the polygons are similar). Thus, this is a non-visual method of understanding how angle L = angle X = 60.

The solution to the linear equation given as 2.4 (x - 6) = 0.4 (x + 8) + 12 is  x = 14.8

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The linear equation is given as

2.4 (x - 6) = 0.4 (x + 8) + 12

Open the brackets

So, we have

2.4x - 14.4 = 0.4x + 3.2 + 12

Collect the like terms in the above expression

So, we have

2.4x - 0.4x = 14.4 + 3.2 + 12

Evaluate the like terms in the above expression

So, we have

2.0x = 29.6

Evaluate the quotient in the above expression

So, we have

x = 14.8

Answer: 1/6

Step-by-step explanation:

The table of the function y = (1/2)x + 3 is when (x = 4, y = 5), (x = 6, y = 6),

( x = 9, y = 15/2), ( x = 11, y = 17/3).

An expression represents that two different forms of numerical and variables are the same.

Given an expression y = (1/2)x + 3 we have to determine the range of this function corresponding to the domain { 4, 6, 9, 11 }.

For x = 4,

y = (1/2).4 + 3.

y = 2 + 3.

y = 5.

For x = 6,

y = (1/2).6 + 3.

y = 3 + 3.

y = 6.

For x = 9,

y = (1/2).9 + 3.

y = 9/2 + 3.

y = 15/2.

For x = 11,

The volume of a cuboid or box is the multiplication of length, width, and height by that expression the width of the given cuboid box is 10 inches.

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

The volume of cuboid = length × height × width.

Given that,

Height (H) = 9 inches.

The length is three inches more than the width.

So,

L = 3 + W

Now,

Volume of box = 1170 inches³

Now,

The volume of the cuboid is given as

V = L×W×H

1170 = (3 + W) × W×9

W² + 3W - 130 = 0

W² + 13W - 10W - 130 = 0

W(W + 13) - 10(W + 13) = 0

(W + 13)(W - 10) = 0

W = 10,-13 since the length can never be negative so 10 inches will be right.

Answer:

The answer is in the attached screenshot.

Step-by-step explanation:

and ... ? what do we need to do ?

I guess finding the number of quarters and dimes.

x = number of quarters

y = number of dimes

x + y = 185

x = 185 - y

0.25×x + 0.1×y = 26.75

after all, a quarter has a value of $0.25, and a dime of $0.10.

let's use the identity of the first equation in the second equation :

0.25×(185 - y) + 0.1×y = 26.75

to make is simpler to see let's multiply the whole thing by 100 :

25×(185 - y) + 10y = 2675

4625 - 25y + 10y = 2675

4625 - 15y = 2675

1950 = 15y

y = 130

x = 185 - y = 185 - 130 = 55

there are 55 quarters and 130 dimes in the bag.

f(x)=5x+8   g(x)=(x-8)/5

f(g(x))=?, 5((x-8)/5)+8

f(g(x))=x-8+8

f(g(x))=x

g(f(x))=5x+8-8/5

g(f(x))=5x/5
