Sam is 4 years younger than Linda. The sum of their ages is 28. Find both Sam and Linda’s age and show your work.

Answers

Answer 1

Answer:

Sam = 6 years

Linda = 22 years

Step-by-step explanation:

this is best solved by using an algebraic equation

let Sam's age be x

let Linda's age be 4x

now that we defines our variables let's make an algebraic equation

the sum of their ages is 28 so

4x + x = 28

combine like terms

5x = 28

find for x

x = 28÷ 5 = 5.6 (don't approximate yet let's take the raw age)

Sam is 5.6 years

Linda is 4 years older so we multiply Sam's age by 4

4 × 5.6 = 22.4

Linda is 22.4 years

now let's round our answers to the nearest whole

5.6 ~ 6 years

22.4 ~ 22 years

let's double check and add our answers now

22 + 6 = 28

the answer is correct

What will be the graph of the circle (x-4)^2+(y+3)^2=16

Answers

Answer:

x + y - 5 = 0

Step-by-step explanation:

(x-4)² + (y+3)² = 16

To remove the square on the left side, we square root both sides

√(x-4)² + √(y+3)² = √16

The square will cancel the square root on the left side, while the square root of 16 is 4

(X-4) + (y+3) = 4

open the brackets

x-4+y+3=4

x + y = 4 + 4 - 3

x + y = 5

x + y - 5 = 0

Using ƒ(x) = 3x − 3 and g(x) = -x, find g(ƒ(x))
a. 3x+3
b. 3-3x
c.-3-3x
d. 2x-3

Answers

Answer:  Choice B.  3 - 3x

Work Shown:

[tex]g(x) = -x\\\\g(f(x)) = -f(x)\\\\g(f(x)) = -(3x-3)\\\\g(f(x)) = -3x+3\\\\g(f(x)) = \boldsymbol{3-3x}\\\\[/tex]

Explanation: We start with the outer function g(x). In the second step, we replace every copy of x with f(x). From there we plug in f(x) = 3x-3 and simplify using the distribution rule.

The notation [tex]g(f(x))[/tex] is the same as writing [tex](g \circ f)(x)[/tex]

Step-by-step explanation:

We can mark the blue cars as x, so now, we have 9:7, and 72:x, we can use cross multiplication to get the value of x, 72*7 = 9x, which we can simplify into 504 = 9x, and can divide both sides by 9 to get 56 = x.

Using the area model divide, true or false, 79/7 is equal to 11 R 1.

Answers

Area models are used to evaluate products and divisions

[tex]\mathbf{79 \div 7 = 11\ R\ 1}[/tex] is false

The division equation is given as:

[tex]\mathbf{79 \div 7 = 11\ R\ 1}[/tex]

Express 79 as 77 + 2

[tex]\mathbf{(77 + 2) \div 7 = 11\ R\ 1}[/tex]

Split the expression on the left-hand side

[tex]\mathbf{77 \div 7+ 2 \div 7 = 11\ R\ 1}[/tex]

Divide 77 by 7

[tex]\mathbf{11+ 2 \div 7 = 11\ R\ 1}[/tex]

2 divided by 7 is 0 with a remainder of 2

So, we have:

[tex]\mathbf{11\ R 2 = 11\ R\ 1}[/tex]

The equations above are not equal.

This is represented as:

[tex]\mathbf{11\ R 2 \ne 11\ R\ 1}[/tex]

Hence, [tex]\mathbf{79 \div 7 = 11\ R\ 1}[/tex] is false

Adnan drives 16.5 miles in 10 minutes. He passes a sign which gives the speed limit as 70 mph. By how much, in mph, did Adnan's average speed exceed the speed limit?​

Answers

Answer:  29 mph

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

Explanation:

10 minutes = 10/60 = 1/6 of an hour

Divide the distance over the time duration to find his speed

speed = distance/time

speed = (16.5 miles)/( 1/6 hr )

speed = 16.5*(6/1) mph

speed = 99 mph

Then subtract off the speed limit posted by the sign.

99 - 70 = 29 mph

Adnan is 29 mph over the speed limit.

Answer: 29 miles/hour (mph)

Step-by-step explanation:

10 minutes is 0.16667 hour (hr).

16.5 miles/0.16667 hr = 99 mph

99 - 70 = 29 mph
