Answer:

x = 3

Step-by-step explanation:

4x - 5 = 2x + 1

Subtract 2x from both sides;

2x - 5 = 1

Add 5 to both sides;

2x = 6

Divide both sides by 2;

x = 3

Sage is 7 years older than Jonathan. If Jonathan is x years old, how old was Sage 10 years ago?
Natalija [7]

Answer:

(x-3) years

Step-by-step explanation:

We are given that

Age of Jonathan= x years

Sage is 7 years older than Jonathan

It means

Age of Sage=(x+7) years

We have to find the age of Sage 10 years ago.

10 Years ago,

Age of Jonathan=(x-10) years

Age of Sage=(x+7-10) years

Age of Sage=(x-3) years

Hence, 10 years ago, age of Sage =(x-3) years

Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?<br> Help
Alisiya [41]

Answer:

h(4) = 0

Step-by-step explanation:

Hoping its ' kx '

h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k

Now we have k = -2. We will find h(4).

h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0

A rectangular prism has a length of 5/2 ft, width of 9/6 ft, and height of 2/3 ft. what is its volume?
ivanzaharov [21]
The formula of the volume of the rectangular prism:

V = length × width × height

We have:
l=\dfrac{5}{2}ft\\\\w=\dfrac{9}{6}ft\\\\h=\dfrac{2}{3}ft\\\\V=l\cdot w\cdot h=\dfrac{5}{2}\cdot\dfrac{9}{6}\cdot\dfrac{2}{3}\\\\=\dfrac{5}{2}\cdot\dfrac{1}{1}\cdot\dfrac{1}{1}=\dfrac{5}{2}=2.5ft.^3

Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk h
Anon25 [30]

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Carson walked her dog 1 13/20 more miles than Claire did.

Sorry for the lazy explanations Imao
