Evaluate each expression if w=2, x=3, y=5, and z=6. 3+4z

Mathematics
1 answer:
SashulF [63]4 years ago
3 0

Answer:

27

Step-by-step explanation:

The expression is 3 + 4z

First, you must know what the value of the variable "z" is.

Because the problem already tells you that z = 6, all you have to do is substitute z with 4:

3 + 4z = 3 + 4(6)

Next, solve using the Order of Operations (P.E.M.D.A.S.).

According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:

3 + 4(6) = 3 + 24 = <u>27</u>

The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine tha
stiks02 [169]

Answer:

Step-by-step explanation:

The Jones family has saved a maximum of $750 for their family vacation to the beach. It means that whatever they would do during the vacation, they cannot spend more than $750.

The inequality can be used to determine the number of nights the Jones family could spend at the hotel is

750 ≥ 75 + 125h

This can also be written as

75 + 125h ≤ 750

We would solve the inequality for the value of h.

125h ≤ 750 - 75

125h ≤ 675

h ≤ 675/125

h ≤ 5.4

For any value of h greater than 5.4 hours, the inequality will not be true.

What is the value of y?
hjlf
Start with the lower triangle.
It has a right angle and a 45-deg angle.
The third angle is also a 45-deg angle.
The lower triangle is a 45-45-90 triangle.
In a 45-45-90 triangle, the legs are congruent.
The hypotenuse is sqrt(2) times the length of either leg.
The legs are the hypotenuse divided by sqrt(2)
Since the hypotenuse of the lower triangle is 2sqrt(2),
the legs are 2sqrt(2)/sqrt(2) = 2.
Both legs measure 2.

One leg of the lower triangle is the shorter leg of the upper triangle.
The upper triangle is a 30-60-90 triangle.
The longer leg of a 30-60-90 triangle is sqrt(3) times the length
of the shorter leg.
Since the shorter leg measures 2, the longer leg measures 2sqrt(3).

y = 2sqrt(3)

Clyde is putting a fence around a rose bush in his garden . The measures of two sides that meet at a corner are 27 feet and 34 f
Nonamiya [84]

Answer:

The  length of the diagonal have to be 43.4 feet

Step-by-step explanation:

we know that

For the corner to be a right angle, the length of the diagonal must satisfy the Pythagorean Theorem

Let

x ----> the  length of the diagonal

so

x^2=27^2+34^2

x^2=1,885\\x=43.4\ ft

therefore

The  length of the diagonal have to be 43.4 feet
