What value(s) of z makes the equation 7/6 Z + 1/3 = -5 / 6 true; Z = -1, Z= 2, Z= 1, or Z= -36 / 63?
Answer:
Z = -1
Step-by-step explanation:
to find which value of Z makes the equation true substitute each value of Z into the equation.
Z = -1
7/6(-1) + 1/3 = -5/6
-5/6=-5/6
all other values of Z will not give u an equal statement

The scale of a square map indicates that each inch on the map
corresponds to 5 miles. Write an expression that describes the area of
land shown on the map. If the map is 8 inches on one side, what is the
area of land shown on the map?
Answer:
Area of land: 800 miles.
Step-by-step explanation:
Since the map is a square, you can assume that all 4 sides will equal 8 inches. (Giving you a perimeter of 32, and an area of 64.) Since each inch corresponds to 5 miles, you multiply 8 by 5 which equals 40.
Lines l and m are parallel and a and b are parallel. Find the measure of angle 10 if measure of angle 1 is 62.

Lazare is dividing 52.8 ounces of cereal equally into 9 bags. Which is the best way to estimate the amount of cereal in each bag?
If I'm not mistaken it's 5.9
Estimate amount of cereal in one bag is 5.867 ounces.
What are mathematical operations?Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Total quantity of cereal that Lazare has = 52.8 ounces.
And number of bags into which cereal equally divides = 9
To find the amount of cereal in each bag,
Use mathematical operations,
Since, total bags are 9 and amount of cereal is 52.8 ounces.
So, in one bag amount of cereal = 52.8 / 9 = 5.8666 = 5.867
In one bag there will be 5.867 ounces of cereal.

First you add 3x+x because they are like terms.
3x+x-7=10
Your New Simplified Equation:
4x-7=10
Now, you have to take out the -7 by adding a positive 7. Also you have to add +7 on the other side so add 7 to 10.
Your New Simplified Equation:
4x=17 Now, you divide both sides by 4.

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
What is the volume of the pyramid in cubic centimeters?
Answer:
volume = 13500 [tex]cm^{3}[/tex]
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid = [tex]\frac{lwh}{3}[/tex]
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume = [tex]\frac{30*30*45}{3}[/tex]
= [tex]\frac{40500}{3}[/tex]
= 13500
volume = 13500 [tex]cm^{3}[/tex]
The volume of the pyramid is 13500 [tex]cm^{3}[/tex].
The volume of the square-based pyramid is [tex]13500cm^3[/tex]
The volume of a pyramid is given by
[tex]V=\dfrac{Ah}{3}[/tex]
where
[tex]A=\text{area of the square base}\\h=\text{perpendicular height}[/tex]
The area of the square base, [tex]A[/tex], is calculated as follows
[tex]A=side^2\\=(30cm)^2\\=900cm^2[/tex]
substitute the value of [tex]A[/tex], and [tex]h[/tex] ([tex]45cm[/tex]) into the volume formula to calculate the pyramid's volume
[tex]V=\dfrac{Ah}{3}\\\\=\dfrac{900\times 45}{3}\\\\=13500cm^3[/tex]
Therefore, the volume of the pyramid is [tex]13500cm^3[/tex]

A first number is four more than seven time a second. The sum of the number is 92. Find the number.
Answer:
11
81
Step-by-step explanation:
x = 7y + 4
x + y = 92
Solve for x in the second equation
x = 92 - y
92 - y = x
Equate the 2 xs
92 - y = 7y + 4 Add y to both sides
92 = 7y+y + 4 Combine
92 = 8y + 4 Subtract 4 from both sides
88 = 8y Divide by 8
88/8 = y
y = 11
===========
x = 7y + 4
x = 77 +4
x = 81
