Answer:
[tex]z = - \frac{13}{7} [/tex]
Step-by-step explanation:
1) Add 3z to both sides.
[tex]4 z+ 5 + 3z = - 8[/tex]
2) Simplify 4z + 4 + 3z to 7z + 5.
[tex]7z + 5 = - 8[/tex]
3) Subtract 5 from both sides.
[tex]7z = - 8 - 5[/tex]
4) Simplify -8-5 to -13.
[tex]7z = - 13[/tex]
5) Divide both sides by 7.
[tex]z = - \frac{13}{7} [/tex]
Therefore, the answer is z = - 13/7.

The sum of two numbers is 48.if the smaller number is subtracted from the larger the difference is 12 find the number
Answer:
18
Step-by-step explanation:
30 + 18 = 48
30 - 18 = 12
Both true, so our solution is correct.
The value of the larger number is 30 and the value of the smaller number is 18.
What is a number system?A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,
x + y = 48
x - y = 12
________
2x = 60
x = 30
y = 30 - 12
y = 18
Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

What is the Greatest Common Denominator or factor between 244 & 48
Answer:
GCF = 4.
Step-by-step explanation:
Find the prime factors:
48 = 2*2*2*2*3
244 = 2*2*61
The greatest common factor, the GCF) (picking out the common values) =
2 *2 = 4.
A really clever way of finding the GCF of 2 numbers is Euclid's algorithm. It can be used for very large numbers where it would be time consuming and/or rather difficult to find prime factors:
Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.
Replace a with b, replace b with R and repeat the division.
Repeat step 2 until R=0.
When R=0, the divisor, b, in the last equation is the greatest common factor.
So applying this to our problem:
244 / 48 = 5 remainder 4
Replacing a (244) with 48 and b (48) with R (4):-
48/4 = 12 remainder 0.
So the GCF is 4.

A pet store sold 2 birds. They sold 6 times as many turtles as they sold birds. How many turtles did they sell?
Answer:
12
Step-by-step explanation:
"6 times as many birds..." in other words 6 x 2
The number of turtles that was sold by the pet store given the number of birds sold is 12.
How many turtles are sold?
Multiplication is a mathematical operation that involves determining the product of two or more numbers. The sign used to represent multiplication is x.
Number of turtles were sold = 2 x 6 = 12

(x+y)² + 2(x+ y)(x- y) + (x– y)²
Answer:
2x(x+y)(x-y)
Step-by-step explanation:
Given the expression;
(x+y)² + 2(x+ y)(x- y) + (x– y)²
Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]
= (x+y)(x-y)(x+y+(x-y))
= (x+y)(x-y)(x+y+x-y)
= (x+y)(x-y)(2x)
hence the expanded form is 2x(x+y)(x-y)

ITS SO CONFUSINGNSKDN
Answer:
y=67.7 Degrees
Step-by-step explanation:
You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:
Tan(y)= 100/41
We then inverse tan to isolate y
y=tan^-1 100/41
y=67.7 Degrees
Note: Use a calculate to find the final answer

P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7. A. 0.125 B. 1 C. 7 D. 8
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8

Find the Perimeter & Area for the following circle.
use 3.14 for Pi
Round to the tenths place
Answer:
A = 28.3 cubic inches; P = 20.1 inches
Step-by-step explanation:
Looks like 3/4 of a full circle
The area of a circle is calculated with the formula: [tex]\pi r^{2}[/tex]
Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.
The radius is given as 3 inches
Area = [tex]3.14*3^{2} = 3.14*9 = 28.26[/tex] cubic inches = 28.3 cubic inches
------------------------
Perimeter is calculated with [tex]2\pi r[/tex].
But this is 3/4 of a circle with an additional two 3-inch sides
Perimeter = [tex]\frac{3}{4}*2\pi r[/tex] + 2(3) = 14.1 + 6 = 20.1 inches
