Answer:
z = -4
Step-by-step explanation:
I'm going to assume you mean solve for z.
5z - 8 = -28
add 8 to both sides.
5z = -28 + 8
5z = -20
divide both sides by 5
z = -4
Answer: The answer would be −4.
First add eight to both sides.
5z−8+8=−28+8
5z=−20
Now divide both sides by five.
5z divided by five = -20 divided by 5.
z=−4

The slope of the given data in the table will be 25.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The formula to calculate the slope of the line will be given below:-
m = (y₂ - y₁) / (x₂ - x₁)
Given data is as below:-
Number of months Savings Principal
5 $125
6 $150
7 $175
8 $200
The slope will be calculated as below:-
m = (y₂ - y₁) / (x₂ - x₁)
m = ( 150 - 125 ) / 6 - 5 )
m = 25
Therefore, the slope of the given data in the table will be 25.

Since the triangles are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{ST}{MN}[/tex] = [tex]\frac{RS}{LM}[/tex] , substitute values
[tex]\frac{x}{4}[/tex] = [tex]\frac{4}{2}[/tex] ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
(7)
Since the prisms are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{x}{35}[/tex] = [tex]\frac{2}{10}[/tex] ( cross- multiply )
10x = 70 ( divide both sides by 10 )

An angle measures 86° less than the measure of its complementary angle. What is the measure of each angle?
[tex]x + (x - 86) = 90[/tex]
[tex]2x - 86 = 90[/tex]
Both sides plus 86
[tex]2x = 90 + 86[/tex]
[tex]2x = 176[/tex]
Divided both sides by 2
[tex]x = \frac{176}{2} \\ [/tex]
[tex]x = 88[/tex]
So the angles are :
[tex]88 \: \: \: \: \: and \: \: \: \: 2[/tex]
The measure of the two complementary angles are 88° and 2°.
What is a complementary angle?"When the sum of two angles is 90°, then the angles are known as complementary angles."
Let, the complementary angle of the mentioned angle is x.
Therefore, the angle is = (x - 86°)
Now, x + (x - 86°) = 90°
⇒ 2x - 86° = 90°
⇒ 2x = 176°
⇒ x = 88°
Therefore, the measured angle is 88°.
It's complementary angle is = (90° - 88°) = 2°.

The product of their ages in the future is 408:
(x + 15)(x + 22) = 408
x² + 37x + 330 = 408 Expanded
x² + 37x - 78 = 0 Subtracted 408 from both sides

During the summer, Tyler delivers packages and Miranda cares for animals on a farm. To show their earnings, Tyler makes a graph and Miranda makes a table. Which statement is true?
Answer:
When Miranda works 5 hours instead of 4, her pay goes up by
$56.00 - 44.80 = $11.20
That is, Miranda is paid $11.20 for each hour she works.
The slope of Tyler's graph indicates he is paid $9.00 for each hour he works. Miranda's pay per hour is $11.20 - 9.00 = $2.20 more than Tyler's.
Miranda earns $2.20 more per hour than Tyler

If h(x) = 5 + x and (x) = 5. which expression is equivalent to (k-1)(o)? (5+) 1 (5+) 5+ 5+ (5 + x)
(5+x)/x
K*H = 1/x(5+x) or (5+x)1/x which = (5+x)/x because (5+x)1/x = [(5+x)/1] * [1/x] and anything multiplied by one is equal to itself.
If h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are h(x) = 5 + x and k(x) = 5x
We have to find the expression which is equivalent to (koh)(x)
(koh)(x) = k(h(x))
=k(5+x)
Now we have to plug in 5+x in the function k(x)
k(5+x)=5(5+x)
=25+5x
Hence, if h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x

Suppose that the volume of water in the rain barrel
decreased by 4 5/8 gallons in four minutes. What will be
the change in the volume of water after one minute?
Answer:
Step-by-step explanation:
A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
The change in the volume of water in one minute is 1 5/32 gallons.
What is a unit rate?A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
4 5/8 gallons decrease in 4 minutes.
This can be written as:
4 5/8 gallons = 4 minutes
37/8 gallons = 4 minutes
Dividing both sides by 4 we get,
(37/8) / 4 = 4/4 minutes
37/(8x4) = 1 minute
37/32 = 1 minute
1 5/32 gallons = 1 minute
Thus the change in the volume of water in one minute is 1 5/32 gallons.
