Simplify the expression (2.5x − 5) − ((7x − 9.7)).
Answer:
−4.5x+4.7
Step-by-step explanation:
The value of the expression (2.5x − 5) − ((7x − 9.7) is 4.5x - 4.7.
In order for us to simplify the expression (2.5x − 5) − ((7x − 9.7)), we simply have to open the brackets and collect like terms. This will be:
= (2.5x − 5) − (7x − 9.7)
= 2.5x - 5 - 7x + 9.7
= 2.5x - 7x - 5 + 9.7
= -4.5x - 4.7
Therefore, the values will be 4.5x - 4.7.

What is the probability that the first lands on an odd number and the second lands on an even number?
Enter you answer, as a fraction in simplified form, in the box.
Answer:
1/2
Step-by-step explanation:
if both cubes are 6 sided. Then for the first one the probability is 3/6. second is also 3/6. but we are looking for the probability of this outcome. we can add all of the sides to get 12. then we have 3 even numbers and 3 odd numbers. which added together is 6. we bow have 6/12, which is 1/2 simplified
Holly works as a consultant who earns a weekly salary, plus an amount every hour she works. If her total earnings are represented by (y) for (x) total hours worked in the table below, how much does she earn per hour?
5:450
6:480
7:510
8:540
She earns a total of $30 per extra hour of her work.
What is direct variation?Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -
y = Kx
K = y/x
where -
{K} is scale factor.
Given is that Holly works as a consultant who earns a weekly salary, plus an amount every hour she works. If her total earnings are represented by (y) for (x) total hours worked in the table below -
Hours: 5 6 7 8
Amount : 450 480 510 540
We can write the unit rate as -
r = (480 - 450)/(6 - 5)
r = 30/1
r = 30
Therefore, she earns a total of $30 per extra hour of her work.

A 9 foot flagpole cast a shadow 6 feet long, and at the same time a nearby tree cast a shadow 14 feet long. What is x the hight of the tree.
The height of the nearby tree is 21 feet.
What is proportion?
Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole.
According to the problem,
Height of the flagpole = 9 feet
Length of the shadow = 6 feet
Length of the shadow cast by the tree = 14 feet
Let the height of the tree be x,
Since they cast aa shadow at the same time nearby, If we set up a proportion,
⇒ [tex]\frac{9}{6}[/tex] = [tex]\frac{x}{14}[/tex]
⇒ 6x = 126
⇒ x = [tex]\frac{126}{6}[/tex]
⇒ x = 21 feet
Hence, we can conclude, the height of the shadow is 21 feet.

Answer:
Its c. c = 50.
Step-by-step explanation:
First, we need to figure out what the equation equals.
7 + 7/7 + 7*7 - 7 = x
PEMDAS
Parentheses, exponents, division/fraction, addition, subtraction.
7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.
7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.
Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.
c is the only one who has a calculation of 50.
