okay so for the first one it's 3b-16
but when you see b=8 you would rewrite it as 3×8- 16 and once you do that you should have the answers you do the same thing for the rest of them :)
For example, for 3b - 16, you put 3(8) - 16 because they state that b = 8.

Look at the end number of computers, which is 40 right?
So with the total number of 40, you will simply subtract 10 and 5, to get the missing number.
Which is 40-10-5= 25
Then for printers you would do, 8-2= 6
Then by filling in the first blank you can move into the second blank by adding up all the three numbers you now have,
8+2+6= 16
Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
How fast did Car B travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Answers
Answer:
60mph
Step-by-step explanation:
2s - 30 = 1.5s
2s - 1.5s = 30
.5s = 30
s = 60 mph is car B's speed

Answer:
-2/3 + 1/3 = -1/3
Step-by-step explanation:
using addition to solve a fraction with the same base
step 1: take the denominator of both fractions and clear them from the equation
ex: -2/3 + 1/3 = ? (-2 + 1 = ?)
step 2: solve the new equation -2 + 1 to get your answer of
ex: -2 + 1 = ? (-2 + 1 = -1)
step 3: since both denominators of the fractions have the same number then our answer will also have a denominator of 3 giving us the answer to the problem -2/3 + 1/3 = ? is -1/3

A sequence in which the difference between all pairs of consecutive numbers is equal is called an arithmetic progression.
We have the following information available from the question is:
The first two numbers in a sequence are 3, 9.
We have to find the next 2 terms of the arithmetic sequence.
Now, According to the question:
The first two numbers in a sequence are 3, 9.

Find the 98th term of the arithmetic sequence 14, 10, 6,
Answers
y = -4x + 14
97 x -4 = -388
-388 + 14 = -374
The required 98th term of the arithmetic progression is -374.
What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values.
Here,
Given sequence,
14, 10, 6,
First term,
a = 14,
common difference d = 10 - 14 = -4
Explicit formula,
nth term = a + (n -1)d
98th term = 14 + (98 - 1)(-4)
98th term = 14 + 97 (-4)
98th term = -374
Thus, the required 98th term of the arithmetic progression is -374.

$16
$18
$20
$21
Answers
The price of the food on the menu will be set at $21.
Cost of food item = $6.78
Food cost percentage = 33%
Let the price on the menu be represented by x.
Therefore, based on the information given, the equation to solve the question will be:
= 33% × x = $6.78
33/100 × x = $6.78
0.33 × x = $6.78
0.33x = $6.78
x = $6.78/0.33
x = $20.54
x = $21 approximately
Therefore, the price of the food on the menu will be set at $21.

one number is 15 more than a second number.The sum of the number 115. What are the numbers?
Answers
The second number is 50
X= first number
Y= second number
X+Y= 115 > or 2y+15= 115 > subtract 15 from both side
2y= 100> divide by 2 on each side> y=50
There you have solved for y, now solve x
X= 50+15 > which is 65
So therefore, the first number is 65 and the second is 50.
