Answer:
Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
Step-by-step explanation:
Like terms: and , and , and
Not like terms: and , and , and
Two or more terms are called like terms if they have same variables and powers.
and are like terms because they have same variable y with same power 2.
and are not like terms because they have same variable y with different powers.
and are like terms because they have same variables kt with same power 1.
and are like terms because both are constant.
and are not like terms because one have variable and other is constant.
and are not like terms because they have different variables.
N = 9
M = 87.11
According to the situation, the data provided and the solution are as follows
The scores for the student in the classroom is
= 88 88 92 88 88 72 96 88 84
The different student's number of scores is 9
The solution of new n and M is shown below:-
Sample size (n) = 9
Sample mean (m) is
=
= 87.11
There are 11 trains containing giraffes and 7 trains containing rabbits.
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of train with giraffes and y represent the number of train with rabbits.
Hence:
25x = 40y
25x - 40y = 0 (1)
Also:
25x + 40y > 500 (2)
From both equations:
A possible solution is x = 11, y = 7

if we will take the LCM
five will be common
34+41/5
75/5
15 is the answer
12.5
Step 1:
0.4 ( 3b + 10 ) = 19 Equation
Step 2:
1.2b + 4 = 19 Multiply
Step 3:
1.2b = 15 Subtract 4 on both sides
Step 4:
15 ÷ 1.2 Divide
b = 12.5
