Answer:
The number of yellow sweets is 28
Step-by-step explanation:
Ratio of red to yellow sweets is 3:7
Total sweet is 40
total ratio is 3 + 7 = 10
To know the total number of yellow sweet, we have
(7/10) × 40
= 0.7 × 40
= 28
Answer: 64
Step-by-step explanation:
u = 56 * 8 / 7 = 64
Answer:
x = -7
Step-by-step explanation:
-x = 7 (Move variables to one side, already done in this case.)
(Divide both sides by -1. Do this to get the x by itself.)
x = -7 (Final Answer)

Answer:
The augmented matrix is of two equations, and two variables.
Step-by-step explanation:
This is an augmented matrix, which means the constant terms are on the last column.
The matrix can be written as
X1 + kX2 = 3
-5X1 + 6X2 = 1
The constants are 3, 1, and all the coefficients of the variables, X1 and X2.
X1 and X2 can take any values.
k is constant, just like 1, -5, and 6.
Though, it is not specified, the consistency or inconsistency of the equation depends on the value k takes.
The options 2 and 4 would have the same graphical representation.
Step-by-step explanation:
Step 1:
To determine which functions are equal to the question, we must assign values to x and see which values equal the function f(x) = .
Any random value can be assigned to x but the same value of x must be assigned to all the equations.
Step 2:
If we substitute x = 5, we get
Question; f(x) =
Option 1; f(x)
Option 2; f(x) =
Option 3; f(x) =
Option 4; f(x)
So options 2 and 4 would have the same graphical representation.
