Answer:
x (children) = 58
y (students) = 66
z (adults) = 29
Step-by-step explanation:
Step 1: Write system of equations
x + y + z = 153
5x + 7y + 12z = 1100
1/2x = z
The best way to solve the systems of equations is to use an augmented matrix:
Top row: [1 1 1 | 153]
Middle row: [5 7 12 | 1100]
Bottom row: [1/2 0 -1 | 0]
And then put it in RREF form:
Top row: [1 0 0 | 58]
Middle row: [0 1 0 | 66]
Bottom row: [0 0 1 | 29]
Im p sure the degree is one
Answer:
The drawing will fit the index card
Step-by-step explanation:
The scale use by Shannon is
1 inch represent 0.5 feet.
Thus, the length of the car in the drawing is 12 * 0.5 = 6 inch.
The size of the paper is 5 inch by 7 inch
Hence, considering the longest side of paper representing the length of the car, it can be said that the drawing will fit the index card.
Answer:
C, A, B
Step-by-step explanation:
C=0.127
A=0.125
B=0.120
Answer:
a. 2
b. 6
c. 1
Step-by-step explanation:
The degree is the highest exponent on the variable in an expression
a. 2
b. 6
Both x and y have exponents of 3. To determine the degree, add the exponents together. 3+3=6
c. 1
When no exponent is present on the variable, it is always 1.
