Answer:
75 chairs
Step-by-step explanation:
1. 9x+3 : write equation
2. 7x+19 : write equation
3. 9x+3=7x+19 : make both equations equal to each other
4. 2x+3=19 : subtract 7x from both sides
5. 2x=16 : subtract 3 from both sides
6. 8 : divide 2 on both sides of the equal sign
7. 9(8)+3=75 : plug 8 into the equation
If there is 6 times as many blue cars as white cars, share it in the ratio 6:1.
6 + 1 = 7
35 ÷ 7 = 5
6 x 5 = 30
1 x 5 = 5
Answer: 30 blue cars and 5 white cars
Answer: 26
Step-by-step explanation: From the remainder theorem ,
If P (x) = 2x⁴ ⁻ x³ + 2x² ⁻ 6. is divided by ( x - 2 ).
It means that if P(x) is divided by (x - 2 ) and leaves a Remainder, it implies that x - 2 is not a factor of P(x) , but if it leaves no remainder, it means x-2 is a factor of P(x).
Therefore , to find the remainder, find the zero of x - 2, and substitutes for the value in P(x) to know the remainder
x - 2 = 0
x = 2
Now put this in P(x)
P(x) = 2(2)⁴ - (2)³ + 2(2)² - 6
= 2(16) -8 + 2(4) -6
= 32 -8 +8 -6
=26
Therefore the remainder when P(x) is divided by x -2
=26
Note: Since the division of P(x) by x - 2 leaves a remainder, it means that
x - 2 ≠ a factor of P(x)
