the difference between 2 whole numbers is 66. the ratio of the 2 numbers is 2:5, what are the 2 numbers

shtirl [24]

Answer:

44 and 110

Step-by-step explanation:

The ratio of the 2 numbers = 2 : 5 = 2x : 5x ( x is a multiplier ) , thus

difference = 5x - 2x = 3x , then

3x = 66 ( divide both sides by 3 )

x = 22

Thus

2x = 2 × 22 = 44

5x = 5 × 22 = 110

The 2 numbers are 44 and 110

Evaluate the polynomial when a.x=0 and b.x=-1<br> x2 – 3x - 7

Arlecino [84]

Answer:

a) -7 & b) -6

Step-by-step explanation:

Here,

a) x = 0

Solution ↦

$x2 - 3x - 7 \\ = 0 \times 2 - 3 \times 0 - 7 \\ = - 7$

b) x = -1

Solution ↦

$x2 - 3x - 7 \\ = - 1 \times 2 - 3 \times ( - 1) - 7 \\ = - 2 + 3 - 7 \\ = - 9 + 3 \\ = - 6$
