Answer:

b= 70

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to exterior angle.

a+b = 140

We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal

b+b = 140

2b =140

Divide by 2

2b/2 =140/2

b= 70

REY [17]

6 bags of dog food × $9 = 54
$89 total - $54 spent on dog food = $35 spent on cat food

$35 / $8 = 4.375, but you can't have decimals for cat food bags so round down.

= 4 bags of cat food

Recall that rational numbers are numbers that can be represented as the ratio, or fraction, of two integers. When expressed as d

Answer:

1) $\frac{5}{-14}$ =0.3571428571 2) Terminating

Step-by-step explanation:

1st. To answer this question let's divide with long division algorithm 5 and -14.

0.3571428571

-14)50

-70

100

-56

-112

100

-98

5 (dividend) : -14 (divisor) $\frac{5}{-14}$

Long division (check below)

With the same two numbers -14 and 5 we can write in a Long Division

5) -14

- 2.8

5) -14

So $\frac{-14}{5}=-2.8$

2nd. Both are terminating ones for they have finite quantities of numbers. -2.8 and 0.3571428571, as we can see that these are rational numbers for they can be written as a/b, and b≠ 0.

$\frac{5}{-14}$ form.

$\frac{-14}{5}$ form.
