There are nine boxes in each pack. Garth bought 2 packs, all together containing 18 boxes. So 18÷2=9. Rico bought 4 packs, so 36 boxes divided by 4 equals 9. And so on. Your answer is 9 boxes = 1 pack.
Step-by-step explanation:
A. 2(10)-(-10)
20 -(-10) -------> (-)×(-) =(+)
20 + 10
30
B.29 + 1
30
Answer:
x = 14
Angle B = 121°
Angle C is 59°
Step-by-step explanation:
First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)
10x-19 = 7x+23 subtract 7x
3x-19 = 23 add 19
3x = 42 divide by 3
x = 14
Angle B is 10x-19, and if x=14, then its 10(14)-19
Angle B is 140-19
which is 121°
Angle B = 121°
Angle B and Angle C add up to 180°
121° + c = 180°
c = 180-121
Angle C is 59°
The value of OB based on the information given about the triangle is 3 units.
<h3>How to illustrate the information?</h3>
It should be noted that dilation is the process of enlarging or shrinking of an object.
In this case, the triangle is dilated. Therefore, the length of OB will be:
= 3/4 × 4 = 3 units.
Therefore, the correct option is B.
