It’s -1 they are subjecting by 2
The answer is 4 for both x and y
6 • 4 = 24
12 • 4 = 48
24 - 48 + 24 = 0
-24 + 24 = 0
-24 - (-24) = 0
Answer:
3 packages of plates, 2 packages of cups
Step-by-step explanation:
Find the multiples of 8 and 12, the lowest one they have in common will help with your answer.
8 : 8 16 24 32 40 48 56
12 : 12 24 36 48
The number that they both have (least) in common is 24.
For 8, it is the 3rd multiple and for 12 it would be the second
A highway runs east-west between two towns C and B that are 25 km apart. Town A lies 15 km directly north from C. A straight road is built from A to meet the highway at D which is equidistant from A and B. Find position of D on the highway.
find distance AB
Using Pythagorian
AB^2 = 15^2+ 25^2
then find Point M which is midpoint of AB
AM=MB= 1/2 (AB)
now take a look at the right triangle ABC
tan(
Answer:
Step-by-step explanation:
Use the formula Sum = (a + L)*n/2
The tricky part is n. That's the number of terms between 1 and 99 inclusive.
n = 99 -1 + 1 = 99
n = 99
a = 1
L = 99
Sum = (1 + 99)*99 / 2
Sum = (100)*99/2
Sum = 4950
