The radius of Earth is 6378.1 km,
which is 2981.1 km longer than the radius of Mars.
The radius of Mars is 3397 km.
Try this suggested solution:
1. if 'Equation2'-'Equation1', then
(5x+4y)-(5x-y)=42-27; ⇒ 5y=15; ⇒ <u>y=3</u>.
2. if to substitute y=3 into the Equation1, it is possible to find 'x':
5x-3=27; ⇒ 5x=30; ⇒ <u>x=6</u>.
answer: (6;3)
Answer:
She could choose 30 different combinations of cake and drink
Step-by-step explanation:
A coffee shop sells 5 different types of cake and 6 different kind of drinks.
This means that:
For each type of cake, there are 6 different kind of drink.
At all, there are 5 different types of cake.
So
6*5 = 30
She could choose 30 different combinations of cake and drink
Looks like the larger triangle is equilateral (well, it must be, otherwise finding the area is impossible). That means the inradius is 6 and the outradius is 12, which is to say the altitudes (equal to the height, in this case) of this triangle have length 6 + 12 = 18.
In the smaller right triangle, the length of the missing leg is half the base of the larger triangle; call this length By the Pythagorean theorem,
Then the area of the larger triangle is
The answer is
Distribute the 3 first.
Then add and subtract like terms.
5x+11
