Answer:
x = 7 and y = −2
(7, -2)
Step-by-step explanation:
x = 1 - 3y
3x + 3y = 15
Substitute −3y + 1 for x in 3x + 3y = 15:
3(1 - 3y) + 3y = 15
3 - 9y + 3y = 15
3 - 6y = 15
-3 -3
-6y = 12
/-6 /-6
y = -2
Now we solve for x. Substitute −2 for y in x = −3y + 1:
x = 1 - 3y
x = 1 + (-3)(-2)
x = 1 + 6
x = 7
Now we check our solution.
x = 1 - 3y
7 = 1 + (-3)(-2)
7 = 7 ✅
3x + 3y = 15
3(7) + 3(-2) = 15
21 - 6 = 15
15 = 15 ✅
Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
There were 16 total storms, meaning our denominator is 16. Since 8 grew into hurricanes, we can leave that alone. Since 5 out of 16 storms were major, 5 is our numerator.
5/16 storms were major because 8 were hurricanes and the other 3 were other kinds of storms. As a decimal conversion, about 31% of these storms were major.
How to find the percentage conversion:
Step 1: We take the fraction 5/16.
Step 2: Since our numerator is 5 and the default denominator is a maximum of 100, we can multiply 5 by 100.
5 x 100 = 500
Step 3: We can divide 100 by 16 to get our decimal conversion.
100 divided by 16 will give us 31.25, which also is representative of 31 and 1/4 added together.
Your final answer: With there being 16 storms, 5 of these storms are major (5/16). In terms of if there were 100 total storms, about 3/10 of these storms were major.
Answer: 7 x 2 x 2 x 2
Step-by-step explanation:
So 7x8 = 56; 7 is prime, but 8 can be factored further; 8 = 4x2, but the 4 can be factored; 2x2
So now you have the prime factorization of 56= 7 x 2 x 2 x 2
