Answer:
2239grams
Step-by-step explanation:
Answer:
27 degrees and 63 degrees
Step-by-step explanation:
Let n be the number.
Angle 1: 2n-15
Angle 2: 3n
If the angles are complementary they add up to 90.
Therefore we can write an equation.
2n-15+3n=90
Combine like terms
5n-15=90
Add 15 to both sides
5n=105
n=21
Now we plug 21 in for n and solve for the angles
Angle 1 = 2(21)-15
Angle 1 = 42-15
Angle 1 = 27
Angle 2 = 3(21)
Angle 2 = 63
Step-by-step explanation:
let
(-7,-8) =(x1, y1)
and (-6,7)=(x2, y2)
by the formula
d=√(y2-y1) ²+(x2-x1) ²
=√(7+8)²+(-6+7)²
=√15²+1²
= √225+1
= √226
Answer:
v=-60
Step-by-step explanation:
Answer: a) No Solution
b) Infinite Solutions (All Real Numbers)
<u>Step-by-step explanation:</u>
4(g + 8) = 7 + 4g
4g + 32 = 7 + 4g <em>distributed 4 into g + 8</em>
32 = 7 <em> subtracted 4g from both sides</em>
Since the statement is false because 32 ≠ 7, then there is NO SOLUTION
-4(-5h - 4) = 2(10h + 8)
20h + 16 = 20h + 16 <em>distributed</em>
16 = 16 <em>subtracted 20h from both sides</em>
Since the statement is true because 16 = 16, then there are INFINITE SOLUTIONS so x can be all real numbers.
