Answer: a = 65° b = 78° c = 37°
Steps:
(2x - 9) + (2x + 4) + x = 180°
5x - 5 = 180 °
5x = 185°
x = 37
(2x + 4)
2(37) + 4
74 + 4 = 78
(2x - 9)
2(37) - 9
74 - 9 = 65
Check:
65° + 78° + 37° = 180°
180° = 180°
Answer:
The distance between Lisa hand and rock is 88 inches.
<h3> Step-by-step explanation:</h3>
Consider the provided information. We need to find how far from Lisa's hand is the rock 8 seconds after it hits the surface. The rock's distance from the lake's surface changes at a rate of −2 inches per second. In 8 second the distance of rock and surface will be: Distance = 8×(2) = 16 inches below the surface of lake. We took positive 2 because distance can't be a negative number.
hope it helps you friend ☺️
Answer:
option A. |c| is the answer.
because sqrt of any number is always positive. that's why we add the modulas symbol around the interger.
Assume that the larger number is m and the smaller one is n.
the larger is 10 less than twice the smaller, this means that:
m = 2n-10
the sum of the two is 38, this means that:
m+n = 38
substitute by the first equation in the second one:
2n-10+n=38
3n=48
n= 16
substitute by n in the first equation:
m=2n-10=2(16)-10= 22
based on this,
the larger number is 22 while the smaller number is 16
Would it be one million? That's my best guess
