Answer:
x = 20 and y = 35
Step-by-step explanation:
So let's say that the two numbers are represented by x and y.
Firstly, the sum of the two is 55, so:
x + y = 55
Secondly, twice the lesser number is 5 more than the greater number, so, assuming x is lesser:
2x = y + 5
Let's isolate y in the second equation:
y = 2x - 5
We can substitute this into the first equation:
x + (2x - 5) = 55
Now we solve for x:
3x - 5 = 55
3x = 60
x = 20
Now that we know what x is, let's substitute that into the first equation and solve for y:
(20) + y = 55
y = 35
Therefore, x = 20 and y = 35
Hope this helps!

This helicopter has a rotor that moves at a rate of 600 spins per minute while flying. Which statement is supported by this information
Answer: d. The helicopter rotor will spin 36,000 times in 1 hour
Step-by-step explanation:
Option A is wrong because in 40 minutes the rotor will spin:
= 40 * 600
= 24,000 times
Option B is wrong because we cannot know the number of times the rotor will spin before being lifted off of the ground with the details given.
Option C is wrong because in 3 hours the rotor will spin:
= 600 * 3 * 60 minutes
= 108,000 times
Option D is correct because in 1 hour the rotor will spin:
= 600 * 1 * 60 mins
= 36,000 times

Answer:
C. 21.25 ( i'm assuming that C. says 21.25)
Step-by-step explanation:
Since it's an isosceles triangle, the two bottom angles are equal to one another. So 180 - 75 = 105. 105 ÷ 2 = 52.5
2x + 10 = 52.5
2x = 42.5
x = 21.25
Answer:
x=21.25
Step-by-step explanation:
triangle = 180 degree angle
knowns:
75 degrees and two opposing sides with same length have same angles
so:
180-75= 105
2(2x+10)=105
4x+20=105
4x=105-20
4x=85
x=85/4
x=21.25

Find the side AB using the law of sines with the one of the sides 11 and the angles 82 and 44 degrees
Answer:
7.7
Step-by-step explanation: We are trying to find side c or side AB
Using the law of sines formula,
a/sin a= b/sin b c/sin c we can solve for missing side.
We are given side BC or side a which is 11
We also are given angle A is 82 degrees
Angle C is 44 degrees also.
So let set up a proportion.
11/sin 82= x/sin 44
11/sin 82× sin 44=x
x= 7.7

The length of a rectangle is 5 inches less than 4 times the width. The perimeter is 110 inches. Find the length and the width.
Answer:
Length = 43 inchesWidth = 12 inchesStep-by-step explanation:
Perimeter of a rectangle = 2 * ( L + W)
The length of a rectangle is 5 inches less than 4 times the width.
Assume the width is x. Length is:
4x - 5
Equation is therefore:
2 * (4x - 5 + x) = 110
4x - 5 + x = 110/2
5x - 5 = 55
5x = 55 + 5
x = 60/5
x = 12 inches
If width is 12 inches, then length is:
= 4x - 5
= 4 * 12 -5
= 43 inches
Graph y<1−3x. I really need help on this question.
Answer:
You are correct, the answer that you highlighted
Step-by-step explanation:
We know y is LESS than the expression, therefore the shaded area would be at the bottom. Furthermore, the expression tells us simply that y is LESS than 1-3x, NOT EQUAL. Therefore, the graph must have a dotted line.
