The value of x in the expression 7x-3=5x+5 is 4
Given
7x-3=5x+5
Here,
The equation is linear in variable x .
7x-3=5x+5
7x - 5x - 3 = 5
2x-3=5
2x = 5 + 3
2x=8
x = 8/2
x=4
Thus the value of x is 4 .

a = 77, b = 118, c = 62
a = 36, b = 103, c = 77
a = 36, b = 118, c = 62
Answer:
The correct option is 4.
Step-by-step explanation:
If a transversal line intersect two parallel line, then the alternate interior angles are equal.
The value of a is 36.
The sum of two interior angle is equal to the exterior angle of third vertex.
The value of c is 62.
If two angles lie on a straight line, then they are supplementary angles and their sum is 180 degree.
The value of b is 118.
Therefore option 4 is correct.
Answer:
C
Step-by-step explanation:
The weight of the weight lighting bar = the initial value/y-intercept (b) = 45
Amount of weight = x
Total amount of weight = y
The rate of change (m) = 1
Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b
Thus:
y = (1)x + 45
y = x + 45
The correct option is c
Answer:
13 bracelets
Step-by-step explanation:
If you have 260 cm of string and you need 20 cm for each bracelet, you have to divide 260 by 20. Which gives you 13
Answer: Dorothea can make 13 bracelets.
Step-by-step explanation: If Dorothea has 260cm of strings, she should cut the string accordingly to set aside the strings. Cutting 260cm of 20cm length each would be the same as doing 260 divided by 20. If you do the math (mentally or using a calculator), you would get 13 pieces of strings, meaning Dorothea can make 13 bracelets. Hope this helped!
The distance from balloon to the western station is 495 miles.
Explanation:
The distance between two weather stations are 165 miles.
The angle of the regular triangle bearing from the western station is given by
90° - 40° = 50°
The angle of the regular triangle bearing from the eastern station is given by
90° + 22° = 112°
The angle of the balloon is given by
180° - 50° - 112° = 18°
Now, to find the distance of the balloon from the western station, let us use the law of sines formula,
Let us substitute the values.
Where and
Thus, we have,
Multiplying both sides of the equation by sin 112, we get,
Simplifying, we have,
Thus, the distance from balloon to the western station is 495 miles.
