What value of X makes the equation true -7x - (-5-x) = -9(2x-1) -1
Answer:
x = 1/4
Step-by-step explanation:
-7x - (-5-x) = -9(2x-1) -1
-7x + 5 + x = -18x + 9 - 1
combine like terms:
-6x + 5 = -18x + 8
add 18x to each side of the equation:
12x + 5 = 8
subtract 5 from each side:
12x = 3
divide both sides by 12:
x = 3/12 = 1/4

Here is the third problem:)
Answer:
15.0
Step-by-step explanation:
we are finidng the adjacent angle, they have given us the opposite and the missing adjacent side so we use tan
tan25=7/x
since x is at the bottom then switch
x= 7/tan25
x= 15. 012
Answer:
x = 15.01
Step-by-step explanation:
Given degrees 25
Since x is between the right angle and 25, x is adjacent
7 being the other shortest side would be the opposite
Given adjacent and opposite, you can use tangent
Tangent = opposite/adjacent
Tan(25) = 7/x
0.4663076582 = 7/x
x = 7/0.4663076582 (use calculator)
Solution: x = 15.0115484421

Answer:
The Legs of a right triangle are the two sides of a right triangle that intersect to form the right angle
Step-by-step explanation:
Right Angle Triangle-Two legs plus a hypotenuse make up a right triangle. The hypotenuse is the longest side of the right triangle and the side opposite the right angle, and the two legs meet at a 90° angle. Right triangles come in a variety of shapes, including 45°-45° right triangles and 30°-60° right triangles.

Amanda is 160 cm tall. She is 10 cm taller than her younger sister Carl a. Which of the following equations can be used to find x? X + 10 = 160 X + 160 = 10 X - 10 = 160 x = 10 + 160
Answer:
A. x + 10 = 160
Step-by-step explanation:
This is the correct choice since, we already know the height of Amanda and it gives us the difference between her sister and her height. We can formulate an expression.
x + 10 = 160
Solve.
160 - 10 = 150
x = 150
Thus, Carla is 150 centimeters tall.

Answer:
See below for answers and explanations
Step-by-step explanation:
1) Substitute d=100 into the equation and solve for s:
s=sqrt(9.81d)
s=sqrt(9.81(100))
s=sqrt(981)
s≈31.32
Therefore, the speed of the wave will be about 31.3 m/s
2) Substitute d=1000 into the equation and solve for s:
s=sqrt(9.81d)
s=sqrt(9.81(1000))
s=sqrt(9810)
s≈99.05
Therefore, the speed of the wave will be about 99 m/s

Evaluate the following:
a) A tea manufacturing company produces normal and green tea bags only. If 52.8% of 36850 total
production is normal tea bags, how many green tea bags are there?
b) If 61.6% of students out of 9855 total students are based in England, how many students are
based in England?
Answer:
A. Ans: Given,
Solution,
A tea manufacturing company produces normal and green tea bags only.
52.8% of 36850 production is normal tea bags.
Now,
Number of green tea bags=52.8% of 36850
=52.8/100×36850
=19456.8
Therefore, Number of normal tea bags=19456.8
The number of green tea bags is 17384
The number of students is 3071
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
a )
Total production of tea bags = 36850
Percentage of normal tea bags = 52.8 %
Total production of normal tea bags =
Percentage of normal tea bags x Total production
Total production of normal tea bags = ( 52.8 / 100 ) x 36850
= 19465.8 tea bags
Therefore , total amount of green tea bags = Total tea bags - Total normal tea bags
= 36850 - 19465.8
= 17384.2
≈≈ 17384
Hence , Total amount of green tea bags = 17384.2
b )
Total number of students = 9855
Percentage of students based in England = 61.6 %
Number of students based in England = Percentage of students x Total number of students
Number of students based in England = ( 61.6 / 100 ) x 9855
= 6070.68
≈ 6071
Hence , total number of students based in England = 6070.68
