Step-by-step explanation:
[tex]\angle A\cong\angle B\qquad\text{therefore}\qquad AC\cong BC\Rightarrow|AC|=|BC|\\\\\text{We have}\ |AC|=20;\ BC=3x-7.\\\\\text{Therefore}\\\\3x-7=20\qquad|\text{add 7 to both sides}\3x-7+7=20+7\\\\3x=27\qquad|\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{27}{3}\\\\x=9[/tex]

Anyone can find “v” and “u”??
Answers
Answer:
[tex]v = \frac{16}{3} \: \: and \: \: u = \frac{20}{3} [/tex]
Step-by-step explanation:
In triangle WYZ ,
[tex] {u}^{2} = {4}^{2} + {v}^{2} = 16 + {v}^{2} [/tex]
In traingle WXZ ,
[tex] {(3 + v)}^{2} = {5}^{2} + {u}^{2} [/tex]
Putting the value of U^2 in above eqn.
[tex] = > {(3 + v)}^{2} = 25 + (16 + {v}^{2} )[/tex]
[tex] = > {v}^{2} + 6v + 9 = 41 + {v}^{2} [/tex]
[tex] = > {v}^{2} - {v}^{2} + 6v = 41 - 9[/tex]
[tex] = > 6v = 32[/tex]
[tex] = > v = \frac{32}{6} = \frac{16}{3} [/tex]
Putting the value of V in eqn. below :-
[tex] {u}^{2} = 16 + { (\frac{16}{3} )}^{2} [/tex]
[tex] = > {u}^{2} = \frac{256}{9} + 16[/tex]
[tex] = > {u}^{2} = \frac{256 + 144}{9} = \frac{400}{9} [/tex]
[tex] = > u = \sqrt{ \frac{400}{9} } = \frac{20}{3} [/tex]

How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, then answer the question. *
Answers
Answer:
14 groups
Step-by-step explanation:
Given
[tex]Groupings = \frac{1}{2}\ day[/tex]
[tex]Duration = 1\ week[/tex]
Required
Determine the number of group in the week
To do this, we simply divide the duration by the number half day group.
This gives:
[tex]Group = \frac{Duration}{Groupings}[/tex]
[tex]Group = \frac{1\ week}{1/2\ days}[/tex]
Convert week to days
[tex]Group = \frac{7\ days}{1/2\ days}[/tex]
[tex]Group = \frac{7}{1/2}[/tex]
[tex]Group = 7 / \frac{1}{2}[/tex]
Convert to multiplication
[tex]Group = 7 * \frac{2}{1}[/tex]
[tex]Group = \frac{14}{1}[/tex]
[tex]Group = 14[/tex]
Hence, there are 14 groups
3x-4 or = to 7
plz help
Answers
Answer:
3 + 4 = 7 which is true.
Step-by-step explanation:
Whenever you have an equation with a plain variable (that is, no exponent included), there is only one number that will work when substituted for x.
To solve it, you have to "undo" what is done to the variable. You also go in the reverse order of operations, so you do the addition/subtract first, then multiplication/division.
You also have to do the same to both sides, kind of like keeping a balance scale in balance.
In this case, we subtract 4 from both sides first:
3x + 4 -4 = 7 - 4
The + 4 - 4 cancel each other out, so you get:
3x = 3
3x means "3 times x" so you divide by 3 to undo it. I will use the / to indicate division:
3x / 3 = 3 /3
so 1x = 1.
Since 1x is "1 times x" it is the same as x by itself, so:
x=1
AND, if we substitute 1 back into the original equation (the asterisk stands for multiply):
3 * 1 + 4 = 7
3 * 1 is 3, so:
3 + 4 = 7 which is true.
1 is the only number that works.
Hope this helped.

Write an equivalent expression to (-0.25x - 3) - (2.5x + 1.7) using the fewest possible terms.
Answers
Answer: -2.75*x - 4.7
Step-by-step explanation:
In the equation we have only one variable, this means that the minimum possible number of terms will be two, one term with x, and one term without x.
We can start with the equation:
(-0.25x - 3) - (2.5x + 1.7)
Now, let's rewrite this as:
-0.25x - 3 - 2.5x - 1.7
(-0.25*x - 2.5*x) + (-3 - 1.7)
Solving the parentheses we get:
-2.75*x - 4.7
That is the equivalent expression that has the fewest possible terms
