Answer:

X=35°

Y=70°

Z=110°

I think this ans may help you

Answer and Step-by-step explanation:

We know that the lines are parallel. So,

x is equal to 70° because of vertical angles theorem.

y is equal to 70° because of interior angles theorem.

2z = y

2z = 70

z = 35

z is equal to 35 because of division property of equality.

Answer:

log (2/5)

Step-by-step explanation:

The rule/law you have in mind is as follows:  log a - log b = log (a/b).

Thus, your log 2 - log 5 = log (2/5).

Answer:

53°

Step-by-step explanation:

all triangles equal to 180°

the right hand angle is a 90° angle plus the 37° gives you 127 to find the answer you have to subtract 180 - 127 hence the answer 53°

37°+ 90° + x° = 180° (Traingle sum property)

127°+ x° = 180°

x° = 180° - 127°

x° = 53°

Hope it helps you.

BC is 120..........

Look at the picture below. Sorry if its hard to understand.

The results for the addition operation are obtained as  84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The given problem can be solved as follows,

(a) 45²/₉ + 39³/₉

⇒ 45 + 2/9 + 39 + 3/9

⇒ (45 + 39) + (2/9 + 3/9)  = 84⁵/₉

(b) -24⁵/₉ + 30⁷/₉

⇒ -24 - 5/9 + 30  + 7/9

⇒ (-24 + 30) + (7/9 - 5/9)

⇒ 6²/₉

(c) 28.98 + (-52.22)

⇒ 28.98 - 52.22

⇒ -23.24

(d) 56.75 + 75.12

⇒ 131.87

The given arithmetic operation can be matched in the form of table as,

    Sum                                    Result

45²/₉ + 39³/₉                             84⁵/₉

-24⁵/₉ + 30⁷/₉                            6²/₉

28.98 + (-52.22)                     -23.24

56.75 + 75.12                           131.87  

Hence, the given numbers are added to give result as 84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

2x + 5y < 10

Answer:

A.) 2x - 9x - 30 = -6

Step-by-step explanation:

hello !

to solve this system of equations, first, we substitute the equation [tex]y = 3x + 10[/tex] to the y variable in the equation [tex]2x-3y = -6[/tex]. Therefore, we get:

[tex]2x - 3(3x+10)=-6[/tex]

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

[tex]2x - 9x - 30 = -6[/tex]

Answer:

540

Step-by-step explanation:

1. We assume, that the number 900 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 900 is 100%, so we can write it down as 900=100%.

4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.

5. Now we have two simple equations:

1) 900=100%

2) x=3.5%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

900/x=100%/3.5%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 3.5% of 900

900/x=100/3.5

(900/x)*x=(100/3.5)*x       - we multiply both sides of the equation by x

900=28.571428571429*x       - we divide both sides of the equation by (28.571428571429) to get x

900/28.571428571429=x

31.5=x

x=31.5

now we have:

3.5% of 900=31.5
