120/100 = x/15
100x = 1800 (Divide by 100 on both sides)
x = 18
Answer:
∠2 and ∠4 are the supplementary angle.
Step-by-step explanation:
Shelves of the bookcase are parallel and a transversal line is intersecting these points at two distinct points.
By the property,
Sum of two interior consecutive angles measure 180°.
From the figure attached,
∠2 and ∠4 are the interior consecutive angles.
Therefore, m∠2 + m∠4 = 180°
Which proves that shelves of the showcase are parallel.
Answer:
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<h3>y=-15x-5 and 11x+y=-17</h3>
First, you have to substitute.
Then, you solve.
Add by 5 from both sides.
-4x-5+5=-17+5
Solve.
-17+5=-12
-4x=-12
Divide by -4 from both sides.
-4x/-4=-12/-4
Solve.
-12/-4=3
<u>x=3</u>
y=-15*3-5
Solve.
PEMDAS stands for:
- Parenthesis
- Exponents
- Multiply
- Divide
- Add
- Subtract
15*3=45
Rewrite the problem down.
y=-45-5
Solve.
<u>y=-50</u>
<u>Therefore, the correct answer is y=-50 and x=3.</u>
I hope this helps you! Let me know if my answer is wrong or not.
Answer: x=6
Step-by-step explanation:
To solve for x, we want to isolate the variable.
[get common denominator]
[add fractions]
[combine like terms]
[multiply both sides by 8]
[subtract both sides by 14]
[divide both sides by 15]
Now, we know that x=6.
To find the height you would take 85/ π 3² which would give you 3.00626
