Answer:
x=-2
y=9
Step-by-step explanation:
Multiply one of the equations to get negative terms with equal y coefficients. Add them together then solve for x.
Substitute x in one of the equations then solve for y.
You can check your answer by substituting x and y into one equation and solving to obtain the same answer on the right side of the equation.

The length of s2, the sides of the base of the larger prism, is 18 cm. How many times as great as V1, the volume of the smaller prism, is V2, the volume of the larger prism?
A)3
B)8
C)24

Rewrite each equation without using absolute value for the given conditions. y=|x−3|+|x+2|−|x−5|, if x>5
Step-by-step explanation:
If x >5 then |x-3| is just x-3
|x+2| is just x + 2
|x-5| is also just x-5
so this just becomes (x-3) + (x+2) - (x-5)

What are the first two steps of drawing a triangle that has all side lengths equal to 12 centimeters?
Select from the drop-down menus to correctly complete the statements.
Draw a segment (6, 12, 24) centimeters long. Then from one endpoint, draw a (30, 60, 90) ° angle.
Answer:
All the sides should be 4 cm.
Step-by-step explanation:
The first triangle rule is the two sides should be greater than the longest side when added together.
For example- 4+4=8 which is bigger than 4
12 divided by 3 is 4.
Hope this helps.
Answer:
Step-by-step explanation:
Remark
All triangles have 180 degrees.
In order that all sides be 12cm long, you need to draw a base line that goes on for more than 12 cm.
Mark off the (using a ruler) a line that is 12 cm from one of the line written about.
From that same endpoint, draw an angle that is 60o. Draw a line going 60 degrees from your first line.
=============
Just to finish the triangle, go to the other end of the 12 cm line. Draw another 60 degree angle. Make it so that it will intersect the second line you drew.\

A map has a scale of 1 cm : 30 km. If 2 cities are 4.7 cm apart on the map, how far apart are they in reality?
Answer:
141 Km apart.
Step-by-step explanation:
so if each 1 cm is equivalent to 30 km, we would take the 4.7 and multiply it by the 30 to get the true value.
the true value would come out to be 141 km apart.
Please mark this as brainlest.
141 miles away.
Explanation? Common sense, no?
We are given the unit rate, so we can convert it easily.
1cm = 30km, so, multiply it by 4.7 as there are 4.7cm that are present.
30km x 4.7 = 141km in real life.
Find the value for? to make the equation true. Enter the answer in the box.
Answer:
the answer is 0.35
Step-by-step explanation:
You need to multiply the denominator (10) by a hundred in order to add them together but you also need to multiply the number above that(0.35) and it becomes 3.5, that multiplied by 8 is 28. Hope it helped

Answer:
1/3*5/4=5/12
Step-by-step explanation:
the common denetominter for 3 and 4 is 12
3 goes into 12 4 times and 4 goes into 12 3 times
then you multiply the top by how many you have to mutiply by the bottom.
then you times that which equal 19/12 which in simplifest form is 5/12
Which is the best use for the converse of the Pythagorean theorem?
to show that all triangles have a right angle
to prove that a triangle is equilateral
to determine from the side lengths if a triangle is a right triangle
to find the length of an unknown side of a right triangle
Answer:
here you go
Step-by-step explanation:
The converse of the Pythagorean Theorem tells us that by comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.
To determine from the side lengths if a triangle is a right triangle. Therefore, the correct answer is option C.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
The converse of Pythagoras theorem states that “If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right angle triangle”.
By comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.
Therefore, option C is the correct answer.

Jim $ = m
Keenan $ = d
m+49=d ; d-49=m
btw please lmk if i get this wrong
Answer:
m + 49 ≥ d - 49
Explanation:
m + 49 is the money that Keenan makes.
d - 49 is the money Jim makes.

Answer:
6
Step-by-step explanation:
The required measure of the radius of the sphere is given as 6 cm.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Here,
A right triangle is drawn inside a sphere, and the hypotenuse is 12 cm.
As we know, for a right triangle inscribed in a circle, the hypotenuse represents the circle's diameter,
hypotenuse = diameter
12 = diameter
radius = diameter / 2
radius = 12/2
radius = 6 cm
Thus, the required measure of the radius of the sphere is given as 6 cm.
