Given parallelogram ABCD, solve for x
Answer:
x=5
Step-by-step explanation:
Set your equation up as following:
6x-10=3x+5
move the 3x to the left side by substracting
3x-10=5
now add 10 to the right side
3x=15
Divide 15 by 3 to isolate x
x=15/3
x=5

Answer:
The height of the square pyramid is 24 unit.Step-by-step explanation:
Given that:
Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unitTo Find:
The height of the square pyramid.We know that:
In pythagoras theorem.
H² = P² + B²Where,
H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unitFinding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
The height of the square pyramid = 24 unitIf 6 - 7 = -1, which of the following is true?
-1 + 7 = 6
-1 + (-7) = 6
7 - 6 = -1
7 - (-1) = 6
Answer:
B is true
Step-by-step explanation:
Which equation represents the linear relationship between x and y that is shown in the
table below?
Answer:
y= 5-x
Step-by-step explanation:
We notice that when we put 5 for x we get 0 which means that we must be subtracting the given x value by constant
y= 5-x makes sense, try plugging in any x value given in table and you will get its y counterpart back.
For eg, when x= -1
y= 5- (-1) = 6 (negatives add)

The total number of cars produced by TESLA each year is y = 200000(1.25)x , where x represents the number of years after 2020. how many cars will be produced in year 2025 (five years later)?
Answer:
y=1250000
Step-by-step explanation:
Multiply 200000 by 1.25.
y = 250000 ⋅5
Multiply 250000 by 5.
y=1250000

Step-by-step explanation:
choose two ecspresstion that are eqilivent to 5 (3a+4b)
a. 15a + 4b
b. 15a +20b
c.5a+3a+4b
d. 5a+10a b+3b
e. 10a +5a +15b +3b
Answer:
b. 15a +20b
Step-by-step explanation:
Given:
5 (3a+4b)
= 15a + 20b
a. 15a + 4b
Not equivalent
b. 15a +20b
Equivalent
c.5a+3a+4b
= 8a + 4b
Not equivalent
d. 5a+10a b+3b
= 15a + 4b
Not equivalent
e. 10a +5a +15b +3b
= 15a + 18b
Not equivalent
What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points
