The answer is -3.
To find this, we simply have to solve the equation and leave only the blank and the parenthesis that it is with on the right side. Then we can divide by the parenthesis. The work for this is done for you below.
____(x - 3) + 2x = -(x - 5) + 4 ----> Distribute the -1 to the parenthesis.
____(x + 3) + 2x = -x + 5 + 4 ----> Simplify
____(x + 3) + 2x = -x + 9 ----> Subtract 2x from both sides
____(x + 3) = -3x + 9 ------> Divide both sides by x + 3
____ = -3.
Answer:
50 feet long
Step-by-step explanation:
Use the Pythagorean theorem to find the value of the missing side. The pythagoreon theorem only works with right triangles such as this one.
a²+b²=c²
Where a and b are length of legs (sides) of a triangle. And c is the length of the hypotenuse. The hypotenuse is the side across from the right angle.
We know by looking at the image posted in the question, that one leg of the triangle is 14 feet. And another leg is 48 feet. (Length of picnic area) (length of campground)
14²+48²=c²
Simplify
196+2304=2500
Find square root of 2500
√(2500)=50
So 14²+48²=50²
The missing side is 50 feet long. The fence is 50 feet long.
Attached is another example.
Answer:
x = ± 
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ±
which can be simplified to
x = ± 2
[ ± means plus or minus ]
The correct answer is A!
A. 1/2 is equal to .5 so multiply 2,000 by .5 and you’ll get $1000. She spends $900 on rent. Since $900 is less than $1000 she is not spending more than half of her income on rent. There for this statement is False
B. If you do 2,000 multipled by .15 (which equals 15%) then you’ll get $300 and that’s how much she spends on savings. So this statement is true.
C. 1/4 = .25 so if you do 2,000 multiplied by .25 you’ll end up with $500. The total cost of utilities, cable and groceries ( 120 + 80 + 320 ) = $520 and since $500 is less than $520 then she is spending more than 1/4 of her income on those expenses. Which makes this statement true.
D. 14% is = .14 so if you do 2,000 multiplied by .14 you’ll get $280. The total of cell phone and other expenses ( 100 + 180 ) = $280 so that is true.
