Brent has $26 when he went to the fair. After playing 7 games, he had $15.50 left. Solve 15.50 = 26 - 7p to find the price for e
AveGali [126]

Step 1: Simplify both sides of the equation.

15.5=26−7p

15.5=−7p+26

Step 2: Flip the equation.

−7p+26=15.5

Step 3: Subtract 26 from both sides.

−7p+26=15.5

      -26 -26

−7p=−10.5

Step 4: Divide both sides by -7.

-7p = -10.5

/-7     /-7

Answer:

P = $1.5 (Price for each game)

Hope this helps!

One angle in an obtuse isosceles triangle measures 40°. What are the measures of the other two angles?
Damm [24]
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°.
40^\circ + 40^\circ +x = 180^\circ \\
80^\circ + x=180^\circ \\
x=180^\circ - 80^\circ \\
x=100^\circ
The other two angles are 40° and 100°.

ASAP! I really need help with this question! No nonsense answers, and please attach the solution.

Answer:

\boxed{\sf Option \ 4}

Step-by-step explanation:

\sqrt{2x-3} +x=3

Subtract x from both sides.

\sqrt{2x-3} +x-x=-x+3

\sqrt{2x-3}=-x+3

Square both sides.

( \sqrt{2x-3})^2 =(-x+3)^2

2x-3=x^2-6x+9

Subtract x²-6x+9 from both sides.

2x-3-(x^2-6x+9 )=x^2-6x+9-(x^2-6x+9)

-x^2 +8x-12=0

Factor left side of the equation.

(-x+2)(x-6)=0

Set factors equal to 0.

-x+2=0\\-x=-2\\x=2

x-6=0\\x=6

Check if the solutions are extraneous or not.

Plug x as 2.

\sqrt{2(2)-3} +2=3\\ \sqrt{4-3} +2=3\\\sqrt{1} +2=3\\3=3

x = 2 works in the equation.

Plug x as 6.

\sqrt{2(6)-3} +6=3\\ \sqrt{12-3} +6=3\\\sqrt{9} +6=3\\3+6=3\\9=3

x = 6 does not work in the equation.

here's your answer looking for⤵
This a similar triangle problem.
If you consider the two horizontal
sides (shadows) as a ratio 32/4
Consider the corresponding vertical sides
x and 8
32/4= x/8 Cross multiply 
4x= 256
x = 64
Therefore the tree is 64 feet high.
