Step-by-step explanation:
3+6=9 9x7=63
Answer: 6
Step-by-step explanation:
You can set the unknown number as x and then you would add 3 to x and multiply that by 7.
The equation would be 7(x+3)=63
7(x+3)=63
7x+21=63
7x=42
x=6
The answer is 6

Use the Pythagorean Theorem to find the missing length. Round your answer to the
nearest tenth.
In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .
= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )
= 25 + 25 = x²
= 50 = x²
= 7.0710678119 = x
But they have given that we have to round it off to the nearest tenths , so ;
= 7.0710678119 will be equal to = 7.10
= 7.1 = x
Therefore , the length of the unknown side x = 7.1 .
If the side lengths of a Triangle are: 2t, t, 3t, and the perimeter is equal to 60 meters; what is the value of t? a 20 b 12 c 10 d 6
Answer:
x equals 10
Step-by-step explanation:
so so you if the perimeter is 60 and when you measure perimeter you add up all these sides so you would add 2t + t + 3t = 60 then you would divide by 6 and get 10.

You spend 30 minutes watching television . You then spend 2 hours playing video games . Write the ratio of the amount of time spent to the amount of time spent as a fraction in simplest form.
The ratio in simplest form is ???
Answer:
television/ video games= 1/4
Step-by-step explanation:
cuz there are 2 sets of 30 min in an hour, make the video games time 4 sets of 30 min, and the tv time 1 set. so , the ratio would be 1/4.
The ratio of the amount of time spent on watching television to the amount of time spent on playing video games as a fraction in the simplest form is 1 : 4.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Time spend on watching television = 30 minutes.
And time spend on playing video games = 2 hours.
To find the ratio of the amount of time spent on watching television to the amount of time spent on playing video games,
Use ration property,
Ratio = time spend on watching television/ time spend on playing video games
= 30 minutes / 2 hours
= 30 minutes / 2 x 60 minutes
= 1 / 4
Ratio = 1 : 4
The required ratio of time spend on television to time spend on playing video games is 1 : 4.

Write an equation of the line that passes through (2,−5) and is parallel to the line 2y=3x+10
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c
[tex] \frac{2}{2} y = \frac{3}{2} x + \frac{10}{2} [/tex]
y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
[tex]y = \frac{3}{2} x - 8[/tex]

Two step equations x−17/3=−3
Answer:
[tex]\boxed {x = \frac{8}{3}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x - \frac{17}{3} = -3[/tex]
-Add both sides by [tex]\frac{17}{3}[/tex] and convert [tex]-3[/tex] to a fraction [tex]-\frac{9}{3}[/tex]:
[tex]x - \frac{17}{3} + \frac{17}{3} = -3 + \frac{17}{3}[/tex]
[tex]x = -\frac{9}{3} + \frac{17}{3}[/tex]
-Since both [tex]-\frac{9}{3}[/tex] and [tex]\frac{17}{3}[/tex] have the same denominator, then you would add the numerators:
[tex]x = \frac{-9 + 17}{3}[/tex]
[tex]\boxed {x = \frac{8}{3}}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]\frac{8}{3}[/tex].
