Answer:
x = 4
y = 3
Step-by-step explanation:
2x - 3(x - 1) = -1
2x - 3x + 3 = -1
-x + 3 = -1
- 3 - 3
(-1) -x = -4 (-1)
x = 4
y = 4 - 1
y = 3
Answer:
x = 4, and y = 3

Four friends were born in consecutive years. The sum of their
ages is 94. What is the age of the oldest friend?
Answer:
25
Step-by-step explanation:
Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.
Now we add the 4 expressions and set the sum equal to 94.
x + x + 1 + x + 2 + x + 3 = 94
4x + 6 = 94
4x = 88
x = 22
The youngest one is 22.
The oldest one is
x + 3 = 22 + 3 = 25

Pls help me with my homework
Answer:
b = 8
Step-by-step explanation:
Using Pythagorean Theorem, a[tex]a^{2} +b^{2} =c^{2}[/tex], we just plug in what we know.
We know that the hypotenuse, c, is 10 km. We also know that one of the other side lengths is 6 km, we can plug that into either a or b.
Now, our equation will be: [tex]6^{2} +b^{2} =10^{2}[/tex].
You could also use the equation: [tex]b^{2} =10^{2} -6^{2}[/tex].
Next, we'll just solve the equation.
[tex]10^{2} =100[/tex], [tex]6^{2} = 36[/tex]
[tex]b^{2} =100 - 36[/tex]
[tex]b^{2} = 64[/tex]
[tex]\sqrt{b^{2} } = \sqrt{64}[/tex]
b = 8

A triangle has sides of length 3 cm, 5 cm, and 7 cm.
Find the size of the largest angle in the triangle,
Answer:
C=120 degrees
Step-by-step explanation:
We can use the law of cosines to find an angle when we have all three sides
(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)
49 = 25 +9 -30Cos(c)
49= 34 -30Cos(c)
15 = -30Cos(c)
Cos(c) = -1/2
C=120 degrees
Please anyone help please ASAP
Answer:
Angle WTS will be 180 degree minus 15x. You can write this as an expression:
180-15x
Now you have an expression for each angle in the triangle. Triangles will always have 180 degrees in them. You can add the expressions together and set it equal to 180. Then you can solve the equation for the x variable.
Step-by-step explanation:
Angle SWT + angle WTS + angle TSW = 180 degrees
Replace each angle with the expression then solve.
Answer:
x=7.90 x≈8
Step-by-step explanation:
they are alternate interior angles
so: 7x+6+15x=180
22x+6=180
22x=174
=7.9090......

Calculate the value of (6.72 x 10^5) + (3.2 x 10^4)
Give your answer in standard form.
Answer:
7.04× 10^5
Step-by-step explanation:
6.72 x 10^5= 6.72 x 10^(4+1)= 6.72 x 10^1 ×10^4
= 67.2 x 10^4
(67.2 x 10^4)+ (3.2 x 10^4)

Answer:
the awnser is 135
Step-by-step explanation:
15 × 9 = 135
Answer:
54 m^2
Step-by-step explanation:
Area = 1/2 * base * height
You are missing height, but because you have the hypotenuse, you can use the Pythagorean Theorem to find it.
height^2 + (9m)^2 = (15m)^2
height = sqrt(225 m^2 - 81 m^2)
height = sqrt(144 m^2) = 12m
Area = 1/2 * 9m * 12m = 54 m^2

3(3v-5) = 39
Simplify your answer as much as possible.
Answer:
v = 6
Step-by-step explanation:
Given
3(3v-5) = 39
So,
3v - 5 = 39 / 3
=> 3v - 5 = 13
=> 3v = 13 + 5
=> 3v = 18
=> v = 18 / 3
=> v = 6
#HopeItHelps
Answer:
V=6
Step-by-step explanation:
Hope this helped! :)
Simplifying
3(3v + -5) = 39
Reorder the terms:
3(-5 + 3v) = 39
(-5 * 3 + 3v * 3) = 39
(-15 + 9v) = 39
Solving
-15 + 9v = 39
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 9v = 39 + 15
Combine like terms: -15 + 15 = 0
0 + 9v = 39 + 15
9v = 39 + 15
Combine like terms: 39 + 15 = 54
9v = 54
Divide each side by '9'.
v = 6
Simplifying
v = 6

Factor the expression using 3 as one factor. 3x−30
Answer:
3(x - 10)
Step-by-step explanation:
3x - 30 = 3(x - 10)
Hii!
__________________________________________________________
Answer:
3(x-10)
Step-by-step explanation:
Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.
The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain
x-10
Put parentheses around x-10
(x-10)
Next, put 3 outside the parentheses
3(x-10)
