7(x+4)=-21
what does x equals
CORRECT answers ONLY please
Answer: x = -7
Step-by-step explanation:
7 (x + 4) = -21
7x + 28 = -21
Subtract 28 from both sides
7x = -49
Divide both sides by 7
x = -7
Answer:
x = -7
Step-by-step explanation:
first distribute he 7 to get 7x + 28 = -21
then subtract 28 from both sides to get 7x = -49
lastly divide 7 from both sides to get x = -7

Solve for the variable "x" in this example
Answer:
x=9
Step-by-step explanation:
these are vertical angles, so they equal eachother!
12x-3=105
move three to the other side of the equals sign
12x=108
divide both sides by 108
x=9
Answer: x=9
Step-by-step explanation:
These angles are equal, so you can set 105 equal to 12x-3. Add 3 and divide by 12 to get x=9.
City y is 10 miles north of city x city z is 24 miles east of city x how long is the straight roads connecting cities y and z?
Answer:
26 miles
Step-by-step explanation:
Using Pythagoras rule :
d = straight road connecting city Y and Z :
d = sqrt(xy² + xz²)
d = sqrt(10² + 24²)
d = sqrt(100 + 576)
d = sqrt(676)
d = 26 miles

Answer:

Step-by-step explanation:
Answer:
55 °
Here's the way i got my answer :
Complementary angles are two angles that have a sum of 90° ,therefore 35° + X = 90°
X=55° .
to get ∠DBF
180° - 90° = 90 °
to get ∠EBF
∠CBD + ∠DBE + ∠EBF = 180°
35° + 90° + ∠EBF = 180°
∠EBF = 55°

y=4-x
Trevor stated that (4,0) is the solution to the system of equations. Joey stated that (0, -2) is the solution to the system of equations. Which
conclusion is true?
Answer:
Trevor is right
Step-by-step explanation:
The solution of system of equations are [tex](4,0)[/tex]
Therefore, Trevor conclusion is true.
System of equations:Given system of equations;
[tex]x- 2y = 4\\\\y=4-x[/tex]
Substitute value of y from equation (2) in equation (1).
[tex]x-2(4-x)=4\\\\x-8+2x=4\\\\3x=12\\\\\\x=12/3=4[/tex]
Substitute value of x in second equation.
[tex]y=4-x=4-4=0[/tex]
Hence, the solution of system of equations are [tex](4,0)[/tex]

Find the exact value of x.
Answer:
x = 15
Step-by-step explanation:
use pythagorean theorem (a^2+b^2=c^2)
you have c^2 and one of the sides so you just reverse the equation and do
17^2-8^2
and that gives you 225
when you [tex]\sqrt{225}[/tex], you get 15 as your answer

2x+4y is the equivalent expression of x+x+4y.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is x + x + 4y
x plus x plus four times of y.
In the given expression x and y are two variables.
Equivalent expressions are expressions whose value will remain same after simplifying or solving.
We need to add x variable terms once and then with y term
x + x + 4y
2x+4y
Hence, 2x+4y is the equivalent expression of x+x+4y.

what is the surface area
Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
Answer:
748 ft²
Step-by-step explanation:
For the surface area, you need to add up the area of all sides, six in this example, but it can be simplified into three by multiplying some of them by two as its presumed a rectangle
x1 = 5*14*2 = 140
x2 = 16*14*2 = 448
x3 =16*5*2 = 160
You find the sum of these; 140 + 160 + 448 = 300 + 448 = 748

Subtract 4 from 60 to get 56.
−7y=56
Divide both sides by −7.
y=−56/7
Divide 56 by −7 to get −8.
