Enter a number in each box so that the expressions are equivalent. (A) 0.8 (2x + x) + 3(7 - 4.1x) = x + 21 (B) 12 1 2 (6x + 22y) = x + y (C) (3x - ) - (6x + 1) = -3x - 2 (D) 112 1 2 x + 27y = (12 1 2 x + 9y)
The questions aren't well formatted ; from the values that are observable,
Answer:
Coefficient of x = -9.9 ;
Coefficient of x = 75
Coefficient of y = 275
Step-by-step explanation:
Given :
0.8 (2x + x) + 3(7 - 4.1x) = __x + 21
0.8(3x) + 21 - 12.3x = __x + 21
2.4x + 21 - 12.3x = __x + 21
-9.9x + 21 = __x + 21
-9.9
12 1/2 (6x + 22y) = x + y
75x + 275y = x + y
Answer:
The answers are:
1. -9.9x
2. 3x + 11y
3. 1
4. 3

-2x/3 + 11 = 14 please help me its not letting me put stuff I want
Answer:
x = -4 1/2
Step-by-step explanation:
-2x/3 + 11 = 14
subtract 11 from each side of the equation:
-2x/3 = 3
multiply both sides by 3:
-2x = 9
divide both sides by -2:
x = -4 1/2

Answer:
z = 5
Step-by-step explanation:
[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]
It can be also written as -
[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]
Using law of exponents , lets solve this.
[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]
[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]
[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]
[tex]=> y^z = y^5[/tex]
[tex]=> z = 5[/tex]

Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°
9514 1404 393
Answer:
73°
Step-by-step explanation:
A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.
-647° +720° = 73°
The least positive measure angle coterminal with A is 73°.
