Convert:
a) 5810 to base 2
b) 101112 to base 10
Step by step would be awesome
I suppose you mean to convert 58₁₀ to base 2, and not 5810₁₀ to base 2.
Write 58 as the sum of the largest powers of 2 that you can:
58 = 32 + 26
58 = 32 + 16 + 10
58 = 32 + 16 + 8 + 2
58 = 2⁵ + 2⁴ + 2³ + 2¹
58 = 1×2⁵ + 1×2⁴ + 1×2³ + 0×2² + 1×2¹ + 0×2⁰
⇒ 58₁₀ = 111010₂
To convert from base 2 to base 10, write out and simplify the decimal expansion as in the last line of the previous example.
10111₂ = 1×2⁴ + 0×2³ + 1×2² + 1×2¹ + 1×2⁰
10111₂ = 16 + 0 + 4 + 2 + 1
⇒ 10111₂ = 23₁₀

Answer:
11
Stepbystep explanation:
Givens:
AD = 8
AC = 4y  28
y = ?
First we can see that AD and DC are equal.
note AD and AC are not equal
But 2 times the length of AD should give you AC so.....
2 x length of AD = 16 = AC
We can use the equation:
16 = 4y  28
Solve for y
16 + 28 = 4y
44 = 4y
y = 11
Therefore value of y is 11.
Given: AC = 4DC, BC = 4EC
Prove: A = D

3(y  2) = 3y  6 PLZZZZZZ HELPPP
3(y  2) = 3y  6
3y  6 = 3y  6
3y  3y =  6 + 6
0 = 0
It has ∞ solutions.
0 = 0, so 'y' can be replaced with any value & we'll still get the LHS & RHS as 0. So, the equation has ∞ solutions.

Hope it helps ⚜
Answer:
Infinitely Many Solutions
Stepbystep explanation:
3(y  2) = 3y  6
3y  6 = 3y  6 Distribute 3.
0 = 0 Combine the like terms.
Since we get the end result of 0 = 0, which is a true mathematical statement (i.e. 0 is equal to 0), we can see that regardless of the value of x, the original equation is true. So we have infinitely many equations.
Or, we can see the 2 parts as equations for 2 separate graphs. In other words, assume that we have 2 lines: y = (3x  2) and y = 3y  6. Since they both have the same m value (slope) and b value (yintercept), the 2 lines are actually overlapping. So we have infinitely many solutions because the 2 equations represent the same linear graph.
what is the equation of a line that contains points (5,3) and (0, 1)
Answer:
y = [tex]\frac{4}{5}[/tex] x  1
Stepbystep explanation:
The equation of a line in slope intercept form is
y = mx + c ( m is the slope and c the y intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}y_{1} }{x_{2}x_{1} }[/tex]
with (x₁, y₁ ) = (5, 3 ) and (x₂, y₂ ) = (0,  1 )
m = [tex]\frac{13}{05}[/tex] = [tex]\frac{4}{5}[/tex] = [tex]\frac{4}{5}[/tex]
The line crosses the y axis at (0,  1 ) ⇒ c =  1
y = [tex]\frac{4}{5}[/tex] x  1 ← equation of line
Leo wants his bowling mean to be at least 150. His scores are shown. 138, 157, 146, 129, 151
What is the lowest score for Leo’s mean to be 150.0?
(1 point)
121
146
154
179
The lowest score for Leo’s mean to be 150.0 is 179.
Mean can be described as the average of a set of numbers.
Mean = sum of number / total numbers
In order to determine the lowest score Leo can have so his mean can be at least 150, the sum of his current scores has to be determined.
Sum of scores = 138 + 157 + 146 + 129 + 151 = 721
The second step is to determine the sum of scores when his mean is 150
Sum of scores when mean is 150 = 150 x 6 = 900
Least score = 900  721 = 179

Solve 6[9  (9x  8)] + 3x = 0.
A. 2
B. 5/4
C. 32/47
D. 2/15
E. None of the above
Answer: 2
Stepbystep explanation:
distribute: 6 [ 9 − 9 + 8 ] + 3 = 0
add the numbers: 6 [ 1 7 − 9 ] + 3 = 0
rearrange terms: 6 [ − 9 + 1 7 ] + 3 = 0
distribute again: − 5 4 + 1 0 2 + 3 = 0
combine like terms: − 5 4 + 1 0 2 + 3 = 0
Subtract 102 from both sides of the equation: − 5 1 + 1 0 2 − 1 0 2 = 0 − 1 0 2
simplify:− 5 1 = − 1 0 2
Divide both sides of the equation by the same term: 51x/51 = 102/51
simplify: 2
