Answer:
Louis needs to save 15+39 = $ 54 dollars
Step-by-step explanation:
\begin{aligned} 15 + 39 &=& \\ 10 + 5 + 30 + 9 &=&\\ 10 + 30 + 5 + 9 &=&\\ 40 + 10 + 4 &=&\\ 54. \end{aligned}
So Louis needs to save \$54.
Answer:
21
Step-by-step explanation:
We need to utilise one important angle in order to answer this question which is
→ Angles in a triangle add up to 180°
Using this information we can set up an equation to find the value of x
⇒ Form equation using the important angle fact
→ x - 4 + 3x + 100 = 180
⇒ Simplify the 'x' and the numerical terms
→ 4x + 96 = 180
⇒ Minus 96 from both sides to isolate 4x
→ 4x = 84
⇒ Divide both sides by 4 to isolate x
→ x = 21
The value of x is 21
The denominator of a fraction can't be equal to 0.
The function is undefined at x=-1, x=2, x=4, because for these values the denominator of the function would equal 0, and it's impossible to divide by 0.
Edward is correct.
Answer:
x=4
Step-by-step explanation:
x/3-1/2=5/6
Add 1/2 to each side
x/3-1/2+1/2=5/6+1/2
x/3 = 5/6+1/2
Get a common denominator on the right
x/3 = 5/6+3/6
x/3 = 8/6
x/3 = 4/3
Multiply each side by 3
x/3 *3 = 4/3*3
x = 4
