Answer:
x=17 plz the brainliest!
Step-by-step explanation:
3x+39=90
3x+39-39=90-39
3x=51
\frac{3x}{3}=\frac{51}{3}
x=17
Answer:
b = 33m is the answer
Step-by-step explanation:
a = 44m
b = ?
c = 55m
According to the Pythagoras theorem,
a² + b² = c²
44² + b² = 55²
1936 + b² = 3025
b² = 3025 - 1936
b² = 1089
b = 33m
∴ b = 33m is the length of the missing leg.
After 1 hour he has driven 40 miles
x is a variable. You need to find the variable to complete the equation.
ex. x = 1
x to the power of 5 (1x5x5x5x5x5)
1*x(0)=0
Answer:
<em>C. y = 3x + 13.</em>
Step-by-step explanation:
The point slope form of a line is
y - y1 = m(x - x1) where m = the slope, and (x1, y1) is a point on the line.
So, substituting:
y - 1 = 3(x - -4)
y - 1 = 3(x + 4)
y = 3x + 12 + 1
y = 3x + 13.
