Use the substitution method from using the mutiple choices.
The two numbers must equal to each other.
x= 2
(2+50)/2= 13(2)
add first then divide
(52)/2= 13(2)
26= 26
Answer: x= 2
Answer:
$70
Step-by-step explanation:
According to the problem, calculation of given data are as follows:
Spending money at rate = $5 per day
After 9 days money left = $25
We can calculate the money on day 0 by using following formula,
y = mx + b
Here, y = money left after 9 days
m = rate of spending money
x = number of days
b = money on day 0
So, by putting value, we get
$25 = (-5 × 9 ) + b
b = $25 + $45
= $70
Answer:
4√6
Step-by-step explanation:
The line marked x meets the base of the isosceles triangle at its midpoint, so dividing the triangle into two congruent right triangles with leg 5 and hypotenuse 11.
The Pythagorean theorem can be used to find x:
5² + x² = 11²
x² = 121 -25 . . . . . . subtract 25 from both sides of the equation
x = √96 . . . . . . . . . take the square root
x = 4√6 . . . . . . . . . simplify the radical
Point slope uses one point and the slope. We’ll use (4,10)
Y - 10 = 2 • (x - 4)
But it can also be
Y - 4 = 2 • (x - 1)
Whichever you prefer to use
