Answer:
x=-5
Step-by-step explanation:
10x + 15 = 5x-10
-5x -5x
5x+15 = -10
-15 -15
5x = -25
/5 /5
x = -5
Answer:
the answer is B
Step-by-step explanation:
Each mark represents 20%, you move right three times. 20x3 = 60
60%
X and Z equal 72
Y equals 108.
This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
Answer:
(-2,-5)
Step-by-step explanation:
y = 2x-1
3x-y = -1
We can use substitution
3x - (2x-1) = -1
Distribute the minus sign
3x -2x+1 = -1
x +1 =-1
Subtract 1 from each side
x+1-1 = -1-1
x=-2
Now we need to find y
y = 2x-1
y = 2(-2) -1
y = -4-1
y = -5
(-2,-5)
The function rule that relates the number of miles traveled to the hours driven is d = 55t
<h3>What is speed?</h3>
Speed is the ratio of distance traveled by a body to the time taken.
The formula for calculating distance is expressed as:
Given that the speed is 55 miles per hour
55 = d/t
Cross multiply
d = 55t
Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t
