Answer:
A = 100
B = 50
C = 30
Step-by-step explanation:
You can make this equation to solve:
2x+x+x-20=180
4x-20=180
+20 +20
4x=200
divide both sides by 4
200/4 = 50
x=50, B = x = 50
2x = 100 = A
x-20 = 30 = C
Answer:
B. y=22x+10
Step-by-step explanation:
Answer:
y = 1x - 5
Step-by-step explanation:
We will use the slope equation for this: y = mx + b
y is our output/answer
m is our slope, or the rate of change
x is our x coordinate. For example, in (3,2) x would be 3.
b is our y intercept, or where the line passes through the y axis.
Knowing this, we can fill out the blanks.
when we look at one point on the grid, and then find the next closest number from the point we chose, we can see that the slope is 1 so we now have: y = 1x + b
to find b, we find where the line passes over the y axis which on our grid is -5. Normally we would write: y = 1x + 5 Since we have a negative 5 or -5, we will change the + to a -
This means we write y = 1x -5.
I hope this helps you and have a great day :D
start by dividing both sided by -5
when we have an absolute we obtain two equations, one for the positive value and one for the negative value
solve each of them
for the second equation
the solutions for k are -6.5 and 5
Answer:
x= −1/4 or x = 5
Step-by-step explanation:
Step 1: Factor left side of equation.
(4x+1)(x−5)=0
Step 2: Set factors equal to 0.
4x+1=0 or x−5=0
Answer:
x= −1/4 or x = 5
