#4)
cross multiply
2(8x+10) = 4 * 5x
16x + 20 = 20x
4x = 20
x = 5
I tried subtraction addition multiplication and division and I am still very confused on this
I think it’s C because a triangle is 180 degrees and it’s a right triangle which means there is a 90 degrees angle + 30 degrees.
90+30=120. 180-120=60
Which means the third angle is 60 degrees
Answer:
Q2: slope = -½
Q3: slope = 1
Step-by-step explanation:
If the equation of the line is in the form y = mx+b, then m is the slope of the line and b is the y-intercept (the point where the line crosses the x-axis).
y = -½x, so the slope of the line is -½
y = x+15, so the slope of the line is 1
