Answer:
1/2x+b=y
1/2*4+b=3
2+b=3
b=1
1/2x+1=y
Step-by-step explanation:
4m+9+5m-12=42
9m-3=42
Divide bothsides by 9.
9m/9 -3/9=-0.3=-4
m=-4
Answer:
RM = 12 cm
Step-by-step explanation:
Assuming 20 is the hypotenuse cus there is no picture:
If It's not the hypotenuse:
But I find it unlikely that 20 wasn't the hypotenuse so ignore that unless it applies.
Hope this helped. :0)
To find the length of the wire, use the Pythagorean theorem
a^2 + b^2 = c^2
18^2 + 40^2 = c ^2
324 + 1600 = c^2
1924 = c^2
44 = c
The wire is approximately 44 feet.
Answer: B
3•5=15
Since were finding x it’s going to be
x=3y-15
It’s subtraction because obviously if you see in the problem there’s subtraction
