Answer:
m = -5
Step-by-step explanation:
1/5 m = -1
Multiply each side by 5
5*1/5 m = -1*5
m = -5
If Joe collected 94 stamps which are in April May and June, we could make an equation like this: A + M + J = All stamps
Plug in the values:
Isolate J:
Combine like terms:
He collected 33 stamps in June.
Answer:
30 inches
Step-by-step explanation:
The circumference of a circle can be found by using 2r, or * d.
Since we are given the circumference of the circle, 30, you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.
To cancel out you can divide both sides of the equation by pi. Now you have:
30 = d
Therefore the diameter of the circle is 30 inches.

Step-by-step explanation:
Answer:
These lines will be perpendicular when m = ³⁄₂
Step-by-step explanation:
Two lines are perpendicular when the product of their gradients equal to -1. So:
m₁ * m₂ = -1
Let's get the first equation in gradient-intercept form (same as equation two).
2x + 3y = 4
3y = -2x + 4
y = -⅔x + ⁴⁄₃
We know the first gradient, and now we can find the gradient of the second line (which when multiplied will result in -1 as these lines are perpendicular). So:
-⅔ * m₂ = -1
m₂ = ³⁄₂
