4z ≥ 7
divide seven by four
z ≥ 1.75
or, if you need it in fraction form, it would be
z ≥ 7/4
Answer:
3x=78+(x-2)
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles.
3x=78+(x-2)
Let the amount saving by Sienna and Jacob be x
Sienna has $8 and is saving $3 per week
So the equation will be 3x + 8
Jacob has $6 and is saving $4 per week
So the equation will be 4x + 6
Sienna will have same amount as Jacob, so
3x + 8 = 4x + 6
So the model two will represents the equation that Sienna will have same amount as Jacob.
Answer: 15 cm
Step-by-step explanation:
The formula for calculate the area of a rectangle is:

Where "l" is the lenght and "w" is the width.
You know that the area of this rectangle is 75 square centimeters and the width is 5 centimeters. Then, you can substitute these values into the formula
and solve for the lenght. Then you get:

Therefore, the lenght of the rectangle is 15 centimeters.
