Blood Pressure A person’s blood pressure is measured with two numbers. The systolic blood pressure measures the pressure of the blood on the arteries as the heart beats. The diastolic blood pressure measures the pressure while the heart is resting. (a) Let x be your systolic blood pressure. Researchand then write the compound inequality that shows you what a normal systolic blood pressure should be for someone your age. (b) Let y be your diastolic blood pressure. Researchand then write the compound inequality that shows you what a normal diastolic blood pressure should be for someone your age.

Daniel is creating a rectangular garden in his backyard. The length of the garden is 14 feet. The perimeter of the garden must be at least 58 feet and no more than 66 feet. Use a compound inequality to find the range of values for the width w of the garden.
Han wants to build a dog house. He makes a list of the materials needed:
At least 60 square feet of plywood for the surfaces
At least 36 feet of wood planks for the frame of the dog house
Between 1 and 2 quarts of paint
Han's budget is $65. Plywood costs $0.70 per square foot, planks of wood cost $0.10 per foot, and paint costs $8 per quart.
Write inequalities to represent the material constraints and cost constraints in this situation. Be sure to specify what your variables represent.
