Answer:
Step-by-step explanation:
The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
Answer:
∠PRQ = 55°
Step-by-step explanation:
∠PRQ = ∠STQ ( corresponding angles are congruent ), hence
∠PRQ = 55°
Answer:
1. Teresa's expression s not equivalent because she did not multiply -7 and -4 correctly.
2. Bernette's expression is not an equivalent because she should multiply before subtracting.
3. Lucy's expression is equivalent because she distributed correctly.
Step-by-step explanation:
By definition, equivalent expression have the same value but they look different.
You can find equivalent expressions of any expression by simplifying.
In this case you have the following expression:
Then, you know that:
1. Teresa's answer is:
This is not an equivalent expression , because she did not multiply -7 and -4 correctly.
Remember that:
2. Bernette's answer is:
This is not an equivalent expression, because she should multiply before subtracting (She should apply the procedure Teresa applied)
3. Lucy's answer is:
This is an equivalent expression , because she distributed correctly (She multiplied each term inside the parentheses by -7)
Therefore, you can find an equivalent expression for the given expression by applying the Distributive property. Then:
