Answer:
C = F - 32 /(9/5)
Step-by-step explanation:
F = (9/5)C + 32
Subtract 32 from both sides
F - 32 = (9/5)C + 32 - 32
F - 32 = (9/5)C
Divide both sides by (9/5)
F - 32/(9/5) = (9/5)C/(9/5)
F - 32/(9/5) = C
C = F - 32 /(9/5)
Answer: -18=v
Step-by-step explanation: You subtract 8 from both sides. -10-8=-18 which will equal to v.
Answer:
Always.
Step-by-step explanation:
Congruent means equal in mathematics. And equilateral triangles' sides are <u>always</u> equal. Therefore, always is your answer.

Answer: Choice B</h3>
Positive, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is positive
=======================================================
Explanation:
Recall we have these rules
- positive times positive = positive
- positive times negative = negative
- negative times negative = positive
Here is one example for each rule
- 8*7 = 56
- 5*(-9) = -45
- -2*(-4) = 8
So based on that, we know that (-5)(-3) is positive. The two negatives cancel each other out so to speak. The same goes for (-8)(-6). Then multiplying any two positive numbers produces another positive outcome.
Answer:
See explanation
Step-by-step explanation:
(i) Consider triangles ABC and ADC. In these triangles:
- - given;
- - given;
- - reflective property.
So, by SAS postulate.
(ii) Congruent triangles have congruent corresponding parts:
(a)
(b)
(c) Line segment AC bisects and
