Answer:
You have to translate these sentences into expressions. I am not going to solve all of these because if I explain one/two problems to you, you'll get the hang of it. Seven more than three times a number: 7+3x; Five times a number decreased by six: 5x-6
Step-by-step explanation:
Why? We don't know what number that is, so we can put any variable like (x, y, z, a, b, etc.). Three times a number is simply that number times 3. In this case we would input: 3*x, or 3x. 7 more than that number is 3x+7. Five times a number decreased by six: 5x-6 . Remember: it is simply 5*x which simplifies to 5x. Decreased is take away, so take away 6, and get 5x-6
Key words: Quotient: the result after dividing two/or more numbers; Product: the result after multiplying two/ or more numbers; Decreased: take away (Example: x decreased by 7=x-7)
I hope you understand!! It is very simple after you start to get the hang of it!!
A (−3, 1) and B (3, 4)
2 Let A have coordinates (x1, y1). Let (x1, y1) = (−3, 1).
3 Let B have coordinates (x2, y2). Let (x2, y2) = (3, 4).
4 Find the length AB by applying the
formula for the distance between
two points.
AB = "(x2 − x1)2 + (y2 − y1)2
= "[3 − (−3)]2 + (4 − 1)2
= "(6)2 + (3)2
= !36 + 9
= !45
= 3!5
= 6.71 1
Answer:
8 15/16 inches
Step-by-step explanation:
just multiply 2 3/4 by 3 1/4
Answer:
27/250
Step-by-step explanation:
P(a green grape and a seedless tangerine)
=P(green grape) x P(seedless tangerine)
The bowl of grapes has 9 green grapes and 16 red grapes.
P(green grape)=green grapes / total grapes
=9/(9+16)
=9/25
The bowl of tangerines has 7 seeded and 3 seedless tangerines.
P(seedless tangerine)=seedless / total
=3/(3+7)
=3/10
P(a green grape and a seedless tangerine)
=9/25 x 3/10
=27/250
Answer:
C. Angles X and Z are supplementary
Step-by-step explanation:
A: This is true because in Angle Y, a right angle is shown. A right angle is worth 90°.
B: This is true because X, Y, and Z are supplementary (add to 180), and given that Angle Y is 90 degrees, 180 - 90. Thus, they're complementary.
C: This is false and the correct answer choice because Angle Y exists too. Angle X and Z, added together, would make 90 degrees, not 180.
D: This is true because Angles Y and Z are right next to each other, and that's what adjacent means.
Therefore, the answer is C.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
