Mathematics
1 answer:
aivan3 [116]4 years ago
6 0

Answers:

  • A
  • C
  • D

Step-by-step explanation:

<em>We must simplify each option to see if they are equivalent to -\frac{3}{8}.</em>

<em>Lets try A.</em>

-\frac{6}{16} can be simplified to -\frac{3}{8} by dividing both the numerator and denominator by 3.

-\frac{6}{16} ÷ \frac{3}{3} = -\frac{3}{8}

A is correct!

<em>Lets try B</em>

\frac{12}{32} simplifies to \frac{3}{8}. However, because this answer is not negative, it is not equivalent.

<em>Lets try C</em>

There is a negative in the numerator, making this fraction negative. So yes, \frac{-3}{8} = -\frac{3}{8}.

  • Bonus Info: If there was a negative in both the numerator and denominator, the two negatives would cancel eachother out, making the fraction positive

C is correct!

<em>Lastly, Lets try D</em>

There is a negative in the denominator, so this fraction is negative. \frac{9}{-24} can be simplified by dividing by 3 to -\frac{3}{8}.

\frac{9}{-24} ÷3 = -\frac{3}{8}

D is correct!

  • Hope this helped you!~

<h2>210 gaL 60 % Antifreeze II</h2>

Step-by-step explanation:

In the problem, there are two types of antifreeze

antifreeze I and

antifreeze II

antifreeeze I 20 ----70 gal

Antifreeze II 60 ----- x gal

Total 50 ---------------- (70 + x ) gal

20*70+60*x=50(70+x)

1400+60x=3500+50x

60x-50x=3500-1400

10x=2100

x= 210

x=210 gaL 60 % Antifreeze II

Jerry has just purchased his first home for $190,000. He put down a 20 percent down payment of $38,000 and took out a 5 percent
shepuryov [24]

Answer:

$66.67

Step-by-step explanation:

The calculation of first monthly mortgage payment is amortization is given below:-

Amount borrowed = Purchase first home cost - Down payment

= $190,000 - $38,000

= $152,000

Annual interest = ($152,000 × 5%) ÷ 12

= $7,600 ÷ 12

= $633.33 per month

Now,

First monthly payment = Mortgage payment - Annual interest

= $700 - $633.33

= $66.67

Hence, we simply applied the above formula.
