Mathematics
1 answer:
yarga [219]3 years ago
8 0

Answer:

(-10, 3)

Step-by-step explanation:

You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.

Step 1: Rewrite 2nd equation

2y = 6

y = 3

Step 2: Plug in <em>y</em>

7x + 8(3) = -46

7x + 24 = -46

7x = -70

x = -10

Put it in coordinates and we have our final answer!

Hello I Really need this answered
notsponge [240]

Answer:

α =  143.13⁰

Step-by-step explanation:

Given;

Sin \ \alpha = \frac{3}{5} \ \ , \frac{\pi}{2}

α is determined as follows;

⇒find the arcsine of ³/₅

\alpha = sin^{-1}(\frac{3}{5} )\\\\\alpha = sin^{-1}(0.6)\\\\\alpha = 36.87 ^0 = 180^0 - 36.87^0 = 143.13^0

Thus, \frac{\pi}{2} < 143.13^0

Therefore, the value of α  that satisfies the given range value is 143.13⁰

Priscilla can make 2 bracelets in 12 minutes. At this rate, how many bracelets can she make in 48 minutes?
Leto [7]

Answer: Priscilla can make 8 bracelets in 48 minutes.

Step-by-step explanation:

So the givens are that:

2 bracelets in 12 minutes, how many in 48 minutes

So find the ratio of bracelets to minutes:

2/12 simplified is 1/6

So Priscilla can make 1 bracelet per 6 minutes. We just need to find how many in 48 minutes.

1/6 * 8 = 8/48

So Priscilla can make 8 bracelets in 48 minutes.

Hence your answer.
