Solve the system of linear equations by substitution. y=2x+5 y=3x−1

Mathematics
1 answer:
xz_007 [3.2K]3 years ago
6 0

Answer:

x = 6, y = 17

Step-by-step explanation:

since both equations are equal to the same variable (y), they are equal to each other.

2x + 5 = 3x - 1

-2x -2x

5 = x - 1

+1 +1

6 = x

y = 2(6) + 5

y = 12 + 5

y = 17

Write the ratio 4/7 over 1/8 in simplest form. How is the simplest form of the ratio 4/7 over 1/8 related to the simplest form o
PIT_PIT [208]

Answer:

Step-by-step explanation:

Ratio = 4/7 : 1/8

        =\frac{\frac{4}{7}}{\frac{1}{8}}\\\\=\frac{4}{7}*\frac{8}{1}\\\\=\frac{32}{7}

       = 32 : 7

\frac{\frac{1}{8}}{\frac{4}{7}}=\frac{1}{8}*\frac{7}{4}\\\\=\frac{7}{32}

= 7 : 32

Ratio 4/7 over 1/8  is the multiplicative inverse of the ratio 1/8 over 4/7

Deacon had 12 1/3 ounces of juice, but he drank 3 2/3 ounces. How much juice is left?
alexandr1967 [171]
You need to know:

a  \frac{b}{c} = a + \frac{b}{c} = \frac{(a*c) + b}{c}

Be careful though:

a \frac{b}{c} ≠ a(\frac{b}{c})

Using this principle, we can say:
12 1/3 = 37/3
3 2/3 = 11/3
Quantity of juice left = Initial quantity - Quantity drunk
So:
Quantity of juice left = 37/3 - 11/3 = 26/3

There will be 26/3 ounces of juice remaining after 3 2/3 are drunk from the total of 12 1/3 ounces that Deacon had initially.

Find the midpoint of the segment below and enter its coordinates as an
kodGreya [7K]

Answer:

(\frac{5}{2}, 3)

Step-by-step explanation:

I got 5/2 as my x variable and 3 for my y variable to being the midpoint. In which I added both my x variables provided ( 3 and 2 ) and then I divided them by two to get half of that (since you are looking for in between those two digits technically so you are wanting to find the midpoint or the middle of that line segment). I also did the same with the two y variables as well which were 7 and -1, then I divided both by two to get the variable 3.
