Answer:

ans: D

Step-by-step explanation:

suppose

y = 3x +1 be equation••••••1

and

y = -2x - 4

-y= 2x + 4 be equation ••••••2

add equation 1 and 2 as

y = 3x + 1

<u>-y</u><u> </u><u>=</u><u> </u><u>2x</u><u> </u><u>+</u><u> </u><u>4</u><u> </u>

0 = 5x + 5

so ,

5x = - 5

x = - 1

put x In either equation 1 or 2 to get y= - 2

OR,

since given equation intersects each other ,

use substitution method ,

Answer:

Step-by-step explanation:

Step 1: Find the total fraction of raisins he gave to his brothers

=

Step 2: Find the lowest common multiple(Lcm) of 6 and 4

Lcm of 6 and 4 = 12

Step 3: Add the fractions

= \frac{2+ 3}{12}

= \frac{5}{12}

Step 4: To find the fraction that he kept, you will subtract the total fractions he gave his brothers from 1.

1 - \frac{5}{12} \\= \frac{12-5}{12} \\= \frac{7}{12}

Final answer

The fraction that he kept = \frac{7}{12}

Estimate the answer by rounding each fraction to the nearest whole number and then adding.
Natasha_Volkova [10]

Answer:

24

Step-by-step explanation:

<u>First, we round the fractions. </u>

If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.

7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.

1/8 is less than half so we round down and remove the fraction so we are left with 10.

<u>Then we add.</u>

14+10=24

Tom [10]

Answer:

3¼

Step-by-step explanation:

formula \frac{{y}^{2} - {y}^{1}  }{ {x}^{2} -  {x}^{1}  }

We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).

x¹ = -3

y¹ = 1

x² = 1

y² = 14

Now, we sub these figures into the formula.

\frac{14 - 1}{1 - ( - 3)}

This leaves us with 14-1/1+3, which we can make into 13/4

13/4 = 3¼
