Answer:

x = 5/2; y = 7

Step-by-step explanation:

2x + y = 12

y = 2x + 2

Use substitution to replace y in the first equation with 2x + 2.

2x + 2x + 2 = 12

4x + 2 = 12

4x = 10

x = 10/4

x = 5/2

y = 2x + 2

y = 2(5/2) + 2 = 5 + 2

y = 7

Subtract the 2 on both sides to get -4x=-5x+7, then add -5 on both sides and get 1x=7 then divide 1 on both side to get x=7

Answer:

C) $\frac{2}{4}, \frac{2}{3}, \frac{7}{10}, \frac{4}{5}$

Step-by-step explanation:

Given fractions:

$\frac{2}{4}, \frac{4}{5}, \frac{7}{10},\frac{2}{3}$

To arrange the fractions from least to greatest.

Solution:

In order to arrange the fractions from least to greatest, we need to make the denominators common by taking LCD.

LCD of 4,5,10,3 can be found using their multiples.

4= 4,8,12,16,20,24,28,32,36,40,.........60

5= 5,10,15,20,25,30,.........60

10= 10,20,30,40,50,60

3= 3,6,9..........................60

So, 60 is the LCD.

Making the denominators common by multiplying same numbers to numerator and denominator.

$\frac{2}{4}=\frac{2\times 15}{4\times 15}=\frac{30}{60}$

$\frac{4}{5}=\frac{4\times12}{5\times 12}=\frac{48}{60}$

$\frac{7}{10}=\frac{7\times 6}{10\times 6}=\frac{42}{60}$

$\frac{2}{3}=\frac{2\times 20}{3\times 20}=\frac{40}{60}$

Comparing the numerators we can arrange the fractions.

$\frac{2}{4}, \frac{2}{3}, \frac{7}{10}, \frac{4}{5}$

Write a expression that can be used to multiply 6x198

nydimaria [60]

In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.
