Substitution method 4x + y = 14 6x - 3y = 3

lakkis [162]

Answer:

x = 2.5
y = 4

Step-by-step explanation:

We know that:

4x + y = 14
6x - 3y = 3

Let's first solve for y by choosing any equation.

4x + y = 14
=> y = 14 - 4x

Now, let's substitute the value of y into the second equation.

6x - 3y = 3
=> 6x - 3(14 - 4x) = 3
=> 6x - 42 + 12x = 3
=> 18x - 42 = 3
=> 18x = 42 + 3
=> 18x = 45
=> x = 45/18 = 5/2 = 2.5

Now, let's substitute the value of x into the equation of y.

=> 14 - 4x = y
=> 14 - 4(2.5) = y
=> 14 - 10 = y
=> y = 4

Hence, the value of x and y are 2.5 and 4 respectively.

Find the least common multiple of 4, 2, and 7

amm1812

Answer:

Step-by-step explanation:

So we know that 2 is already a multiple of 4 so we can just find the least common multiple of 4 and 7. So we can do:

4, 8, 12, 16, 20, 24, 28

7, 14, 21, 28

So the least common multiple between 4, 2, and 7 is 28

Convert the following Standard Form equation to an equation in General For (x-7)^2 + (y + 3)^2 = 49

Harman [31]

Answer:

x+y=11

Step-by-step explanation:

take the square root of both sides.

(x-7) + (y+3) = 7

collect like terms

x+y = 7+7-3

Sean used 3/4 cup of sugar to make a dozen brownies. How much sugar is in each brownie

Law Incorporation [45]

So. how many times 12 goes into 3/4?

$\bf \cfrac{\quad \frac{3}{4}\quad }{12}\implies \cfrac{\quad \frac{3}{4}\quad }{\frac{12}{1}}\implies \cfrac{3}{4}\cdot \cfrac{1}{12}\implies \cfrac{3}{48}\implies \cfrac{1}{16}$

If angle 1 is 110°, what would the other angle measures

lana66690 [7]

Answer:

Angle 2= 110 degrees

Angle 3 = 70 degrees

Angle 4 = 70 degrees

Step-by-step explanation:

Finding angle 2

In the figure attached below,the angles 1 and 2 Corresponding angles

When two lines are crossed by another line that is called the Transversal, then, the angles in matching corners are called corresponding angles.

Corresponding angles are equal so

angle 2 = 110 degrees

Finding angle 3

Similarly 2 and 3 are consecutive angles and Consecutive angles are supplementary . That is the sum of the consecutive angles is 180 degree

then

angle 2 +angle 3 = 180

110 + angle 3 = 180

angle 3 = 180 -110

angle 3 = 70 degrees

Finding angle 4

Now angle 3 and angle 4 are alternate interior angle and they are equal

angle 3 = angle 4

so angle 4 is 70 degree
