Can someone help me with algebraic method

Mathematics
1 answer:
Lina20 [59]3 years ago
4 0

Answer:

<em>x = -8; y = 0</em>

Step-by-step explanation:

x + 2y = -8

3x - 4y = -24

We will use the substitution method.

Solve the first equation for x.

x = -8 - 2y

Replace x of the second equation with <em>-8 - 2y</em>, and solve for y.

3<em>x</em> - 4y = -24

3<em>(-8 - 2y)</em> - 4y = -24

-24 - 6y - 4y = -24

-24 - 10y = -24

-10y = 0

y = 0

Now we substitute 0 for y in the first original equation and solve for x.

x + 2y = -8

x + 2(0) = -8

x + 0 = -8

x = -8

Solution: x = -8; y = 0

Aldon and Jamal raised the same amount of money for the school fundraiser. Aldon
Naddika [18.5K]

Answer: $5

Step-by-step explanation: This can be represented by the equation

40 + 12T = 25 + 15T

We just solve for T.

Subtract 12T from both sides

40 = 25 + 3T Subtract 25

15 = 3T Divide by 3

5 = T

If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m
nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

\angle1=2(17)+6\\\angle1=34+6\\\angle1=40

So, the actual measure of ∠1 = 40°

Show that (3*8*x)^7 = 6^7*4^7*x^7
Sergeeva-Olga [200]

Answer:

24x^7 = 24x^7

Step-by-step explanation:

Left side of equation: 3 times 8 times X = 24x

Then you raise it to the 7th power

Right side of the equation: 6 times 4 times X = 24x

Since the exponent is the same, you keep it as the 7th power
