5x + 3y = 6

Answer's too short so here's some extra text.

Answer:

A) x = 7

Step-by-step explanation:

7x + 1 + 7x + 6 + (180° - 15x) = 180°

14x + 7 + 180° - 15x = 180°

combine like terms:

-x = -7

x = 7

Answer:

x = - 12, 3

Step-by-step explanation:

By tangent secant theorem:

[tex]x(x + 9) = {6}^{2} \\ \\ {x}^{2} + 9x = 36 \\ \\ {x}^{2} + 9x - 36 = 0 \\ \\ {x}^{2} + 12x - 3x - 36 = 0 \\ \\ x(x + 12) - 3(x + 12) = 0 \\ \\ (x + 12)(x - 3) = 0 \\ \\ x + 12 = 0, \: \: x - 3 = 0 \\ \\ x = - 12, \: \: x = 3 \\ \\ [/tex]

Answer:

It has no solution.

Step-by-step explanation:

6x + 3 + 4x = 9 + 10x

10x + 3 = 9 + 10x

10x + 3 - 3 = 9 - 3 + 10x

10x = 6 + 10x

10x - 10x = 6 + 10x - 10x

0 ≠ 6

It has no solution.

Answer:

+ or - 0.044

Step-by-step explanation:

The margin of error is 0.044.

A Margin of Error is defined as the results will vary from the actual population value by how many percentage points, as indicated by the margin of error.

The margin of error using this formula, where z is the critical value.

[tex]ME = z\sqrt{\dfrac{T(1 - t)}{n} }[/tex]

To determine a margin of error for a sample proportion,

Where n is the sample size and is the sample proportion, these assumptions must be true.

n t ≥ 10

n(1 - t) ≥ 10

Write the proportion of lead to significant as a decimal number first,

42%

= 0.42

Now substitute the sample proportion and the sample size, 479, the assumptions are inserted into the equations to see if they are satisfied.

⇒(479X0.42) 201.18

⇒ (479)(1 − 0.42)

⇒  277.82

Both values are greater than 10, so the assumptions are satisfied, and the margin of error can be calculated.

Determine the margin of error using this formula, where z is the critical value.

[tex]ME = z\sqrt{\dfrac{T(1 - t)}{n} }[/tex]

For a 95% confidence level, z = 1.96.

Substitute the values of z, n, and T into the formula for margin of error and evaluate.

[tex]ME = 1.96\sqrt{\dfrac{0.42(1 - (10.42)}{479} }[/tex]

ME ≈ 0.044

Hence, the margin of error is 0.044.

Answer:

Probability = 1/5 = 20%

Step-by-step explanation:

Prob (1st marble green) = Green Marbles / Total Marbles = 3/6 = 1/2

Pr (2nd marble red), without replacement = Red Marbles / Left Total Marbles = 2/5

Prob (1st marble green, & 2nd marble red) = 1/2 x 2/5 = 1/5

Prob in percent = 1/5 x 100 = 20%

Step-by-step explanation:

Answer:

The baby gained 29 oz.

Step-by-step explanation:

1 pound is equal to 16 oz (ounces).

10 pounds is equal to 10 x 16 oz = 160 oz.

8 pounds and 3 oz is equal to (8 x 16) + 3 = 128 + 3 = 131 oz.

160 oz - 131 oz = 29 oz.

The baby gained 29 oz.

Step-by-step explanation:

Let's solve your inequality step-by-step.

2x+3/ −3 ≤1

Step 1: Simplify both sides of the inequality.

−2/ 3 x−1≤1

Step 2: Add 1 to both sides.

−2/ 3 x−1+1≤1+1

−2/ 3 x≤2

Step 3: Multiply both sides by 3/(-2).

( 3/ −2 )*( −2/ 3 x)≤( 3/ −2 )*(2)
