Answer:

x = -11

Step-by-step explanation:

First, get rid of parentheses:

5 + x - 2 = -8

Then, simplify:

3 + x = -8

Finally, subtract 3 on both sides:

x = -11

Hope this helps ^^

Can someone please give me the answer to the second part of this question?<br> Thank You!

Answer:

$\theta=30\textdegree$

Step-by-step explanation:

$(ii)\ \sqrt{3}\tan\ \theta=2\sin \theta\\\\substitute\ \tan\theta=\frac{\sin\theta}{\cos\theta}\\\\\sqrt{3}\frac{\sin\theta}{\cos\theta}=2\sin\theta\\\\Divide\ both\ sides\ by\ \sin\theta.\\\\\sqrt{3}\frac{\sin\theta}{\cos\theta\times \sin\theta}=\frac{2\sin\theta}{\sin\theta}\\\\\frac{\sqrt{3}}{\cos\theta}=\frac{2}{1}\\\\Apply\ cross\ multiplication\\\\2\cos\theta=\sqrt{3}\\\\divide\ both\ sides\ by\ 2\\\\\frac{2\cos\theta}{2}=\frac{\sqrt{3}}{2}\\\\\cos\theta=\frac{\sqrt{3}}{2}\\\\$

$\cos\theta=\cos\ 30\textdegree\\\\\theta=30\textdegree$

Set tay equal to x, and set Omar to be equal to y. Then solve for x, which is done simply by dividing both sides by the y value. The answer is your slope

1) Jason's football team lost 6 yards from their starting positions and then lost five yards. What number represents a loss of 6

djyliett [7]

Ans: Let it started from zero. And it lasts 6 yards means that -6 represents a loss of 6 yards.

After that, the team lost 5 yards. So, -11 will represent a loss of 5 yards

<span>The team after gaining 12 yards on next day will not be at their starting position. Instead, it will be at ‘1yard’ more than the starting position. The number will be ‘1’ which will represent the position of the team after gaining 12 yards.</span>

1/4b^2+ 4bc + 16c?<br> Answer?

Charra [1.4K]

Answer:

1/4b^2+ 4bc + 16c?=4

Step-by-step explanation:

STEP

Simplify —

Equation at the end of step

((— • b2) + 4bc) + 16c

STEP

Equation at the end of step 2

(—— + 4bc) + 16c

STEP

Rewriting the whole as an Equivalent Fraction

3.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 4 as the denominator :

4bc 4bc • 4

4bc = ——— = ———————

1 4

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

b2 + 4bc • 4 b2 + 16bc

———————————— = —————————

4 4

Equation at the end of step

(b2 + 16bc)

——————————— + 16c

STEP

Rewriting the whole as an Equivalent Fraction

4.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 4 as the denominator :

16c 16c • 4

16c = ——— = ———————

1 4

STEP

Pulling out like terms

5.1 Pull out like factors :

b2 + 16bc = b • (b + 16c)

Adding fractions that have a common denominator :

5.2 Adding up the two equivalent fractions

b • (b+16c) + 16c • 4 b2 + 16bc + 64c

————————————————————— = ———————————————

4 4
