What is x ? please help :)

Mathematics
1 answer:
bekas [8.4K]4 years ago
3 0

Answer:

x =12

Step-by-step explanation:

The two angles are complementary, so the add to 90 degrees

5x+1/2x +24 = 90

Combine like terms

5 1/2 x +24 = 90

Subtract 24 from each side

5 1/2 x = 90-24

Change the mixed number to an improper fraction

11/2 x = 66

Multiply by the reciprocal 2/11 on each side

2/11 *11/2 x = 66*2/11

x = 6*2

x =12

Type the correct answer in each box. Use numerals instead of words. Consider this quadratic equation. x2 + 2x + 7 = 21 The numbe
Zolol [24]

Answer:

(a) 1

(b) 1

(c) 3.03

Step-by-step explanation:

The given quadratic equation is

Subtract 27 from both sides.

Taking out common factor.

Divide both sides by 4.

If an expression is , then we need to add , to make it perfect square.

Here, b=2, so

Add 1 on both sides.

Taking square root on both sides.

Subtract 1 from both sides.

and

and

Only one solution is positive.

Greatest solution is 3.031, therefore the approximate value of this solution is 3.03.

6x + 3y = 24<br><br> But if you show the work for it, (step by step) I will mark brainliest!
daser333 [38]

Answer:

If solving for y: y = 8 - 2x

If solving for x: x = \frac{8 - y}{2}

Step-by-step explanation:

<u>To solve for y:</u>

Factor out the common term, which in this case is 3.

3(2x + y) = 24

Divide both sides by 3.

2x + y = \frac{24}{3}

Simplify \frac{24}{3} to 8.

2x + y = 8

Subtract 2x from both sides.

y = 8 - 2x

<u>To solve for x: </u>

Factor out the common term, which in this case is 3.

3(2x + y) = 24

Divide both sides by 3.

2x + y = \frac{24}{3}

Simplify \frac{24}{3} to 8.

2x + y = 8

Subtract y from both sides.

2x = 8 − y

Divide both sides by 2.

x = \frac{8 - y}{2}

Can you help i give 50 points
Citrus2011 [14]

Answer:

IF It is a right angle triangle then it's one angle

is of 90 degree

Other angle given is 32degree

And sum of all angle of triangle is 180 degree

Therefore by angle sum property

Missing angle =180 - (90+32)

Missing angle =180 - 113

Missing angle =67

The third angle is 6 7 degree

If you are helped with my answer pls tag me brianliest I really want it

THANK YOU.....
