Answer:

Step-by-step explanation:

y=5x

+5(y)=(12-x)+5  which distributing is +5y= +60-5x

y=5x

+5y=+60-5x

6y=60

y=10

10=5x

x=2

Answer:

<u>x = 3</u>

Step-by-step explanation:

y = 5x

x + y = 12

x + 5x = 12 (substitute 5x in the place of y)

6x = 12

x = 12/6

Answer:

Speed = 21.43m/s

Step-by-step explanation:

Given

Distance = 1200m -- of the roadworks

Time\ Recorded = 56s

Required

Determine the speed

In this case:

Speed = \frac{Distance\ of\ Roadword}{Time\ Captured}

Speed = \frac{1200m}{56s}

<em></em>Speed = 21.43m/s<em> --- approximated</em>

What is the median of the following data values? 108,102,43,100,22
PolarNik [594]

<u>Answer:</u> 100

<u>Reasoning:</u> The median is the "middle value" and to find it put the numbers in order from least to greatest.

22, 43, 100, 102, 108.

now take a number from both sides

43, 100, 102

Once again.

100

So 100 is the median.

Angle e measures 126LaTeX: ^\circ∘. What is the measure of LaTeX: \angle∠h?
Oksana_A [137]

Option C: 126° is the correct answer

Step-by-step explanation:

When two lines intersect, the four angles are formed. The angles vertically opposite with same vertex are called vertical opposite angles.

The opposite vertical angles are equal.

In the given figure, the pairs of vertically opposite angles are e,h and f,g.

Given

∠e = 126°

The measurement of e and h will be equal as they are vertically opposite

So,

m∠e = m∠h

m∠h = 126°

Hence,

Option C: 126° is the correct answer

Keywords: Vertical angles, lines

What two numbers would make:<br> a + b = -11<br> AND<br> a x b = 28
ycow [4]

The first step I would do would be to list the factors of 28.

28(1)

14(2)

7(4)

Now notice that 7 + 4 = 11

So that means that -7 + -4 = -11.

Therefore, -7(-4) = 28

Your two numbers are - 7 and - 4.  Hope that helps!
