Answer:

Yes, BC || DE

Step-by-step explanation:

set up proportion and cross multiply to solve:

15/10 = 12/8

120 = 120

This is true! You can justify by explaining how you cross multiplied like the bold words above :)

Answer:

-8

Step-by-step explanation:

what do you think, when you look at the examples given in the problem definition ?

don't you see the pattern, that f(x) = x+2 ?

f(1) = 1+2 = 3

f(2) = 2+2 = 4

f(3) = 3+2 = 5

so, if we follow this assumption, then

f(-10) = -10 + 2 = -8

Each small square on this scale weighs 1 unit. Each larger square weighs 10 units. The weight of the triangle x is unknown. The
Iteru [2.4K]

The equation to represent the relationship of the weights shown on the scale s 22 + x = 34

The weights are given as:

Small\ Square = 1

Larger\ Square = 10

The total weight on one side, where there are 4 small squares and 3 large squares is:

Total =4\times Small\ Square + 3 \times  Larger\ Square

Total =4\times 1 + 3 \times  10

Total =34

The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:

Total =2\times Small\ Square + 2 \times  Larger\ Square + 1\times triangle

Total =2\times 1+ 2 \times  10+ 1\times triangle

Total =2+ 20+ 1\times triangle

Total =22+ 1\times triangle

Total =22+ triangle

The weight of the triangle is x.

So, we have:

Total =22+ x

The weights on both sides are equal, because the scale is balanced.

So, we have:

22 + x = 34

Hence, the equation is 22 + x = 34

Classify the system of equations -1/2x=3-y -7+y=1/2x-2
miskamm [114]

Answer: Inconsistent.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Solve for "y" in each equation:

<em>Equation 1</em>

-\frac{1}{2}x=3-y\\\\y=\frac{1}{2}x+3

<em>Equation 2</em>

<em> -7+y=\frac{1}{2}x-2\\\\y=\frac{1}{2}x-2+7\\\\y=\frac{1}{2}x+5</em>

<em> </em>

You can notice that the slope of the <em>Equation 1 </em>is:

m_1=\frac{1}{2}

And the slope of the <em>Equation 2 </em>is:

m_2=\frac{1}{2}

Observev that m_1=m_2, then you can conclude that the lines are parallel and the System of equations has No solution.

When there is no solution the classification  of the system of equations is: "Inconsistent".

Witch one is greater 21 ft or 17 yd
morpeh [17]
First, you want to find out how many feet in a yard

3ft=1yd

so you do 21/3 to get your yard, and the answer is 7 yard

17 yard is greater than 7 yard so 17 is the answer
