Challenge Question:

Here is a system with four linear equations.

x+a=6
x-b=5
x+c=4
x-d=3

what is the value of a+b+c+d​

Answer:

Absolute change = 3%

Relative change = 100%

Step-by-step explanation:

Current percentage = 3%

Upcoming percentage = 6%

Absolute change :

Relative change :

Absolute change = (upcoming percentage - current year percentage)

Absolute change = 6% - 3% = 3%

Relative change :

[(upcoming percentage - current year percentage) / current year percentage] * 100%

[(6% - 3%) / 3%] * 100%

(3% / 3%) * 100%

1 * 100%

= 100%

Step-by-step explanation: When triangles are similar, all of their angles should be equal to their respective angles on the other triangle.

[tex]on \: this \: farm \: there \: are \to \\ \underline{ \boxed{17 \: pigs }}\: \\ and \\ \underline{ \boxed{28 \:chickens}}[/tex]

Answer:

The two column proof is presented as follows;

The given parameters are;

[tex]\overline {AD}[/tex] = [tex]\overline {DC}[/tex] and [tex]\overline {AB}[/tex] = [tex]\overline {BC}[/tex]

Statement               [tex]{}[/tex]                     Reason

[tex]\overline {AD}[/tex] = [tex]\overline {DC}[/tex] and [tex]\overline {AB}[/tex] = [tex]\overline {BC}[/tex]       [tex]{}[/tex]       Given

[tex]\overline {BD}[/tex]  ≅  [tex]\overline {BD}[/tex]               [tex]{}[/tex]                    Reflexive property

[tex]\overline {BD}[/tex]  =  [tex]\overline {BD}[/tex]               [tex]{}[/tex]                     By the definition of congruency

ΔADB ≅ ΔCDB             [tex]{}[/tex]                By Side-Side-Side (SSS) rule of congruency

ΔADB = ΔCDB              [tex]{}[/tex]                 By the definition of congruency

If the three sides of one triangle are congruent to the corresponding three sides of another triangle, then both triangles are said to be congruent according to the SSS rule of congruency

Answer:

y = x + 1

Step-by-step explanation:

1) First, find the slope of the line between the two points. Whichever option has the same slope would be the right answer. To find this, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point.

So, use the points given to answer the question. Substitute 4 for [tex]x_1[/tex], 5 for [tex]y_1[/tex], 8 for [tex]x_2[/tex], and 9 for [tex]y_2[/tex] then solve:

[tex]\frac{(9)-(5)}{(8)-(4)} \\= \frac{9-5}{8-4} \\= \frac{4}{4} \\= 1[/tex]

Therefore, the slope is 1.

2) Any line that is in a "y = a number" format is a horizontal line, and all horizontal lines have a slope of 0 - so the second option can't be the answer.

The rest of the options are in slope-intercept form, or y = mx + b format. Remember that the coefficient of the term with the x is the slope. Knowing this, y = x + 1 would need to be the answer since the coefficient of the term with the x is 1, and we already calculated that the slope is 1.

Answer:

Solving it would turn into these:

(20x+37)/ x- 5

20+ (137/x-5)

Step-by-step explanation:

Your problem → 5y+5/2 / 25y-20/40y^2-32y

5y+5/2÷25y-20/40y^2-32y

=5⋅y+5/2÷25×y-20/40×y^2-32×y

=5y+5/2÷25×y-20/40×y^2-32y

=5y+5/2×1/25×y-20/40×y^2-32y

=5y+y/10-20/40×y^2-32y

=5y+y/10-y^2/2-32y

=5y×10+y-y^2×5-32y×10 ÷ 10

=50y+y-5y2-320y ÷ 10

= -269y-5y^2 / 10

Answer:

Emmanuel will walk 510 miles in 1.7 hours.

Step-by-step explanation:

Given that Emmanuel walks at an average speed of 5 m/min.

It means:

As there are 60 minutes in 1 hour.

so

1.7 hours = 102 minutes

Thus,

The walking distance in 102 minutes = 5 × 102

                                                             = 510 miles     ∵ 1 min = 5 miles

Therefore, Emmanuel will walk 510 miles in 1.7 hours.

Answer:

Choice B

Step-by-step explanation:

He is currently 40 inches in height.

He needs to be 48 inches in height to ride the roller coaster.

He is growing 1.2 inches per month (m)

So, 40 + 1.2m ≥ 48

40 inches + average gain per month has to be greater or equal to (≥) 48 inches.

Answer:

they sold 210 hot chocolates and 85 coffees

Step-by-step explanation:

We know that they sold $200 worth of drinks

x will be the number of hot chocolates sold

y will be the number of coffees sold

This means that

.75x+.5y=200

We also know that they sold 295 total drinks which means that

x+y=295

This is a system of linear equations which I will solve through substitution

x+y=295

Subtract y from both sides and divide by -1 to get

-x+295=y

Plug y into the first equation and get

.75x+.5(-x+295)=200

Distribute the .5 and simplify to get

.75x-.5x+147.5

.25x+147.5=200

Subtract 147.5 and then divide by .25 to get our x value

x=210

Now we can go back and plug this in into our equation

210+y=295

Subtract 210 to get y

y=85

This means that they sold 210 hot chocolates and 85 coffees

Answer:

It will cost her $27 to drive 336 miles.

Step-by-step explanation:

With the information provided, you can use a rule of three to find how much it will cost to drive 336 miles given that driving 28 miles costs $2.25:

28 miles     →    $2.25

336 miles    →         x

x=(336*2.25)/28= 27

According to this, the answer is that it will cost her $27 to drive 336 miles.

Answer:

3.26$

Step-by-step explanation:

Simply subtract one from another to find the difference in the cost.

Answer:

If using simple interest, the formula is:

= Amount * ( 1 + rate * time)

= 20,000 * ( 1 + 4% * 5)

= $24,000

Interest = Balance after 5 years - Investment

= 24,000 - 20,000

= $4,000

Using Compound Interest:

= Amount * ( 1 + rate)^time

= 20,000 * ( 1 + 4%)⁵

= $24,333.06

Interest = 24,333.06 - 20,000

= $4,333.06
