Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

From the given:

$18 ——→ 1 home

$90 ——→ x home

Cross multiply the above and make x the subject of formula.

[tex]18x = 90[/tex]

Now, divide both sides by 18 to find the value of x.

[tex] \frac{18x}{18} = \frac{90}{18} [/tex]

Therefore:

Tim made $90 from cleaning 5 homes.

Answer:

[tex] \frac{9}{20} [/tex]

Step-by-step explanation:

[tex] \frac{3}{4} \times \frac{9}{15} [/tex]

The denominator 15 will be divided by the numerator 3 giving :

[tex] \frac{1}{4} \times \frac{9}{5} \\ = \frac{1 \times 9}{4 \times 5} [/tex]

Final answer:

[tex] \frac{9}{20} \: or \: 0.45[/tex]

Answer:

a) 3m + 4 = 6m is false.

Step-by-step explanation:

A) 3m + 4 = 6m

→ 3(6) + 4 = 6(5)

→ 18 + 4 = 30

→ [ 22 ≠ 30 ]

So, the equation is false.

B) -5(t - 7) = 10

→ -5(5 - 7) = 10

→ -5 × -2 = 10

→ [ 10 = 10 ]

So, the equation is true.

C) 17 = 4x - 3

→ 17 = 4(5) - 3

→ 17 = 20 - 3

→ [ 17 = 17 ]

So, the equation is true.

D) t + 9 = 14

→ 5 + 9 = 14

→ [ 14 = 14 ]

So, the equation is true.

The coordinates of the vertices after a reflection over the line x = -1 are

A’ = (-12, 3).

B' = (-1, -7)

C' = (-12, -6)

Given that the coordinates of the vertices after a reflection over the line

x = -1.

For reflection about a vertical axis (x = -1), we need only be concerned with the x-components of the vertices.

Given any point (x, y), the new x’ value would be the distance ‘d’ from the reflection axis (x -(-1)), then inverted for reflection about the axis of reflection x = -1… x’ = -1 -d… where d = (x - (-1)) = (x + 1)

x’ = -1 -(x + 1) = -x -2

Given a point  from the graph as

A = (-10, -7), A’ = (-10-2 , -7) = (-12, 3).

B = (-1, -7), B’ = (-1, -7) = (-1, -7). (since on the same line.)

C = (-10, -6), C’ = (-10-2, -6) = (-12, -6).

This reflection works for vertices on either side of the reflection axis, such as if you have a triangle with some vertices on one side, and some on the other, straddling the axis.

The coordinates of the vertices after a reflection over the line x = -1 are

A’ = (-12, 3).

B' = (-1, -7)

C' = (-12, -6)

We have been provided with this exponential equation y=   13√x + 13√[tex]x^{7}[/tex]

The product rule for solving the exponential powers is [tex]x^{n}[/tex] × [tex]x^{m}[/tex]= [tex]x^{n+m}[/tex]

, which means if the base is same and the variables are multiplied then the powers of the bases get added.

By using the product rule in the given exponential problem, it can be written as:

y = 13 √x ×√[tex]x^{7}[/tex]

y =13 √[tex]x^{1+7}[/tex]

y =13 √[tex]x^{8}[/tex]

The scale of a map is 1:500 000. The actual area of the lake in km is 3x10¹² km².

The ratio between a distance on a map and its actual distance on the ground is known as the map's scale. Since scale must vary throughout a map due to the curvature of the Earth's surface, this straightforward idea is made more difficult.

• If 1 centimeter on a map corresponds to 500 000 km on the earth, then 1 cm2 would be equivalent to 1 cm² = (500000km) 2

=25×10¹⁰ km²

• The lake's exact area may now be determined by multiplying 12 cm² by 25 × 10¹⁰ km² (3 × 10¹² km²)

As a result, the distance between the towns is 0.000344 cm on the map, while the lake's real area is 3x10¹² km².

(Option a) Gonzalez and Bros . Inc has the absolute advantage when it comes to producing phones.

Absolute advantage theory

Adam Smith, an economist from the 18th century, introduced the idea of absolute advantage in his book The Wealth of Nations to explain how nations might profit from trade by specializing in producing and exporting the things that they can manufacture more successfully than other nations.

On the other hand, low-cost manufactured items are produced and exported by China, Thailand, and Vietnam. These three nations enjoy a distinct advantage as a result of their significantly reduced unit labor costs.

Step-by-step explanation:

We find the jump between every 2 terms :

7 - 1 = 6

13 - 7 = 6

19 - 13 = 6

Now we know this will be the co-efficient of n and the 0th term will be added to the term :

m is the average number of miles which is 4.3 miles

Total miles Genesis travel in a week is 42.8 miles.

Here we have to find m which is the average number of miles she would travel.

She ride for 6 more days and had already traveled 5 miles.

From the above question, we have an equation

5 + 6m = 42.8

6m = 37.8

m = 6.3

Therefore m is 6.3 which is the average number of miles Genesis will ride to meet her goal.

B. x=5±√3

Step-by-step explanation:

Let's solve your equation step-by-step.

(x−5)²=3

Step 1: Simplify both sides of the equation.

x²−10x+25=3

Step 2: Subtract 3 from both sides.

x²−10x+25−3=3−3

x²−10x+22=0

For this equation: a=1, b=-10, c=22

1x²+−10x+22=0

Step 3: Use quadratic formula with a=1, b=-10, c=22.

x=−b±√b²−4ac/2a

x=−(−10)±√(−10)²−4(1)(22)/2(1)

x=10±√12/2

The complete question is attached below.

The equation y = 3/5x + 3 can be plotted to represent the graph of -3x + 5y = 15

The equation of the plot is given as

-3x + 5y = 15

Divide through the equation of the plot by 5

So, we have

-3/5x + y = 3

Add 3/5x to both sides of the equation

So, we have

y = 3/5x + 3

The above means that the equation y = 3/5x + 3 can be plotted to represent the graph of -3x + 5y = 15

Hence, the equation y = 3/5x + 3 can be plotted to represent the graph of -3x + 5y = 15
