Answer:

x = 1

Step-by-step explanation (work shown in attached pictures):

1) You can find x by using the elimination method. First, multiply the second equation by -1 in order to make the coefficient of the y-term -1. This makes it so that when we add the two equations, the y-terms will cancel out, leaving the x-terms for us to solve.

2) Now, add the two equations together and cancel the two y-terms out. With the resulting equation, isolate x to find its values. So, the resulting answer is x = 1.

Answer:

13

Step-by-step explanation:

71-6=65

65/5=13

therefore the answer is 13

5d + 6 = 71

5d = 71 - 6

5d = 65

d = 65/5

d = 13

Answer:

I walk at a rate of 4 miles per hour, while the car travels at 10 miles per hour.

Step-by-step explanation:

Since I can walk 14 miles in the same time that it takes to travel 35 miles by car, if the car's rate is 6 miles per hour faster than my walking rate, to find the average rate of each the following calculation must be performed:

35 - 14 = 21

21/6 = 3.5

35 / 3.5 = 10

14 / 3.5 = 4

So, I walk at a rate of 4 miles per hour, while the car travels at 10 miles per hour.

maybe since the rhombus is divided into triangles it'll be easier. x = 8

Step-by-step explanation:

the total degrees in a triangle would be 180 and the inner little angles would be 90 degrees so you would solve for (7x - 1) + (4x + 3) + 90 = 180 so 11x + 2 = 90 so 11x = 88 so x = 8

Answer:

He loses 100 Rs. during the process of buying and selling.

Step-by-step explanation:

1. When he bought 40 bulbs for 800 it meant that every bulb is 20 Rs. worth.

2. 10 of them were broken which means its -200 Rs. from the 800 he spent which leads to him losing 200 Rs.

3. He sold the remaining for 30 Rs. each and he had 30, which means 30 x 30 = 900 Rs.

4. We see that he got 100 more Rs. from the original price he bought the 40 bulbs for but 10 bulbs were lost throughout the way.

( Now there are 2 scenarios in this case )

1. The 10 remaining bulbs were to be lost as in the part of the profit he gained from selling the light bulbs for 30 Rs. which would lead to him losing 200 Rs. because he couldve sold the 10 if they werent broken.

2. The 10 remaining bulbs were to be lost as in part of the original price he bought them for which was 20 Rs. per light bulb which means that if they werent broken he couldve sold them for 100 Rs. .

( Now you may ask me why isnt it 300 Rs. in the first scenario and 200 Rs. in the second its because he gained 100 Rs. in the process of selling the light bulbs that werent broken. So we add 100 Rs. in both scenarios/cases )

I chose the second scenario because it seemed very reasonable to me, but you do as you see preferable.

I hope this helped have a good day!

Answer:

Profit %= 50%

Step-by-step explanation:

Price for 40 bulbs: Rs.800

Price for 1 bulb each: 800/40= Rs 20

Price for 10 bulbs= 10*20=Rs. 200

This means that Rs. 200 were wasted due to 10 bulbs being broken.

The remaining bulbs; 30 are sold at a price of Rs 30 each.....

In reality, the price of the remaining 30 bulbs: 30*20=600

Since the 30 bulbs are sold at the price of 30, they altogether cost 30*30=900

Profit=  SP-CP; Profit= 900- 600= Rs 300

Profit%= 300*100/600= 50%

[4m(2.5m)(100^2cm^2/m^2)]/10^2cm^2=1000 tiles

Answer: 1000

Step-by-step explanation:

10xm×10cm=100cm

400cm×250cm=100000cm

100000cm²÷100cm²=1000

Answer:

14

Step-by-step explanation:

Average rate of change is given as [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

a = 4,

f(a) = f(4) = (4)² + 3(4) = 16 + 12 = 28

b = 7,

f(b) = f(7) = (7)² + 3(7) = 49 + 21 = 70

Plug in the values into the formula

Average rate of change = [tex] \frac{70 - 28}{7 - 4} [/tex]

[tex] = \frac{42}{3} = 14 [/tex]

Answer:

Peanuts

Step-by-step explanation:

Answer:

peanuts

Step-by-step explanation:

Answer:

Diagram 1:

a = 54°

b = 54°

Diagram 2:

a = 74°

b = 106°

c = 106°

d = 65°

e = 65°

Step-by-step explanation:

Diagram 1:

a = 54° (alternate angles are equal)

b = a (vertically opposite angles are equal)

a = 54°

Therefore,

b = 54°

Diagram 2:

a = 74° (alternate angles are equal)

a + b = 180 (sum of angles on a straight line)

74 + b = 180

Collect like terms

b = 180 – 74

b = 106°

74 + c = 180 (sum of angles on a straight line)

74 + c = 180

Collect like terms

c = 180 – 74

c = 106°

d = 65° (corresponding angles are equal)

e = d (vertically opposite angles are equal)

d = 65°

Therefore,

e = 65°

Step-by-step explanation:

3.65 / 100 = 0.0365

Another way to figure out the answer is by moving the decimal point two times to left ( division goes left, multiplicatin goes right)

If you move the decimal point to left 2 times in 3.65, you will get 0.0365

Answer:

Image result for how many bases does a trapezoid have

two bases

A trapezoid has two bases, each of which is one of the parallel sides. The other two sides that aren't parallel to each other are called the trapezoid's legs. Since only the bases are parallel and the legs are not, we can think of this scenario as two nonparallel transversals cutting across a pair of parallel lines.

Step-by-step explanation:

Step-by-step explanation:

1. the claim here is that over 60 percents of the households living in ann harbor have pets.

null hypothesis;

h0: p≤0.60

alternative:

h1: p>0.60

2.

n is the size of the sample = 280

n(p) = 280 x 0.60 = 168 greater than 10

n(1-p) = 280(1-0.6) = 280 x 0.4 = 112  greater than 10

we use the normal dist since each of the above are greater than 10

3. n = 280

x = 182

x/n = 182/280

= 0.65

we get the test statistic z

z = [tex]\frac{0.65-0.6}{\sqrt{0.6*(1-0.6)/280} }[/tex]

= [tex]\frac{0.05}{\sqrt{0.000857} }[/tex]

=[tex]\frac{0.05}{0.02927}[/tex]

≈ [tex]1.71[/tex]

we get the p value = 1-p(z<1.71)

= 1-.9562

this gives 0.0438

4. we can see that 0.0438 < 0.10

so we conclude that over 60% of these households have at least one pet since we rejected h0.
