90 POINTS- Please help with this geometry question! I have the answer because I assumed it was congruent, but I don't have the statement reasons.

Answer:

Step-by-step explanation:

There is not a table to look at.

But, if she saves $3 a week. 35/3= 11.6. It'll take her 11.6 or 12 weeks to save up $35.

Answer:

12 weeks

Step-by-step explanation:

She earns $5 each week, but she only saves $3. This would mean that she saves $3 a week and with a end goal of $35, it would take 11.6 weeks, which would round up to 12.

Hope this helps :)

Answer:

4, 10, 15

Step-by-step explanation:

Because 4 plus 10 is less than 15

Answer:

−3X−30

Step-by-step explanation:

Answer:

51 cm

Step-by-step explanation:

perimeter = 2 * length + 2 * width

226 = 2 * 62 + 2 * width

226 = 124 + 2 * width

226 - 124 = 2 * width

102  = 2 * width

102/2 = width

51 = width

Answer:

2 dollars each duh

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the time it will take Alfonso be x

Let the time it will take Zoe be y

If Alfonso does a job in 30 hours more than Zoe, then;

x = 30+y...... 1

Also if they can do the job together in 8 hours, then;

x+y = 8.... 2

Substitute 1 into 2;

x+y=8

30+y+y = 8

40+2y = 8

2y = -32

y = -16

Hence X = 30-16

X = 14

y = 30+14 = 44

hence it will take Alfonso about 44hours to do the work alone

Answer:

y = 1/3x - 3/4

Step-by-step explanation:

Create a slope triangle or just count the amount of squares between each highlighted point. And then see where the line intersects on the y-axis.

Answer:

Sorry not sure but try y-6= -1 (x - 3)

Step-by-step explanation:

Answer: B

Step-by-step explanation:

Given:

Eighteen 2.5 gallon buckets are needed to fill a cistern with water.

To find:

The constant of variation.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

Where, k is constant of variation.

In the given problem, water in cistern (w) is directly proportional to number of buckets (n).

[tex]w\propto n[/tex]

[tex]w=2.5n[/tex]        (Capacity of each bucket is 2.5 gallons)

Therefore, the constant of variation is 2.5.

Answer:

45

Step-by-step

I just did 18 * 2.5!

It a simple answer!

The quantites are inversely so that means you multiply the numbers. Like 18 * 2.5. That's how I got 45

Finding the value of x

16x-3=8+9x+45

Explanation

We know that the,

Sum of interior angles =exterior angles

→16x-9x=45+3+8

→7x=56

→x=56/7

→x=8

Hope my answer helps uh!

Answer:

Step-by-step explanation:

x= -3

Answer:

1. x= -4

2. x= 18

3. x= -15

4. x = 6

Step-by-step explanation:

Use relationship of angles to create equations and solve for x

You need to pay attention to see if the sides will be equal to each other or equal to 180

first picture on top left is x = -4

second picture on top right is x = 19/2

third picture on bottom left is x = -5

fourth picture on bottom right is x = 166/41

Answer:

both anges are 105

x = 128

Step-by-step explanation:

This is based on a theorem called F-angles.

If a and b are parallel, then these angles are equal.

So x = 105+23 = 128

Answer:

D. [tex]\frac{1}{27}[/tex]

Step-by-step explanation:

[tex]3^{-3}[/tex] = [tex]\frac{1}{27}[/tex]. First you need to remove the negative exponent, to do this move the term into the denominator. [tex]\frac{3^{-3} }{1}[/tex] becomes [tex]\frac{1}{3^{3} }[/tex], then solve for [tex]3^{3}[/tex], which equals 27. So your answer is [tex]\frac{1}{27}[/tex].

Step-by-step explanation:

y - y1 = m (x - x1)

(y - y1)/m = x - x1

x - x1 = (y - y1)/m

x = (y - y1)/m + x1

therefore, answer is option C

Answer:

7 and 22

Step-by-step explanation:

The Sum of any Two Sides of a Triangle is Greater than the Third Side.

The third side = x

x < 8 + 15

x < 23

8 < x + 15

Can be any number in between 1 and 22.

15 < x + 8

Should be a number in between 7 and 22.

Answer:

B

Step-by-step explanation:

Kinda complex to explain without a graph but its the answer

Answer:

2x+7=-3+2x multiply what’s in the bracket by the negative sign

Collect like terms

2x-2x=-3-7, so

0=-10

Step-by-step explanation:

I hope this is the answer, if it helped please give me brainliest

Answer:

Step-by-step explanation:

If it is irrational, it can never be rational unless it is acted upon by something else like a power.

Pi, no matter what is done to it, can never be rational.  Once a number is declared as irrational, that is what it remains.

Answer:

Thevalue of x-intercept is 0

and y intercept is-6.

Step-by-step explanation:

here,9x+6y=-36

9x = -36 - 6y

x=(-36 -6y)/9

x=(-12-2y)/9.........(i)

putting value of x in question

9[(-12-2y)/9]+6y=-36

-12-2y+6y= -36

-12+4y= -36

4y=-24

y=-6

puting value of x in equation (i)

x=(-12-2y)/9

x=(-12-2×-6)/9

x=0

I have done your task. But i think it will help you. if it helps please my answer as brainliest answer.

please do .... for my hard work.

Answer: Ratios

Step-by-step explanation:

Zalika can work out this estimate by using the ratio of carp to pike that she first caught. This is how to use the ratios:

1) 120 carp : 16 pike --> from given information

2) 136 fish : 16 pike --> add the numbers together to get total fish compared to pike

3) Multiply by 250 --> 34000 divided by 136 is 250

4) 34000 fish : 4000 pike --> 16x250=4000

ok if you subtract u will get your answer

Answer:

The sides are 24cm, 7cm, and 25cm

Step-by-step explanation:

3x+x-1+3x+1=56 <---- First we combine like terms (the 1's cancel out)

7x/7=56/7 <--- Divide by 7 to isolate the variable

x=8 <--- Now that we've solved for x we need to plug it back into each side

3(8)=24

(8)-1=7

3(8)+1=25

24+25+7=56 <---- Make sure it all adds up to 56

Hope this helps :)

Answer:

The sides of the triangle are:

Step-by-step explanation:

As the sides are given

so the equation of the perimeter becomes

[tex]P=3x+\left(x-1\right)+\left(3x+1\right)\:[/tex]

as

so

[tex]56=3x+\left(x-1\right)+\left(3x+1\right)[/tex]

[tex]3x+x+3x-1+1=56[/tex]

[tex]7x-1+1=56[/tex]

[tex]7x=56[/tex]

[tex]\frac{7x}{7}=\frac{56}{7}[/tex]

[tex]x=8[/tex]

Now finding the sides

[tex]3x = 3(8)=24[/tex]

[tex]x-1=8-1=7[/tex]

[tex]3x+1=3(8)+1=25[/tex]

Therefore, the sides of the triangle are:

Answer:

b=35°

Step-by-step explanation:

complementary angles add up to 90°

a+b=90°

55°+b=90°

-55 -55

b=35°

hopefully this helps :)
