Answer:

x=90 y=33

Step-by-step explanation:

similar, so you can reflect x and y across, and x is altitude so x=90

90+y+47=180

90+y=123

y=33

Answer:

2(4b-1)

Step-by-step explanation:

1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2

Answer to first step: -10+8b+8

2. Add the numbers. It should be -10 + 8 which would give you -2

Answer to second step: -2 + 8b

3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2

Answer to third step: 8b - 2

4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Answer:

[tex]y=-\frac{2}{3}x+4[/tex]

Step-by-step explanation:

First you divide every number in the equation by 3:

2x+3y=12

÷3    ÷3   ÷3

Rewrite equation:

[tex]y=-\frac{2}{3}x+4[/tex]

Hence the correct answer is [tex]y=-\frac{2}{3}x+4[/tex]

Answer:

137.13km

Step-by-step explanation:

A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:

4702² = 4700² + d²

d² = 4702² - 4700²

d = √18,804

d = 137.13 km

Answer:

5x-7 has to equal to something smaller than 13

5x-7=5

Answer: x < 4

Step-by-step explanation:

Disregarding the lesser than sign, we can treat this equation as 5x-7=13. This doesn't work all the time as there are rules, but those rules don't apply to a simple inequality such as this.

5x-7<13

5x<20

x<4

And so, our answer is x<4

Answer:

71°

Step-by-step explanation:

Line AB is parallel to line CD and that makes the angle given as 109 and the co-interior angle supplementary

since the sum of supplementary angles is equal to 180° :

180 - 109 = 71 is the measure of the co-interior angle

Answer: 1070cm2

Step-by-step explanation: Hi there

(Not taking the number of squares into account)

1. Convert 6500 millimeters to centimeters

6500mm=650cm

2. Add the area of the wood

650+210+210=1070

So the total area is 1070 cm2

Have a nice day! :)

Answer:

370

Step-by-step explanation:

Round each answer into easier to add numbers. 92 and 91 round down to 90. 9 rounds up to 10.

Answer:

aprox 280

Step-by-step explanation:

if you need to add these numbers quickly you can estimate either with an overestimation or under estimation:

for an over estimation, you can find the nearest 10 or 100 that each value is so for this you have 92 + 91 +92 +9 which is close to 100 +100+100+10

so using this you can quickly guess that it would be somewhere around 310

for an under estimation you can do the same thing but rounding down so we instead would add 90 + 90 + 90 + 10 which gives 280

now using both we know the answer would be somewhere between 280 and 310

Answer:

X =  12

Step-by-step explanation:

25 + 114 = 139

180 - 139 = 41

41 + 19 = 60

60 / 5 = 12

Answer:

Step-by-step explanation:

Identity number of addition is 0

5 + 0 = 5

0 + 3 = 3

Identity number of multiplication is 1

5 *1 = 5

1 * 15 = 15

There's no 12p in the simplification

Answer:

  about 154 square feet

Step-by-step explanation:

The area of the pool is given by the formula for the area of a circle:

  A = πr²

  A = π(7 ft)² = 49π ft² ≈ 153.94 ft²

About 154 square feet of material will be needed to cover the top of the pool.

Additional comment

The circumference of the pool is 2πr, or 14π feet -- about 44 feet.

The equation that represents the value of the car is v = $5000(1.085)^x.

Appreciation means when the value of a car increases with the passage of time. The formula that can be used to represent appreciation is:

FV = P (1 + r)^n

Where:

V = 5000(1.085)^X

We are provided , Tomas learned that a³ + b³ = (a + b ) ( a² - ab + b² ) , and his teacher writes four products on the board and we have to tell that which product suits the best if a = 2x and b = y

Now , putting a = 2x , b = y in the given formula we have :

[tex]{:\implies \quad \sf (2x)^{3}+(y)^{3}=(2x+y)\{(2x)^{2}-2\cdot x\cdot y+(y)^{2}\}}[/tex]

You have 16 quarts and 28 nickels lol

Step-by-step explanation:

Answer:

16 quarters and 28 nickels

Answer:

the answer for the first part is 260

the equation is n+8

Step-by-step explanation:

all you need to do is take the starting number witch is 13 then you add 8 and then take that number and add 8 so thats why the equation is n+8 n equaling the starting number and 8 equaling to the reoccurring number.
