Answer:

<ZUVW = 12 degrees

<ZXYZ = 78 degrees

Step-by-step explanation:

x - 10 + 4x - 10 = 90

5x -20 = 90

5x = 90 + 20

x = 110/5

x = 22

mZUVW = 22 - 10 = 12 degrees

mZXYZ = 4(22) - 10

= 78

Answer:

5 times the compared amount.

Step-by-step explanation:

Answer:

The ratio means for everything 5 of something (lets call it x), y will always have 1.

Example - Jordan buys 5 cookies from the bakery. The special offer of the day allows him to receive one free brownie. This is an example of 5/1 because  every 5 cookies, Jordan receives 1 brownie.

Answer:

(0,0) and (6,12)

Step-by-step explanation:

8x - x^2 = 2x

8x -2x -x^2 =0

6x -x^2 = 0 then factor out a common x

x (6-x) = 0

so x =0 or 6-x=o

x=6

so if x=o y=2x=2(0)=0

and if x=6 y =2x =2(6)= 12

Answer:

the first option

Step-by-step explanation:

to find a set of ordered pairs that are not a function you would want to look at all the x-intercepts and find the order that has more than one number repeating itself like 1 in the first option

Answer:

in two bouquets of flowers there would be, 12 roses and 20 white carnations.

Step-by-step explanation:

In each bouquet there are 6 roses and 10 white carnations, if there's 2 bouquets of flowers that means that there 2 x 6 and 2 x 10.

2 x 6 (or 6 + 6) = 12

2 x 10 (or 10 + 10) = 20

so in two bouquets there are 12 roses and 20 white carnations.

because in a single bouquet there are 6 roses and 10 white carnations so just double it!

hope that helps

Answer:

The length of the longer base is a. 33 in

Step-by-step explanation:

This is true because if the longer base is 3 more inches than 2 times the amount of the shorter base, all you have to do is 15 x 2 + 3 = 33 in

Hope it helps! =)

Answer: A or 33inches

Step-by-step explanation

First write expressions for the longer base

Longer base: 3 + 2x

Shorter base: x

then solve

If x = 15 then..

3 + 2x

3 + 2(15)

3 + 30

33

THE LONGER BASE IS 33 INCHES

The line segment AD measures 13 units.

What is a line segment?

A line segment in geometry has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.

A line segment AD is given.

Four points A, B, C and D are placed.

It is given that measurement of BC = 3 units.

Also, measurement of BD = 10 units.

Since, B is the midpoint of AC, so -

AB = BC

So, the measurement of AB = 3 units

The measurement of CD can be found as -

CD = BD - BC

CD = 10 - 3

CD = 7 units

So the measurement for line segment AD is -

AD = AB + BC + CD

AD = 3 + 3 + 7

AD = 13 units

Therefore, the measurement value is 13 units.

Answer:

17.) x = 3

18.) x = -5

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3

Step-by-step explanation:

All you really have to do for all of the problems is substitute your value of "x" for the function.

17.) f(x) = 8x - 7; f(x) =17

    17 = 8x -7  ---- substitute 17 for f(x), add 7 on both sides

    24 = 8x ------ divide 8 on both sides

    x = 3

18.)    g(x) = -4x + 7; g(x) = 27

           27  = -4x + 7  substitute 27 for g(x), subtract 7 on both sides

           20 = -4x

            x = -5

Answer:

[tex]Their \: sum \: is -334[/tex]

[tex]x + x+1 + x+2 + x+3 = -334[/tex]

[tex]4x + 6 = -334[/tex]

[tex]4x = -340[/tex]

[tex]x = -85 [/tex]

Step-by-step explanation:

[tex]Thanks!!!!![/tex]

Answer:

the first number is x (x ∈ Z)

=> four consecutive integers are x, x + 1, x +2, x + 3

because the sum of them = -334, we have:

x + (x + 1) + (x + 2) + (x + 3) = -334

⇔ 4x + 6 = -334

⇔ 4x = -334 - 6 = -340

⇔ x = -340/4

⇔ x = -85

=> 4 consecutive integers are -85; -84; -83; -82

C. 9

Step-by-step explanation:

15/100*60

3/20*60

180/20

9

Answer:

The answer is 9

Step-by-step explanation:

15% * 60

"OF" mean multiplication so we multiple

¹⁵/100 * 60

we cancel "Zero cancel Zero"

we left with

¹⁵/10 * 6

but we can make the fraction to be uniform

so we say ¹⁵/10 * ⁶/1

we multiply

15 * 6=90

10 * 1=10

⁹⁰/10

we divide

10 into 90 is 9

10 into is 1

so we say ⁹/1 is the same as 9.

Hence our answer is 9

The constant of proportionality that relates the number of miles y, to the number of days x is [tex]\frac{1}{7}[/tex] .

What is proportionality?

 In general, the word "proportion" is used to describe a part, share, or amount that is compared to an entire. Two ratios or fractions being equal is expressed by an equation or a statement. An analysis of two numbers in terms of their proportion. A ratio is said to be directly proportional to another if two sets of supplied numbers are increasing or decreasing in the same ratio. With the "::" or "=" symbol, proportions are indicated.

Here if the days are increasing then distance also increased . Then days directly proportional to the distance .

=> Number of days ∝ Total distance

=> x∝y

To remove proportion we hate to add constant K.

=> x= ky

Here if he runs 28 miles in 4 days. x=4, y=28.

=> 4 = k*28

=> k = 4/28

=> k = [tex]\frac{1}{7}[/tex]

the equation is x = [tex]\frac{1}{7}[/tex]y

Hence  the constant of proportionality that relates the number of miles y, to the number of days x is [tex]\frac{1}{7}[/tex] .

Answer:

The greatest Common factor of 52/65 is 13!

Step-by-step explanation:

Hope this helps :)

Pls make brainliest :p

And have an amazing day <3

Answer:

13

Step-by-step explanation:

The GCF of numbers can be found by first finding the prime factors of the numbers.

52 = 2^2 * 13

65 = 5 * 13

The GCF is the product of common factors with lower exponent.

The only common factor is 13.

GCF = 13

To reduce the fraction, divide the numerator and the denominator by the GCF.

(52/13) / (65/13) = 4/5

Answer:

shade the square that is 1 above the bottom right

To make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same. Many geometrical shapes appear to be symmetrical when they are rotated 180 degrees or with some angles, clockwise or anticlockwise.

Given is a figure of square box, of 5x5, we need to complete the shaded part so, that the resulting figure will be rotational symmetric,

Since, the figure needs to be rotational symmetric, that means, the figure will be same no matter how many times we rotated it,

If we shade the one square which is the last box of the fourth line, then it will be a figure which is rotational symmetric.

Hence, to make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

7x -1 +6x -1 = 180, group like terms

7x+6x -1 -1 = 180, combine like terms

13x -2 = 180, add 2 to both sides

13x -2+2 = 180+2 , solve the additions

13x = 182, divide both sides by 13

13x/13 = 182/13, solve the divisions

x = 14
