But do not forgot if they are across from eachother they equal the same thing, notice how these two angles look the exact same so the answer will be 82

X = 82

a corresponding angle of 82 is also the vertical angle to x. This makes then equal.

Lauren has a bouquet of flowers. 1/5 of the flowers are red. 3/10 of the flowers are white. The rest are yellow. Lauren’s bouque

ss7ja [257]

Answer:

36 flowers

Step-by-step explanation:

Given

$Red = \frac{1}{5}$

$White = \frac{3}{10}$

$Yellow = 18$

Required

Determine the number of flowers

First, we need to determine the fraction of flowers that are yellow;

$R + W + Y = 1$

$\frac{1}{5} + \frac{3}{10} + Y = 1$

$\frac{2+ 3}{10} + Y = 1$

$\frac{5}{10} + Y = 1$

$Y = 1 - \frac{5}{10}$

$Y = \frac{10 -5}{10}$

$Y = \frac{5}{10}$

$Y = \frac{1}{2}$

Let the number of flowers by N;

The yellow flowers can be represented as;

$18 = \frac{1}{2} * N$

Solve for N

$N = \frac{18 * 2}{1}$

$N = \frac{36}{1}$

$N = 36$

Waheeda wants to buy a skateboard. She has $15 in savings. A skateboard costs $75. How much more money does she need? Write and

erica [24]

Answer and Explanation:

Suppose Waheeda needs x more dollars.

Right now, she has $15. She needs x more, so we add x to 15. The end result we hope to have is $75. So, the equation is:

x + 15 = 75

To solve, we simply subtract 15 from both sides: x = 75 - 15 = 60

Thus, she still needs $60.

Hope this helps!

The area of a triangle piece of stained glass is 50 centimeters if the height of the triangle is four times the base, how long a

gavmur [86]

Answer:

Base = 5 cm

Height = 20 cm

Step-by-step explanation:

Points to remember

Area of triangle = bh/2

Where b - base of triangle

h - Height of triangle

<u>To find the Height and Base of given triangle</u>

It is given that,area of a triangle piece of stained glass is 50 centimeters

the height of the triangle is four times the base

h = 4b

Area = bh/2

50 = (b * 4b)/2

100 = 4b²

b² = 100/4 = 25

b =√25 = ±5

b = 5 then h = 4b = 4 * 5 = 20

Base = 5 cm and Height = 20 cm

what is the value of y for the line that has a slope of 1 and goes through the points (-4,y) and(-2,8)

kozerog [31]

Answer:

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the slope m = 1 and the points (-4, y) and (-2, 8). Substitute:

$1=\dfrac{8-y}{-2-(-4)}$

$1=\dfrac{8-y}{2}$ <em>multiply both sides by 2</em>

$2=8-y$ <em>subtract 8 from both sides</em>

$-6=-y$ <em>change the signs</em>

$6=y\to y=6$
