Answer:

She can put 7 beads on each necklace with 1 leftover

Step-by-step explanation:

Divide 22 by 3

3 cannot go into 2, so we put and X above it
3 can go into 22
3 can go into 22 seven times because 3x7 is 21
22-21 is 1
She has one bead leftover

1.Solve for w.

iren [92.7K]

Hi there,

1)
6 + (w - 10) = 5
6 + w - 10 = 5
- 4 + w = 5
w = 5 + 4

Hence, W = 9

2)
2/3 + y - 1/9 = 7/9
5/9 + y = 7/9
y= 7/9 - 5/9

Hence, Y = 2/9

4)
4x - 3/2x - 15/4 = 3/8
32x - 12x - 30 = 3
20x - 30 = 3
20x = 3 + 30
20x = 33

Hence, the answer is 33/20

5)
0.7(3s + 4) - 1.1s = 7.9
2.1s + 2.8 - 1.1 = 7.9
s + 2.8 = 7.9
s = 7.9 - 2.8

Hence, the answer is 5.1

Hope this all helps :)

zysi [14]

Answer:

y = 5; x = 1/5

Step-by-step explanation:

xy = 1 -----> x = 1/y

xy^2 = 5 -----> 1/y * y^2 = 5

y^2 / y = 5

y = 5

5x = 1

x = 1/5

Hope this Helps!

Given the triangle below, answer the following:

OLEGan [10]

Answer:

Step-by-step explanation:

question no . 5

ratio of angle L

take angle as reference angle

using cos rule

cos L = base / hypotenuse

= 4/5

ratio of angle N

take angle N as reference angle

using sin rule

sin N = opposite / hypotenuse

= 4/5

for measure of angle L

cos L = 4/5

cos L = 0.8

L = $cos^{-1}(0.8)$

L = 36.9

for meanure of angle N

sin N = 4/5

sin N = 0.8

N = $sin^{-1}(0.8)$

N = 53.1

the perimeter of a rectangle brownie pan is 50 Inches. the lenght of the pan is 5 less than twice the width. write a system of e

Serga [27]

Answer: The system of equation is,

2 ( x + y ) = 50

x = 2 y - 5

Step-by-step explanation:

Let x represents the length of the rectangular brownie and y represents the width of the rectangular brownie.

Thus, the perimeter of the brownie = 2 ( x + y )

But, According to the question,

Perimeter of the brownie = 50,

2 ( x + y ) = 50

The length of the brownie is 5 less than twice the width,

That is, x = 2 y - 5

Thus, the required system of equation is,

2 ( x + y ) = 50 , x = 2 y - 5
