Answer:

<h2>Earing is $13</h2><h2>Necklace is $10</h2>

Step-by-step explanation:

Firstly, let us express the cost

for Li

5e+n=63---------1

for Jen

e+2n=36---------2

the system of equations are

5e+n=63----1

e+2n=36-----2

Multiply 1 by 1 and 2 by 5 to eliminate e we have

5e+n=63

5e+10n=180

-0-9n=-117

9n=117

Divide both sides by 9 we have

n=117/9

n=13

put n=13 in eqn 1 we have

e+2(13)=36

e+26=36

e=36-26

e=10

Earing is $13

Necklace is $10

What is the x-intercepts of the function f(x)=-2x2-3x+20

Dmitry [639]

Hey,
The x-intercepts are the coordinates where the line intercepts the x-axis.

x-intercepts: $( \frac{16}{3}, 0)$

Cheers,

a gym has 275 members 40% are bronze members 28% are silver members the rest are good work out the gold members

statuscvo [17]

STEP 1:
Find % of gold members. Subtract the known % of bronze and silver members from 100%.

x= percent of gold members

x= 100% - (40% +28%)
x= 100% - 68%
x= 32% percent of gold members

STEP 2:
Find number of gold members. Multiply % of gold members by the total numbers of members (275).

x= # of gold members

x= 275 * 32%
x= 275 * 0.32
x= 88 gold members

Hope this helps! :)

Please help me with this question

MrMuchimi

Answer:

x = 9

Step-by-step explanation:

when two lines intersect, it creates four angles. vertical angles are the angles that are opposite to each other. in the attached image, 1 & 3 are vertical angle pairs, and so are 2 & 4.

since vertical angles are always congruent, 3x - 8 is equal to 2x + 1

3x - 8 = 2x + 1

add 8 to each side

3x = 2x + 9

subtract 2x from each side

x = 9

check your answer:

3x - 8 = 2x + 1

3(9) - 8 = 2(9) + 1

27 - 8 = 18 + 1

19 = 19
