Answer: Ashley has $20

Chau has $15

Rueben has $40

Step-by-step explanation:

Let x represent the amount that Ashley has.

Let y represent the amount that Chau has.

Let z represent the amount that Rueben has.

Ashley,chau, and reuben have a total of $ 75 in their wallets. This means that

x + y + z = 75- - - - - - - - -- - -1

Chau has $5 less than ashley. This means that

y = x - 5

Reuben has  2 times what ashley has. This means that

z = 2x

Substituting y = x - 5 and z = 2x into equation 1, it becomes

x + x - 5 + 2x = 75

4x = 75 + 5 = 80

x = 80/4 = 20

y = x - 5 = 20 - 5

y = 15

z = 2x = 2 × 20

z = 40

How do you solve this? Please helppp what’s the answer???
ANEK [815]

Answer:

I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

1. In the given figure. BEST is a cyclic quadrilateral. ES is produced so that BE=SN. If ET is the bisector of angle BES, prove
padilas [110]

The triangle NET is an <em>isosceles</em> triangle as <u>ET</u> ≅ <u>TN</u> and ET = TN < EN given the condition that BEST is a <em>cyclic</em> quadrilateral.

<h3>How to determine the existence of an isosceles triangle</h3>

In this question we must apply <em>geometric</em> properties of angles and triangles to determine that the triangle NET is an <em>isosceles</em> triangle. <em>Isosceles</em> triangles are triangles with two sides of equal length. In addition, we must apply the geometric concept of proportionality.

Now we proceed to prove the existence of the isosceles triangle:

  1. <u>BE</u> ≅ <u>SN</u>       Given
  2. ET is the bisector of ∠BES     Given
  3. ET/ES = ET/EB     Definition of proportionality
  4. ES = EB       (3)
  5. <u>ES</u> ≅ <u>EB</u>     Definition of congruence
  6. <u>ET</u> ≅ <u>TN</u>     SSS Theorem/Result

Therefore, the triangle NET is an <em>isosceles</em> triangle as <u>ET</u> ≅ <u>TN</u> and ET = TN < EN given the condition that BEST is a <em>cyclic</em> quadrilateral. \blacksquare

What is the first step to solve the following system of equations using substitution? 3x+y=15 5x-3y=11Divide the second equation
Nina [5.8K]

Answer:

(4, 3)

Step-by-step explanation:

#1. Isolate x:

3x + y = 15

y = 15 - 3x

Substitute and solve for x:

5x - 3y = 11

5x - 3(15 - 3x) = 11

5x - 45 + 9x = 11

5x + 9x = 11 + 45

14x = 56

x = 4

Substitute and solve for y:

y = 15 - 3x

y = 15 - 3(4)

y = 15 - 12

y = 3
