7+2x/3=5 .............
borishaifa [10]

Answer:

x= -3

Step-by-step explanation:

7 + 2x/3 = 5

Subtract 7 from both sides,

2x/3 = 5-7

2x/3 = -2

Multiply by 3,

2x = -2*3

Divide by 2,

x = -2*3 / 2

x = -3

Sophia exchanged 1000 U.S. dollars for the South African currency, which is called the rand. The exchange rate was 7.15 rand to
dolphi86 [110]
Part a:-

7.15 rands = 1 dollar

So we are going to MULTIPLY to find out how many rands there are going to be.

1000 × 7.15 = <span>7150

<span>So, 7150 rands is your answer. 

Part b:-

To do this first we will DIVIDE. 

6274 </span></span>÷ 7.15 ≈ <span>877.482.......

So, 6274 rands is ABOUT $878.

Par a:- 7150 rands

Part b:- about $878.

Hope I helped ya!!!!!</span>

The equation y=2(x-1)^2-5y=2(x−1)
marin [14]

Answer:

(b) It is symmetrical about x = 1

Step-by-step explanation:

Given

y = 2(x - 1)^2 - 5

See attachment for options

Required

True statement about the graph

First, we check the line of symmetric

y = 2(x - 1)^2 - 5

Expand

y = 2(x^2 - 2x + 1) - 5

Open bracket

y = 2x^2 - 4x + 2 - 5

y = 2x^2 - 4x -3

A quadratic equation y = ax^2 + bx + c has the following line of symmetry

x = -\frac{b}{2a}

By comparison, the equation becomes:

x = -\frac{-4}{2*2}

x = \frac{4}{4}

x = 1

Hence, the line of symmetry is at: x = 1

(b) is true.

RS = 3x + 17, MN = 7x - 15
Fofino [41]

Answer:

Step-by-step explanation:

RS ≡ MN

 3x + 17 = 7x - 15

- 3x          - 3x

         17 = 4x - 15

      + 15        + 15

         32 = 4x

          4      4
