Answer:

49

Step-by-step explanation:

devaughn= x+15

sydney= x

set an equation adding both their ages

x+x+15=113

2x+15=113

subtract 15 from both sides

2x=98

x=49

sydney is 49

6. The figure shows rectangle ABCD in the coordinate plane with point A(0, 2.76), B(3.87, 2.76), C(3.87,0, and D(0,0). Rectangle
maksim [4K]

Answer:

Population density = 47 people per square miles

Step-by-step explanation:

From the picture attached,

Coordinates of vertex B → (3.87, 2.76)

Which represents length of vertex A from origin O (AD)= 2.76 units ≈ 276 miles

Length of vertex B from origin O (CD) = 3.87 units ≈ 3.87 miles

Area of rectangle ABCD = Length × Width

                                         = CD × AD

                                         = 387 × 276

                                         = 106812 square miles

Population of Colorado = 5029196 people

Population density of Colorado = \frac{\text{Total population}}{\text{Total area}}

                                                     = \frac{5029196}{106812}

                                                     = 47.08

                                                     ≈ 47 people per square miles

Can someone write out the steps so I understand? <br> 14 + 18 ÷ 2 x 18 - 7
Lina20 [59]

To solve use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

REMEMBER: IF A STEP IS NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .

14 + 18 ÷ 2 x 18 - 7

Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right. In this case that would be division first then multiplication.

NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression

Division

14 + 18 ÷ 2 x 18 - 7

18 ÷ 2 = 9

14 + 9 × 18 - 7

Multiplication

14 + 9 × 18 - 7

9 × 18 = 162

14 + 162 - 7

Addition

14 + 162 - 7

14 + 162 = 176

Subtraction

176 - 7

= 169

Hope this helped!
