Can someone help me understand this question?

Hey there!

For Part A, because the amount earned on Sunday isn't specified, we can call this additional income x. Because we're writing an expression, we don't need an equal sign. The expression will be (x + 14).

For Part B, "2 less than" will mean "– 2" and "twice than" will mean the amount of dogs that Alicia walked times 2. We can call the amount that Alicia walked y to avoid confusion with the last expression (though you could use whatever variable here) and your expression will be (2y – 2).

Hope this helped you out! :-)

Alvin is 7 years older than Elga. The sum of their ages is 97. What is Elga's age?

LenaWriter [7]

Elga's age = x

Alvin's age = x + 7

x + x + 7 = 97.

Simplify the left side of the equation

2x + 7 = 97.

Subtract 7 from each side

2x = 90.

Divide each side by 2

x = 45

Since x is equal to Elga's age, Elga is 45 years old

NO LINKS!!! 14. Consider the table

iVinArrow [24]

Answer:

(a) rate of change = 8

(b) Function: y = 8x

Range: 0 ≤ y ≤ 16

Explanation:

Looks like a inverse variation sequence.

Inverse Variation formula: y = k(x)

Take two points: (1, 8), (2, 16)

Find the value of k which is constant also considered as rate of change.

Insert values:

8 = k(1)

k = 8

===========

16 = k(2)

k = 8

Equation: y = 8x

Domain lies in the x axis, Range lies in the y axis.

Here domain: 0 ≤ x ≤ 2

Here range: 0 ≤ y ≤ 16

Is 0.069 less than 0.07

Nuetrik [128]

Yes, 0.069 is less than 0.07~

First, we compare the "one" place: 0 = 0.

Second, we compare the "tenth" place: 0 = 0.

Next, we compare the "hundredth" place: 6 < 7.

Because 6 < 7, 0.069 < 0.07 as a result~

-12+x-34=60 If you like this question please rate this five stars! Thank you!

natulia [17]

Answer:

x=106

Step-by-step explanation:

Let's solve your equation step-by-step.

−12+x−34=60

Step 1: Simplify both sides of the equation.

−12+x−34=60

−12+x+−34=60

(x)+(−12+−34)=60(Combine Like Terms)

x+−46=60

x−46=60

Step 2: Add 46 to both sides.

x−46+46=60+46

x=106

You are renting a surfboard for the day. The surfboard rental fee is $25 with an additional charge of $7 per hour. You have at m

o-na [289]

Initial fee: $25

Per hour fee: $7

Your budget: $60

x = # of hours you can rent the surfboard

$25 + $7x ≤ $60

Subtract $25 from both sides.

$7x ≤ $35

Divide both sides by $7

x ≤ 5

You can rent the surfboard for less than or equal to 5 hours.
