The value of y from the given equation if x is 0.5, is 450

<h3>What is an equation?</h3>

They are expressions separated by an equal sign

Given the linear regression for a calibration curve expressed as:

y=1500x – 200

If the value of x is 0.5, then;

y = 1500(0.5) - 200

y = 750 - 200

y = 550

Hence the value of y if x is 0.5, is 450

Andrea has a goal of running at least 50 miles this month. She has already run 7 miles. How many miles does Andrea need to run e

Nuetrik [128]

Answer:

At least 1.72 miles per day.

Step-by-step explanation:

Given: Goal of running is at least 50 miles in a month.

Andrea have already run 7 miles.

Days left in the month is 25.

As given, Andrea have already run 7 miles.

∴ Andrea need to run this month= $50\ miles - 7\ miles= 43\ miles$

Days remaining this month is 25.

Now, finding miles need to run each day to meet her goal.

Miles need to run each day= $\frac{remaining\ miles}{remaining\ days}$

⇒ Miles need to run each day= $\frac{43}{25} = 1.72\ miles$

∴ Andrea need to run at least 1.72 miles to meet her goal this month.

15+9=? (5+3) What number is missing from the expression?

Airida [17]

Answer:

<h3> $\boxed{ \boxed{ \bold{ \mathsf{3}}}}$ </h3>

Step-by-step explanation:

Let the missing number be 'x'

⇒ $\mathsf{15 + 9 = x(5 + 3)}$

Distribute x through the parentheses

⇒ $\mathsf{15 + 9 = 5x + 3x}$

Swap the sides of the equation

⇒ $\mathsf{5x + 3x = 15 + 9}$

Add the numbers

⇒ $\mathsf{5x + 3x = 24}$

Collect like terms

⇒ $\mathsf{8x = 24}$

Divide both sides of the equation by 8

⇒ $\mathsf{ \frac{8x}{8} = \frac{24}{8} }$

Calculate

⇒ $\mathsf{x = 3}$

Hope I helped!

Best regards!

Mila [183]

To find the original price, you could use a variable to represent the original price in this equation;

Let p represent the original price

.70 × p=11.20

to solve this, we'd isolate the variable (p)

p=11.20 ÷.70

p=16

The original price was $16
