50 Points What is the value of r? 6.4r−5.9r=−3.25 Question 1 options: A -6.5 B 6.5 C -3

Oliga [24]

Answer:

Option A. -6.5

we have

$6.4r-5.9r=-3.25$

Solve for r

That means ---> isolate the variable r

Combine like terns left side of the equation

$0.5r=-3.25$

Divide by 0.5 both sides

$0.5r/0.5=-3.25/0.5$

$r=-6.5$

Paolo is using his grandmother's breakfast bar recipe. He always doubles

Papessa [141]

Answer:

$6\frac{1}{3}$ = $2\frac{1}{2}$ * 2 + $\frac{x}{2}$

Step-by-step explanation:

lets start with what we know.

the recipe calls for 2 $\frac{1}{2}$ cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2

2 $\frac{1}{2}$ * 2 = 5 cups of yogurt.

the total of yogurt and oats is $6\frac{1}{3}$ and we know how much yogurt we have so we subtract that from the total of both.

$6\frac{1}{3}$ - 5 = $1\frac{1}{3}$

the oats after doubling were $1\frac{1}{3}$ cups so u divide it by 2

$1\frac{1}{3}$ / 2 = $\frac{2}{3}$ before doubling
