How do you solve 0.8=6-2.5x

2 answers:

6 0

X=2.08

To solve you need to first get x by itself. To do that you want to subtract 6 from both sides (get 6 away from x and put on other side) which will leave you with -5.2=-2.5x next isolate x by dividing -2.5 on both sides to then get 2.08=x

Answer:

BEDMAS

Step-by-step explanation:

The order of operations for any and every equation is BEDMAS:

Brackets - none exist here

Exponents - none exist here

Division/Multiplication - "2.5x"

Addition/Subtraction - "+6-2.5x"

When isolating a variable, order of operations is reversed:

Addition/Subtraction:

Move +6 to the left side by subtracting it:

5.2 = -2.5x

Division/Multiplication:

Divide "-2.5x" by -2.5 to isolate x:

x = 5.2/-2.5

x = 2.08

A cookie factory uses 1 1/5 bags of flour in each batch of cookies. the factory used 7 1/5 bags of flour yesterday. how many bat

Hello!

To find how much batches of cookies the factory made, we need to divide the total number of bags of flour used by how many bags of flour are needed for one batch of cookies.

Before dividing, we need to convert the complex fraction into an improper fraction.

1 1/5 → 5 × 1 + 1 = 6/5

7 1/5 → 5 × 7 + 1 = 36/5

For every batch of cookies, the factory uses 6/5 bags of flour. Yesterday, the factory used 36/5 bags of flour.

Remember when dividing by a fraction, it is like multiplying its reciprocal. This means that the second fraction is flipped, then which it can be multiplied together.

$\frac{36}{5} / \frac{6}{5}$ → $\frac{36}{5} * \frac{5}{6} = \frac{180}{30} = 6$
