Simplify both sides of the equation.
(−7.8)(x)+(−7.8)(6.5)=−25.74 −7.8x+−50.7=−25.74 -> −7.8x−50.7=−25.74
Add 50.7 to both sides.
−7.8x−50.7+50.7=−25.74+50.7 -> −7.8x = 24.96
Divide both sides by -7.8.
−7.8x /−7.8 = 24.96/−7.8
And as a decimal
X= −3.2

Hope this helped. (got taken off because I did the steps? oo well)

Three fourths minus three eighths equals

MrRissso [65]

Answer:

3/8

Step-by-step explanation:

With unlike denominators find the Least Common Denominator (LCD)

LCD = 8

Multiplying numerators and denominators to get the LCD in all fraction denominators

=3/4 times 2/2−3/8

Then rewriting the equation with the equivalent fractions

=6/8−3/8

With like denominators we can operate on just the numerators

=6−3/8

=3/8

Billy bob uses a 10-square model to find 20% of 80. what is 20% of 80? EXPLAIN how Billy Bob can use this model to find 20% of 8

Dvinal [7]

Percentages are numbers that are units of 100

The value of 20% of 80 is 16

<h3>How to determine the percentage value</h3>

The model is not given.

However, the percentage value can still be calculated

The expression is given as:

$20\%\ of\ 80$

Express of as product

$20\%\ * 80$

Express 20 % decimal

$0.20* 80$

Evaluate the product

Hence, 20% of 80 is 16
