What is the value of x? Four-fifths x minus StartFraction 1 Over 10 Endfraction = StartFraction 3 Over 10 EndFraction One-fourth
Sedbober [7]

Answer:

<h3>1/2</h3>

Step-by-step explanation:

Given the expression

4/5 x - 1/10 = 3/10

We are to find the value of x

4/5 x = 3/10 + 1/10

4/5 x = 4/10

Cross multiply

4x * 10 = 5 * 4

40x = 20

x = 20/40

x = 1/2

The value of x is 1/2

What is the value of G in the center and how do you solve it?
Mademuasel [1]
First solve:
7 + 3c = -11 --> c = -6
-9 - a/4 = 5 --> a = -56
b/5 +9 = 6 --> b = 75

second, solve:
a/f = -7 --> substitute -56 in for a --> -56/f = -7 --> f = 8
b/e = 3 --> substitute 75 in for b --> 75/e = 3 --> e = 25
3 = c/d --> substitutie -6 in for c --> 3 = -6/d --> d = -2

third solve:
g = d+e+f --> substitute -2 in for d, 25 in for e, and 8 in for f.
g = -2 + 25+8 
g = 31

The property for the missing justification is: A. addition property of equality.

<h3>What is the Addition Property of Equality?</h3>

If b - a = c, based on the addition property of equality, we can isolate b by adding a to both sides, i.e. b - a + a = c + a, to give us b = c + a.

Using the addition property of equality, 7 was added to both sides of the equation as shown in step 3.

Therefore, the missing justification is: A. addition property of equality.
